How can I make an articulating rock crawler?

ok i have been thinking about this for quite a while now. so what my plans are is i have is an old articulating and i want to make it into a rockcrawler. let me know whhat ya think i will post some pics of it tomorow or somthing.

are you talking a "bend in the middle " or one with lots of wheel travel?

like one that bends in the middle

ill get some pics of it up hear tomorow maby if i can

friend of mine had one once it was great for going around trees but would get stuck on a dog turd when you turned so if you can make it turn in the middle and pivit side to side then think it might work

just my two sents

yeah i was thinking of makeing ot into a crawler but im kinda short on money at the time
