I was driving my Traxxas rally today and everything was fine, until the low voltage protection came on (I used a lipo battery)after just 5-7 minutes of driving. So I thought, okey the battery was not fully charged but when I put a new charged battery in it, it barely moved... everything else works, steering, forward/reverse all works fine. its just that the motor wont rev, even when I give ful throttle. it is like its running on 1/6 throtthle.
so does anyone know where the problem might be ?
