11x4.5MR APC AP11045MRP Reverse Pusher Prop for Electric Multirotors  [AP11045MRP]

11x4.5MR Multi-Rotor Reverse/Pusher Prop

This APC AP11045MRP propeller serves as an RC replacement for electric multirotor systems that need a reverse or pusher blade. The 11x4.5MR stamp identifies the prop diameter and pitch commonly used when matching props to motor and flight requirements.

Install the prop so the blade face corresponds to the motor rotation and the aircraft's intended role, taking care to note forward-pulling versus rear-pushing orientation. Verify the prop is correctly seated on the shaft and that the nut or adapter is tightened properly prior to any bench testing at low throttle to check rotation and clearance.

Before flying, examine each blade for chips or warping and, if possible, perform static balance to cut down on vibration transmitted to the motors and ESCs. Keep in mind that moving between reverse and pusher propellers affects thrust vectors and trim; adjust controller settings or motor timing to restore stable hover and optimal efficiency.
