In a fixed wing the reason you feel a buffet during stall is because the seperated airflow passes through the elevator (a canard stalls its front elevator first so i imagine you still get a buffet). A helicopter shedding vortices at its rotor blade tips is sure to suffer blade vortex interaction (BVI) between tail rotor and main rotor. So the solution is to design a rotor system that achieves its downwash distribution without shedding tip vortices. Queue the ring-rotor....
Maybe Bug will take the opportunity to parade his innovation.

All i need now is the balls to try it
