1.1.3 Compatible Receivers

AT9S Pro is a 10 channels transmitter, support 2.4G DSSS and FHSS dual hybrid spread spectrum, 16

channels pseudo random frequency hopping.

AT9S Pro sells with receiver R9DS.

R9DS is a 9 channels receiver when working with PWM signal(red LED), it will a 10 channels receiver when

working with S-BUS signal(purple/blue LED).

Besides R9DS, AT9S Pro is also compatible with Radiolink R6DS, R10DS, R12DS and super mini 10

channels receiver R6DSM and 12 channels mini dual antenna receiver R12DSM.

R6DS, is a 6 channels receiver when working with PWM signal while it is a 10 channels receiver when

Radiolink Electronic Ltd

www.radiolink.com

working with SBUS or PPM signal.

R12DS, is a 11 channels receiver when working with PWM signal while it is a 12 channels receiver when

working with SBUS signal.

Note AT9S Pro is default 10 channels, you can upgrade it to 12 channels with USB cable. You have to setup

AT9S Pro to 12 channels first if you use 12 channels receivers R12DS or R12DSM while you have to setup

AT9S Pro back to 10 channels when you use 10 channels receiver R6DS, R6DSM and R10DS.

To setup to 12 channels: power on your AT9S Pro--Press Mode button one second into BASIC MENU--into

SYSTEM menu--change CH-SELECT from 10CH to 12CH.

Since Radiolink radio control systems are not open source, that Radiolink transmitters just compatible with

Radiolink receivers and vice versa.

1.1.4 Connection with TBS Crossfire TX

1 Power on the transmitter- Long press the Mode key to enter the BASIC MENU->Rotate the Scroll

Dial to highlight the SYSTEM option and depress the Enter key->Select the OUT and change the output as

1.2 RADIO INSTALLATION

1.2.1 Guidelines to mount the servos, receiver and battery

• Make certain the alignment tab on the battery, switch and servo connectors is orient correctly and ‘key’ into

the corresponding notch in the receiver or connectors before plugging them in .When unplugging connectors,

never pull on the wires. Always pull on the plastic connector instead.

• Receiver’s Antenna: In generally receiver’s antenna is longer than remote control, don’t break or retract it,

otherwise shorten the control distance. The antenna must be kept away from conductive materials, such as

metal. Please make distance test before flying.

• If your aileron servos are too far away to plug into the receiver, use an aileron extension cord to extend the

length. Avoid plugging multiple extensions together to obtain your desired length. If the distance is greater

than 50cm or high current draw servos are being used, use heavy servo extensions.

• Receiver Vibration and Waterproofing: the receiver contains precision electronic part. Be sure to avoid

vibration, shock, and temperature extremes. For protection, wrap the receiver in foam rubber or other

vibration-absorbing materials. It is also a good idea to waterproof the receiver by placing it in a plastic bag and

securing the open end of the bag with a rubber band before wrapping it with foam rubber. If you accidentally

get moisture or fuel inside the receiver, you may experience intermittent operation or a crash. If in doubt,

please contact Radiolink aftercares or distributors for service.

• Always mount the servos with the supplied rubber grommets. Don’t over tighten the screws. No part of the

servo casing should contact the mounting rails, servo tray or any part of structure. Otherwise vibration will be

transmitted to the servo causing damage of servo. Note the small numbers (1, 2, 3, and 4) molded into each

arm on the servo arms. The number indicate how many degrees each arm is ‘off’ from 90 degrees to correct

for minute manufacturing deviations from servo to servo.

• To center the servos, connect them to receiver and turn on the transmitter and receiver. Center the

trims on the transmitter, then find the arm that will be perpendicular to the pushrod when placed on the servo.

Radiolink Electronic Ltd

www.radiolink.com

•After the servos are installed, operate each servo over its full

travel and check that the pushrods and servo arms don’t bind or

contact each other. Also make sure the controls do not require

excess force to operate. If there is an objectionable buzzing sound

coming from a servo, there is probably too much resistance in the

control. Find and correct the problem. Even is there is no servo

damage, excess battery drain will result.

• Use the mounting plate from the receiver on/off switch as a

template for the cutout and screw holes, mount the switch on the

side of the fuselage opposite the engine exhaust, and where it

won’t be inadvertently turned on or off during handling or storage.

Be certain the switch moves without restriction and ‘snaps’ from

ON to OFF, and that the cutout allows full motion of the switch in

both directions.

• When install the switch harness to the helicopter please use

the switch cover. Generally sandwich the frame between the

switch and switch cover and securely tighten the screws, Different

models might require different installations. If so, please follow the

model’s instruction manual.

• To prevent the servo lead wires from being broken by vibration during flight, provide a slight amount of

slack or extra so that the wire sticks out slightly and fasten it at suitable points. In addition, periodically check

the wire during daily maintenance.

The above listed receiver and channels is referred to the channel 1~9 of the receiver R9DS, connect the

receiver with the related servo, you can control the servos by the correspondent switch.

To be clear, the servo connected with the receiver channel 1 is controlled by the radio aileron lever; servo

connected with channel 2 is controlled by elevator lever; servo connected with channel 3 is controlled by

throttle stick; servo connected with channel 4 is controlled by the rudder lever. Channel 5~9 can be self-set

with the related switches by the menu AUX-CH, and the sub menu. For channel 9, the LED indicator on the

receiver flashes blue for S-BUS signal and red for PWM.

1.2.3 Installment of antenna

Installment of antenna

1. Receiver Antenna Installment

1 Keep antennas as straight as possible, or the effective control range will reduce.

2 Big models may contain metal parts that influence signal emission. In this case, antennas should be

positioned at both sides of the model to ensure the best signal status in all circumstances.

3 Antennas should be kept away from metal conductor and carbon fiber at least half inch away and no

over bending.

4 Keep antennas away from motor, ESC or other possible interference sources.

5 Press and hold the ID SET for more than one second and receivers will start to work with the RED

LED on.

Note Receiver contains some electronic components of high-precision. Be careful to avoid strong vibration

and high temperature.

When all the above steps are complete, please turn off the transmitter and repower on to test if the receiver is

correctly connected with it.

2. Transmitter Antenna Installment

The transmitter antenna is adjustable so please make sure that the antenna never points directly

at the model when flying as this may possibly decrease the receiver signal.

Keep the antenna perpendicular to the transmitter to optimize the receiver performance. It also

depends on how you hold the transmitter. But in most cases, adjusting the antenna with perpendicular

position to the transmitter surface will achieve the best result. Please adjust the transmitter antenna

according to the way you hold the transmitter.

Never grip the antenna when flying as this degrades= effective control range..

1.3 RADIO BASIC SETTING

1.3.1 Basic setting of the transmitter

1. Display language: can be selected the display language of the function name, etc. in each function menu.

The screen reads "LANGUAGE". Change this to the desired language.

2. Stick Mode: The screen reads "STK-MODE". Change this to the correct mode. Note that this will NOT

change the throttle and elevator ratchets, etc. Those are mechanical changes that must be done by a

1.3.2 Model type

Under basic menu, use DIAL to select MODEL TYPE and enter by pressing PUSH. There are 6 different type

included in the system, HELICOPTER, AEROBASIC, GLID(1A+1F), GLID(2A+1F), GLID(2A+2F), and

MULTIROTOR, after model type is selected, press and hold PUSH for 1 second, when the word “are you sure

to change” displayed, model type is changed.

1.3.3 Binding

Each transmitter has an individually assigned, unique ID code. Receiver should bind to transmitter before

starting operation. Once binding is complete, the ID code will be stored in the receiver and no further binding

is necessary unless the receiver is used with another transmitter. When you purchase a new R9DS, this

procedure is necessary; otherwise the receiver will not work.

1. Put the transmitter and the receiver close to each other about 50 centimeters.

2. Power on AT9S Pro and receiver R9DS. The RED LED will be on.

3. Turn on AT9S Pro and it will automatically bind with the closest receiver.

4. There is a black binding button (ID SET) on the side of receiver. Press the button for more than 1 second

and release, the RED (by default, could be Purple for SBUS&PWM signal output) LED will flash, meaning

binding process is ongoing.

5. When the LED stops flashing and is always on , binding is complete.

6. Make sure servos connected with the receiver can be operated by the transmitter.

1.3.4 Two signal working modes of R9DS:

There are two signal working modes, PWM and SBUS&PWM signal output. Short press ID SET twice within

1s, the working mode will change.

The RED led indicates the PWM output and BLUE/PURPLE led indicates

SBUS signal.

signal and original CH2 to CH6 output CH6 to CH10 PWM signal at the same time.

1.3.5 Transmitter Displays & Buttons

When you first turn on your transmitter, a confirmation double

beep sounds, and the screen shown below appears. Before

flying, or even starting the engine, be sure that the model type

and name appearing on the display matches the model that

you are about to fly! If you are in the wrong model memory,

servos may be reversed, and travels and trims will be wrong,

leading to an immediate crash.

Warning and error display

When the transmitter is powered on, warning or error may happen by the following probability

1. Battery low voltage alarming

Lithium battery 2S-4S can fit for the transmitter, warning voltage can be

self-set according to different battery.

Setting step: power on the transmitter, press and hold MODE one

second to enter basic menu, and press PUSH to enter PARAMETER.

Choose TX ALARM by DIAL and PUSH to change relative data.

Suggested min voltage is not less than 7.4V.

When the transmitter voltage is less than the setting voltage, it will beep

till the transmitter is powered off. Most important thing is to land your

model plane when the transmitter alarms.

2. Mixing alarm

When the transmitter alarms mixing, it means at least one mixed switch

is active. And when it is inactive, warning will stop then. When the

transmitter is powered on, in different model type, mixing switch is

shown as below:

ACRO: throttle cut, idle down, snap roll, air brake

GLID: butterfly, condition

HELI: throttle cut, throttle lock, speed up

If the warning continues even the related switch is set OFF, probably it is

because some programs mixed by one switch and status OFF reversed. Now you need to set mixing alarm

again by DIAL.

PART 2. BASIC FUNCTION OF AIRPLANE

Pay attention that the (BASIC) menu is suitable for all type models (airplane, helicopter, glider, MULTIROTOR,

cars and boats). The motor cut will be introduced in Glider (Basic) Menu, except Idle down &Throttle cut.

