I have just checked the proportions of the model. They are wrong.
This is a quick overlay of orthographic renderings of the original CG model:

You can clearly see that the outlines do not match.
You should not start unfolding before making some changes to the mesh.

It is not the same model! Just a variation that is buildable with ( cockpit in the works ... DROP-IN as in the TV show) and fold up workable landing gear and such! This one is buildable!
You are comparing to this one...SAAB Wildcard version...
it is still off a slight bit.
as the intakes are not slanted as far as the original, and the fuselage is a bit narrow but matches your comparison fairly well. Trouble with the real version ( I know we want the REAL DEAL) it is UGLY! and almost impossible to make buildable. Was looking at references and these lines are Nasty for paper!
and the landing gear! acckkk!!
That rear gear will NEVER WORK!
Got some of the original concept sketches...and the mesh in the TV show is fairly close.. but not the TV full scale version ..they goofed on a lot of things..
... Hard to tell but in this screen grab looks like the intake is flattened more like my version
... this screen grab view shows the curves of the rear sections that will play hell with a paper version...
So all and all I'll chalk this one up to an exercise and file it away to the Maybe Someday If I GET AROUND TO IT FOLDER...
