Sorry for my english, i past lot of time on one post.
Some system are not completed in black shark... as the inertial heat for exemple, or something about the VHF2.
I buy black shark 1 essentialy for the simulation aspect and not for the graphic engine, as lot of player, if they can finish just some system model, i will buy KA-50 with happiest, without that, so dcs a-10 have a good graphic and is good for simulation, and as lot of player, i prefer aircraft, then i am very not sur of my interest about DCS KA-50 2 if it's just that upgrade :)
