Agreed, haha.
I also just noticed in the pic that the red battery lead is exposed. It might be a good idea to add another layer of heatshrink to it so that it won't short against the chassis (make sure to cut a hole over the heatsink if you do, so that heat can escape). If you do put some heatshrink on it, make sure that the red jumper located under the red wire is somewhat easily accesible. IIRC, the red jumper is used to program the ESC (taking it off enables programming mode.. I think).

Also, do you know what shock towers those are? I've been looking for something like those...

Edit: if you haven't seen this thread, it'd be a good idea to look, as it details step by step how to progrm your BK esc, as it is a bit complicated.
