APC AP11045MR PROPELLER 11x4.5MR ELECTRIC MULTI ROTOR  [AP11045MR]

Propeller for Electric Multirotors

This APC AP11045MR 11x4.5MR propeller is a replacement blade sized for electric multirotor models. It serves as a direct spare for setups that accept 11-inch class props and is intended for hobby-scale multirotor use only. The blade profile and 4.5-inch pitch are design descriptors, used to match rotor loading and flight feel during tuning and repairs.

Material is a molded plastic composite that balances durability and cost; inspect each prop before flight for cracks, nicks, or warping. Installation requires the correct hub orientation and secure fasteners to the motor shaft or adapter used on your frame. Confirm thread direction and torque according to your motor and prop mount type to avoid loosening in operation.

Balancing and trimming remain important with any replacement prop. Check static balance on a blade balancer and make minor trimming adjustments as needed to reduce vibration that can affect flight controllers, ESCs and motors. Small imbalances can change flight characteristics, so re-check balance after any trimming or repeated impacts.

When tuning flight performance, swap props while keeping other variables constant to isolate propeller effects on thrust, responsiveness and battery draw. Use this prop as a straightforward option for routine maintenance, bench testing, and tuning sessions on electric multirotors where an 11x4.5 size is appropriate.
