...the Futaba S9550 fits without hitting the belt. Then again, it's also used as an aleron servo for planes, so it'd fit just about anywhere.
The graphite reinforced plastic on this car feels like metal! Threads like it too.
Ditto on filing a channel under the belt for clearance when running the diff in the low position. For battery fitment, barely had to square the corners off the rear slot.
The clearance for the "pins" used throughout the car are amazingly well machined. With tolerances this good, who needs bolts and screws?
I removed the bolts that hold the front topdeck in place, but almost couldn't get the topdeck off. That's how tight the tolerances are!