Helicopter Basic Menu include some extra function (swashplate tilting, throttle and pitch curves and the tail

2.3.3 End Point of servo travel adjustment (END POINT, also called EPA)

The most flexible version of travel adjustment is available. It independently

adjusts each end of each individual servo’s travel, rather than one setting for

the servo affecting both directions. Again, for CCPM helicopters, be sure to

see SWASH AFR prior to adjusting end points.

Adjustability:

• Can set each direction independently.

• Ranges from 0% (no servo movement at all) to 140%. At a 100% setting,

the

Throw of the servo is approximately 40°for channels 1-4 and approximately 55°for channels 5-8.

• Reducing the percentage settings reduces the total servo throw in that direction.

Examples:

• Adjust the throttle high end to avoid binding at the carburetor, and low end to allow for proper carburetor

closure.

• END POINT may be adjusted to 0 to keep a servo from moving one direction, such as flaps not intended to

Radiolink Electronic Ltd

www.radiolink.com

also operate as spoilers.

• Retract servos are not proportional. Changing END POINT will not adjust the servo.

END POINT adjusts only the individual servo. It will have no effect on any other servo that is operated in

conjunction with this servo via mix or preset programming such as FLAPERON, AILEVATOR, etc. This is so that

each individual servo can be carefully fine-turn to avoid binding and other conflicts. To adjust the total travel of a

function such as FLAPERON, make the adjustments in that function's controls. For CCPM helicopters, adjust

the total travel of the function, such as collective pitch, in SWASH AFR. Adjust the linkage or the END POINT? It

is nearly always best to adjust your linkages to get as close as possible prior to utilizing END POINT. The higher

the END POINT setting, the better position accuracy and the more servo power available at nearly any position

(except if using digital servos). Higher END POINT values also mean longer travel time to reach the desired

position, as you are utilizing more of the servo's total travel. (For example, using 50% END POINT would give

you only half the steps of servo travel, meaning every click of trim has twice the effect and the servo gets there

in half the time). End point (and moving the linkage) = torque, accuracy, but transit time to get there.

• END POINT (instead of adjusting linkages) = travel time, but torque, accuracy.

Engine idle management: IDLE-DOWN and THR-CUT: functions which work with the digital THROTTLE TRIM

to provide a simple, consistent means of engine operation. No more fussing with getting trim in just the right

spot for landings or take offs! For additional engine adjustments, see THROTTLE-NEEDLE and THROTTLE

DELAY.

2.3.4 Trim

TRIM submenu: resets and adjust effectiveness of digital trims.

The AT9 has digital trims which are different from conventional

mechanical trim sliders. Each TRIM LEVER is actually a

two-direction switch. Each time the TRIM LEVER is pressed, the

trim is changed a selected amount. When you hold the TRIM

LEVER, the trim speed will increase. The current trim position is

graphically displayed on the start up screen. The TRIM submenu

includes two functions that are used to manage the trim options.

（1） Trim reset (RESET): Electronically centers the trims to their default values. Note that the

SUB-TRIM settings and the trim STEP rate are not reset by this command.

（2） Trim step (STEP): changes the rate at which the trim moves when the TRIM LEVER is activated.

It may be set from 1 to 40 units, depending on the characteristics of the MULTIROTOR. Most

ordinary MULTIROTOR do well at about 2 to 10 units. Generally larger trim steps are for models

with large control throws or for first flights to ensure sufficient trim to properly correct the model.

Smaller trim steps are later used to allow very fine adjustments in flight.

HELI models only: OFFSET is available in the idle ups. If OFFSET is inhibited, adjustment of the TRIM

LEVERS will adjust the trims for all flight conditions. If OFFSET is active, then moving the trims within any one

condition will affect only that condition.

2.3.5 SUB TRIM

SUB-TRIM: makes small changes or corrections to the neutral

position of each servo. Range is -120 to +120, with 0 setting, the

default, being no SUB-TRIM.

We recommend that you center the digital trims before making

SUB-TRIM changes, and that you try to keep all of the SUB-TRIM

values as small as possible. Otherwise, when the SUB-TRIM is of

large values, the servo's range of travel is restricted on one side.

The recommended procedure is as follows:

• Measure and record the desired surface position;

• Zero out both the trims (TRIM RESET menu) and the SUB-TRIM (this menu);

• Mount servo arms and linkages so that the control surface’s neutral is as correct as possible; and

• use a small amount of SUB-TRIM to make fine corrections.

2.3.6 Servo Reversing (REVERSE):

Changes the direction an individual servo responds to a CONTROL

STICK motion.

Caution ： Since channel 9 and 10 are switch only, its servo

REVERSE is in the AUX-CH control screen with its switch

assignment. Be sure to read the section on SWASH AFR before

reversing any servos.

2.3.7 Dual/triple rates and exponential (D/R,EXP)

Dual/Triple Rates: reduce/increase the servo travel by flipping a

switch, or (ACRO GLID) they can be engaged by any stick

position. Dual rates affect the control listed, such as aileron, not

just a single (ex: channel 1) servo. For example, adjusting aileron

dual rate will affect both aileron servos when using FLAPERON or

AIL-DIF, and both aileron and elevator servos’ travel when using

AILEVATOR or ELEVON or a CCPM helicopter.

Activation:

• Any SWITCH, A-H. If you choose a 3-position switch, then that dual rate instantly becomes a triple rate.

• The glider programming offers you the choice of

Condition. This option allows you to have a

separate rate for each of condition. (GLID)

• Stick position (ACRO GLID). (Ex: On rudder you

normally use only the center 3/4 of the stick

movement except for extreme maneuvers such as

snaps/spins/stalls. As long as your RUDDER

STICK does not exceed 90% (ie. stall turn), the

rudder goes to high rate's 90%, which is a MUCH

higher amount of travel than your low rate at 89%)

Radiolink Electronic Ltd

www.radiolink.com

Adjustability:

• Range: 0 - 140% (0 setting would deactivate the control completely.) Initial value=100%

• Adjustable for each direction (ACRO/ GLID)

(i.e. Up/down, left/right) (Ex: Most models fly upright without any elevator trim, but require some down

elevator when inverted just to maintain level flight. By increasing the down travel by the amount required to

hold the model inverted, the model now has equal travel available from level upright or level inverted.

Only if any stick is chosen by the item of "SW1", a switch can also be chosen by the item of "SW2." When

operated simultaneously, the switch operation has priority over the stick operation. (ACRO)

Exponential:

Change the response curve of the servos relative to the stick position to make fly more pleasant. You can

make the servo movement less or more sensitive around neutral for rudder, aileron, elevator, and throttle

(except HELI type use THROTTLE CURVE instead). (ACRO type throttle EXP and THROTTLE CURVE can

not be activated simultaneously). Many models require a large amount of travel to perform their best tricks.

However, without exponential, they are touchy around neutral, making them unpleasant to fly and making

small corrections very difficult. Additionally, by setting different exponentials for each rate, you can make the

effectiveness of small corrections similar in each rate, as in our example below:

The best way to understand exponential is to try it:

• Having made no changes yet in the D/R, EXP screen, move SWITCH D to DOWN (toward the AILERON

STICK).

• Move SWITCH D up. Hold the AILERON STICK at 1/4 sticks and moves SWITCH D down.

• Notice how much less travel there is.

• Go to 3/4 stick and repeat. Notice how the travel is much closer, if not identical.

Adjustability:

• More sensitive around neutral. (Positive exponential)

• Less sensitive around neutral. (Negative exponential)

• Adjustable for each direction. (ACRO/GLID)

For throttle, exponential is applied at the low end to help nitro and gasoline engines have a linear throttle

response, so that each 1/4 stick increases engine RPM 25% of the available range. (In most engines this

ranges from 5-60%)

Special note for helicopters: Helicopter model types have just a single rate for each switch position rather

than a rate for each side of the servo's travel per switch position. Additionally, setting the D/R, EXP for each

switch position requires cursor back to the No. setting and changing the switch position here. Just flipping the

switch does not affect the screen setting, allowing dual rates to be assigned with idle-up and other features on

certain switches, and does not require putting the model in that condition to make modifications.

Special note for conditions: The helicopter and glider programming offers you the choice of COND. This

option allows you to have a separate rate for each of the 3 controls automatically selected when changing

conditions, for a total of FIVE rates available. Simply change the switch choice to COND. and then:

(HELI) press the CURSOR LEVER to toggle through the 5 conditions while setting the rates.

(GLID) activate the corresponding condition to edit the rates.

NOTE: This normal rate has

no exponential so it has a

Very linear, normal feel.

This is slow roll rate has

positive exponential

(the opposite of what most

people normally uses),

which makes the servos

more responsive around

center. This makes the

servos feel the same around

center in the normal and low

rates, but still gives a very

slow roll rate at full stick.

3D rate (extreme aerobatics)

has a very high distance of

travel nearly twice that of

2.3.8 Throttle Cut

AEROBASIC

Throttle cut (THR-CUT) (ACRO0/HELI): provides an easy way to stop the

engine by flipping a switch (with THROTTLE STICK at idle). The movement

is largest at idle and disappears at high throttle to avoid accidental dead

sticks. In HELI, there is an additional setting.

The switch's location and direction must be chosen. It defaults to NULL to

avoid accidentally assigning it to a switch, which might result in an

unintentional dead stick in flight.

* Also LOGIC SW(Lsw1 to 3) may be assigned.

** Normally, a setting of 10-20% is sufficient. Viewing the carburetor barrel until it fully closes is adequate to

get an approximate setting; then test with engine running to confirm.

GLIDER

Provides an easy way to stop the engine by flipping a switch no matter where the air brake stick is. The

movement of servo will be -30%. Now you must select switch position and direction. Factory setting the

position is NULL to avoid an accident setting on a switch to cause glitches during flight.

Adjustability:

• Range: -30% to +30%. Movement of servo is 0%, air brake stick is on its min and -30% on the max.

• SWA-H and logic switch Ls1-3 is selectable

• All position is available for logic switch including NULL (usually MIX OFF), you can set MIX by different

position of a switch (UP & CEN, CEN & DN) and also NORM, REV.

HELICOPTER

This function is used to stop engine after flight is finished. You can set engine powered on/ off, without

shifting trim stick to power off and set again every time before flight. Throttle shut for helicopter includes THR

ON/ OFF (position above idle down). Before resetting throttle cut, throttle stick must keep below setting point

to avoid a sudden speeding up.

Notification: trigger point setting step: under the menu THR CUT, choose THRO by DIAL, and press

PUSH and move the throttle stick to trigger point, then press and hold PUSH one second to save. This

function only when the throttle stick moves below trigger point.

