RE: OS91FX RECOMMENDED PROPPELLER
You may wish to run the engine with a lighter load than we would run here. Try an APC 14 x 8, maybe an APC 13 x 8. The engine will handle running up to the high 11,000's in RPM, so if you have the engine running well, any propeller that will let the airplane fly well is correct.
