Update! I just want everyone to know what happened. I dont want anyone to think it was only because of the savox servo with the stock Esc. The main culprit was found! I have recently put bead lock wheels on the truck. Everything seemed fine going up and down the street, turns were no problem. I added the savox and went crawling on very tough terrain. Little did I realize I left the longer bolts in the wheels after assembly. When the problem happened I was pinned on the V of a log and branch. Wheels were turned very sharp. The longer bolts dug into the plastic and locked up the front wheels. I repeatedly was trying to get the truck free. This is when it started to smoke and blew out the electronics. The main reason the motor blew was due to the massive strain the bolts that were stuck into the plastic and the stress from being pinned, not the new servo.
