330 tends to mount their gearboxes aft of center, then do a chain run to the center and another to the back wheel. Then another chain is run from the center to the front. This is best seen in http://www.chiefdelphi.com/media/img...05e54dc2_l.jpg, which is of our 2007 practice robot. (Also used in 2005 and I think 2008.)

We've also put it above the center wheel and run one chain to the center and back wheels and another to the center and front wheels on our 2006 robot: http://www.chiefdelphi.com/media/img...00d247fd_l.jpg
