Blueline.....While I have never owned an Aviation Models Aircraft, I can personally attest to their quality and reliability. My brother owns ever size "YAK" they sell from the 40% down to the 87" 30%. He will not buy anything else and he has never had any kind of problem except that some of the monokote trim pulled up and had to be ironed back down. As for the profile plane, I have no knowledge. But, it's always been my experience that if a company puts out several quality products, they would not risk their reputation over an inferior model. Especially an Profile. Good luck if you decide to get one. Bob
