I cant help but think of how much fun these guys might be if you could run say 100 or so at the same time. Just picture it now, Mini tank battles in a dirt lot with a crowd of people going crazy off to the side controling the whole mess.
Take it a step further and with the help of a Laptop and a highly customized set of tanks you command entire platoons of tanks with the click of a mouse button.
Dang it now I'm going to have to figure out how to get a micro RF system in these tanks and rig that to my laptop for a little table top StarCraft action.
