8.5" square. Frog base. Model is approximately 3" long, 4" wide. This isn't a very good shot of it, the engines are supposed to be round. Designing the engines with some sense of volume made me happy.
I also like how the wings are 'swept forward' - the leading edge is perpendicular to the body line, instead of trailing away. Scale is still pretty off.
This one is a pretty easy model. I've been making frog-base X-wings since I saw the film, but only recently did I realize the advantage of actually MISSING the vertex. In my opinion, the nose of the fighter looks better with the folds not coming to a single tapered point.
That, coupled with the already-mentioned perpendicular sweep of the wing's leading edge and the near-cylindrical shape of the engines make this one new enough to feel good sharing.
For its "other half", I created an origami T.I.E. Fighter ([link]
