GearsOn most bicycles, the gears are made of metal. In fact bicycles that contain composite materials are considered to be high-end products, and are priced accordingly.

The issue of weight in helicopter design is crucial and in the case of HPH - if you can save weight - save it, no questions asked.


This is why the gears we use are made in-house by using a circular carbon fiber lay up, and machining the teeth around the perimeter.
