Platform:
- ArduPlane 4.5.7
- Quadplane VTOL 4+1
Issue:
During AUTO and CRUISE transitions, the pusher motor spins up to approximately 25% throttle and stays there during the airspeed wait phase. The aircraft does not accelerate forward, instead it drifts around unpredictably and never builds enough airspeed to complete the transition. The aircraft seems to do this indefinitely until the pilot intervenes.
Transitioning to FBWA works correctly every time.
