APC AP0947SFP Electric Slow-Flyer Reverse/Pusher 9x4.7 Propeller  [AP0947SFP]

Overview of reverse/pusher prop for slow flight

The APC AP0947SFP propeller is made for RC electric slow-flyer models that require a reverse or pusher mount. Refer to the 9x4.7 sizing when checking spinner, hub, and motor compatibility to ensure proper fit.

Practical notes for hobbyists:

• Compatibility: Intended for installations calling for a 9x4.7 reverse or pusher prop; confirm adapter and spinner compatibility before final installation.
• Pre-install checks: Inspect blades for any imperfections, confirm alignment of the mounting boss with the shaft, and perform a static balance to minimise vibration at low RPMs.
• Installation tips: Make sure the prop face is correct for pusher use, fasten hardware evenly, and validate balance after the prop is secured.
• Tuning role: The 9x4.7 size influences static thrust and low-end response; pair the prop with motor and ESC settings that support smooth slow-speed operation.
• Safety: Keep hands clear when powering the model and conduct low-throttle bench runs to confirm stability and fit.
