APC AP08045MRP 8x4.5MR Multirotor Prop - Reverse/Pusher Compatible  [AP08045MRP]

Overview of the 8x4.5MR prop

The APC 8x4.5MR is an RC-scale multirotor prop built for electric craft where reversible mounting is needed. The 8x4.5 spec indicates the blade diameter and pitch used by hobby pilots, and the reversible feature lets operators use the same blade for forward or rearward thrust depending on how it is mounted.

For installation, ensure the prop is seated on the correct hub and that motor rotation aligns with the chosen thrust direction. Secure the propeller with the manufacturer's recommended hardware and inspect the mount for proper fit before first operation. Regularly examine the blade for chips or cracks to avoid in-flight failures.

When tuning, start by balancing the blade to limit vibration, confirm thrust direction after mounting, and adjust motor and ESC parameters in small steps to refine performance. This propeller aids in tuning thrust and efficiency on small electric multirotor setups without mechanical drivetrain changes.
