I'm just wondering about prop size for the engine.

Trust me--a 60cc engine ain't gonna do much with an 18 pound plane at 5973' above sea level. [] The 76cc Husky is fine. I just need to know what kind of power it has. Ralph told me it should run like a Q75. Thats helpful, but most guys using the Q75 have it in a 45 pound warbird with a little bitty prop and massive pitch. Like a 22-14 or something crazy like that. I need a prop for an IMAC plane. I'm thinking 24-10, but just not sure if the motor can turn it. It's a chainsaw engine, so it's gotta run up in the 7000RPM range or it's gonna be a turd.
