Well what about the 6 degree positive incidence I think I heard someone mention? The most I've heard of on other models is 2 Degrees . It seems that the 6 d is contributing to the sensitive pitch problem . I think built in washout would be better than twisting the wing because, It would be a lot more accurate with a straight leading edge and just the rear situated upwards. When you hand twist a wing and reheat it , couldn't that again spring out of adjustement on a hot day for example?Another thing that could happen with twisting is that the leading edge could twist into a negative incidence . Also would they lose twist at an even rate? I'm not doubting what your info on the fat fuse and the stab size , that makes sense . It's just that some Geebees seem to have no probs while others are really bad and they all have the fat fuse in common .
