 Thanks for sharing the background on the flap fences.  Ted has such a
 "different" machine" that it will be interesting to see what the stall speed
 turns out to be.  Too bad we couldnt get some "before and after" data.
 
 Anyway, it will be interesting to see it they can survive your passengers
 big feet.  Thanks again, Bill Hogarty
