low G on helicopter.. I would think mean .. .no lifties
So all i'm comparing, is the flight regime, and that both types of air craft have their own problem that arises if you do the wrong things at that state.

I get it.
"Retreating blade stall" means that the retreating main rotor blade is indeed stalling in the classic sense. It generally happens at high speed (relative to a helicopter) and the retreating MRB, which is aero designed just like a fixed wing, stalls. It can be disastrous from a control perspective: part of the main rotor is producing lift, another part is in stall. The helo will generally depart controlled flight.
For classic "no lifties" look up "vortex ring state" and "power settling" (sometimes called settling with power)...Everything is working except the lifties are gone
