RE: GP Patriot 40 Kit Build
The 60 plus size engines that will rev-up seem to be able to get the Patriot 40 to the range that it flies best at (fast). The 46-55 sport engines won't give it enough speed unless a tuned pipe is used and even then it is not going to move real fast. I want the 150+ mph range but as someone just mentioned, I can't afford it right now. The 90 size engines aren't any larger or heavier than the 60 size that someone mentioned. The 60/90 engine will require many modifications such as, they will need extra fuel tank above wing with pluming and mods to fuse to compensate.
The Patriot just doesn't fly that well below 100mph.
