I think alot of the reason they weren't used for long was the dificulty in maintaining them.
They took a lot of effort and that isn't readily givin.
They are fantastic little vehicles, and I've seen them put Hummers and the rest to shame. A special built vehicle can out do them, sure, but out of the box there hard to beat.
You'll have to ask the webmaster over there if you can post the vids. I doubt it, they are for sale.... I have them all and they are real good quality and cheap. Russ Blackburn does a great job on the site.
