Reverse-Thrust 5x5EP Propeller Compatible with Speed 400 APC AP0505EP  [AP0505EP]

Overview and fitting pointers

This APC AP0505EP 5x5EP propeller is intended as an RC accessory for electric reverse or pusher installations using Speed 400 motors. It is designed to provide thrust in assemblies where prop orientation and motor rotation are set for pusher operation.

When fitting, confirm the motor spins in the expected direction and position the prop to produce thrust the right way. Verify shaft diameter, fit an appropriate adapter or collet for a secure mount, check clearance from the airframe, and fasten the propeller as per normal RC mounting procedures.

Fine-tuning is generally limited to balancing and clearance checks rather than advanced aerodynamic setup. Static balancing cuts down vibration that can harm motor bearings and ESCs, and small hub or spinner adjustments will help maintain steady thrust in pusher configurations.

Carry out pre-flight inspections: look for blade nicks, ensure the prop is tightly fixed, and confirm there is no interference with the airframe or nearby components when the motor runs. Use this item only as an RC propeller and do not imply full-scale use.
