Dick & Mike,

This is really interesting to me. My background is kind of 'book learnin' aerodynamics, and the notion of 'beneficial' stall for aerobatics is new to me. In that light, the comments you make about thin wings for pattern planes are certainly consistent with the stall behavior of thin wings that has been understood for a long time. Are all the maneuvers the same for full size aerobatic aircraft? Do they also use thin wings for the same reason?

Thanks,
