Introduction
The Agras MG-1 (abbreviated as MG-1) is a battery-powered multirotor aircraft designed for
agricultural applications in variety of environments and terrains, including terraces, elds, forests
and orchards. It is dust-proof, water-proof (IP43 protection rating, IEC standard 60529) and made
of anti-corrosive materials, allowing it to be rinsed clean.
The MG-1 also includes DJI’s industry-leading flight control system and three useful Operation
Modes: Smart, Manual and Manual Plus. A microwave radar underneath the aircraft makes the
MG-1 uniquely versatile across different terrains and the combined Altitude Stabilization System
automatically maintains the aircraft’s height above plants to ensure optimal spraying.
The remote controller features a Spraying Status Panel decorated with intuitive icons and a range of
controls for navigation, mode and spraying. While the MG-1 does all the hard work in the elds, you
keep full control over it in the palm of your hands.
Feature Highlights
The MG-1 provides three useful Operation Modes: Smart, Manual and Manual Plus.
In Smart Operation Mode, the aircraft will travel along a pre-planned route and spray liquid payload.
Users can set the operation gap, ying speed and other parameters. The MG-1 can cover an area of 7-10
acres per hour.
In Manual Operation Mode, users can start and stop spraying manually and also adjust the spray rate.
In Manual Plus Operation Mode, the flying speed is restricted and the aircraft’s heading is locked.
Except for the heading, users can control the movement of the aircraft.
The MG-1 also includes two intelligent memory features: operation resumption and system data
protection. When the operation mode is changed from Smart Operation Mode, operation resumption
records a set point for the aircraft to return to when Smart Operation Mode is reinstated. System data
protection keeps the system data for a period of time even when powered off so users can resume their
missions after replacing the battery.
The spraying system includes a spray tank, sprinklers and other accessories. The four sprinklers placed
on the aircraft’s two sides provide well-distributed spraying and great coverage. The nozzles on the
Agras MG-1 can also be swapped out to meet the needs of different applications.

Altitude Stabilization System
Profile
To ensure that the spray is evenly dispensed, the aircraft uses the radar module on the Altitude
Stabilization System to maintain the same distance above the crops at all times. The radar module is
enabled by default, and can be disabled in MG-1 Assistant. If it is enabled, the aircraft will y above
the crops at a constant spraying distance in Smart Operation Mode and Manual Plus Operation
Mode. The system can also measure the spraying distance above the crops or other surfaces, but
the aircraft will not be able to y at a constant spraying distance when performing this function.
How to Use
1. Ensure that the Operation Mode Switch is toggled to the Manual Operation Mode. Fly the aircraft
above the vegetation and adjust the spraying distance between the aircraft and the vegetation. DO
NOT operate the aircraft above vegetation beyond the detection range (1.5 - 7 m) while adjusting
aircraft altitude, otherwise the Spraying Status Panel will not be able to display the current spraying
distance.
2. Conrm the desired spraying distance by observing the Height LEDs on the Spraying Status
Panel. Ideal spraying distance should fall within the working range (2 - 3.5 m) for altitude
stabilization. DO NOT operate the aircraft beyond this range, otherwise the system will become
unstable.

If the MG-1 loses GPS signal and flies out of the max radius but regains GPS signal
afterwards, it will y back within range automatically.
No Fly Zones
All restricted areas are listed on the DJI official website at http://www.dji.com/fly-safe/category-
mc. Restricted areas are divided into category A and category B. Category A areas cover major
international airport such as LAX and Heathrow, while category B areas includes smaller airports.c
Category A Safety Zone (requires GPS)
• The category A “safety zone” is comprised of a small “no-y zone” and a range of “restricted-
altitude zones”. Flight is prevented in the “no-y zone” but can continue with height restrictions in
the restricted-altitude zone.
• 1.5 miles (2.4 km) around a designated safety zone is a no-fly zone, inside which takeoff is
prevented.
• 1.5 miles (2.4 km) to 5 miles (8 km) around restricted areas are altitude restricted, with maximum
altitude going from 35 feet (10.5 m) at 1.5 miles (2.4 km) to 400 feet (120 m) at 5 miles (8 km).
• A “warning zone” has been set around the safety zone.

