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

EP propeller suitable for reverse or pusher mounting

This APC AP04747EP propeller is an RC replacement part listed as 4.75x4.75 for EP electric applications that reference Speed 400 motors. It is made for builders who use reverse or pusher prop configurations on smaller electric models where matching prop size and rotation orientation to the motor is critical.

The marking 4.75x4.75 denotes nominal diameter and pitch, which modelers use to gauge thrust and motor loading relative to the Speed 400 motor's RPM. Given the reverse/pusher designation, double-check motor rotation and your chosen hub adapter before completing installation.

Installation guidance: confirm the shaft diameter and adapter compatibility, ensure the prop seats squarely on the hub, and secure retaining hardware to prevent slippage. After fitting, perform static balancing and a cautious low-throttle check to detect vibration or excess current. Adjust gearing, battery selection and ESC parameters as required to control motor temperature and current for Speed 400 builds.

Usage note: this prop provides a simple method to test pitch and orientation effects on climb, cruise and static thrust in small-scale electric models; altering pitch or direction will change acceleration and steady RPM characteristics.
