一、 INTERFACE
RSSI Connect to receiver RSSI channel
PPM Connect to SBUS/PPM
A1 Extend other functional interfaces
A2 Extend other functional interfaces
AIL Aileron servo interface
ELE Elevator servo interface / Airspeed interface
THR ESC interface
RUD RUD servo interface
GPS Connect to GPS
PMU Power/Camera/VTX/Current, all in one interface
Connect AirSpeed Meter
Step1: set AUX1/AUX2 channel as ELE function
Step2: connect ELE servo to AUX1/AUX2 channel
Step3: connect airspeed meter to ELE channel
Step4: power on again
If you should change ELE servo direction, you should set AUX1/AUX2 channel direction
Power Supply
All above interfaces are powered by the external 5v BEC module, and the flight controller does not output 5V to supply power
to these interfaces.
二、 FLIGHT MODE
MANUAL Remote control directly controls the aircraft
STAB Auto level
HORIZON ACRO mode + STAB mode
RTH Return to home
HOVER Altitude hold and cycle。
ALTHOLD Aircraft hold altitude and flight route(with GPS)
GUID Keep on the route
ACRO Gyro mode
SUB-MODE
Switch mode to slave mode
RTH Mode
When the return altitude is higher than the set height, for example, returning at a height of 150m. If the set return altitude is 120m,
the aircraft will return at a height of 150m, and then decrease the altitude to 120m when approaching the home position. If the return
altitude is less than 30m, the aircraft will climb to 30m before turning. The RC cannot control the aircraft during the RTH mode, but the
throttle can be raised by the throttle stick.
In auto cruise mode, the throttle is automatically calculated based on the speed(airspeed or ground speed). In the case of a
downwind or a large wind, the throttle can be raised by the remote control to prevent the aircraft from stalling. for example if auto