2.3.9 IDLE DOWN (ACRO only)

Lowers the engine idle for: set for sitting on the runway prior to take off,

stalls and spins, and landings. The normal idle setting is a little higher for

easier starts and safe flights with less risk of dead sticks.

Important note: The IDLE-DOWN function is not normally used when

starting the engine, and its accidental operation may keep your engine

from starting. The AT9 warns that IDLE-DOWN is on when the transmitter

is turned on. Be sure to turn off the function, or override the warning by pressing CURSOR lever if you

intended the function to be on.

This may be assigned to any switch/position. Some modelers accidentally assign IDLE-DOWN to one side of

a switch and THR-CUT to the other. There is no "normal" setting to start the engine. By default IDLE-DOWN is

get to SWITCH C center and down. This works well with THR-CUT also on SWITCH C down. The SWITCH C

up is normal flight/starting, center for slower maneuvers/landing, and down to cut the engine. If you assign

IDLE-DOWN or THR-CUT to the spring-loaded TRAINER SWITCH H or F, then use the trainer function, you

may risk loss of throttle control or dead stick for your student.

allow the engine to “clean out” and idle reliably.

*Also LOGIC SW (Lsw1 to 3) may be assigned.

2.3.10 Fail Safe (F/S)

(loss of clean signal and low receiver battery) submenu (F/S): sets

responses in case of loss of signal or low Rx Battery.

Adjustability:

•Each channel may be set independently.

• The NOR (normal) setting holds the servo in its last commanded

position.

• The F/S (Failsafe) function moves each servo to a predetermined

position.

• NOTE: the setting of the throttle's F/S also applies to the Battery F/S.

• The F/S is used in certain competitions to spin the MULTIROTOR to the ground prior to flying away and

doing potential damage elsewhere. Conversely, may also be used to go to neutral on all servos, hopefully

keeping the plane flying as long as possible.

• Competition modelers often maintain the NOR function so that brief interference will not affect their model's

maneuver.

• Set the throttle channel so that the engine idles when there is interference (ACRO). This may give enough

time to fly away from and recover from the radio interference and minimize damage if crashed.

• For helicopters, NOR is typically the safest choice.

•We also recommend setting a gasoline engine's electronic kill switch to the OFF position in the F/S function

for safety reasons.

If you specify a F/S setting, the Failsafe data is automatically transmitted once each two minutes. (PCM)

When you choose the F/S mode, check that your settings are as desired by turning off the transmitter power

switch and verifying that the servos move to the settings that you chose. Be sure to wait at least two minutes

after changing the setting and turning on the receiver power before turning off the transmitter to confirm your

changes have been transmitted.

2.3.11 Auxiliary Channel Function (including channel 9-10 controls)

(AUX-CH): defines the relationship between the transmitter controls and the receiver output for channels 5-10.

Also, the CH9-10 POSI are used to change the CH9-10 servo direction.

Note that the CH9-10 functions are only visible in the AUX-CH screen and modulation mode must be PCM or

2.4G.

Adjustability:

• channels 5-8 may be assigned to any SWITCH (A-H), LOGIC SWITCH (Lsw1-Lsw3), slider [VR(D) and

VR(E)], or knob [VR(A-C)] (for example, moving flaps to a switch or slider), but not the primary control sticks

(use programmable mixes to do so);

• channel 9-10 may be assigned to any SWITCH (A-H), LOGIC SWITCH

(Lsw1-Lsw3) and the servo direction may be changed.

• multiple channels may be assigned to the same switch, slider or knob;

• channels set to "NULL" are only controlled by mixes. (Ex: utilizing 2

channels for 2 rudder servos. See mixes p. 68.)

• If GYRO SENSE, GOVERNOR, and THR-NEEDLE functions are

activated, AUX-CH settings of related channels become invalid automatically.

Related channels:

GYRO SENSE (ACRO): ch. 5, 7, or 8

GYRO SENSE (HELI): ch. 5

GOVERNOR (HELI): ch. 7, or ch. 7 and 8

THR-NEEDLE (ACRO HELI): ch. 8

Remember that if you assign primary control of a channel to a switch which you later use for other

functions (like dual/triple rates or airbrakes), every time you use that other function you will also be moving the

auxiliary channel.

2.3.13 TRAINER:

For training novice pilots with optional trainer cord connecting 2

transmitters. The instructor has several levels of control.

Adjustability:

• NORM: When the TRAINER SWITCH is ON, the channel set to this

mode can be controlled by the student. The set channel is controlled

according to any programming set at the student's transmitter.

• FUNC: When the TRAINER SWITCH is ON, the channel set to this

mode can be controlled by the student, controlled according to any

mixing set at the instructor's transmitter.

• MIX: When the TRAINER SWITCH is ON, the channel set to this mode can be controlled by both the

student and the instructor, controlled according to any mixing set at the instructor's transmitter. And the

student's mixing rate is adjustable. (Default 30%)

[Note] However, it becomes invalid even if it sets up the channel which is not in a student's transmitter. The

channel serves as operation by the instructor's transmitter automatically.

• OFF: The channel set to this mode cannot be controlled by the student even when the TRAINER SWITCH

is ON. The set channel is controlled by the instructor only, even when the TRAINER SWITCH is ON.

• SWITCH: controlled by spring-loaded SWITCH H only. Not assignable.

• Compatibility: The AT9S Pro may be master or student with any Radiolink transmitter compatible with the

cord. Simply plug the optional trainer cord (For AT9S Pro series, sold separately) into the trainer connection

on each transmitter, and follow the guidelines below.

EXAMPLES:

•When throttle/collective is set to FUNG, 5-channel helicopter practice is possible with a 4-channel

transmitter.

• Set up the model in a second transmitter, use NORM mode to quickly and safely check proper operation of

all functions, and then allow the student radio to fully fly the model.

• Using NORM mode, set lower throws, different exponentials, even different auxiliary channel settings on

the student radio (if it has these features).

• To ease the learning curve, elevator and aileron may be set to the NORM or FUNC mode, with the other

channels set to OFF and controlled by the instructor.

NOTE:

• NEVER turn on the student transmitter power.

•ALWAYS set the student transmitter modulation mode to PPM.

• BE SURE that the student and instructor transmitters have identical trim settings and control motions.

Verify by switching back and forth while moving the control sticks.

• FULLY extend the instructor's antenna. Collapse the student's antenna. (Except 2.4GHz)

• When the TRAINER function is active, the snap roll function is deactivated. Other functions, such as

IDLE-DOWN and THR-CUT, which have been assigned to the same switch, are not deactivated. Always

double check your function assignments prior to utilizing the TRAINER function.

•When you select a different model, the TRAINER function is deactivated in the current model for safety

reasons.

Part 3. ACRO ADVANCE MENU FUNCTIONS

3.1 AIRPLANE WING TYPES (ACRO/GLID):

There are 3 basic wing types in MULTIROTOR models:

• Simple. Model uses one aileron servo (or multiple servos on a Y-harness into a single receiver channel) and

has a tail. This is the default setup and requires no specialized wing programming.

• Twin Aileron Servos. Model uses 2 aileron servos and has a tail. See TWIN AILERON SERVOS.

• Tail-less models (flying wing). Model uses 2 wing servos working together to create both roll and pitch

control. See ELEVON.

Twin Aileron Servos (with a tail) (ACRO/GLID): Many current generation models use two aileron servos,

plugged into two aileron servos, plugged into two separate receiver channels. (If your model is a flying wing

without separate elevators, see ELEVON)

ADVANTAGE:

• Ability to adjust each servo's center and end points for perfectly matched travel.

• Redundancy, for example in case of a servo failure or mid-air collision.

• Ease of assembly and more torque per surface by not requiring torque rods for a single servo to drive 2

surfaces.

• Ease of assembly and more torque per surface by not requiring torque rods for a single servo to drive 2

surfaces.

• Having more up aileron travel than down travel for straighter rolls, aileron differential. (See glossary for

definition.)

• Set a negative percentage to reverse the operation of one of the servos.

Options:

• 5-channel receiver. Set up AILE-2 prior to continuing with FLAPERON or AIL-DIFF.

• FLAPERON:

•Uses CH6 for the second servo

• Allows flap action as well as aileron action from the ailerons.

• Provides FLAP-TRIM function to adjust the neutral point of the FLAPERON for level flight.

• Also allows aileron differential in its own programming (instead of activating AIL-DIFF).

• Uses CH7 for the 2nd servo (see AIL-2 use CH5)

• Leaves CH5 & CH6 free for flap operation, such as FLAPERON and flap action together, in AIRBRAKE.

• Allows for more up aileron travel than down for straighter rolls. You will need to choose which of FLAPERON

or AIL-DIFF is better for your model's setup. If you need the ailerons to also operate as flaps, you most likely

want to use FLAPRON. If your model has 2 aileron servos and flaps, then AIL-DIFF is probably the easiest

choice.

NOTE: Only one of the three wing-type functions (FLAPERON, AIL-DIFF, and ELEVON) can be used at a

time. All three functions cannot be activated simultaneously. To activate a different wing type, the first must be

deactivated.

3.2

TWIN AILERON SERVOS (5-channel receiver, AILE-2 , ACRO/GLID)

AILE-2 allows FLAPERON and AIL-DIFF with a 5-channel receiver. AILE-2 only tells the radio that you are

using CH5 and CH6 (FLAPERON), or CH5 and CH7 (AILDIFF), not CH6 or CH7, as the second servo in

FLAPERON or AILE-DIFF. You still must activate and set up the FLAPERON/AILE-DIFF function.

Note that selecting CH6&5 or CH7&5 does NOT free up CH6 or CH7 to be used for other functions when

using a receiver with more than 5 channels. Both 5 and 6 (FLAPERON/AILE-DIFF) are dedicated to the

Radiolink Electronic Ltd

www.radiolink.com

FLAPERON or AILE-DIFF programming. [This is beneficial with four aileron servos that need to have their

end points or sub-trims set separately. CH1, CH5 and CH6 are already fully set up to operate as ailerons. Mix

the CH7 or CH8 (the second aileron servo on the other side) into ailerons to function properly.

There are 4 basic tail types in MULTIROTOR models:

• Simple. Model uses one elevator servo and one rudder servo (or multiple servos on a Y-harness). This is the

default.

• Dual Elevator servos. Model uses 2 elevator servos.

• Tail-less models. Model uses 2 wing servos together to create roll and pitch control. See ELEVON (ACRO/

GLID 1A+1F).

• V-TAIL. Model uses 2 surfaces, at an angle, together to create yaw and pitch control. see V-TAIL (ACRO/

GLID).

