I can actually snap my Dragon Lady at will. It's because I've sealed the gap for the elevator (they're quite effective/responsive). The plane is setup for the recommended deflection on low rates and 1/4 of an inch more than the recommended setup on high rates. And crosswind is absolutely correct that you can in fact snap regardless of speed. I was able to snap both at the top and bottom of a loop while traveling at a good clip, the wing just plane looses the lift due to the angle of attack and snap. It's the neatest thing and can be incorporated into some fancy aerobatics if done intentionally, or nail-biting if not expected and low. And Ed is right, the Dragon Lady is a great aerobatics plane. Knife Edge ain't Extra- or Cap- worthy, but the plane tracks extremely neutral (bank it and it stays banked until you move the controls again), and is super responsive. But it slows down very fast and can land slower than my Avistar.

I've taken my new-to-me Dragon Lady up for about a dozen flights to date, and I like it more each time... Too bad they discontinued it.
