BetaFPV 31mm 2-blade 0.8mm Shaft - White

Lots of pilots have great results with biblade props on high-KV motors, like the Awesome Sauce Motors or the Ludicrous Motors. With less weight for the motor to push around the motors can spin up the props much more quickly and provide faster response to your input. They'll also help the faster motors to stay cooler, extending the lifetime of the motor. 

If you wanna try some out, consider just cutting some blades off an old set of props!

These props are made to fit motors with 0.75-0.8mm shafts.
