I had good luck with the Arsenal VG-33 from RCM plans. Lazerworks.com has a short kit. The plans are available on Outerzone. It uses a Sig WWII canopy. A fast stable flier, just don't over do it with the elevator. I've had 3 Arsenals and a half dozen other 1/12 scale warbirds and they all could be induced into a high speed snap roll with too much elevator.
