Quadplane Losing main plane motor, switch to Quad mode?

Just wonder if this is already a build-in safety feature, when Quad plane loses the main plane motor or for some reasons it can’t seems to maintain the right altitude and plunging, It will automatically switch to quad copter mode and use quad motor to substain flight?

I believe Q_ASSIST is what you’re looking for but I defer to the experts.

Good luck.


This is great as well. thanks.
