If so put a 46fx on a Panther and hold on. If combat in your local area uses a lot 46's you will have a great plane for combat. But I don't see a lot of "C" class on the different contest calendars.
A 25fx, Norvel.25, Jett .25 or .30 or an Irving .25 will keep your plane performing right up with the big boys in RCCA "B" combat.
