QHover is our standard recovery mode from any issue or failure in forward flight. I’m pretty confident that can be used in most QP airframes, provided they are not underpowered and can’t physically overcome the forces on recovery. It’s still advisable to have the throttle stick more than half otherwise the plane will descend or might not recovery in time.
Ideally setting up and using Q_Assist properly would avoid any stall from happening in the first place (apart from manual that is used in the video here to stall). Typically that results in no tip stall, and it will simply transition to hover the more it slows down if you have the forward speed set above the stall speed of the aircraft. Not as dramatic, but you should never see a stall again on a QP! This is the beauty of having two separate lift and control systems on-board at the same time. Either can fly the aircraft.
