I can't remember who had the 6-razors-on-a-hex-plate idea [possibly S_M], but kudos to them.
I think SM is a pretty cool guy, eh builds unicycle-bots and doesn't afraid of anything
FOTEPX I believe had the hex plate idea.
MMR Rules - Bot must have atleast 2 Wheels
stick the second wheel on the polycarb extender instead of on a motor.
