APC Props Slow Fly 9 x 7.5 RC Propeller - APC09075SF

The APC Props 9x7.5 Slow Fly propeller (APC09075SF) is a dedicated slow-flyer prop designed for electric fixed-wing RC aircraft that operate at lower airspeeds and higher throttle settings. APC's Slow Fly range is optimised to generate efficient thrust at reduced RPM, making it well suited to park flyers, foamies, and other lightweight electric models where a standard prop would either over-rev or produce inefficient airflow. The 9-inch diameter paired with a 7.5-inch pitch gives a balance of lift and forward pull that works well with lower KV brushless motors commonly found in this class of aircraft.

Key Features

• 9-inch diameter with 7.5-inch pitch, sized for lightweight park flyers and slow-speed electric models
• Slow Fly geometry produces efficient thrust at low RPM, reducing motor strain compared to standard props of the same size
• Moulded from APC's rigid composite material for consistent balance and reduced vibration in flight
• Suitable for pusher or tractor configurations depending on motor and airframe setup
• APC09075SF style code makes sourcing a direct replacement straightforward

What's Included

• 1 x APC 9x7.5 Slow Fly propeller

What You Need

• Compatible brushless or brushed electric motor with an appropriate KV rating for 9-inch props
