Wow. Once you get this together, I don't think you'll be taking it apart to build the AAT. This is easily the nicest DD made by anyone, and I believe it to be the best EpI toy made. Not only is the finished model huge, but it actually rolls up and will then expand open into the menacing droid with a little work. Be sure to note the leaflet in the instructions that will help to fix an oversight. A truly incredible piece of engineering and design.
