I had patterns for these LONG before I knew who Turbolabo was.
Curse the internet for not providing sources for these, and just the raw.
IF you happen to get an SD model of his, and no instructions, he almost always has a section about his build process in his blog.
Here's the blog page for his design and build of the HI-V Gundam SD
I copy that link and past it into babelfish.yahoo.com to translate from japanese to english. Its not terribly precise, but its useful, and usually understandable.
He's got a LOT of SD's in here. I dont know if I have downloaded them all yet.
Click on a picture, you see the full size pic. (for pattern pics, its the pattern you save.)
Clicking on "seeing more" takes you to the blog post where he builds it.
Pretty awesome site.
