9T polymer pinions, for 1mm shaft

45   |  

Acetal polymer pinions, suitable for most gear drives use in micro planes, helis and multirotors.

Acetal polymer, also known as Polyoxymethylene, is sold under many different brand names, such as Delrin. It is a very tough plastic, and used in many wear parts throughout the industry. 

Acetal pinions run quieter than brass, show less wear, provide less stress to the spur gear, and are easy to mount/remove by hand.

Awesome!

These are great, much more sturdy than the stock syma x5c/x5c-1 pinions. Also, much cheaper than buying syma replacement pinions from China off eBay.
