This is the best I can do with selectable Bort numbers for post unification MiG-21. The numbers have to be this large due to the kerning (horizontal spacing) of the Bort numbers being fixed. I can make the font smaller but they would be spaced too far apart and would look strange. Even though they're slightly larger than historical, I think they look pretty good. There are three skins in this series but the combined skins zip file is too large to post in User Files so I am posting them seperately. There is one each in all green camo, tan and green camo and silver paint.
The registration numbers are 22+xx or 24+xx depending on which skin is selected. the "xx" represents the selectable BORT numbers. To select your desired bort number type "00xx" in the tail number window in the skin selection window. So if you want "22+41" on the nose, type in "0041" as your tail number.
They are based on my East German MiG-21 liveries which can be found here:
