Thanks for the really helpful replies! =)
A little background: I'm slightly handicapped on one side, so I can't operate rudder pedals or a full hotas effectively (I have the pretty common T16000M in the DCS-Community). So the Stick gets stuffed to the limit with the essential functions and the throttle with the rest for the convenience, but a simultaneous operation of both would not ideal for a stable helicopter flight. :D
Sry, should have given some more details beforehand, but think, I'll give the Gazelle a try (maybe that my best idea^^), because the KA-50 is not the most exciting thing to fly. ;)
