So my rustler XL was running and all of a sudden stopped. The wheels turn when I turn the knob, but thats all I get. I figured the brushed motor went out so I replaced it, and still nothing. Any suggestiongs to get it going again? I'm thinking about getting a brushless system, and if this problem i'm having is because the ECS is bad then I'll just go ahead and get it, just need some advice from more experienced owners.
