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

11x4.5MR Propeller for Electric Multi-Rotor Use

This APC AP11045MRP propeller is a replacement blade intended for electric multi-rotor craft that require a reverse or pusher orientation. The 11x4.5MR marking denotes the diameter and pitch used when selecting props for multirotor performance tuning.

Fit the propeller so the blade face matches the motor rotation and the aircraft role, noting whether the mount needs a forward-pulling or rear-pushing blade. Ensure the prop seats fully on the motor shaft and that the fastening hardware is torqued correctly before doing a low-throttle bench spin to confirm direction and clearance.

Inspect blades for nicks or deformation before each first flight and perform static balancing where possible to reduce motor and ESC vibration. Remember that switching reverse/pusher props changes thrust direction and trim; update flight controller trims or motor timing as needed to regain a stable hover and efficient power consumption.
