Extreme articulation is awesome!... high ground clearance with the frame design, low center of gravity and acts, but doesn't, like it has a ujoint in the middle to twist the front and rear independently.
My rockcrawler does really good like that one, but definitely not quite as well.
Maybe we need to have a rock crawling thread to post all cool vids and pics like this one?... and for mud racing?...and boats? Whohoo!!
