VinceVerified owneron Mugen Seiki Plastic Mod1 Spur Gear (46T)

A very good spur gear, but it will shred like tissue paper if you are not careful. I lost two before I figured out what the problem was. It was loose screws on the under side of the motor mount. That allowed a little flex in the motor mount and would zap the spur gear on any kind of hard landing or impact. A little Threadlock might not be enough. I used teflon tape and Threadlock. Problem disappeared.
