I shyed away from that design because of my lack of precision in woodworking.  Had 
you not proved it in battle, I also would have worried about a friction drive so 
near the paintball goop zone.

Yeah, in a lower tank, that would be a problem.  
I managed to keep ~4 inches space between the turret base and the bottom of the 
hull.  So an additional 18Ah battery could lay there (once I decide to go 24v ;)
