How to stop wheels spinning off their output shafts and Brushless drive

[Ellis]

I wouldn't use much on the wheel's threads (if any) as if the gearbox goes it'll be a massive struggle to remove it, but the reverse threaded bolt could benefit from some. The suggestion above of sturdy enough washers, so tightening up doesn't flex them, is a good one.

edit: although 6 is overkill lol
