APC AP0505EP PROPELLER 5x5EP ELECTRIC REVERSE/PUSHER FOR SPEED 400 MOTOR  [AP0505EP]

Propeller purpose and installation

This APC AP0505EP 5x5EP propeller is an RC-scale accessory designed specifically for electric reverse/pusher arrangements driven by Speed 400 motors. It functions as a basic thrust-generating component and is intended for use on small electric models where the motor rotation and propeller orientation require a reverse or pusher setup.

When fitting the propeller, verify the motor rotation direction and orient the blade to produce thrust in the intended direction. Confirm shaft diameter and use the correct adapter or collet for a secure mount, check for sufficient prop-to-structure clearance, and fasten the propeller to the shaft following standard RC mounting practice.

Tuning with this propeller focuses on balance and clearance rather than complex aerodynamic trimming. Static balance reduces vibration that can affect motor bearings and ESC performance, while small adjustments to mounting position and spinner or hub alignment help maintain consistent thrust in pusher configurations.

Routine checks before each run should include verifying the propeller is free of nicks, confirming secure attachment, and ensuring there is no contact with airframe or nearby components when the motor is powered. Treat the item strictly as an RC propeller and do not imply use on full-scale vehicles.
