Electric Slow-Flyer Reverse/Pusher Prop APC AP11047SFP  [AP11047SFP]

Design intent and use for slow-flyer pushers

The APC AP11047SFP is supplied as a scale replacement for electric slow-flyer aircraft set up in pusher or reverse orientations. The SFP aero section offers steady, forgiving thrust characteristics suited to low-speed flight and relaxed handling profiles.

Installation needs careful checking of rotation direction and mount alignment: verify that the blade pitch faces the correct way for pusher thrust, and use the appropriate adapter or nut to secure the prop to the motor shaft. Because it is intended for reverse/pusher mounting, confirm the hub seating is correct so the propeller does not rub on the airframe or mounting structure.

Balance the prop before flight to keep vibration low and protect airframe and electronics. After fitting, monitor motor/ESC load during a static test and make minor alignment or spacer adjustments to improve low-speed controllability without modifying motor components.
