APC Props Slow Fly 10 x 4.7 RC Propeller - APC10047SF

The APC Props 10x4.7 Slow Fly propeller (APC10047SF) is a fixed-pitch RC aircraft prop designed specifically for slow-fly and park flyer electric models where efficient thrust at lower speeds is the priority. APC's Slow Fly series is widely used in the RC aircraft community for its consistent moulding quality and reliable balance straight from the pack. The 10-inch diameter paired with a 4.7-inch pitch makes this prop well suited to lighter electric airframes that run smaller brushless or brushed motors at moderate RPM.

Key Features

• 10-inch diameter with 4.7-inch pitch — a combination tuned for slow-fly and park flyer performance rather than high-speed flight
• Moulded from APC's standard glass-filled nylon material, offering a good balance of stiffness and resistance to minor tip strikes
• Designed for efficient low-speed thrust, helping park flyer and foamie models fly at realistic, manageable airspeeds
• Consistent factory balance reduces vibration at the motor, which is particularly beneficial on lighter airframes with limited vibration tolerance

What's Included

• 1x APC 10x4.7 Slow Fly propeller
