APC Props Slow Fly 10x3.8 RC Aircraft Propeller - APC10038SF

The APC Props 10x3.8 Slow Fly propeller (APC10038SF) is a fixed-pitch RC aircraft propeller designed specifically for slow-flyer and park flyer electric setups where high thrust at low airspeeds is the priority. APC's Slow Fly series is engineered with a higher pitch-to-diameter ratio optimised for direct-drive brushless motors running at lower RPM, making it a popular choice for foam electric fixed-wing models that fly at gentle, scale-like speeds. At 10 inches in diameter with a 3.8-inch pitch, this prop sits in a size range commonly used on trainer-style aircraft, warbirds, and larger park flyers.
