good working diagram nick!
thomas, what would the rate of decent be to stall the blade (not just the root) at 100% rpm? pretty scary i would imagin, can your downwash be that fast? otherwise you would be in auto, wouldnt you?
when learning to fly, VRS had me scared so my instructor took me out to show me it. we had the needle peged at 2000 fpm and came out quite easily. we used a fair bit of collective too, dont think we got to 7000 fpm though.
