Leading edge droop

Yep, drooping the leading edge like the big boys do might work nicely. There must be some math behind that.
Once Dave releases some, all kinds of experiments will likely develop for these particular platforms. There might even be a whole thread on performance tips and tweaks. Wouldn't be the first time I trashed some gliders thinking I had discovered the holy grail of sink rate . Some day, I will tell you the story of when a flight instructor cut the power on a 172 on approach to show me how the glider guys did it .
