APC AP1107SFP 11x7 Electric Slow-Fly Reverse/Pusher Propeller  [AP1107SFP]

APC AP1107SFP Low-Speed Reverse/Pusher Propeller

This APC AP1107SFP is an RC-scale propeller built for electric slow-fly models that require either a pusher setup or a reversed rotation installation. The 11x7 marking denotes the nominal diameter and pitch, which helps match the prop to motor Kv and ESC choices for calm, low-speed handling.

Fit and compatibility: fit this propeller to lightweight slow-fly airframes that accept the hub bore and thread pattern. Check hub diameter and thread direction before installation, and ensure the motor rotation is set correctly for the intended thrust orientation when using it as a pusher or reversed mount.

Installation tips: orient the hub faces to suit the thrust direction of your model, tighten the retaining nut securely but do not over-torque, and apply thread locker where specified by the airframe. Always perform a static balance and a low-throttle spin test before the first flight to confirm smooth operation.

Tuning role: the AP1107SFP is intended to increase static thrust at low RPM for predictable slow-speed control and efficient power use on electric slow flyers. If you observe vibration or weak climb, check balance, motor timing and ESC settings, and consider only minor prop size changes within the range recommended by your motor or airframe.
