you don't fly these small fast ones then hey Mike?
here when the quickies go up the lumbers are normally smart enough to wait 5 mins or stay the hell out of dodge. when those are up the patten suddenly becomes a vertical U shape with all passes sub 20' over the patch.
everyone else stays in the center of the huge U and theres never been a fast job midair. however, a Rapier did once hit a sport plane taking off, the sport plane took off in the wrong direction ( cross wind ) and also didn't allow for the low pass the Rapier was already on over the far side of the patch ( on purpose as he was low enough to hit anyhting on the patch and he knew the sport was sitting there so went wide to try and avoid ) the Rapier was bits, the sport climbed out stuck at half throttle with bits of Rapier hanging everywhere. another pilot took control did a low pass which ended in a fast landing in long grass.
Nothing came of it, but in this case it was the sport pilot at fault as he hadn't waited and took off in the wrong direction.

mine the other day is just what happens if your gonna prophang as close as you can to someone who only really got the hang of it the same day, good reason for SPA3D's

here fast planes arnt persecuted just because they have different needs and flight pattern. bit of a waste if your only going to do fast passes upwind and 50' up in an oval.
