Hmmm....
Well, that's one of DML's later reissues of one of the old Trimaster kits. The vast majority of the parts can be found in any of the variants released by either TM or DML. Perhaps that's the problem, old beat-up molds, and the plastic problem. Could also be the injection molding process they use. Cooling problems? I dunno fersher. Toad would know about all that stuff better than I. Toad, you out there?
Another thing I've thought of, the single seat 262 kits had their fuselage halves molded in two parts so as to provide flexibility in producing several variants. When swapping the mold pieces back and forth, the resulting pieces are not always perfectly formed or aligned. (Remember the AMT P-40's? UGLY!) This could be one additional problem in your kit.
Anyhoo, the 262 that I've started is an original DML release. And maybe that's why I've had few problems. Dunno what more to say!
When I heard of the new Tamiya kits I was contemplating replacing most of my DML 262's, but that's kinda impractical. (Who am I gonna find to buy a dozen old DML kits when there's nicer Tamiya kits available?
) Besides, many of the variants aren't available from Tamiya. (Yet!)
It's a good thing I plan on doing some abandoned and beat-to-hell Luftwaffe aircraft dioramas! These might just be perfect for that job!
