These competitions are relatively new to me, but after watching a few videos, I've gained a lot of respect for the guys who do it. These guys are flying on the edge of a stall, and it requires a great deal of familiarity with the aircraft, and the flying skill to be able to be competitive in this sport. Unfortunately, the nature of the sport involves great risk. This accident caught my eye as the pilot was flying the same model plane I soloed in on my 16th birthday. My Dad used to own one. Hopefully accidents like this are few and far between, as sport flying is becoming more and more scarce...
