I am running on 3S and keep stripping rear wheels. I stripped a factory wheel fairly quick(maybe a week or so) so I bought a set of trenchers on Desperado wheels. Ok, this weekend was the first time out using them and after about 10-15 minutes I stripped the right rear wheel. The nut did not back off, the wheel stripped out and came of the vehicle with the nut still tight. I was in both grass and dry dirt when this happened. No jumps involved. What am I doing wrong for this to happen or should I use a different setup?
