That is a very nice wiring job, all the wires made the right length. I agree that rotating the esc 180 deg would be better, it would make the wires shorter. Attaching the battery + wire closer to the esc would lessen the effect of the wires on the read pod movement. There are other solutions like the low-centered wiring we use, but this is a fine job, it's cleaner than 99% of the cars out there (most pros cars don't look this good)

BTW do you have a parts source for that car? I have one but don't race it because I can't even get wheels!
