APC AP11047SFP Electric Slow Flyer Propeller Reverse/Pusher  [AP11047SFP]

Electric slow flyer reverse/pusher propeller

This APC AP11047SFP propeller is an RC-scale replacement part intended for electric slow-flyer aircraft fitted in reverse or pusher orientations. The listing identifies the unit as a propeller designed around slow-flyer (SFP) characteristics, which are typically chosen for low-speed stability and controllable thrust in park- and trainer-style models.

Installation requires attention to rotation and mounting direction: verify the propeller face and pitch orientation match the intended thrust direction before securing to the motor shaft, and use the correct adapter or nut for your motor. Because this propeller is specified for reverse/pusher use, confirm the hub seating and shaft engagement are correct for pusher mounting to avoid rubbing against the airframe or mounting plate.

Tuning considerations focus on balance and prop-to-motor matching. Static balance the propeller before flight to reduce vibration that can affect airframe and electronics, and check motor/ESC loading after fitting a new prop to ensure the combination remains within safe operational limits for your motor and electronic speed controller. For trimming, small changes in propeller alignment and pinion/spacer setup can improve low-speed handling without altering motor hardware.
