APC AP11045MR 11x4.5MR Multirotor Replacement Propeller  [AP11045MR]

Multirotor Replacement Prop

The APC AP11045MR 11x4.5MR propeller is supplied as a hobby-scale replacement for electric multirotor platforms accommodating 11-inch class props. The 4.5-inch pitch and blade geometry describe the expected loading and flight characteristics used during setup and repairs.

Made from a moulded plastic composite, the prop provides a pragmatic balance of resilience and cost. Inspect the blade and hub for any signs of damage, distortion or wear before every flight and replace if any defect is found.

Ensure correct hub orientation and use the appropriate adapter, washer and fasteners for your motor shaft. Check thread direction and tighten to the manufacturer recommendations for your motor mount, and re-inspect security after the initial flight.

Balancing remains essential: check static balance and make small corrections with adhesive or careful trimming, then retest. When tuning, swap propellers methodically so changes in thrust, handling and current draw can be clearly attributed to the prop choice.
