APC AP0505EP 5x5EP Electric Reverse/Pusher Prop for Speed 400  [AP0505EP]

Intended use and fit tips

The APC AP0505EP 5x5EP propeller is an RC accessory meant for electric reverse or pusher configurations driven by Speed 400 motors. It serves as a thrust-producing component for small electric models where blade orientation is reversed from tractor setups.

Fit the propeller by first confirming motor rotation and orienting the blade to deliver thrust in the required direction. Match the shaft diameter and install the correct adapter or collet for a secure fit, check prop clearance, and secure the prop according to standard RC practices.

Tuning focuses on static balance and clearance rather than aerodynamic trimming. Balancing the prop lowers vibration that can stress motor bearings and ESCs, and fine adjustments to the hub or spinner alignment preserve smooth thrust in pusher layouts.

Carry out routine checks before each session: inspect for damage, ensure the prop is tight, and confirm there is no contact with the airframe or components when the motor is running. This product is for RC use only and not for full-scale applications.
