Yeah, its not the mesh (this time at least [&:])

The plastic spur died because of too much motor and some nasty driving, and the kevlar due to a loose slipper that melted up and took the center of the gear out with it. When I get new parts for the slipper I'll run it with another kevlar gear but tighter. Ideally I'd find a steel gear for this thing but they don't seem to exist :/
