Thanks, man.. I finished up the nacelles today, I cut off the "display" engine nacelle on the left boom just forward of the cowl flaps and vacuformed another cowl from the right-side cowling... Can't stand the "one open, one closed" configuration of the kit as is... I ground down the cowl-flaps to a taper more or less the same as the right boom's as well, to make the new cowling fit.
I also cut out the carb and oil cooler intakes from the wing's leadin'-edges and installed some individual intake vanes, six in the outboard, three in the inboard intake and painted them green zinc-chromate... Speakin' of which, I was lookin' over the Black Widow Group build, I noticed that most everyone had the interiors in overall green zinc-chromate, but I didn't have a warm-fuzzy about that, so I checked my reference (Wings of Fame, volume 15) and it showed several birds with the green primer in the wheel-wells and such, but a mix of black sidewalls and green zinc-chromate floors & seats in the cockpits of the black-painted Widows... I felt this was more accurate, since US nightfighter crews usually had the cockpits re-painted in black or dark gray after they reached operational units, to cut down on reflections on the interior of the canopy and windscreen.
I also considered cutting out the screens on the bottom of the nacelles and replacing them with mesh, but decided against it, since I didn't have a good look at them on the real bird..
Anyway, here it is with the sub-assemblies put in place (not glued) and I'll start adding wieght to get it to sit on it's nose-gear tonight. It should be ready for paint by Saturday if I get all the sanding and filling done, although I'll likely hold off for a bit longer. Once it's ready for paint, I'll start construction on the diorama base... I haven't yet decided on ETO or PTO though, nor if I'll do a historical P-61 or make "me" the "pilot" and do a custom nose-art of some kind (I do this a LOT). There's just something about seeing MY name on the canopy rail of a bird I like, LOL... If I win the Powerball, I'll do it on a real Warbird, for sure, lol...
