That's a Ka-52, not a Ka-50-2... and it's in FSDS as i alredy have it for FS2000
The Ka-50-2 is a custom-build one for turkey, the americans aren't happy with that as they liked them to buy the AH-64
The Ka-50-2 has a in-line seat config, while they sit side-to-side in the Ka-52

Another picture, definetly no Ka-52
