My Mini Revo is about two weeks old and I run 2 cell lipo in parallel. It was running fine one day and then it stopped mid-way through a battery. Then the car would not turn on anymore.
When I press the button on the ESC, it would just blink red very faintly. I charged the batteries and let it cool down etc, etc and nothing changed. I emailed Traxxas support and we finally agreed to an RMA number to have the ESC shipped back.
But when I took the ESC off, I tried it in another car and it worked. The receiver worked too. As it turns out, my servo was dead and whenever I plugged it into the receiver, the receiver and ESC would die. So I think the servo is shorted and is the culprit.
I just wanted to give everyone the heads up since this was a tricky one for me and could have wasted a lot of time if I sent the ESC in.
