[GUI]

You might want to use smaller wheels to help keep your cg down low. Since there aren't ramps to climb in this game, big wheels don't really have an advantage. You can get the same speed and torque with any wheel size by changing the gear/chain reduction. Smaller wheels also leave more room on the bot for other things, like a giant game piece. We're planning on 6" wheels, maybe 4" on the front.
