I am using a Tilt VTOL with a vectored yaw setup. When arming the plane in QStabilize mode, the control surfaces remain inactive until switching to FBWA. However, at times, they move even when armed in QStabilize mode.
Whenever the control surfaces remain inactive in QStabilize mode, the transition is smooth. However, when they move while armed in QStabilize mode, the plane tends to nose-dive during transition.
Could this issue be related to parameter settings?
