APC AP04747EP 4.75x4.75 EP Reverse/Pusher Prop for Speed 400 Motor  [AP04747EP]

EP propeller for reverse and pusher setups

This APC AP04747EP prop is a direct RC-scale replacement rated 4.75x4.75 for EP electric use, referencing Speed 400 motor applications. It suits model builders fitting reverse or pusher prop layouts on smaller electric craft where correct prop orientation and sizing are important.

Labelled diameter and pitch (4.75x4.75) are used by pilots and tuners to approximate thrust and the electrical load on a Speed 400 motor; compare these figures with your motor RPM and expected operating range. As the unit is intended for reverse/pusher use, confirm the motor rotation direction and the hub fastening method before final installation.

Fitting guidance: inspect shaft diameter and select a matching adapter, ensure the prop sits square on the hub, and secure the retainer to prevent movement. After installation do a static balance, then a cautious low-power run to check for vibration or elevated current draw. If required, tweak battery, ESC settings and gearing to control motor temperature and current in Speed 400 setups.

Tuning note: using this prop lets you experiment with pitch and orientation to refine climb, cruise speed or static thrust on small electrics; pitch changes will affect acceleration and top RPM.
