APC Props Slow Fly 7 x 4 RC Propeller - APC07040SF

The APC Props 7x4 Slow Fly propeller (APC07040SF) is a fixed-pitch RC aircraft prop designed specifically for slow-fly and indoor fixed-wing models. APC's Slow Fly range is engineered to produce efficient thrust at low motor RPM, making this prop well suited to lightweight park flyers, foamies, and electric slow-fly builds where a standard propeller would over-pitch the airframe. The 7-inch diameter and 4-inch pitch combination strikes a balance between lift and efficiency for small electric aircraft running brushed or brushless motors in the appropriate power band.

Key Features

• 7-inch diameter with 4-inch pitch, optimised for low-RPM slow-fly and indoor electric aircraft
• Slow Fly blade geometry produces efficient thrust without requiring high motor speeds
• Moulded from APC's glass-filled nylon composite for consistent balance and durability
• Standard centre bore — may require a collet or prop adapter to fit your motor shaft
• Compatible with typical slow-fly power systems running small brushless or brushed outrunners

What's Included

• 1 x APC 7x4 Slow Fly propeller (APC07040SF)
