Just thought I'd revisit the thread that inspired the most fun plane I've ever flown. It's still evolving. The latest has an almost flat wing with a much rounder leading edge (Imagine that Cajun!) and the flight charicteristics keep getting better! Like I've mentioned previously, I know little about aerodynamics...I just build em and try em. This airfoil would be an interesting one to anylize. High alpha crawls, hover, and inverted pitch response in incredable, the wing refuses to stall, and yet full throttle stability is solid as a rock. Flat spins, especially inverted beat anything I've ever flown, and if done just right, can actually gain altitude in the spin.
