RE: Knife edge wing
Sort of like the weight rule. Hardly ever enforced, so let's get rid of it.
Draw out a 2mm radius leading edge. There probably wasn't a model out there that would have passed the rule if enforced. The Contest Board is a very funny committee to deal with. Probably if I had tried to eliminate the entire rule it wouldn't have passed. But keeping the wording "knife-edge wings" and just eliminating the measurement got it approved by a 9-2 vote. Really a stunning victory. Maybe next time someone can propose to eliminate it entirely.
Ryan maybe?