Note

: Only one of the three tail-type functions (AILEVATOR, V-TAIL, and ELEVON) can be used at a time.

The radio provides a warming and will not allow the activation of another tail type until the first is deactivated.

An error message of OTHER WING MIXING IS ON will display.

Using ELEVON (ACRO/GLID 1A+1F): it is used with delta wings, flying wings, and other tailless

MULTIROTOR that combine aileron and elevator functions, using two servos, each one on the ELEVON. The

aileron/elevator responses of each servo can be adjusted independently. This is also popular for ground

model use, such as tanks, which drive two motors together for forward, and one motor forward/ one backward

for turning.

3.3 ACRO ADVANCE FUNCTION MENU

Mixes are special programs within the radio that command one or more channels to act together with input

from only one source, such as a stick, slider or knob.

There are a variety of types of mixes:

TYPE:

• Linear: Most mixes are linear. A 100% linear mix tells the slave servo to do exactly what the master servo is

doing, using 100% of the slave channel’s range to do so. An example is FLAPERON, when aileron stick is

moved, the flap servo is told to move exactly the same amount. A 50% linear mix would tell the slave servo,

for example, to move to 50% of its range when the master’s control is moved 100%.

• Offset: An OFFSET mix is a special type of linear mix. When the mix is turned on (usually a flip of a switch),

the slave servo is moved a set percent of its range. An example of this is AIRBRAKE, moving flaps,

FLAPERON, and elevator all to a set position at the flip of a switch.

• Curve: Curve mixes are mostly used in helicopters, but may also be used in airplanes and gliders. An

example is THROTTLE-NEEDLE mixing, where the in-flight needle’s servo is moved, changing the mixture,

as the throttle servo is moved.

• Delay: Delay mixes are part of a few very special functions that make the servo move to its desired range

more slowly.

THROTTLE DELAY (simulates turbine engines) and the elevator delays in AIRBRAKE are two examples of

Radiolink Electronic Ltd

www.radiolink.com

this. DELAY in HELI is another example that slows the servo movement to the trim settings for the other

conditions.

Essentially every feature in the radio's programming is really a mix, with all assignments/programming set up

and ready to use. Additionally, the AT9 ACRO and GLID programs both provide 4 linear and 4 curve

fully-programmable mixes ( HELI provides 4 linear and 2 curve) that allow you to set up special mixes to

resolve flight difficulties, activate additional functions, etc.

Let’s look quickly at a few examples that are features we’ve already covered. This may help to clarify the mix

types and the importance of mixes:

Additional example:

• Exponential is a preprogrammed curve mix that makes the servos’ response more (+) or less (-) sensitive

around center stick (works in conjunction with dual rate, a linear mix that adjusts the total range). see

D/R,EXP,

• IDLE-DOWN and THR-CUT are two OFFSET pre-programmed mixes. These tell the throttle servo, when

below a certain point, to move toward idle an additional set percentage to help close the carburetor.

• ELEV-TO-FLAP mixing is a pre-programmed linear mix to move the flaps proportionally to elevator control,

helping the model loop even tighter than it can on elevator alone.

• THROTTLE-NEEDLE mixing is a curve mix (like PROG.MIX 5 to 8) for proper in-flight needle setup.

• THROTTLE DELAY mixing is a pre-programmed delay mix that slows down the response of the CH3 servo.

Next, we'll get an in-depth look at some pre-programmed mixes (mixes whose channels are predefined for

simplicity) we’ve not covered yet, and last, look at the fully-programmable mix types.

3.3.1 Program MIX

AT9S Pro contains four separate linear programmable mixes. (Note that mixer #5-8’s mixing RATE are set

with a 5-point curve. HELI has mixer #5-6's mixing. See CURVE MIXES

There are a variety of reasons you might want to use these mixes. A few are listed here. All of the adjustable

parameters are listed below, but don’t let them scare you. For your first few times experimenting with mixes,

just turn on the default mixes, adjust them how you think they need to be, then use the servo screen to check

and see if you were correct. As with all functions, a sample

setup follows, step by step, to assist you.

Sample reasons to use linear programmable mixes:

• To correct bad tendencies of the MULTIROTOR (such as rolling in response to rudder input).

• To operate 2 or more servos for a single axis (such as two rudder servos).

• To automatically correct for a particular action (such as lowering elevator when flaps are lowered).

• To operate a second channel in response to movement in a first channel (such as increasing the amount of

smoke oil in response to more throttle application, but only when the smoke switch is active).

• To turn off response of a primary control in certain circumstances (such as simulating one engine flaming

-out on a twin, or throttle-assisted rudder turns, also with a twin).

Adjustability:

• Defaults: The 4 programmable mixes default to the most frequently used mixes for simplicity. If you want to

use one of these mixes, simply select that mix number so that the master and slave servos are already

selected for you.

• PROG.MIX1 aileron-to-rudder for coordinated turns

• PROG.MIX2 elevator-to-flap for tighter loops (HELI mixes default to ELEV-to-pitch.)

• PROG.MIX3 flap-to-elevator to compensate pitching with flaps (HELI mixes default to pitch-to-ELEV)

• PROG.MIX4 throttle-to-rudder ground handling compensation

•Channels available to mix: All four mixes may use any combination of CH1-8. (CH9-10 is not proportional

and cannot be mixed.) Offset and dials may also be set to the master channels.

•Master: the controlling channel, the channel whose movement is followed by the slave channel.

•Another channel: Most mixes follow a control channel. (Ex: rudder-to-ailerons, 25%, no switch, corrects roll

coupling.)

•Slave: the controlled channel. The channel is moved automatically in response to the movement of the

•Link: Link this programmable mix with other mixes.

Ex: PMIX FLAP-ELEVATOR mixing to correct for ballooning when flaps are lowered, but model has a V-tail.

Without LINK, this mix only moves CH2 elevator when flap is commanded, resulting in a dangerous

combination of yaw and roll. With LINK ON, mixing is applied to both CH2 and CH4.

• SWITCH: Any of the positions of any of the 8 switches may be used to activate a mix. Up&Cntr, Cntr&Dn

options allow the mix to be ON in 2 of the 3 positions of a 3-position SWITCH.

• NULL: No SWITCH can turn this mix OFF. This mix is active at all times.

• LOGIC SW (Lsw1 to 3) may be assigned.

• STK-THR: Turn on/off by THROTTLE STICK movement. Trigger point/direction are selectable. Ex:

OFST-to-(gear doors) mix to open gear doors at idle, which is only active if throttle is below half.

Other samples:

• RUD-ELEV (ACRO GLID) mix: Compensate for pitching up or down when rudder is applied.

• AIL-RUD mix (ACRO): Coordinate turns by applying rudder automatically with aileron input. All model types.

• ELEV-PIT (HELI) mix: Compensate for the loss of lift of tilting the model

3.3.2 Curve Programmable Mixes (PROG.MIX5-8)(HELI: PROG.MIX5-6 ):

AT9S Pro’s ACRO/GLID programs contain four separate curve programmable mixes. HELI contains two.

There are a variety of reasons you might want curve mixes. Usually a linear mix doesn't fit your needs along

the whole range. One pre-programmed curve mix is the THROTTLE-NEEDLE function. This curve is

adjustable at 5 points, allowing you to adjust the motor’s tuning at 5 points along its RPM range.

One programmable curve mix defaults to RUDDER-AILERON. A linear mix that keeps the model from rolling

in knife-edge is probably too much aileron when rudder is applied in level flight. Create a curve mix and set all

5 points to match the linear mix. Inhibit the linear mix, and then adjust the curve to get the right response all

along the rudder channel’s travel.

Adjustability:

• ACRO/GLID Defaults: The 4 programmable curves mixes default to the most frequent choices, but can be

set to any channel.

• PROG.MIX5 rudder-to-aileron for roll coupling compensation (GLID mixes default to aileron-to-ELEV.)

• PROG.MIX6 rudder-to-aileron for roll coupling compensation (GLID mixes default to aileron-to-ELEV.)

• PROG.MIX7 rudder-to-elevator for pitch coupling compensation (GLID mixes default to

elevator-to-airbrake.)

• PROG.MIX8 rudder-to-elevator for pitch coupling compensation (GLID mixes default to

elevator-to-airbrake.)

• HELI Defaults:

• PROG.MIX5 aileron-to-elevator for coordinated turns

• PROG.MIX6 aileron-to-elevator for coordinated turns

• Master: The controlling channel can only be a channel. Cannot OFFSET or dial.

• Trim: not available in curve mixes.

• Offset: not available in curve mixes.

3.3.3 FLAPERON (ACRO/GLID 1A+1F ):

ACRO GLID

The FLAPERON mixing function uses one servo on each of the two ailerons, and uses them for both aileron

and flap function. For flap effect, the ailerons raise/lower simultaneously. Of course, aileron function (moving

in opposite directions) is also performed.

Note: When changing the polarity of a rate, "change rate dir?" is displayed for a check. Please set up after

pressing DIAL for 1 second and canceling an alarm display. (GLID only)

Once FLAPERON is activated, any time you program CH6 or "flap" (i.e. ELEVATOR mixing), the radio

commands both servos to operate as flaps. The amount of travel available as flaps is independently

adjustable in FLAPERON. A trimming feature is also available (see FLAP-TRIM) to adjust both neutral

positions together for straight-and-level flight or slight increases/decreases of the flap angle. END POINT and

SUB-TRIM both still adjust each servo individually.

Adjustability:

• Each aileron servo up travel can be set separate from its down travel, creating aileron differential. (See

example).

• Each aileron servo's travel when actuated as a flap is separately adjustable.

• AILE-2 can be utilized to use a 5-channel receiver and still have FLAPERON. NOTE: The AILE-2 function

only commands the channel 5 servo to operate with the aileron servo as ailerons, and to obey the primary flap

control (travel adjusted in FLAP-TRIM.) It does not provide full flap mix capability as when using a 6+ channel

receiver and channel 6.

Radiolink Electronic Ltd

www.radiolink.com

• The separate FLAPERON settings for each condition can be set. (GLID)

Note: Activating FLAPERON only makes the ailerons work as ailerons and tells the radio how far you want

them to move as flaps. If you then activate other programming that moves them as flaps.

FLAP-TRIM is the flap-trimming feature that allows the flaps to move in reaction to the channel 6 control. It is

meant only for trimming the flaps' center but can also be used as full flap control.

