RE: gp at6 texan arf v/s ys 91 ac
Tim I have a KMP texan which is the same specs as the gp only mine is fiberglass. Little heaver I think. I have a saito 50 in mine and it is very fast at full throttle but it is still controllable. I don't think I would go over max recommended engine. from my experience I for see nothing but problems and headaches. good luck
