Any wing LE shape within reason can be forced to snap or spin. The larger LE radii require much more elevator to initiate. To me, more throw is not whatI want to produce the same effect
That's the reason I like sharper LE's on the wing. Less throw on the control surfaces is necessary to initiate. Servos are happier, airframe is happier, and lower throw helps exit on line better.
I am looking for something totally different than the sport fliers do. In competition, we perform these aerobatic maneuvers for a score so everything is important. In sport flying, as long as the crate remains intact, anything goes. There is no need to tune the commands for a refined response
What I implied is minimizing the workload of the pilot during competition flying. My implication didn't translate well considering the comments I saw. In my last paragraph above, I think I stated my position...
My original argument stands....as an experiment, one can figure out how much command is required to make a model (with a thick wing and blunt LE) snap roll
Then do the same after taping a sharp LE to the outboard one foot or so of span. The sharp LE isn't elaborate...just a thin 3/32"-1/8" thick strip of balsa, about 1/2" wide. Dick that goes for the Edge wing too, but you may already know that answer
