Here are the basic "plans". Im not much of a plans drawing guy as you can tell, but all the basic info is there, though its not to scale.
I'll post some more build pics in a few...

Edit: As requested Ive added the plans drawn by Skylar. They are metric so deal with it 
If any new plans are posted I'll put a copy here.
I recommend you build the standard sized one to begin with. It is the easiest to fly and is most tolerant of using slightly heavy gear. The Mini is the most dificult to fly and is more sensitive to exta weight. The Mini is NOT the best bet for indoor flying. The standard sized one will fly much slower.
One set of plans is for the full size version and the other is for an 85% sized version.
As of July 2008 my current favorite is a Mini-Capricorn that is sized at about 60% of the full sized version. (edit: I've changed my mind - the mega version is now my favorite - at least for now!) Details are further along in the thread starting about post 405. I added another video of the mini version above. Its a totally different bird than the larger one.

Here are the specific dimension of the mini as shown in post 441.
I just got home - the main panels are 5.5" wide. The length from hinge line to the tip of the extended nose is 23". The nose is swept back at a 45 deg angle.
The elevons are 4" wide at the shortest point extending to 6" at the swept tips. The inner pair are 4" and the outer pair sweep from 4" to 6".
The rudder is about 10" tall and about 14" long. That is measured from about 1.5" below the center 'V' to the top of the rudder and from the forward most point to the tip of the swept point. The hinge point is about in line with the 4" wide elevons so you can get a minimum 45 deg throws. I like 60 deg better 
Those dimensions of the movable surfaces are not critical - but dont skimp
The sponsins are 11" long, 2.5" tall, 1.5" wide.
Bottom brace acroiss the center V is 4" wide and I made it from 3mm.
By the way - Skylar says they call this the flying 'wobbleU' in Africa, so I changed the file names
For those of you just starting - 97% of what you need to know is in the first 40 posts or so. If you read thru post 60 you will have 99.99% of the important details.
You dont really
need to read the whole thread - BUT along the way, there are many small items explained in more detail, lots more pictures, many questions asked and answered and then answered with a different option.
There are also a great many modifications, options and variations discussed as well as pictures of how other folks have done theirs. There is even a VT version by Leadfeather.
I think there is some good info that is worth taking the time to search out.
New addition:
Lee has done a great tutorial with tons of pics and explanations on his thread. He has - like everyone else so far - done things a bit differently on some of the details. Its well worth looking through!
