That's a pretty serious drive base! I guess the offseason is the perfect time to max out a drive train for a team that has that itch.

You've listed just two speeds. Is the gearing from the 6" to 4" wheels setup to keep the two types of wheels at the same speed? If not, then you really have a four speed drive.

In my mind, one of the benefits of octocanum is that you don't need shifters. It's already providing the benefits of a two speed if you gear the Colson wheels slower than the mecanums.
