11x4.5MR APC AP11045MR Replacement Blade for Electric Multi Rotor  [AP11045MR]

Replacement Blade for Multi Rotor Use

The APC AP11045MR 11x4.5MR propeller serves as a spare blade for electric multirotors that accept 11-inch class props. The specified 4.5-inch pitch and blade profile describe expected rotor loading and handling characteristics for tuning or repairs.

Manufactured from a molded plastic composite, the blade strikes a balance between toughness and cost. Inspect each prop before flight for nicks, cracks or warping and replace any blade showing damage that could worsen in use.

Correct installation requires matching hub orientation and using the proper fastener arrangement on your motor shaft or adapter. Verify thread direction and tighten to the torque appropriate for your mount to minimize the chance of in-flight loosening.

Balancing and small trimming adjustments are critical to reduce vibration. Use a static balancer to check the APC AP11045MR and perform minor corrections as needed, then retest balance after trimming or impacts. Swap props methodically during tuning to observe thrust, responsiveness and battery draw differences.
