This is a very welcome addition to my aircraft collection, and in fact my first Russian one. According to Yori over at http://yori-hobby.blogspot.com/ the kit itself dates from the Cold War era and was one of a handful available to collectors behind the Iron Curtain at this time. I am now inspired to find a ground attack variety of some description, perhaps an Il2.
The engineering was quite good, except there was a fault with the canopy which left quite a gap between itself and the top of the fuselage; no worries a bit of PVA glue soon fixed that. The painting was cursory as this was needed for a game, but I intend to touch it up a bit still. I have this thing about all my aircraft having pilot figures at the controls, and so quite a few of my models have pilots made from spare German motorcycle riders because several of them are wearing goggles, but I'm starting to run out of these and may just have to acquire a box of commercial ones, I think Revell might make some, but will check PSR and see what is available.
