Funny you ask about this now as i have just done this earlier today But i am using a Mamba Monster-ESC, if i routed the wire under the batterytray and over the "bridge" as described in the manual it got too short, so i routed it under the tray and through the front chassi brace (through because it is aluminium, but i guess you can go under if you've got the plastic one), and into the radiobox. I gained a good 2-2,5 inches by doing this. My camera is getting some milliamperes now but i will take some pics tomorrow of the wiring when it is fully charged.
