This is one of my latest creations, the forest-cutter tank. I have information about it but you can see this on my NXTLOG.
What this tank has are one of those exo-force wheels, And 1 pack of tread links. The gearing system is simple yet hard to make sturdy. The gear ratio is the result for speed, which can be fast, I don't know the speed exactly, but it is fast. Now to go see my NXTLOG for other info.
