If you have plane experience then quite a lot is basically the same in forward flight. Yes you do need the rudder/tail control more doing a turn...the Helis tail will hang down as you turn otherwise...I have found heli flying has improved my plane flying doing this 'co ordinated turn'.
The hardest bit was getting the hover just right...anyone can fool about and let the heli drift...but holding a nice stable hover is the first skill. The transition into forward flight and vice versa is a bit tricky at first.
I used two 'models' on EasyFly (my first sim) one was a jetranger that was quite docile compared to the '3D' stunt heli...that was a jerky twitchy little feller that one
Once I mastered the jetranger model I kept at the 3D one till I finally got on top of it...then I went out and bought my first heli and radio gear...never looked back.

I like the planes...have a stunt one here that I broke a short time ago...I will fix it but enjoy heli flying more really.
