Hi Everyone
This is my setup
gamepad (logitech f350) -> QGC -> wifi -> raspberry pi -> telemetry 1 -> pixhawk (PX4 flight stack)
I set COM_RC_IN_MODE to 1 (disable RC check)
I am able to fly quadcopter in stabilize/manual mode quite well. But when I switch it to ALTCTL mode, I can not take it off using gamepad. Increase throttle do not increase motor spin rate. If I take it off in stabilize mode and change it to ALTCTL mode, nothing happens. Quadcopter lose altitude if I release throttle stick (just like stabilize mode, you have to hold some throttle to let quadcopter hover). However AUTO_LOITER mode works quite well. Do I miss something? Or gamepad / joystick is only for stabilize mode only?
Thank you very much