4. The Aircraft Status Indicator shows the current flight mode when calibration is complete. If
the Aircraft Status Indicator becomes blinking red, repeat the steps above to recalibrate the
compass.
When to Recalibrate
1. The compass data is abnormal, and the Aircraft Status Indicator is blinking red and yellow
alternatively.
2. Flying in a new location, or a location that is different from your last ight.
3. The mechanical structure of the MG-1 is changed.
4. Severe drifting occurs in ight, i.e. the MG-1 has difculty ying in a straight line.
Calibrating the Compass
The compass is built in the landing gear. Be sure to calibrate the compass before your rst ight,
or else the aircraft cannot work properly. The compass is a very sensitive instrument that requires
regular calibration to ensure optimal flight performance. Abnormal compass data due to a lack
of calibration can lead to poor ight performance or even failure. Regular calibration enables the
compass to keep optimal performance.
DO NOT calibrate your compass where there is a chance of strong magnetic interference,
such as magnetite quarries, parking structures, and underground steel reinforcements.
DO NOT carry ferromagnetic objects such as cellular phones with you during calibration.
DO NOT calibrate besides massive metal objects.
DO NOT calibrate in an indoor space.
Calibration Procedures
Choose an open space to carry out the following procedures. It is recommended to calibrate the
compass with an empty tank.
1. Flip the Flight Mode Switch back-and-forth at least 6 times, until the Aircraft Status Indicator
becomes solid blue.
2. Hold the aircraft upright and rotate it 360 degrees along the central axis, until the Aircraft Status
Indicator changes from solid blue to solid green.
3. Hold the aircraft with its nose facing up and rotate 360 degrees along the central axis.

Stopping the Motors
There are two methods to stop the motors.
1. When the aircraft has landed, push the throttle stick down, then perform the CSC command to
stop the motors. Release both sticks once the motors have stopped.
Starting and Stopping the Motors
Starting the Motors
The Combination Stick Command (CSC) listed below is used to start/stop the motors. Ensure you
perform the CSC in one continuous motion. The motors will begin to speed at an idle speed. Take
off immediately after the motors are spinning, or else the aircraft may lose balance, drift or even
takeoff by itself and injure nearby people.
Flight Test
1. Place the aircraft near the operation area with the Aircraft Status Indicator facing you.
2. Power on the remote controller. Connect the battery to the communication port and then the
XT90 port.
3. Toggle the Operation Mode Switch to Manual Operation Mode.
4. Toggle the Flight Mode Switch to P-mode. Wait until there is no red blinking from the Aircraft
Status Indicator, which means the GPS signal is strong. Then perform CSC command to start the
motors.
5. Push the throttle stick up to take off.
6. Select the desired Operation Mode and spray liquid.
7. To land, ensure the Operation Mode Switch is toggled to Manual Operation Mode and hover over
a level surface and gently pull down on the throttle stick to descend slowly.
CSC 1 CSC 2 CSC 3 CSC 4
2. When the aircraft has landed, push the throttle down and hold. The motors will stop after 3
seconds. (In M-mode, when “M” is set as Manual mode in the MG-1 Assistant, use method 1 to
stop the motors.)

8. After landing, perform the CSC command to stop the motors.
9. Disconnect the battery from the XT90 port and then the communication port. Then power off the
remote controller.
When the Aircraft Status Indicator blinks blue during flight, the aircraft has entered
Failsafe mode.
The low battery level warning is triggered when the Aircraft Status Indicator blinks yellow.
Fly the aircraft back and land it as soon as possible, then stop the motors and replace the
battery.
The critically low battery level warning is triggered when the Aircraft Status Indicator
blinks red. The aircraft will begin to descend and land automatically. You can change the
settings in MG-1 Assistant so that the aircraft does not automatically descend and land
when the Aircraft Status Indicator LED blinks red.
