Yesterday we had a pair of flat bottom foam wings with 432 sq inches of area (I will shorten the cord on subsequent wings and narrow the thickness of the wing from 1.25inch to 1.00 inch) flying SSC with a pizza box (not a good combat plane) and had a blast!!! I believe that you guys are flying aircraft that are meant to be flown very fast to fly well (very aerodynamic that is thin on the ends, fully and semisemetrical wings) with smaller engines that can't pull the airframes fast enough to get enough lift. This is why you are stalling aircraft. The design needs to be made with alot of lift (such as a flat bottom) so that at these slow speeds the aircraft does what you tell it. We flew these slow defenders with stock 25's and .28s, but got our butts kicked by the shreveport crew in class B, but they fly much, much better as SSC ships. I have yet to stall one out. I'll post a picture this afternoon to give you an idea of what we built.
