APC Props Speed 400 5.25 x 4.75 RC Aircraft Propeller - APC053475E

The APC Props Speed 400 propeller in 5.25 x 4.75 pitch (style code APC053475E) is an electric-specific fixed wing propeller designed for use with Speed 400 class brushed and brushless motors in RC aircraft. APC Props are a widely trusted name in the RC plane propeller market, known for consistent balance and accurate pitch geometry straight out of the packet. The 5.25-inch diameter and 4.75-inch pitch combination suits lighter sport and park flyer fixed wing models powered by small electric motors, where efficient thrust at moderate RPM matters most.
