I put the replacement ESC in a ran a few minutes on the street in front of the house and all was good. I went to the sand dunes this weekend and took the Slash. It was a blast for the first pack, I ran it until the LVC kicked in. I recharged the pack and went to run it again, but it seems to lose power and cut out occassionally now. I also noticed that the fan runs all the time, even when it's stone cold. As soon as I turn it on, the fans is running constantly. Is this one hosed too???
