8x4.5MR Propeller for Electric Multirotor - APC AP08045MRP  [AP08045MRP]

8x4.5MR multirotor blade design

This APC 8x4.5MR propeller is an RC-scale blade crafted for electric multirotor applications where reverse or pusher mounting is required. The 8x4.5 marking denotes diameter and pitch for common hobby multirotor setups, and the reversible design lets the same blade be mounted to produce forward or rearward thrust depending on motor rotation and hub orientation.

Installation guidance emphasizes correct orientation and firm fastening. Fit the propeller to a compatible hub, confirm the rotation direction matches your motor and flight controller settings, and tighten the fastening hardware to prevent slippage. Inspect the mounting interface for compatibility before first use and check for any cracks or damage prior to each flight.

Tuning tips include balancing the blade before installation to reduce vibration, verifying thrust direction after mounting, and making small incremental adjustments to motor and ESC settings for efficient trimming. This propeller is useful as a tuning component to refine thrust and efficiency in small electric multirotor rigs without altering the drivetrain.
