shorting out?

Where to start! first off your using a measely 1/10 esc to push a Monster truck. Second is that 3s is really not enough to push around that heavy monster truck. Third your servo may be pulling way to much current because the bec in the speed control was only meant for use in 1/10 scale and that servo on a MT is gonna pull more current than a servo in a 1/10 stdium truck will. If you can spend the money on a killer servo then why not spend some on a proper esc?