ELEVATOR-FLAP would add elevator mixing into the flap movement from the flap dial after FLAP-TRIM is

activated.

3.3.4 FLAP-TRIM

Using FLAP-TRIM to adjust FLAPERON (ACRO/GLID)

ACRO GLID

FLAP-TRIM assigns the primary FLAPERON control [defaults to VR(A)] to allow trimming in flight of the flap

action of FLAPERON.

Note: Even if FLAP-TRIM is made active with AIL-DIFF, it will not have any effect. The ONLY function that

allows control of the ailerons as flaps in the AIL-DIFF configuration is AIRBRAKE. Most modelers use

AIRBRAKE, or programmable mixes, to move the flaps to a specified position via movement of a switch.

FLAP-TRIM may also be used as the primary flap control in flight. By doing so, you can assign CH6 to a

3-position switch, with a "SPOILERON", neutral, and "FLAPERON" position, and even adjust the percentage

3.3.5 AILE DIFF (ACRO/ GLID 2A+1F/ GLID 2A+2F)

ACRO GLID (2A+1F)/GLID (2A+2F)

Aileron differential is primarily used on 3 or 4-servo wings, with one servo operating inboard flap on CH6 or

CH5 & CH6, and AILE-DIFF controlling proper aileron operation of 2 aileron servos, plugged into CH1 and

CH7. The ailerons can not be moved like flaps when using AILE-DIFF, except if using AIRBRAKE. (Note that

even if you make FLAP-TRIM active while using AILE-DIFF, it will not have any effect. ONLY AIRBRAKE

controls the ailerons as flaps in the AILE-DIFF configuration.)

Note: When changing the polarity of a rate in camber-flap, "change rate dir?" is displayed for a check.

3.3.6 Air Break (ACRO/ GLID)

ACRO GLID

Like FLAPERON and AILEVATOR, AIRBRAKE is one function that is really made up of a series of

pre-programmed mixes all done for you within the radio. AIRBRAKE (often called "crow" or BUTTERFLY -

see GLID, p. 62 for details) simultaneously moves the flap (if installed), twin ailerons (if installed) and elevator,

and is usually used to make steep descents or to limit increases in airspeed in dives.

This function is often used even on models without flaps as an easy way to use the FLAPERON and

FLAP-ELEVATOR mixing together.

Adjustability:

• Activation: be proportional by moving the THROTTLE STICK, or set positions by flipping the assigned

switch.

• Switch: Mix SWITCH is selectable.

• Also LOGIC SW (Lsw1 to 3) may be assigned.

• Linear(Inversely proportional to THROTTLE STICK): Provides a proportional increase in amount of

AIRBRAKE action as THROTTLE STICK is lowered and assigned switch is on. It provides gradually more

AIRBRAKE as you slow the engine. Includes selectable stick position where AIRBRAKE begins, gradually

increasing to the same setting as the THROTTLE STICK is lowered. If you would like to have the airbrake be

directly proportional to throttle stick, you will

need to reverse the THR-REV function. Note that this changes the throttle stick direction for all models.

• Offset: Provide AIRBRAKE response immediately upon switch movement, going to a pre-set travel on each

active channel without any means of in-flight adjustment.

• During Airbrake operation, the elevator travel is displayed on the elevator trim display in the Startup screen.

•Delayed reaction: You can suppress sudden changes in your model's attitude when

AIRBRAKE BUTTERFLY is activated by setting the delay (delay-ELEV) item, to slow down the elevator

response, allowing the flaps/ailerons/elevator to all reach their desired end point together. A setting of 100%

slows the servo to take approximately one second to travel the prescribed distance. (GLID: B.FLY-ELEV

function)

• Adjustable in flight (ACRO): Using the aileron (when AILE-DIFF or FLAPERON is activated) and elevator

trim lever in flight can be set to adjust the aileron and elevator settings in your airbrake rather than adjusting

the model's actual aileron and elevator trim. This allows easy adjustment for any ballooning while in flight.

When the airbrake switch is moved to off the trim is again adjusting the normal elevator trim.

• Channels controlled: Elevator, twin ailerons and flap may be set independently in AIRBRAKE, including set

to 0 to have no effect.

• If FLAPERON is active, the travel of the ailerons can be independently adjusted for the servos plugged into

CH1 and CH6. The flap choice has no effect on the FLAPERON.

• If AIL-DIFF is active, then CH1 and CH7 may be independently adjusted.

• Normally both ailerons are raised equally in AIRBRAKE, and the elevator motion is set to maintain trim when

Radiolink Electronic Ltd

www.radiolink.com

the ailerons rise. Different amounts may be set for each aileron to correct for torque reactions and other

unique characteristics of the model.

Be sure you understand what dropping ailerons will do when in AIRBRAKE BUTTERFLY. Along with

creating an enormous amount of drag (desirable for spot landings), this also creates "wash-in", a higher angle

of attack where the ailerons are, and encourages tip stalling.

If you are using this for aerobatic performance and not "sudden stops", consider raising the ailerons and

dropping the flaps instead as shown in the diagram above.

3.3.8 Dual Elevator Servos (with a rudder) (AILEVATOR) (ACRO):

Many models use two elevator servos, plugged in separate receiver

channels. (Flying wings without a separate aileron control use ELEVON.

V-shaped tail models use V-TAIL,

ADVANTAGE:

•Ability to adjust each servo's center and end points for perfectly matched

travel.

• Ease of assembly, not requiring torque rods for a single servo to drive 2

surfaces.

• Elevators acting also as ailerons for extreme stunt flying or more realistic jet flying (optional).

• Redundancy, for example in case of a servo failure or mid-air collision.

Adjustability:

• CH2 and CH8 only. (With programmable mixing, could utilize CH5 as the 2nd elevator servo.

THROTTLE-NEEDLE uses CH8 and cannot be active simultaneously).

• Direction of each servo's travel may be reversed in REVERSE or the set percentages may be reversed here.

• Elevator travels independently adjustable (both directions and percent).

•Optional action as ailerons (defaults to 50% response). This response cannot be activated/ deactivated in

flight. Setting AIL1 and 2 to 0 disables this feature.

Note: if you want this, but on/off with a switch, set AIL1 and 2 to 0 here, and use 2 mixes. AIL-to-AUX2

(link/trim off, assign a switch), get aileron action from the elevator servos when the assigned switch is on.

The AILEVATOR mixing function uses one servo on each of the two elevators, and combines the elevator

function with the aileron function (unless aileron travel is set to 0). For aileron effect, the elevators are raised

and lowered opposite of one another in conjunction with the ailerons.’

Once AILEVATOR is activated, unless you zero out the aileron figures (see below), any time you move your

ailerons or any programming moves your ailerons (i.e. RUDDER-AILERON mixing), the radio automatically

commands both elevator servos to also operate as ailerons. To deactivate this action, simply set the 2 aileron

travel settings to 0 in the AILEVATOR function. This way the elevators will work only as elevators.

3.3.9 Snap Rolls (ACRO)

This function allows you to execute snap rolls by flipping a switch,

providing the same input every time. It also removes the need to

change dual rates on the 3 channels prior to performing a snap, as

SNAP-ROLL always takes the servos to the same position,

regardless of dual rates, inputs held during the snap, etc.

Note: Every MULTIROTOR snaps differently due to its C.G.,

control throws, moments, etc. Some models snap without aileron;

others snap on elevator alone. Most models snap most precisely

with a combination of all 3 surfaces. Additionally, rate of speed and acceleration when using the snap switch

will affect how the model snaps. For information using gyros with airplanes for cleaner precision maneuvers,

such as snaps and spins without over rotation.

Adjustability:

• Travel: Adjust the amount of elevator, aileron and rudder travel automatically applied.

• Range: -120 to +120 on all 3 channels. Default is 100% of range of all 3 channels.

• Directions: Up to 4 separate snaps is fully adjustable regarding travels and direction on each of the 3

channels.

Note: for simplicity, the radio refers to snaps that use “UP” or positive elevator as “U” or “UP” snaps. This is

more commonly referred to as a positive or inside snap. “D” or “DOWN” snaps are more commonly referred to

as negative or outside snaps.

• R/U = Right positive R/D = Right negative L/U = Left positive L/D = Left negative snap roll.

• Assignment of the 2 switches (DIR-SW1/2) to change snap directions is fully adjustable and optional. If you

wish to have only one snap, leave the switches as NULL. (If assigned, SW1=up/down, SW2=left/right)

• Safety Switch (SAFE-MOD): a safety may be set up on your landing gear SWITCH, preventing accidental

Radiolink Electronic Ltd

www.radiolink.com

snap rolls while the landing gear is down. The safety switch is turned on and off with the landing gear

SWITCH.

• ON: the safety mechanism is activated when the landing gear SWITCH is in the same position as at the time

this feature is changed to ON. Snap rolls will not be commanded even if the snap roll SWITCH is turned on

with the gear SWITCH in this position. When the landing gear SWITCH is moved to the opposite position,

snap rolls may be commanded.

• OFF: Activate the safety mechanism in the opposite position from the ON function.

3.3.10 V-Tail (ACRO/ GLID)

V-TAIL mixing is used with v-tail MULTIROTOR so that both elevator and rudder

functions are combined for the two tail surfaces. Both elevator and rudder travel

can be adjusted independently on each surface.

Note: NOTE: If V-TAIL is active, you cannot activate ELEVON or AILEVATOR

functions. If one of these functions is active, an error message will be displayed

and you must deactivate the last function prior to activating ELEVON.

Note: Be sure to move the elevator and rudder sticks regularly while

checking the servo motions. If a large value of travel is specified, when the sticks are moved at the same time,

Radiolink Electronic Ltd

the controls may bind or run out of travel. Decrease the travel until no binding occurs.

Adjustability:

• Requires use of CH2 and CH4.

• Independently adjustable travels allow for differences in servo travels.

• Rudder differential is not available. (To create rudder differential, set RUD1 and 2 to 0, then use two

programmable mixes, RUD-ELE and RUD-RUD, setting different percents for up and down. These are your

new rudder travels. Trim and link off, switch assignment null so you can’t accidentally turn off rudder.

3.3.11 ELEVON

Adjustability:

• Requires use of CH1 and CH2.

• Independently adjustable aileron travel allows aileron differential.

• Independently adjustable elevator travel allows for differences in up vs.

down travel.

• The separate ELEVON settings for each condition can be set. (GLID

3.3.12 Gyro Sense

The gyros have two operations modes: GY mode and STD mode.

•STD mode: This mode performs general proportional control operation.

