Pretty much the car always wants to go left. The servo seems in a perpetual state of going left and dosent want to go right ever. When I take apart the servo the little servo motor always spins one way once the remote is turned on and when I try to turn left with the remote the servo motor stops. I checked the crystal, installed fresh batteries and checked all the solder points on the esc and stuff like that. I did resolder a thicker gauge wire on where the receiver wire is that goes to the antenna. So now their is the stock wire and a thicker wire there. Would that mess things up? Any clues as to what causes my car to turn only one way?
