Our electronics looks similar ( we didnt do as neat of a job with the holes ) but its in 3 layers. RC, powerblock, and main breaker on top, then 5 victors, our
ground stud** and the big brass 40 amp fuse block on the second layer, and the third layer has 4 spikes, the main fuse block, and the 7.2 volt battery. the whole thing is like 12x10x11", which is less then a sqare foot. however the battery and compresser got delegated to the chasies team, so there not my problem

**ground stud. when i say ground stud, i meen a piece of angle aluminum that i drilled a bunch of holes in. is the "ground stud" an essental piece? it would be a pain to redo it now, and i see no added electrical benifit. actualy the system i have now can deffenetly carry the current.
