Smart RTH
When the GPS signal is strong (satellite connections ≥ 7), press the " "
button. The transmitter will beep once, indicating that the Smart RTH is
activated. The drone will start flying back to the Home Point automati-
cally.
During the RTH procedure, if the pilot pushes the left joystick up or
presses the " " button again, the drone will exit the RTH procedure
immediately.
The RTH (Return to Home) function can bring the drone back to the last
recorded Home Point. There are three kinds of RTH: Smart RTH, Failsafe
RTH, and Low Voltage RTH.
This function can only be activated when the drone is in GPS mode.
Home Point: The drone will mark the first location where it receives a
strong GPS signal (satellite connections ≥ 7) during the flight or takeoff
as the Home Point.
The Failsafe RTH will be activated when:
1. The drone receives a strong GPS signal (satellite connections ≥ 7);
and
2. There is a pre-recorded Home Point; and
3. The connection between the transmitter and the drone is lost for
more than 6 seconds.
Once the Failsafe RTH is activated, the drone will start to to fly back to
the pre-recorded Home Point automatically.
If the connection between the drone and the transmitter is re-estab-
lished during the Failsafe RTH procedure, the drone will stop flying back
to the Home Point, and the pilot will regain control of the drone.
Failsafe RTH
RETURN TO HOME

① The First Stage of Low Voltage RTH: The drone status LED starts to
flash red slowly and the transmitter keeps beeping. The drone enters
the first stage of Low Voltage RTH. There are two possible returning
procedures: (After the activation of the first stage of Low Voltage RTH,
a "safety zone" with a height of 98 ft and a radius of 164 ft will be
generated with the Home Point as its center. Once the drone returns to
the airspace above the Home Point (thus ending the RTH procedure),
it can only fly within the safety zone.)
Low Voltage RTH
a. If the flight altitude is higher
than RA and the flight distance is
larger than 16ft, the drone will
first fly back above the Home
Point, descend to 49ft and hover
there. The first stage of Low
Voltage RTH ends.

②The Second Stage of Low Voltage RTH: When the drone status LED
starts to flash red quickly, and the transmitter keeps beeping, the drone
will enter the second stage of Low Voltage RTH. There are two possible
returning procedures:
b. If the flight altitude of the drone
is lower than 49 ft, the drone will
first ascend to 49 ft, fly back above
the home point, then slowly
descend to the ground.
a. If the flight altitude of the drone
is higher than or equal to 49 ft,
the drone will, while maintaining
its current altitude, first fly back
and hover above the home point.
It then slowly descends to the
ground.

- During Low Voltage RTH, the pilot cannot terminate the
procedure.
- During RTH, the drone cannot avoid obstacles.
- If the GPS signal is weak or unavailabe, the RTH cannot be
activated.
- If the drone receives not GPS signal, and the connection between
the drone and the transmitter is lost for more than 6 seconds, the
RTH cannot be activated. The drone will just descend to the ground
and locks its motors.

APP OPERATION INSTRUCTION

Headless Mode
The Headless Mode is a great training tool for beginner pilots. It is also
useful when the drone is too far from the pilot (which makes it difficult
to tell its orientation). It keeps the drone traveling forward, backward,
left, or right when you move the right joystick in those directions,
regardless of which way the front of the drone is pointed.
1. First tap the " " icon on the app interface, then select " " icon
by tapping on it. Follow the instructions in the prompt box to activate
Headless Mode.
2. Tap the " " icon again. The drone exits Headless Mode.
APP OPERATION INSTRUCTION
The pilot should stay facing the same direction that
the drone’s head points to when it takes off.
-33-

* Why is the orientation of the drone important?
In normal flying mode, the control of the drone movement can
sometimes be counter-intuitive for beginners. For instance, when the
drone is in the air with its head pointing to your right, if you push the
right joystick forward, the drone will fly to your right, instead of flying
forward.
With the headless mode, the drone has a fixed "head." In Headless
Mode, the drone always remembers the side its head points to during
