referb mmm fried

Yea, the short course revo basicly.
When I laid out my system I used the calculators and those said I would be good motor to battery wise with the gearing I am running. Although there could be a difference from whats on paper and whats in real life.

I have another mmm/2200kv combo that I am thinking of putting in, I just what to figure out what was the problem so I don't kill that. I pretty sure I want to run that with 4s packs at minimum. An I on the right track for that setup?
