Greetings,
Making some progress. First, made a decision on which bird to model. Kind of a coin flip, actually, as there's not much difference between the four options on my decals. But I chose this one, simply because I thought the markings were slightly more interesting than the others. It's listed as an A3, though the illustration below is an A4, so I won't mess with modifying the tail.
With fuselage and wings in place, I got ahead of myself, thinking it would be a good time to go ahead and paint the red panel under the cowling and save myself a step in masking. After doing so, I realized I hadn't done much test-fitting beforehand. As beautifully as this kit fits together in general, the joint between the cowling and the fuselage panel wasn't quite perfect and needed a bit of sanding and a spot of filler. So I actually just created an extra painting step and will have to mask it, anyway. Oh well.
With the cowling adjustment out of the way, I masked for priming. Decided to try Silly Putty in the wheel bays and nose, and was pleased with how easily that went. Much neater than my usual wet tissue procedure. I wiped down the plastic with a bit of alcohol to clean, then sprayed Mr. Surfacer 1200, thinned with hardware store lacquer thinner. I mixed it very thin, sprayed at about 12-14 PSI and it went down like glass. I was very, very pleased at the smooth finish, especially as I've been battling airbrush demons my last couple of builds. I'm getting accustomed to the Iwata HP-CS Santa brought me, and I'm really happy with this result.
Like most of my previous Tamiya kits, this one has been just falling together, requiring only a bit of sanding and a couple of tiny spots of filler. That cowling assembly was a bit fussy, as mentioned, and I'm none too thrilled with the molded-on wing cannon and pitot tube. I've already bent one of the cannon and I'll be amazed if the pitot tube survives. I'm tempted to just cut it off now rather than lose it on the floor if and when it breaks off, but I reckon I'll live dangerously and take my chances
