I tried it some time ago and it works in AH, but it's much fuss.

Not because of the way trackIR works, but because of the way AH mouselook is implemented. You have to reverse the axis in the software. You have to callibrate the mouse in AH setup.
Once everything is ok you can replace the mousebutton with a keyboard command then you have to press this button everytime you want to use trackIR. Bit of a fuss really, because to use trackIR effectively it's better to have it active all the time. I wish the Hitech developer could make it more like IL2.
Despite all of those things, once you get it working, it works really well actually.

But too much fuss to set it up properly. Mouselook's something could be implemented much better by Hightech Creations imo.
Once you get used to mouselook with trackIR there's no goin back to snapviews.
