The Ukrainian firm offering models of quite rare types. the box contents look quite decent. Unfortunately these two Yaks aren't the best kits. Contrary to that the 1/48 Beriev Be-4 (KOR-2) no.48003 kit was found a very good on. However the kits are quite expensive here in Poland.
Any model doesn't look too bad. Just a matter of a modeller and his will to assemble a kit. Certainly the skills are also important but where there's a will there's a way. Right?
Regarding these models but of the 1/72 scale .. the Amodel offers them ...
