I still have some fixes to do with the yellow one but blue squadron in on the air, WIP. I want to do several, may be 9, to play in campaign or PCWG. So, it's not historical accurate because I don't know any VVS documentation with as many planes of the same squadron.
I'm looking for a russian cursive font but i did not find it yet.
They look fantastic, and its not always going to be 100% exact, quite often I have found due to new documentation & photo's, that things change. I would say semi-historical, until new evidence shows up. Regardless, & welcome to A&A mate. Well deserved.
I don't know how it works in newer versions of PS, but in the past I've written Russian text in MS Word by using the the special character option and then copied and pasted the text from Word into the PS text tool. Though one problem is, that not all PS fonts support Cyrillic letters. After selecting font, size and color of your Russian text, you can convert the text layer into raster format if further editing with other PS tools is necessary.
