Once I get the new cockpit seat panel cut out, I will lay it over the previous (good) panel, and see what needs to change. Looking at the new dimensional drawing, I expect the differences to be minimal.
Here is a picture of my collection of flat panel parts, stashed away in the downstairs rec room for safekeeping.
The cockpit seat panel in the bag above, is my last flat panel part. Everything else is done, sans filling in exposed panel edges with putty (a not-very-fun job, but I will be doing it soon).
I think I should be feeling pretty good at this point (cue James Brown lyrics). I sure hope that this building strategy I'm following (build all small parts and flat panels first) works out.
