The links in the first post are working. Some on some of the other pages might have changed though. I switched to a new ISP a couple of months ago, so there shouldn't be any problems now.
Andrew, I have no problem with you posting the plans. I probably should have done them as attachments, but they were being revised for a while, so I was just updating the files on my site with a link to them.
Highfly3D, let me know if you have any questions.
PS, I'll take an Ultimate 10-300 over a Yak 54.
