Greetings fellow rotor-heads!
I've only scratched the surface with both the Huey and the MI-8, as I spend most of my time in the Ka-50. I've been flying lately, with all of the auto-pilot channels off, and it seems (naturally) to feel more like flying a previous generation helo like the MI-8 or Huey - which got me thinking....
If any of you haven't yet taken the Ka-50 up, or have just begun - a bit of advice:
Since you're used to and presumably comfortable with flying the older gen helos, I would suggest you start flying the Ka-50 with all of the auto-pilot channels off as well -- as it will feel more like the experience of flying the other helos -- then you could enable a single channel, one at a time, to see how it affects the flight controls.
If I had to do it all over again, I would have started this way myself, hindsight being 20/20!
