Query: Just go brushless

these motors burn out way to quickly. Every one I've had in my traxxas rustler burnt out in about one week. lucky for me traxxas gave me 2 replacement motors for free but they didn't last long. I refused to get another brushed motor after the last one burnt out so I ended up buying the brushless system which costs about $160. It is pretty expensive but in the long run your probably better off getting brushless because it will be cheaper than having to replace the brushed motor every week.
