APC Props 9 x 4.7 Slow Fly RC Aircraft Propeller - APC09047SF

The APC Props 9x4.7 Slow Fly propeller (APC09047SF) is a fixed-pitch RC aircraft prop designed specifically for slow-flying electric fixed-wing models. APC is one of the most widely trusted propeller brands in RC aviation, and the Slow Fly series is engineered with a higher pitch-to-diameter ratio optimised for the lower airspeed and torque characteristics of slow-fly and 3D-style aircraft. At 9 inches in diameter with a 4.7-inch pitch, this prop suits a broad range of park flyers, foamies, and electric trainers where smooth, efficient thrust at moderate RPM is the priority.

Key Features

• 9-inch diameter with 4.7-inch pitch, purpose-built for slow-fly and 3D electric aircraft

• Slow Fly blade profile generates strong thrust at lower motor RPMs compared to standard pitch props
