i have a similar problem. i just purchased an arrma granite 2wd brushed yesterday november 26,2016. i charged the battery at the hobby shop. went home drove it. i hit the curb and i checked the truck, the front left side shock came apart at the top. then i kept running it and it suddenly stopped. i picked it up, turned it off and then on again and it continued running for about 10 seconds then it died again. i picked it up and did the same thing again, turned it off then on but this time i held the truck up and accelerated it and the rear wheels responded. it was running. as soon as i put it on the ground it lasted 10 seconds and then died. i noticed the wheels would turn but the truck would not accelerate at all. what could it be??
oh another thing. i charged it for about 3 hours and the battery never got warm. then i charged it a couple more hours and it would not get warm... is that normal, that the battery does not get warm??
