I've got the 1/10 Grave Digger and last summer I upgraded from brushed to Velineon brushless.Well a few days ago I was driving it and it quit moving. You can hear the motor whine but it wont move. I took the motor out and I tried revving the motor itself and it has very little power. I'm using NiMh batteries only and I had only been using it for 5-10 minutes, maybe. What happened? I know Traxxas sells a rebuild kit for this motor, so could rebuilding the motor fix it? I really really do not want to send it in to Traxxas. Thanks!
