This APC AP13045MRP propeller is an RC-scale replacement designed for electric multirotor use where reverse or pusher orientation is required. The 13x4.5MR marking identifies the diameter and pitch format used by multirotor builders and tuners to match thrust and motor characteristics.
Intended role: fine-tuning thrust and propulsion behaviour on electric RC multirotors. Fitment notes: confirm the motor shaft diameter and mounting method on your motor before installation, orient the propeller for the specified reverse or pusher rotation, and ensure secure seating and tight locking of the prop nuts or adapters.
Pre-flight checks: inspect for chips, cracks, or warping and replace if any damage is found, and balance the propeller to reduce vibration for consistent flight performance.
