Gemfan Hurricane Durable 51477 3-Blade Propeller (Set of 4)

The Gemfan Hurricane DP 51477 3-Blade has been designed as a high-speed propeller. These props have a diameter of 5.1″, 4.77″ pitch, 5mm shaft hole, and only weighs 4.15g! Gemfan 51477 3-blade Hurricane Propellers have been specifically designed for high-speed racing yet can also suit a long-range rig looking for efficiency and increasing flight times. The inverse tip design helps to reduce blade tip vortex and the lightweight of the propeller means it has a smaller moment of inertia and fast response time. Gemfan designers use CATIA modeling software and Ansys Fluent to design their Hurricane propeller airfoils and blade style. Combining the most effective airfoils with different motors to get the most iterations on their design. Testing factors such as surface pressure, airfoil optimization, lift force, resistance, and torque have resulted in the Flash series – made just for racing. Choose a color!
