APC AP13047SFP Slow-Flyer Reverse/Pusher Propeller 13x4.7SFP  [AP13047SFP]

Propeller for slow-flyer pusher mounts

The APC AP13047SFP propeller is intended for electric slow-flyer airframes in pusher or reverse mounting arrangements, offering smoother thrust delivery and predictable low-RPM handling for scale practice flights.

Compatibility depends on your airframe's mounting orientation and the motor shaft or adaptor fit. Before fitting, verify hub seating and spinner clearance on the model, and make sure the blade orientation matches the desired thrust vector for pusher or reverse setups. Do not assume fit without checking the prop's physical dimensions against your model.

Installation notes: follow your motor or adaptor manufacturer's guidance, secure the prop with the correct nut or retaining hardware, and confirm the correct rotation direction for the chosen mounting (pusher vs tractor). Balance the prop on a prop balancer and run a low-RPM check to detect vibration before full-power testing. Minor adjustments to thrust line or ESC timing can help fine-tune low-speed handling.

Tuning role: on slow flyers this propeller influences climb rate, cruise speed, and motor load at low RPM. Use it to smooth throttle response and maintain consistent low-speed behavior while monitoring motor temperature and current draw to avoid overloading the system.
