Before the FW-190 had it's mid-air I increased the angle of incidence by placing a 1/4" strip of wood at the T.E. The airplane still nosed over a bit at full power/high speeds, but only a little. Also the tendency to climb at lower speeds was also significantly reduced. I think the problem lay in the bit of down thrust I accidentally built into the airplane. The tail surfaces may also be the problem, but other planes we built exactly to scale never had the same problems. I think it's all just a big balancing act with theses scratch built machines. Thanks for the info, and I'll pay a little more attention to the angles on my FW-190 'the second'.
