Well well, time for another update after quite a while.
In addition to removing the umbrella mounts of the trop version from the left fuselage half, the two filler hatches of the MW-50 boost system had to be filled, as this is to be a G-6, not a G-14. (and as this is the G-14 boxing I have, it of course isn't mentioned in the instructions)

The cockpit's done and the build's ready for closing the fuselage:




As the PE fret supplied in the Aires cockpit set lacked the two prominent handles on the instrument panel, I resorted to slightly modified bomb rack pins from Eduard's Hellcat. Another thing missing was the magneto selector switch knob, which I replicated with a tiny ball of milliput. The gunsight is from Quickboost, as the cockpit set supplied a Revi 12.
Here's a better pic of the sight:

The colored sun shade glass was tinted with now discontinued Citadell brown ink.
A bit strangely, the acetate film going behind the main instrument panel covereted only half of the PE panel (where the gauges are located). To get rid of the resulting step in the back, I glued in a second piece of film from some left-over pieces I had in my spares box.

I did some decal shopping last week and now I got the full stencils I was longing for:

Looks like I can also use the national markings as well.
