APC AP13047SFP PROPELLER 13x4.7SFP ELECTRIC SLOW FLYER REVERSE/PUSHER  [AP13047SFP]

Slow-flyer reverse/pusher propeller

This APC AP13047SFP propeller is an RC-scale accessory intended for electric slow-flyer models and pusher or reverse mounting arrangements. It is designed to be used where lower speed, smoother thrust delivery and stable low-RPM handling are required in model aircraft.

Compatibility is determined by your airframe's mounting orientation and motor shaft or adaptor fit. Before installing, verify hub fit and spinner clearance on the airframe, and ensure the prop orientation matches the intended thrust vector for pusher or reverse setups. Do not assume a prop will fit without checking physical dimensions on your model.

Installation notes: fit the prop according to your motor or adaptor manufacturer's guidance, secure with the correct nut or retaining hardware, and confirm proper rotation direction for the mounting (pusher vs tractor). Balance the propeller on a prop balancer and check for vibration at low RPM before full-power tests. Small adjustments to thrust line or motor timing on the ESC can help when fine-tuning handling in slow-flight regimes.

Tuning role: on slow flyers this propeller affects climb rate, cruise speed, and motor load at low RPM. Use it to achieve smoother throttle response and predictable low-speed handling while monitoring motor temperature and current draw to avoid overloading the system.
