Ever heard of Wikipedia.
I Edited the Retreating blade stall article. to now include;
"It should be noted that at the onset of RBS. It is the tip of the Blade (Where Relative Airspeed is Higher) that stalls entirely. it has been noted that the tip will start to stall at around the 10 O'clock and be at greatest effect at 9 O'Clock and be unstalled by the 7 O'Clock position. It seems almost unlikly that this should happen due to the AoA being less at the tip from built in washout, but non the less, as you increase speed for an Airfoil such as comonly used in Heli, the Stall angel reduces. thus the tip is in stall. So the Root of the retreating blade is not stalled but in a very low lift condition."
