I'm running a stock 4x4 and the ESC has burnt out twice now. I got it back in February and after about 8 packs the truck died. It just stopped running. No power, no lights. Nothing. I checked the temps of the ESC and motor and neither one was above 120 degrees. I shipped it off to Traxxas and they sent me a new one. Cool, but I was out of commission for two weeks. I thought I'd get an ESC fan to try and help with temps. It ran fine for a few more packs then it died again. This time they wanted me to send in both the
ESC and motor. (another two week turn around)
This last time it happened aftert 10 minutes into a 3000mah battery the truck just stopped. The ESC had that wonderful smell of burnt electronics. I contacted traxxas again and while trouble shooting with them I noticed the motor getting HOT. All I did was plug in the battery. Again it wont turn on and no throttle was applied. I hope they can sort it out this time. I live in San Antonio and if it overheats when it's only 70 degrees outside, I'll never be able to drive it this summer. It's not like I'm pushing it hard. Just some impromptu races with buddies on dirt.
I tried searching forums and google and I can't believe no one else has similar problems, so I figured I'd post.
