APC 7x4 SF Prop
by APC

The APC 7x4 Slow Flyer Propeller is designed for lightweight, high-efficiency performance. Manufactured with a pultrusion process, it features a high fiber-to-resin ratio for superior strength and stiffness compared to glass-filled nylon. This minimizes vibration resonance and enhances aerodynamic efficiency. With a computer-optimized design, it delivers a thinner profile, increased thrust, and reduced noise. The molded nylon construction keeps it lightweight, extending motor life and improving output.
