Feel free to correct me if im wrong, but thats what we have always done.
the reduction ratios of the NBD modification are 3:1, 4:1, 12:1. (12:1 being the same as the Banebots transmission this year) It would seem a bit fast to direct drive the wheels but wheel size plays a big factor in this (the smaller the wheel the more realistic this becomes), although I wouldn't do it as a cim motor at 3:1 reduction with 6 inch wheels would go ~46.5 ft/sec
