Step 2C. Propeller Selection and Installation
Please refer to the propeller selection chart below to determine the
proper size and pitch for break-in applicable to your engine size.
IMPORTANT: Prior to installation, be sure to balance the prop.
Unbalanced props are not only dangerous to operate, but can
lead to premature parts failure on both the engine and model.
Tightly secure the prop. Remember to inspect the prop
thoroughly for any nicks or signs of fatigue which can lead to
prop failure.
