Hey TimV, if you don't have a hobby vise, use some good servo tape (Parma makes the best) clean your work area with some motor spray where you plan to put the ESC, then put some motor spray on a paper towel and clean the side opposite the wires, apply the servo tape, and it should be solid. I used this when I rewired my GTS and it worked great, other than I am crappy at soldering and melted the case a little, oops
