I'd imagine the bulk of it would be the main cockpit of the jet, the midsection the gunner's seat moves down, and the gunner's station. A cockpit big enough to fit 3 figures, lights, sounds, and a tail section that can open up and convert into the cannon Sam mans. The wings would probably be separate snap-in pieces that make the jet even larger, but they have to fold up for storage/landing like in the film. http://images.wikia.com/tron/images/4/4d/1292542854.jpg Considering the box dimensions (12 inches length x 8.5 inches width x 4.5 inches height) are around the size of a sheet of paper, it seems big enough for the bulk of the jet (though size might be compromised). Each wing looks big (as long as the jet's body). I'd imagine somewhere around 12-14.7 inches (if they pack them in the box diagonally), the same could be said for the jet body if they pack that diagonally. So I figure it could be almost 3 feet or longer, plus however long the tail makes it. That's gonna be a big jet.
