Welcome to the forum and the firestorm. Your truck is fine, nothing to get upset about. The two wires needed to be reversed. The reverse mode has a fraction of the power of forward mode. With sensorless motors the three stages are arbitrarily set up in the ESC and hence sometimes wiring needing to be switched. I have two castle ESCs that are that way and the rest are not.
Merry days to all in the forum. I've got a durango DEST 210 now as a track truck and the storm stays a street vehicle. The durangos are nice and worth checking out.
