Speed 400 Reverse/Pusher Propeller APC AP0505EP  [AP0505EP]

Purpose and fitting notes

This APC AP0505EP 5x5EP propeller is an RC-scale accessory intended for electric reverse or pusher arrangements driven by Speed 400 motors. It provides thrust for small electric models where motor rotation and blade orientation require a pusher configuration.

When installing, check motor rotation and align the blade so it produces thrust in the correct direction. Confirm shaft diameter and fit the correct adapter or collet for a firm mount, ensure adequate prop-to-structure clearance, and secure the propeller to the shaft following standard RC mounting practice.

Tuning with this prop focuses on balance and clearance rather than aerodynamic trimming. Static balancing reduces vibration that can harm motor bearings and ESCs, and small adjustments to mounting position or hub alignment help keep thrust steady in pusher layouts.

Before every run, inspect the propeller for nicks, verify tight attachment, and make sure there is no contact with the airframe or nearby parts when the motor is powered. Treat this item solely as an RC propeller and do not imply use on full-scale vehicles.
