So does that mean that the SPA will be outlawing porting,polishing and blueprinting of O.S. 91's any time soon to keep cost's down I mean.
As far as AMA pattern being a showcase for how much money you can spend. I won the nats (advanced) last year with a plane that was close to 3 years old and about 6+ year old design with a minimum 1200+ flights on it. Not exactly a showcase of money spent.
Imac I have no idea about as that type of flying is not my bag so to speak.
