Product Description
Contra Rotating Propeller Drive System for RC F3A Plane Pattern Competition
The motor shaft and the middle one are made of titanium alloy.
The lightweight is better for F3A flight.
The plastic gear is strong enough which hardened on the surface.
We have tested it with this motor, it saves electricity.
And the gear material we use oily plastic, which is wear-resistant and quiet
