I've got 12 hours on the Huey. It's very easy to fly in real life, very intuitive, as opposed to flying in DCS. I don't know if this is because of the lack of good controls, peripheral view and the seat of the pants feeling, or if it's because of the flight model.
Other than that, I think the flight model is very very good.
Sometimes though, I think the Huey is TOO susceptible to settling with power.
