APC AP08045MRP 8x4.5MR Propeller for Electric Multi-Rotor Reverse and Pusher  [AP08045MRP]

8x4.5MR multirotor propeller

This APC 8x4.5MR propeller is an RC-scale blade designed for electric multi-rotor use in reverse and pusher configurations. Its 8x4.5 designation identifies blade diameter and pitch for hobby multirotor setups, and the reverse/pusher capability means the same blade can be oriented to produce forward or rearward thrust depending on mounting direction.

Installation notes focus on correct orientation and secure mounting. Fit the propeller to the appropriate hub and ensure the rotation direction matches the motor and flight controller setup, then tighten the fastening hardware to prevent slippage. Check the mounting interface for compatibility before first use and inspect for any cracks or damage each flight.

Tuning and trimming benefit from simple, repeatable steps: balance the blade before installation to reduce vibration, confirm thrust direction after mounting, and use incremental motor and ESC adjustments rather than large changes. This propeller serves as a tuning element to influence thrust and efficiency in small electric multirotor rigs without requiring drivetrain modifications.
