thebigo-I was not accusing you of being lazy or accusing you of anything. I was just trying to get the point across that more people need to learn how to work on there models. Sounds like you know the steps to take. Locating the problem is 1st.. Repairing the esc is probably not gonna happen. If you accidently stripped a wire, you may have shorted the esc and ruined it. I would test the replaced track motor to see if it runs in both directions and if so I would hook the esc to a known power source and a good motor and see if it would work. If it does you probably just have some wires wrong but my guess is the problem is with the esc's. A systematic approach to trouble-shooting is very crucial to quickly finding problems. Good Luck
