I have raced pylon racers in 60 mph gusts off of the coast of Florida. makes it a real trick in landing dead stick!
I enjoy flying my Wacky-Bee III in 20+ mph winds because I can hover it in a knife edge. If I raise the nose at about 45 degrees, high alpha knife edge manuver, I can get it to perform a knife edge elevator. I really enjoy that! Its something that you don't see very often
A buddy of mine that gotten the Wacky-Bee III to fly backwards in a KE in a 20 +/- mph wind. I've seen him do it, but I haven't been able to do it yet, but I'm still trying!
