8x4.5MR Reverse/Pusher Multirotor Propeller by APC AP08045MRP  [AP08045MRP]

8x4.5MR propeller characteristics

This APC 8x4.5MR propeller is tailored for electric multirotor hobby use and supports both reverse and pusher mounting options. The size and pitch marking identify expected performance characteristics for common small multirotor rigs, and the reversible form factor provides mounting flexibility to suit different airframe layouts.

During installation, check that the hub and spinner interface match the propeller bore and that motor rotation corresponds with intended thrust. Tighten mounting hardware securely and perform a hands-off spin check at low throttle to confirm no wobble. Inspect blades for any damage before each flight to maintain safety.

For trimming and tuning, balance the blade prior to fitting to reduce vibration, confirm thrust direction once mounted, and adjust motor and ESC settings gradually to reach desired handling and efficiency. The propeller acts as a tuning tool to influence thrust characteristics on lightweight multirotors.
