I am new to the site and just got a used crawler that I think is a stampede based crawler and I am having problems with the xl5 esc. It was fine at first but now it turns fine but when I try to move forward or reverse the green light turns off and it wont move. I reprogrammed the esc for my remote and it will work for about 30 seconds and then do the same thing again. I thought it could be bad connections but i checked all the wiring and it looks fine. Any ideas?
