I doubt you'll find anyone here who's actually flown a Huey
but it seems to be suitably modelled as far as I can tell. It's certainly completely different from the other helos and DCS generally has a good reputation for such things.
And of course DCS has a pretty good controller tuning feature so you can set whatever controller(s) you have to be more in line with how you think it should be.
Other than that, ED often has "free" fortnights where for two weeks you can try almost any of their modules for free. As we approach Christmas I daresay we'll see another pretty soon, I think they do them every 6 months or so.
