I recently received a super tigre 61 x series engine in near perfect condition. I also received the exhaust tube and a pipe with it but I am new to racing and don't know much about using a tuned pipe. I know if the pipe isn't right the engine will never step up on it. I'm going to mount it on a hangar9 t-34 that I reserected after the last speedworld warbird race. I put the plane on a major diet and cut anything off that wasn't absolutely necessary. I'm also not sure what prop and fuel I should use. I know there are alot of pattern guys out there with alot of experience in this area so any advice would be invaluable. I have plenty of time on this, I'm not planning on competing with this plane till next october, but R&D time is crutial. Thanks guys.
