Operating principle and aerodynamics

Gemfan 51377 propellers convert the rotation of a powerful motor into lift and thrust. The 5" diameter is the standard for racing and freestyle drones, providing the perfect balance between maneuverability and stability. The 3.1-inch pitch is selected to create optimal traction when working with high-speed 2207 2100KV motors.

The three-blade design allows for more efficient use of engine power, especially during sudden acceleration and braking. Rigid polycarbonate maintains blade geometry at high speeds, which is critical for predictable drone behavior. Wide blades capture more air, providing powerful thrust and excellent stability when performing complex maneuvers.

Specifications and Applications

These propellers are an excellent choice for 5" racing drones, freestyle quads and light cargo platforms. They are ideally combined with the 2207 2100KV motors on 4S and 6S batteries, providing excellent responsiveness and long flight time. Proper operation requires the installation of both left- and right-hand rotation (CW/CCW) propellers. It is recommended to purchase sets of 4 propellers to complete the drone.