For instance, it controls the gyro so that changes are countered when the

attitude of the MULTIROTOR is changed by cross-wind, etc.

•GY mode: This mode performs both proportional and integrated control

operation. The difference between Normal mode and GY mode operation is

Radiolink Electronic Ltd

www.radiolink.com

that where as the Normal mode only counters changes in attitude, the GY mode returns to the original

controlled variable simultaneously with countering changes in attitude. For example, during knife edge flying,

aileron and elevator meeting rudder is normally necessary, but in the GY mode, meeting rudder is performed

automatically by the gyro.

Adjustability:

• Plug the gyro's sensitivity adjustment to channel 5, 7, or 8 of the receiver. (Selectable)

• Full switch assignable (SWITCH A-H)

• Each rate setting may be set from 0 to NOR100% or AVC100% gain. NOR: GY mode gain. AVC: STD mode

gain

• Larger percentages indicate more gain, or gyro responsiveness.

• MIX-1,2: Two surfaces' sensitivity can be adjusted independently.

GYRO GAIN Adjustability:

• When the servo hunts, the gyro gain is too high. Lower the gain until the hunting stops.

• The gyro will display best performance at a gain just before hunting occurs. Perform adjusting by flying the

MULTIROTOR repeatedly.

Precaution:

• When taking off and landing, always switch to the Normal mode. Taking off and landing in the GY mode is

dangerous.

•We recommend that you use the rudder control gyro in the Normal mode. In the GY mode, rudder operation

is necessary when turning because the weather vane effect is lost. Use the gyro in the Normal mode unless

you are an expert in rudder operation.

• And we recommend that you also set to off (0%) mode for safety as follows.

3.3.13 THR-DELAY (ACRO):

The THR-DELAY function is used to slow the response of the throttle servo

to simulate the slow response of a turbine engine. A 40% delay setting

corresponds to about a one-second delay, while a 100% delay takes about

eight seconds to respond. This function may also be used to create a

“slowed servo” on a channel other than throttle. This is accomplished by

plugging the desired servo (Ex: gear doors) into CH3 (THR), throttle into an

3.3.15 THROTTLE-NEEDLE mixing (ACRO/ HELI):

ACRO HELI

THROTTLE-NEEDLE is a pre-programmed mix that automatically moves an in-flight mixture servo (CH8) in

response to the THROTTLE STICK inputs for perfect engine turning at all throttle settings. This function is

particularly popular with contest pilots who fly in a large variety of locations, needing regular engine tuning

adjustments, and requiring perfect engine response at all times and in all maneuvers. Also popular to

minimize flooding at idle of inverted engine installations or installations with a high tank position. Not needed

for fuel injection engines, which do this automatically.

Adjustability:

• Five-point curve allows adjustment of engine mixture at varied throttle settings.

• The in-flight mixture servo must connect to receiver CH8.

• In-flight mixture servo may also be used as a second servo for tuning a twin.

• Throttle cut feature also moves the in flight needle servo.

• The CH8 knob adjusts the high throttle mixture (may be deactivated. see AUX-CH).

• Because both use CH8, this function cannot be used simultaneously with AILEVATOR.

• An acceleration (ACCE) function (ACRO only) helps the engine compensate for sudden, large amounts of

throttle input by making the mixture suddenly richer, then easing it back to the proper adjustment for that

throttle setting. This function requires some adjustment to best fit your engine and your flying style. Adjust

engine's response until no hesitation occurs on rapid throttle input.

• Separate curves are available (HELI only) for normal, idle-ups 1 and 2 combined, and idle-up 3. Immediately

below MIX the radio displays the curve you are editing; ex: >NORML; and then which condition is currently

active by your switches ex: (ID1/2). Note that you can edit the mix for a different condition without being in that

condition, to allow editing without having to shut off the helicopter’s engine every time. Be sure you are editing

the proper curve by checking the name after the > and not the one in parentheses.

4.2 SET GLID TYPE

TYPE: (GLID 1A+1F), GLID (2A+1F), GLID (2A+2F)

Before doing anything else to set up a glider or sailplane, first you must decide which MODEL TYPE best fits

your MULTIROTOR.

• GLID(1A+1F): The GLID (1A+1F) MODEL TYPE is intended for sailplanes with one or two aileron servos (or

none), and a single flap servo (or two connected with a y-connector). This TYPE is meant to be a very

simplistic version to set up a basic glider without a lot of added features. Additional flight condition is available.

• GLID (2A+1F): The GLID (2A+1F) MODEL TYPE is intended for sailplanes with dual aileron servos and a

single flap servo (or two connected with a y-connector). Additional flight conditions are available. These flight

conditions contain different offset trims and aileron differentials to make the sailplane perform certain

maneuvers more easily.

• GLID (2A+2F): The GLID (2A+2F) MODEL TYPE supports dual flap servos that can also act as ailerons,

creating full-span ailerons and flap. Additional flight conditions are available. These flight conditions contain

different offset trims and aileron differentials to make the sailplane perform certain maneuvers more easily.

4.3 GLID ADVANCE MENU

MIXES:

• Linear Programmable mixes (PROG.MIX1-4): Fully assignable programmable mixed with a linear response.

• Curved Programmable mixes (PROG.MIX5-8): Fully assignable programmable mixed with a curved

response.

• ELEV-FLAP pre-programmed mix creates elevator movement from the inboard flaps as well as elevators.

• BUTTERFLY: Often called crow, BUTTERFLY is the glider version of AIRBRAKE. (BUTTERFLY does not

have the option to activate it solely from a switch, and its activation switch. It always provides progressively

more BUTTERFLY as the CHANNEL 3 (THROTTLE) STICK is lowered, or raised if used THR-REV) See

AIRBRAKE.

• CAMBER-MIX AILE-FLAP: This pre-programmed mix is used to create full span flap/aileron action on a

glider with 4 wing servos. This changes the camber over the entire wing, which produces less drag than just

dropping the flaps by themselves.

Note: When you have ELEV-FLAP mixing also, the trailing edge droops with the elevators, increasing

pitch response.

• FLAPERON (GLID 1A+1F only): 2 aileron servos operate in opposite directions as ailerons and same

direction as flaps.

• CAMBER FLAP: Provides camber movement or trimming of flaps. For sailplanes, this function is also used

as wing camber. The amount depends on the model but usually a small amount (less then 10%) is preferred,

since too much camber produces excess drag. Don't use more than about 1/16" travel up or down for glider

camber. Some airfoils, such as the RG15, should be flown with NO reflex/camber. Be sure to consult your

model's manual for guidelines.

Note: even though you may make CAMBER FLAP active while using AILE-DIFF, it will not have any effect.

The ONLY function that allows control of the ailerons as flaps in the AILE-DIFF configuration is airbrake/

butterfly

• ELEVON: for flying wings

• V-TAIL: For models with 2 servos operate together to create roll and pitch control.

• AILEVATOR: Not available in GLID model types.

4.3.4 OFFSET (GLID 2A+2F):

Additional flight conditions are available specifically for sailplanes.

Radiolink Electronic Ltd

www.radiolink.com

These additional flight conditions contain different offset trims to

make the sailplane perform certain maneuvers more easily.

Aileron differential functions may be set to provide separate rates

per condition selected.

Prior to setting up OFFSET, you must active the conditions and

assign the switches in the CONDITION/FUNCTION.

Unnecessary fuselage motion is generated when there are

sudden changes in the servo position and variations in the

operating time between channels can be suppressed by using the

delay function.

Note: The same delay amount for elevator and rudder is recommended when using V-tail function.

The AT9 provides 5 additional setups along with the normal flight condition. (NORMAL,

START, SPEED, DISTANCE and LANDING) These offset trims have same setting abilities basically except

the switch and dial assignment. For an example of trim settings, please see the following:

Adjustability:

• Separate adjustments for each aileron, elevator, rudder and flap servo, for each condition.

• SWITCH G (AT10) or E (AT10) is programmed for NORMAL, START, and SPEED trims. SWITCH C is

programmed for DISTANCE and LANDING trims. These switch/position assignment is adjustable.

(CONDITION/FUNCTION)

• TRIM item (Digital trim operation mode):

NORM: normal trim operation mode.

MIX: offset rate trim operation mode while mixing is on.

• Optional assignable knob (CAMBER MIX) to allow trimming in flight of the aileron and flap action of each

flight condition.

• During OFFSET operation, the aileron and elevator travels are displayed on each trim display in the Startup

screen.

4.3.5 START DELAY (GLID 1A+1F only):

START DELAY automatically switch the offset trims (OFFSET) from the

START condition's trims to the normal condition’s trims after proceeding

the delay time (max.10sec.) which is set by the -DLY- item when

activating the START condition. (It is convenient for hand launch glider.)

This function adjusts the mixing rate of camber operation which

operates the wing camber (ailerons and flaps) in the negative and

positive directions. The aileron, flap, and elevator rates can also be

adjusted independently and attitude changes caused by camber

operation can be corrected.

Also the operation reference point of camber control can be offset.

• Switch: Mix SWITCH is selectable. A to H: SWITCH A to H. Also LOGIC SW (Lsw1 to 3) may be assigned.

NULL: always on.

• Inversely proportional to THROTTLE STICK: provides a proportional increase in amount of airbrake action

as THROTTLE STICK is lowered (when SWITCH A (assignable) is in down position). Includes selectable stick

position where airbrake begins. If you would like to have the airbrake be directly proportional to throttle stick,

you will need to reverse the THR-REV function.

Note:

this changes the throttle stick direction for all models.

INSTRUCTIONS:

• Elevator settings: (Adjustable in the B.FLY-ELE)

B.FLY-ELE works linking with BUTTERFLY function. Elevator rate is adjustable in a 3 point curve.

Point 1: PRESET point. (Fixed)

Point 2: MID point. Position and rate are adjustable.

Point 3: END point. Position and rate are adjustable.

• Delayed reaction: You can suppress sudden changes in your model's attitude when BUTTERFLY is

activated by setting the delay (DELAY) item, to slow down the elevator response, allowing the

flaps/ailerons/elevator to all reach their desired end point together. A setting of 100% slows the servo to take

approximately one second to travel the prescribed distance.

• Channels controlled: Twin ailerons, flap and spoiler may be set independently in BUTTERFLY, including set

to 0 to have no effect.

• Twin aileron servos: If AIL-DIFF function is inhibited, then AIL1 and AIL2 settings will have no effect. If

AIL-DIFF is active, then CH1 and CH7 may be independently adjusted.

