Rob..........
You are talking about the ESC? If so the dimensions are:
L: 1.79” (45.5mm)
W: 1.44”(36.5mm)
H: 0.85” (21.5mm)
(strait from Castle Creations website) (edit: I believe that those are without fan)

Is this just a matter of everything needing to break in and ill just have to keep an eye on it and tighten it up as I go?
Also the outdrives, they do move freely with resistance, but it almost feels like "sandy" resistance, again is that just a matter of things needing to break in? ie. the washers on the outdrives pressed against the ball bearings?
thanks! Ive never built one from scratch before, so I dont want ot make any wrong assumptions
Yeah, try the bearings but the problem with the outdrives is normal. I have built my diff a few time trying to get rid of the gritty feeling you are talking about but it doesn't go anywhere
Maybe after a while it smoothes out. I tried replacing the gear and the diff balls but neither made a diff-(oh puns)-erence..
As for the transmission case, I don't have that much resistance but I notice a small (less than half a second) change in how long the tires spin freely when I take out the motor and tighten or loosen the screws. I wish I could help you with that problem as that less-than-half-a-second is really annoying me -.-
