Also, getting the proper weight load on the strafe wheel of an H drive isn't as easy as putting all of the wheels in the same plane. If making a(other)n H drive, I would put springs or a piston to push the strafe wheel down so that the load on the strafe wheel could be adjusted according to driving needs.
While it is certainly a good option, in my team's experience, a suspension is not necessary in order for a H-drive to perform well. We used a statically mounted slide wheel this year. Once the drive train was assembled, we shimmed the wheel down until we were satisfied. Combined with a somewhat floppy chassis, this served us very well over the course of four events; it was very simple and we only had to adjust the shims once due to wearing of the slide wheel.
