These break easily on the Outcast. Have gone through 3 and have 2 more on backorder. I even set the ESC to a softer start and I broke one. May consider trying the 13 tooth gear and hope it has better material and design strength.

It is made from cheap steel. Easy breakable. Two runs on local track.