• Normally both ailerons are raised equally in BUTTERFLY, and the elevator motion is set to maintain trim

when the ailerons rise. Different amounts may be set for each aileron to correct for torque reactions and other

unique characteristics of the model.

Be sure you understand what dropping ailerons will do when in BUTTERFLY. Along with creating an

enormous amount of drag (desirable for spot landings), this also creates "wash-in", a higher angle of attack

where the ailerons are, and encourages tip stalling. If you are using this for aerobatic performance and not

"sudden stops", consider raising the ailerons and dropping the flaps in stead as shown in the diagram above.

4.3.9 AILE/ RUDD MIX

You can select a pre-programmed mix which is used to mix the

rudders with aileron operation or the ailerons with rudder operation.

Aileron-to-rudder mix (AILE RUDD): automatically creates a

"coordinated turn".

Rudder -to-aileron mix (RUDD AILE): used to counteract undesirable

roll (roll coupling) that happens with rudder input, especially in

knife-edge.

Adjustability:

Part. 5 HELICOPTER MODEL FUNCTIONS

Please note that nearly all of the BASIC menu functions are the same for airplane (ACRO setup), sailplane

(GLID setups), and helicopter (HELI) setups. The features that are identical refer back to the ACRO chapter.

5.1 BASIC SETTING WITH HELICOPTER

This guideline is intended to help you set up a basic (H-1) heli, to get acquainted with the radio, to give you

a jump start on using your new radio, and to give you some ideas and direction on how to do even more with

this powerful system than you may have already considered.

Briefly, the typical helicopter's controls are as follows:

• Aileron: Changes cyclic lateral (roll). Roll the helicopter. Tilt the swash plate to the left or right CH1.

• Elevator: Changes cyclic pitch. Change the helicopter’s angle of attack (nose up or nose down). Tilt the

entire Swash plate fore and aft. CH2.

• Rudder: Change the angle of the tail rotor and yaw the helicopter left or right. CH4.

• Collective Pitch: Adjusts main rotor collective [angle of the paddles], changing the main blades’ pitch.

Increased collective pitch (with throttle) causes the helicopter to rise. Moves in conjunction with throttle on the

THROTTLE STICK. CH6.

• Throttle: Open/close carburetor. Move in conjunction with collective pitch on the THROTTLE STICK. CH3.

• REVO: mix that adds rudder in conjunction with pitch. This helps compensate for rotation of the helicopter

caused by the increased engine torque. (Never use REVO. mixing with a heading0hold/AVCS gyro; the gyro

already does this.)

Be sure to follow your model’s instructions for preflight checks, blade tracking, ect. Never assume a set of

blades are properly balanced and will track without checking.

Check receiver battery voltage! Always check voltage with a voltmeter prior to each and every engine

start.(Never assume being plugged in all night means your radio gear is ready to fly).Insufficient charge,

binding servo linkages ,and other problems can result in a dangerous crash with the possibility of injury to

yourself, others and property.

Confirm the swashplate is level at 0 travel. Adjust arms if needed.

Apply full collective and check that the swashplate remained level and there is no binding. Repeat for full

cyclic pitch and

roll. If not, adjust as needed to correct in

END POINT

Important note: prior to setting up throttle hold, idle-ups, offsets, etc, be sure to get your normal

condition operating properly.

Checking setup prior to going airborne: Check voltage! Then, with the assistance of an instructor, and

having completed all range checks, etc, gradually apply throttle until the helicopter becomes “light on the

skids.” Adjust trims as needed to correct for any roll, pitch, or yaw tendencies. If the tail “wags,” the gyro

gain is too high. Decrease gyro gain.

1. Periodically move the throttle stick to full and back down to ensure proper servo settings.

2. It is critical that dials A and C be centered when the pitch and throttle curves are setup.

5.2 HELI-SPECIFIC BASIC MENU FUNCTIONS

MODEL TYPE: This function of the PARAMETER submenu is used to select the type of model programming

Radiolink Electronic Ltd

www.radiolink.com

to be used. Before doing anything else to set up your model, first you must decide which MODEL TYPE best

fits your MULTIROTOR.

HELICOPTER SWASHPLATE TYPES:

The AT9 radios support 8 basic swash plate setups, including "single servo" (H-1-most helicopters use this

type) and 7 types of CCPM (cyclic and collective pitch mixing). A "single servo" swash plate uses one servo

for each axis: aileron, elevator (cyclic pitch), and collective pitch. CCPM helicopters utilize a combination of

servos working together to achieve the 3 axes of motion. There are 7 basic CCPM types, displayed below.

CCPM has several advantages, the most obvious of which is far less mechanical complexity to properly move

the swash plate of the helicopter. Additionally, several servos working in unison (ex: HR3, all 3 servos together

create elevator movement) dramatically increases the torque available as well as the precision and centering.

Please note that some helicopters are type HR3 or HN3, except off by 180 degrees. If your model 's swash

plate is off by 180 you will still use that swash plate type, but also use SWASH AFR to adjust the functions as

needed until it operates properly. Additionally, different angles of CCPM may also be created utilizing the fully

assignable programmable mixes.

Radio emits a repeating “beep” and shows progress on screen as the model type is being changed. Note that

if the power switch is turned off prior to completion, the model type will not be changed.

5.2.2 SWASH AFR (not in SWH1):

Except SWASH PLATE, function menu of helicopter is same as GLID/

ACRO. Please find the former instructions.

Swash plate function rate settings (SWASH AFR) reduce/increase/reverse

the rate (travel) of the aileron, elevator (except H-2) and collective pitch

functions, adjusting or reversing the motion of all servos involved in that

function, only when using that function. Since these types utilize multiple

servos together to create the controls, simply adjusting a servo's REVERSE

or END POINT would not properly correct the travel of any one control. Since H-1 uses one servo for each

function, there is no need for AFR in H-1.

Since aileron always uses no more than 2 servos, check it first. Either both operate properly (no change

needed), both operate backwards (reverse the whole function), or one servo operates backwards (reverse

that servo alone). Next check elevator. Remember, the aileron servo(s) operate correctly, so if elevator does

not, we should only have 2 choices left—the whole function needs to be reversed, or the servo(s) not shared

with aileron need to be reversed. If aileron and elevator are not working properly, the only thing that could be

wrong is the whole direction collective operates (reverse the whole function). In our example, HR3 is 180

degrees off from the swash plate of the Caliber. Therefore, it is very likely that several functions will not

operate properly. The collective pitch operation is backwards; but reversing all three servos would also

reverse the aileron and elevator operations. Changing the collective pitch rate, however, from +50% to -50%,

will reverse the collective pitch without affecting the aileron action.

5.3 HELI-SPECIFIC ADVANCE MENU FUNCTIONS

5.3.1 THR-CURVE and PIT-CURVE:

These 7-point curves are utilized to best match the blade collective pitch to the engine RPM for consistent

load on the engine. Curves are separately adjustable for normal, idle-up 1, idle-up 2, and idle-up 3. In addition,

a separate collective pitch curve is available for throttle hold. Sample curves are displayed in the appropriate

setup types (ex: normal flight condition) for clarity.

Suggested defaults:

• Normal: Collective pitch curve that results in points 1, 4 and 7 providing .4, +5, (+8 to +10)* degrees pitch. A

throttle curve setting of 0, 25, 36, 50, 62.5, 75, 100%.

• Idle-ups 1 & 2: Idle-ups 1 and 2 are typically the same except for the gyro settings, with one being

heading-hold/AVCS and the other being normal mode. The pitch curve will likely be similar to the normal

curve above.

• Idle-up 3: Collective pitch curves that result in points 1, 4 and 7 providing (.8 to .10), 0, (+8 to +10) degrees.

A throttle curve of 100, 75, 62.5, 50, 62.5, 75, 100 provide full throttle for inverted maneuvers.

• Throttle Hold pitch curve: Start with the normal pitch curve (for inverted autos, start from the idle-up 3 pitch

curve), but increase the last point approximately 1-2°, if available, to ensure sufficient pitch at landing.

This default recommendation assumes you are doing forward flight. If you are just learning, please follow your

instructor's guidance. Some instructors like a +1 base point for training so that the helicopter comes down

very slowly, even if your instincts pull the throttle/collective stick to the bottom in a hurry.

Adjustability:

• Normal condition curves are editable in the BASIC menu for convenience.

• All curves may be adjusted in the ADVANCE menu.

• Automatically selected with the proper condition.

• The idle-up curves are programmed to maintain constant RPM even when the collective pitch is reduced

during flight (including inverted).

• To change which condition’s curve is being edited, cursor up to <COND> and change the curve named.

• For clarity, the name of the condition currently active (switched on in the radio) is shown in parentheses

behind name of condition whose curve is being edited. (Example: see curve displays below. Note that the

normal condition is active but the idle-up 1 condition’s curves are currently being edited.

• Moving and deleting the curve point: The curve point (-stk-) can be moved to the left or right by turning the

DIAL (up to 2% in front of the adjoining point) and deleted/returned by pressing the DIAL for one second

alternately.

• Idle-ups and throttle hold pitch curves may be edited even before the conditions have been made active.

Activating their throttle curves activates these conditions.

Radiolink Electronic Ltd

www.radiolink.com

5.3.2 REVO MIX:

This 5-point curve mix adds opposite rudder input to counteract the changes in torque when the speed and

collective pitch of the blades is changed.

Adjustability:

• Three separate curves available: normal for hovering; idle-ups 1 and 2 combined; and idle-3.

• Normal condition curves are editable in the BASIC menu for convenience.

• All curves may be adjusted in the ADVANCE menu.

• Correct mix is automatically selected in-flight with each condition and automatically activated when the

throttle setup for that condition is activated in the programming (i.e. THROTTLE HOLD or THR-CURVE.)

• To change which condition’s curve is being edited, cursor up above POINT5 and select. For clarity, the name

of the condition currently active (switched on at the radio) is shown in parentheses behind the name of the

condition whose curve is being edited.

Revo. Mixing rates are 5-point curves. For a clockwise-turning rotor, the rudder is mixed in the clockwise

direction when collective pitch is increased; for counterclockwise-turning, the opposite. Change the operating

direction setting by changing the signs of the numbers in the curve from plus (+) to minus (-) and vice versa.

Suggested defaults:

Clockwise rotation: -20, -10, 0, +10, +20% from low throttle to high.

Counterclockwise rotation: +20, +10, 0, -10, -20% from low throttle to high.

Adjust to the actual values that work best for your model.

