9x3.7SF Slow Flyer 3D Indoor Propeller

The APC 9x3.7SF is a slow flyer propeller designed for 3D and indoor fixed-wing RC aircraft. The SF designation indicates a pitch and blade profile optimized for low-speed, high-efficiency flight rather than speed runs, making it well suited for lightweight parkflyers and indoor models. At 9 inches in diameter with a 3.7-inch pitch, it delivers the gentle thrust characteristics these flying styles require. 9 inch diameter, 3.7 inch pitch
