APC 9x4.5 Multi-Rotor Propeller

The APC 9x4.5 Multi-Rotor Propeller features a computer-optimized design with a thinner profile and increased bite while reducing noise. Its lightweight molded nylon construction helps reduce rotating mass, while reinforcing fibers support a true, constant pitch at any RPM.

Manufactured using a pultrusion process with 60% fiber-to-resin density, this propeller provides increased strength and stiffness compared with glass-filled nylon. The added stiffness helps with control vibration resonance response, while the thinner cross-section supports weight and aerodynamic efficiency.
