Select a propeller that will allow the engine to turn in the high 10,000's on the ground. Any prop that will allow the engine to turn that RPM and fly the model the way you want is the correct one.

Since we've not done much in the way of 3D-type work, we're only used to standard type props. We usually run an APC 13x8 prop in our tests. We've seen them turn in the low 11,000's at times, if the engine's been broken-in very well.

If you have to reduce the pitch, then up the diameter. Keep the RPM in the suggested range for best throttle handling.
