XXX-CR

[GAZ]

Been having some problems with my xxx-cr used it twice now and i just seem to be cooking motors, so bad that one of the brush shunts desoldered itself. I'm guessing it's down to the copper shims in the diffs giving a litle bit to much slip, I'm going to try it next week without them and just shim the diff on the outdrives.
Has anyone else had any problems with this?
