UKMIL did just release the Gazelle AH1.Yes a 139. And a gazzelle
UKMIL did just release the Gazelle AH1.
Being a Sikorsky guy, my vote would be S-92/CH-148 also, but of the listed 2, picking the AW139 or newer 189.
To go with jeansy's retro but still a workhorse, S-61T.
the next question should be, who would you like to see develop it?
First choice: Cera Simulations (creators of the Bell 212, 412, 222, and upcoming Sikorsky UH-60)
Second choice: If Mi-8, an independent Russian developer...
Third: Milviz independent of Nemeth.
Fourth: Nemeth stuff has been released kind of buggy lately, but they seem to be the only other major helicopter dev house that puts some sort of emphasis on realism/systems.
