Gemfan Flash Propellers have been specifically designed for high-speed racing. The inverse tip design helps to reduce blade tip vortex and the light weight of the propeller means it has a smaller moment of inertia and fast response time.

Gemfan Flash 2540 Durable 3 Blade

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.

I use these props on the betafpv HX 100 SE frame with 1102 motors in the 9000 to 10000 kv range. They don’t spin up as fast as bi blades, but they are smoother, quieter and have better bite in the turns. They weigh about twice what a set of bi blades would weigh, but for my style of flying, they are worth the weight.
