Gary, thanks for the very informative "follow along" posts. I too have a DFW and plan to attempt the same scheme. You've given me some good ideas about weathering as well as another possibility for turnbuckles. I think I'll give RB's etched buckles a try. I've been making my own with brass tube sections and while they work fine and, with monofilament, can actually serve as a real turnbuckle when structural forces are needed in the rigging, I think with Wingnut Wings' fit and rigidity of the struts and wings, they are usually not needed. I plan to use EZ Line and I suspect with RB's turnbuckles this will look fine and make the rigging process a bit easier.
About your representation of the spars and ribs on the wings, did you seek to represent the upper structures as being a light CDL being pressed upwards against the fabric which as been worn a bit and showing thorugh the paint? The undersurfaces of the wings and tail planes look very realistic as "shadows" on the fabric. I like the upper surfaces effects very much.
This build has been a fine tutorial in attention to details for me, an area that I often struggle with.
Best regards,
