I find the Tailwind and Buttercup to be fascinating aircraft. But I always wonder about the effectiveness of the Trapezoidal Wing Tips. I have read that Steve did a test flight with just one tip installed, and that the wing with the tip rose first and required aileron input to counter. But that could be attributed to the additional span. So I'm wondering about their effectiveness. I don't think Mr. Wittman would ever keep something that made the plane (any plane) slower, but not sure how he felt about handling.

Have any forum members flown a Tailwind without and with the tips and noted the performance and/or flight control changes?
