I agree with ALMOST everything mitch said. I had the Cermark with a Saito 1.80 and my first GP had a Taurus 52 and my cuttent GP has a ZDZ 60. The GP does bounce a little on landing (I have to order the TNT replacement gear) but my biggest concern is wheather you want to fly glow or gas-with the choices being simple after that decision. The good news is that you are a winner either way.

PS--I own 3 giant scale planes and 2 of them are Pitts. One GP and the other Miles Reed Challenger. ILOVEAPITTS
