APC 11x4.7 SF Pusher Prop

Optimize the thrust and efficiency of your aircraft with the APC 11x4.7 SF Pusher Prop. Engineered specifically for slow flyer configurations and multirotor setups requiring reverse rotation (Pusher/CCW), this high-quality composite propeller delivers predictable performance, quiet operation, and exceptional durability. Molded from rigid, lightweight composite material, it maintains its pitch profile even under high load, ensuring your propulsion system runs smoothly and reliably.

This propeller is a versatile choice across several key markets. In the RC hobby and FPV market, it serves as an excellent replacement or upgrade for park flyers, specialized fixed-wing twin-engine platforms, and multirotor drones requiring balanced, counter-rotating thrust. For the educational and STEM market, its straightforward dimensions and reliable performance profiles make it ideal for classroom aerodynamics experiments and custom student scratch-builds. For sUAS contractors and commercial enterprise developers, this standard off-the-shelf propeller functions as a dependable, highly repeatable surrogate tool for bench testing motor performance, prototyping custom vertical takeoff platforms, or serving as a backup replacement for light industrial fleets.

Note: This is a Slow Flyer (SF) profile propeller designed specifically for electric motors operating at low to medium RPM ranges. It is not intended for high-RPM applications or gas engines.

Key Features:

• Pusher/Reverse Configuration: Molded specifically for reverse rotation setups, making it the perfect match to counter-rotate alongside standard tractor props.

• Slow Flyer Profile: Featuring wide, sweeping blades optimized for low-RPM efficiency, maximizing thrust for park flyers, 3D foamies, and slow-cruising aircraft.

• Rigid Composite Construction: Built with APC's proven composite blend to minimize blade flexing under heavy load, ensuring stable tracking and long-term durability.

• Adapter Ring Set Included: Arrives with a matching set of precision centering locating rings to accommodate a wide variety of motor shaft diameters seamlessly.

• Smooth and Quiet Profile: Computer-optimized blade aerodynamics reduce vibration and drag, providing a quieter flight experience and smoother onboard video capture.
