We'll call this one The Geeko, since it was inspired by the Gecko 1 and Jay's RokClod. My first attempt so I tried something simple and proven. Now, I have no axles yet, I am guessing at the wheelbase to be around 16 inches. I had enough fun building this if the links need to be redone, it won't t ake that long. Are these things pretty solid when they are all bolted together? Looks like there may be a lot of side to side motion.
