RTH-Process
1. Record "Home Point"
2. Trigger return conditions
3. Adjust the direction of the head
4. Return to the return altitude set by APP
(1) Regardless of the current height of the aircraft, if the aircraft is within 5 meters of
the horizontal distance, land directly;
(2) If the horizontal distance is 5 meters away and within 20 meters, return at the
current altitude;
(3) In 20 meters away, if the altitude of aircraft is more height than the return altitude,
it will return directly; If no, it will rise to up to the return altitude ,and then RTH;
5. Search for the drone apron during the landing process (Make sure this function is
on).
Low Battery RTH
The flight controller will display a notice when a low battery warning is triggered. The
aircraft will automatic ally return to the Home Point if the current power is
enough,otherwise it will land directly. when without GPS signal or signal is not strong
that will land directly.
Performance requirements:
(1) The appropriate low-voltage protection voltage is automatically calculated
according to the altitude and distance of the flight.
(2) After the low power forced landing or crash, if the power is lower than 10%, enter
the protection mode: turn off the picture transmission, but save normal data
communication.
Failsafe RTH
When the aircraft loses connection with the remote control for more ® than 5
seconds, the aircraft automatically returns or land directly. Performance
requirements:
(1) After the aircraft loses control for 5 seconds, it triggers automatic return.
(2) If the connection is restored during the return flight, the return flight can be
cancelled.
(3) Landing directly when there is no GPS signal or the signal is not strong.
