Hi John,

Ben beat me to it
But yeah, the main webpage hosting them has been down for a while now, and it's also been a while since I spoke to the guy hosting them so I don't know if that webpage will be back up at any point but they seem to be all right on the Photobucket page so I'll just leave that as the main source of them now, especially as they're too big for an email attachment.

So for clarification for anyone looking for these build guides, just direct them to the Photobucket link: http://s31.photobucket.com/albums/c367/ ... 0articles/

Hope they're of use to you John
Also check out the Riobotz tutorial booklet (360-odd pages); a lot of information but very useful and more up-to-date than the Rex's Robot Challenge guides: http://www.riobotz.com.br/en/tutorial.html
