I have the Como 75 so I need to use it. I guess I'll go with the pipe, but what about props? Would a 12x10 be enough or should I try a 13x8? I'm flying it this weekend so I need to determine what I should start with. What rpm (realistic) should I be looking for on this engine with the pipe? The engine is used, but not damaged in any way. Thanks guys for all of your input.

Hope you have a wonderful weekend.[sm=sunsmiley.gif]
