It sucks...
It's the only game in town for a Sturmovik in 48th (unless you're into vacs & resin) and it would be kinda hard to beat this kit. I can only see one manufacturer doing a "better" job on an IL-2 and that would be Tamiya. But seeing as that won't happen in our lifetime...
Anyhoo, it has a few minor fit problems, but I've yet to come across the perfect-fitting kit.
If you're thinking about buying one, or building one, go for it.
Fade to Black...
