T4 CF Battery Strap for the CRT.5.

Nice work. I wanted to do the same thing with my hard case batts, but they stuck too far over the side of the car for my liking. Consider moving your ESC to the front of the car and the batt to the back. You could route the wires along the top of the batt strap. This would give you a better weight bias for handling.
