I'll tell ya what I think. You ready? You are right about the profiles being better at Harriers, because of their fuselages, not their wing tips. That's what I think. What do I know? My Funtana rocks uncontrolably in a harrier, and I wish I had a four stroke in there to get that torque I need at low rpm's. I'm not too proud to modify the airplane till it flies the way I want it to. It may take a few months to get it right, but it will be much better when I am finished with it. Right now the weather sucks and the field is under water.[&o]
