The Gemfan Flash 7042 Durable 2 Blade (Black) - Set of 4
About this Product
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 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.

They work.
Jason H.Verified buyer
They work and are very durable. Maybe not too of the line but no wobble in the video so that's a plus. Has enough thrust to launch and fly my dolphin like I stole it. What more can you ask for.
Perfect all!! fast shipping!! Thanks

Mixed results
Kyle W.Verified buyer
These added about 1min of flight time to my Chimera7 which is great, but they also added an unacceptable amount of jello. Not sure why, but I removed them after one flight.
Good blades.
Gerard T.Verified buyer
These work well.
Great thrust
Jeffrey Q.Verified buyer
These provide a great amount of thrust and the noise level really isnÛªt too bad. IÛªd recommend to a friend!
