A coupla' things I forgot to mention about the model....wing warping will be functional and it's electric (sorry abu) so I can use the Williams Bros. Le Rhones. Lots of wires and struts...over 150 turnbuckles, for example.
The fuselage is framed in the model pretty much like the real thing. All the laser cutting was done by Manzano Laser who have consistently done a great job. Since we are talking about cutting stuff all the fittings are photo-etched and a shot of those is below.
