GP cap 231 ex ??
I just aquired one this summer too. It's a bit over powered with the Saito 180 I've got on the front......extremely unlimited vertivcal. I strengthened the firewall with gussets, and additional ply along with fiberglass. I also strengthened the fuselage where the landing gear attaches (just from what I've herd around here). It flys absolutly beautifuly, but with too much elevator throw it will snap. I've got pictures if you're interested!!
