APC AP11045MRP Propeller 11x4.5MR Electric Multi-Rotor Reverse Pusher  [AP11045MRP]

11x4.5MR Electric Multi-Rotor Propeller

This APC AP11045MRP propeller is an RC-scale replacement designed for electric multi-rotor platforms where a reverse or pusher orientation is required. The 11x4.5MR marking identifies blade pitch and diameter sizing used in tuning prop selection for multirotor setups.

Install the propeller in the orientation that matches motor rotation and flight role, paying attention to whether the mount position requires a forward-pulling or rear-pushing blade face. Verify proper seating on the motor shaft and secure fastener engagement before bench testing at low throttle to confirm correct direction and clearance.

Before first flight, check the blade for nicks or deformation and perform static balance if possible to reduce vibration through the motor and ESC. When tuning, note that swapping reverse/pusher props can alter thrust vector and trim; adjust flight controller settings or motor timing as needed to achieve stable hover and efficient power draw.