Revo. Curves for idle-ups are often v-shaped to provide proper rudder input with negative pitch and increased

throttle during inverted flight.(Rudder is needed to counter the reaction whenever there is increased torque. In

inverted flight, throttle stick below half has increased throttle and negative pitch, therefore increasing torque

and rotating the helicopter unless the revo. Mix is also increasing appropriately.)

Note: The throttle and pitch curves for the normal condition is always on. They cannot be inhibited. The

other four conditions are activated with their throttle curves or throttle hold.

• THR-CURV/NOR: Inputs the normal (NORM) throttle curve, which is usually not a linear response to

THROTTLE STICK motion. Adjusting point 4 of the curve adjusts the engine's RPM at the THROTTLE STICK

midpoint, the desired position for hovering. The other 6 points are then adjusted to create the desired idle and

Radiolink Electronic Ltd

www.radiolink.com

maximum engine speed, and a smooth transition in-between.

• PIT-CURV/NOR: inputs the normal (NORM) collective pitch curve, the collective pitch curve for flight near

hover. The normal collective pitch curve is adjusted to match the throttle curve, providing the best vertical

performance at a constant engine speed, with a starting curve of 4 base, +5 neutral, and +8 to +10 degrees of

blade pitch maximum. You can program the response over a 7-point curve for the best collective pitch angle

relative to THROTTLE STICK movement.

• REVO./NORM: mixes collective pitch commands to the rudder (a PITCH-RUDDER mix) to suppress the

torque generated by changes in the main rotor's collective pitch angle, keeping the model from yawing when

throttle is applied.

Note: There are three revo, mixes available: normal (NORM), idle-up 1/2 (IDL1/2), and idle-up 3 (IDL3). All

3 are adjustable in the ADVANCE menu. Never use revo mixing in conjunction with heading-hold/AVCS gyros.

5.3.3 GYRO SENSE

About GYRO SENSE, please refer to 3.3.12, by following steps:

5.3.4 THROTTLE HOLD

This function holds the engine in the idling position and disengages it from the THROTTLE STICK when

SWITCH AT9 is moved. It is commonly used to practice auto-rotation. Prior to setting up THR-HOLD, hook up

the throttle linkage so that the carburetor is opened fully at high throttle, then use the digital trim to adjust the

engine idle position. To have THR- HOLD maintain idle, move the THROTTLE STICK to the idle position,

then move the hold SWITCH on and off and keep changing the offset value until the servo does not move. To

lower the engine idle speed, or if you want to shut off, input a more negative number.

Adjustability:

• Idling position: Range of -50% to +50% centered about the throttle idle position to get the desired engine

RPM.

• Switch assignment: Assigned to SWITCH E(AT10) or G (AT10) down. Adjustable in the CONDITION

(THR-HOLD item), (2-position type switch only)

• Throttle curve: Since the throttle is moved to a single preset position, no curve is available for THR-HOLD.

• Collective pitch curve: Independent curve, typically adjusted to create a blade pitch range of -4% to +10% to

+12%, is automatically activated with THRHOLD.

• Revo. mix: Since revo. mix adjusts for torque from the engine, no revo. mix is available for THR-HOLD.

• Priority: The throttle hold function has priority over idle-up. Be sure that the throttle hold and idle-up

SWITCHES are in the desired positions before trying to start the engine. (We recommend starting your

engine in throttle hold for safety reasons.)

• Gyro: Gyro programming includes an option to have a separate gyro setting for each condition, including

THR-HOLD. This avoids the potential problem of the user being in the wrong gyro setting when going to

THR-HOLD, resulting in an improper rudder offset and the model pirouetting.

5.3.5 HOVERING ADJUSTMENTS (HOV-THR and HOV-PIT):

Hovering throttle and hovering pitch are fine-turning adjustments for the throttle and collective pitch curves

individually, affecting performance only around the center point and only in the normal condition. They allow

in-flight tweaking of the curves for ideal setup.

Adjustability:

• Rotor speed changes caused by temp., humidity, altitude or other changes in flying conditions are easily

accommodated.

• Both adjustments may be inhibited if not desired.

• Both adjustments may also be set to NULL, temporarily turning off the knob but maintaining the last

memorized setting.

• Adjustments may be memorized and then the knobs returned to center point to use that amount of

adjustment, allows easy use of the trimming knobs for multiple models. (Note that when memorization is

repeated with the knob offset from center, the trim value accumulates.)

• Adjustments are quickly reset to the initial value by turning the dial until the trim reads 0%, memorizing, then

returning the knob to its center position.

• Note that all functions, including these, assume the model hovers at half stick.

•Available in normal (NORM) or normal/ idle-up1 (NORM/IDL1) condition only.

5.3.6 HIGH/LOW PITCH (HI/LO-PIT):

This function may be used to adjust the curves high and low side

individually for each flight condition (normal, idle-up 1, idle-up 2, idle-up 3,

throttle hold).

Adjustability:

• You may define high and low side rate trim knobs (the high side pitch trim

control is defined as the right side lever at initial setting).

• The conditions are activated in the CONDITION SELECT function.

• Both adjustments may be set to MANUAL, temporarily turning off the knob.

• Adjustments may be memorized and then return the knobs to center point to use that amount of adjustment,

allows easy use of the trimming knobs for multiple models.

5.3.7 OFFSET

Optional separate trims in addition to those for the normal condition. This

function is used to automatically change the trim of a helicopter, for example,

when transitioned from hover to flying at high speed. A clockwise-rotation

rotor helicopter tends to drift to the right at high speed, so an aileron offset

may be applied to offset the helicopter to the left.

The necessary elevator offset varies with model geometry, so it must be

determined by noting collective pitch changes at high speed. The rudder

offset is affected by both revo. mixing and trim lever movement while in the

offset function.

Adjustability:

• Complete switch assign ability, plus a CONDITION option that creates/ switches between individual trims for

each of the idle-ups.

• When OFFSET is active (its switch is on), moving the TRIM LEVERS adjust the stored offset, not the trims in

the normal condition.

•When OFFSET is inactive (its switch is off), the OFFSET and any trim adjustments to it have no effect (model

obeys the trim settings of the currently-active flight condition.)

• When OFFSET is inhibited, trim adjustments made in any flight condition affect all flight conditions.

• Rapid jumps caused by large offsets can be slowed using the DELAY function.

• During OFFSET operation, the aileron, elevator, and rudder travels are displayed on each trim display in the

Startup screen.

Note: Remember, offsets and revo mixes are not recommended when using heading-hold/AVCS gyros

because they conflict with the automatic corrections to trim and torque that AVCS provides.

5.3.8 DELAY:

The Delay function provides a smooth transition between the trim positions whenever OFFSET, REVO,

MIXING, or THROTTLE HOLD functions are turned on and off.

5.3.9 GOVERNORS:

The Governor mixing function is used to adjust the Governor speed settings (rS1, rS2, rS3) from the

transmitter.

What is a governor? A governor is made up of a set of sensors which read the RPM of the helicopter’s head,

and a control unit that automatically adjusts the throttle setting to maintain a constant head speed regardless

of changes in pitch of blades, weather conditions, etc. Governors are extremely popular in competition

helicopters due to the consistency provided.

How does it help in helicopter setup? The governor eliminates the need to spend large amounts of time

setting up throttle curves, as it automatically adjusts the engine’s RPM to maintain the desired head speed.

Adjustability:

• On/off may be separate from speed switching by plugging

governor on/off into CH8 and changing CUT-CH setting.

• If using separate on/off, switch assignment is totally adjustable.

Radiolink Electronic Ltd

www.radiolink.com

Be careful not assign governor off to a condition switch if you

want the governor to function in that condition.

• Speed switching and governor ON/OFF may be together using one switch or ON/OFF switching may be

performed using an independent switch/channel.

• When speed setting control uses CH7 and separate ON/OFF switch is not used, CH8 can be used for other

functions.

• In-flight adjustment of the head speed (for easy adjustment during turning) may be created using an

additional channel and a programmable mix.

The GV-1 controls throttle when it is active, so the throttle will not obey any Failsafe settings preset for

throttle in the transmitter. Always set the Failsafe setting for the GV-1's on/off channel to OFF. This way the

governor is shut off and the throttle obeys the Failsafe throttle commands.

5.3.10 Throttle Mixing (THROTTLE MIX):

This function can be set for each flight condition, and is used

to correct the tendency of the model to change altitude when

the rotor is tilted by aileron, elevator, and rudder controls.

Adjustability:

• Mixing may be set from 0 to 100% each flight condition.

5.3.14 CONDITION

Revo., curves for idle-ups are often v-shaped to provide proper

rudder input with negative pitch and increased throttle during

inverted flight. (Rudder is needed to counter the reaction whenever

there is increased torque. In inverted flight, throttle stick below half

has increased throttle and negative pitch, therefore increasing

torque and rotating the helicopter unless the revo. mix is also

increasing appropriately.)

Additional flight conditions are available specifically for helicopters. These additional flight conditions contain

different throttle curves, collective pitch curves, revo. mixing, and trims (except IDLE-3) to make the

helicopter perform certain maneuvers more easily. Lastly, the gyro and dual rate functions may be set to

provide separate rates per condition selected, including one for each idle-up.

Additional idle-ups may be used to maximize the helicopter's flight characteristics in certain types of flight

(i.e. fast forward motion, backward) or maneuvers (loops, rolls, stall turns), or even the same maneuver but

changing from heading-hold/AVCS gyro mode to normal gyro mode. The AT9 provides 3 idle-ups to allow

the modeler 3 additional setups along with the normal flight condition. (Note that IDL3 does not include

governor settings.)

Adjustability:

• SWITCH G (AT9) or E (AT9) is programmed for normal (NORM), idle-up 1 (IDLE-UP1), and idle-up 2

(IDLE-UP2) curves, adjustable in CONDITION SELECT (IDLE-UP1/2, IDLE-UP3 items).

(IDLE-UP1/2 3-position type switch only, IDL3 2-position type switch only)

• Activated with the throttle curve for that condition in THR-CURVE.

• Curves are adjusted to maintain constant RPM even when the collective pitch is negative (inverted). Note

that REVO mixing has one curve for idle-ups 1 and 2 and a second curve just for idle-up3.

•Gyro settings may be set separately for each idle-up.

• Governor settings may be set up to follow Normal/Idle1/Idle2, but do not offer a setting to adjust for each of

the 5 conditions like gyro.

• Activating OFFSET makes the TRIM LEVERS adjust the trim separately in each of the idle-up conditions.
