BMathews I think you win the DR. IQ candy bar. Your comment on the leading edge was spot on. I went and looked at it, and recalled that I used a piece of 3/4 triangle, for the purpose of getting a good snap. It seems I got all I bargained for, and then some. The only question is why always to the right? I would think that the torque of the motor would skew it to the left.. I have this plane trimmed to fly right in all modes. Funny that a few degree too much elevator produces such a vicious snap. Again guys thanks alot.
