Update - the cockpit and other internals are complete. Some drama -- there was about the same amount of expletives as when I built my D-9 a few models ago. Nothing major, it's just much more fussy than other recent kits. Lots of flash, sculpting, sanding, filling, dry fitting, etc.
I used the Eduard FW 190D-13 detail kit for this build, which is essentially a PE fret with a bunch of doodads that provide more refined versions of components than the base kit. This kit is based on the D-9 kit and was released in 2010. In my view, the "detail kit" brings the level of detail almost to the level of the current generation Eduard FW190A kits initially released in 2016.
The framing around the pilot seat and the harness lugs are nice additions. The cockpit sidewall replacement sections with rivets and framing is not worth the effort. There's a very nice back deck of the cockpit that will go on after the fuselage is buttoned up.
Due to the color mismatch between the new AK Real Colors RLM 66 and the PE instrument panels, I was planning to go with the classic plastic, decals and paint, but it turns out that the plastic parts only reflect the D-9 panels and only the PE had the correct D-13 details. So I used the PE and carefully painted over the base color.
I used Micro Krystal Klear to make the windows for the gages.
The section of the engine rear that can be seen through the landing gear bay was pretty straightforward.
As I mentioned before, I'm going all in on the new AK colors for this build. Even though the tone is more on the gray-olive side rather than gray-blue with RLM 66, it looks pretty snappy. I used lawdog's sequence (from his very helpful tutorial) of cockpit painting this time and it works great - black primer, base colors, detail, gloss, wash, flat, done. The RLM 02 (1941 version) is much more vibrant than the earlier version. It almost looks like US zinc chromate. Looks fine.
I also added the quickboost exhaust stacks since the original kit exhausts don't have the tips hollowed out.
Time to button up the fuselage and start on the wings.
