Attention
：
To ensure the return to home point as precise as possible, please fly the aircraft in open
area (no tall buildings in 50 meters of radius, flat in 10 meters of radius) with the GPS
working well. Then the return to home function will be able to activate.
● With the GPS positioning mode turned on, it will automatically enter auto return to home
mode if the remote controller loses control.
● Once the RTH mode is enabled, if the aircraft flies below 30 meters of altitude, the aircraft
will automatically ascend to 30 meters before returning to home point. if the aircraft flies
over 30 meters of altitude, the aircraft will return to home point at the current altitude. Please
do not use other functions during the process of return. Please ensure there are no
obstacles in way of return in case of any potential accidents.
Optimal Transmission Zone
Please fully extend the antennas before the flight. The signal is weak directly above the antenna.
The signal between the aircraft and the remote controller is most reliable when the antennas are
positioned in relation to the aircraft as depicted below.
Ensure that the aircraft is flying within the optimal transmission zone. To maintain optimal
transmission performance, adjust the remote controller and antennas and keep the space
between controller and aircraft clear during the flight.
