I've tried different batteries and even put in a tx out of another buggy that I know for sure that it works. I double checked the motor wires and they're plugged in properly. Any body have any ideas I really don't want to send it back to HPI. Another thing when I first turn on the switch the fan doesn't come on. I checked it and it spins freely.
Check the motor plugs again...on the ESC and the motor...sometimes they can get gummed up and it doesn't take that much (almost like a dark tarnishing on the gold plating) and prevent the ESC from detecting the motor and/or causing a short/stutter while running. I had this happen before and all I did was scrape away the buildup and it is good now. Not sure what caused it...neither was Castle. Something probably got in there and caused some kind of reaction under all that voltage...now I just keep an eye on them. Hasn't happened since. Hopefully that's all it is.
