Gemfan designers use CATIA modeling software and Ansys Fluent to design their Flash 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 Gemfan Flash series - made just for racing.
