Depending on the engine crankshaft size, the propeller may need to be reamed to a larger size using GPMQ5005 (SAE) or GPMQ5007 (Metric).
Four-stroke engines are typically higher torque engines and should use the larger props indicated in the range. Recommended prop ranges will vary depending on your particular engine and airplane. The Chart below represents average prop usage and should be used as Only a General Guideline. Always refer to the manufacturer's instructions included with your engine.
