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

Electric Multi-Rotor 11x4.5MR Propeller

The APC AP11045MRP propeller is an aftermarket replacement made for electric multirotor rigs that need a reverse or pusher blade. The 11x4.5MR designation describes the blade diameter and pitch used in prop selection for multirotor tuning.

Fit the blade so it matches motor rotation and the role of the mount, checking whether a forward-pulling or rear-pushing face is required. Confirm the prop is properly seated on the motor shaft and that the securing hardware is fastened before conducting a low-throttle bench test to verify correct spin direction and clearance.

Prior to the first flight, inspect the prop for nicks, deformities, and carry out static balancing where practical to reduce vibration through the powertrain. Note that swapping reverse and pusher props will affect thrust vectoring and aircraft trim; modify flight controller parameters or motor timing to achieve smooth hover and better power efficiency.
