Gemfan F4019 4 Inch Floppy Proppy Propellers have been for efficient storage and speed-driven racing. Not only are the folding styles great for more agile freestyle moves but they also allow the quad to be packaged away more easily.
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 Flash series - made just for racing.
