    I have a big one already built (Well compared with the others I've built) But the format that my camera films in doesn't seem to work with WMM. I'm trying to get it fixed.

    Well for first its not a dumb question.
    I get them from sets I got I while back (6-7 Years ago) And you can get them on Ebay. K'nex dont sell the original K'nex any more the only sell KidK'nex and Micro K'nex so the only place you could find them now is Ebay

    Yes you only need 4 cog's but I put more in to make it more stable.

    Videos? Yes
    Instructions? No, the reason is beacue the two new videos i will post in 2010 they have already been destoryed to make a newer one which is under construction :)
