Crazybroadsword;
looking at the AH in the picture posted I would say that was more like 45 degrees not 80 as the first 3 bars are at ten are degree markings then the next one which is where it looks to be just over is 45 .
Now I'm no R44 pilot like yourself, and therefore cannot talk with any authority on type, but I don't think you are looking at the AH. Could it be that you are referring to the turn and slip indicator?.....
...which is pretty scary should you ever have to rely on your instruments
