It's hard!  I downloaded the demo (I just got a trackir, and I wanted to try a game that supported it), and the graphics are beautiful, but I can't stay alive for more then a minute.
If I fly the Mig-29 scenario, I try to follow the mirage and exceed maximum angle of attack.  If I try to boom & zoom, I get a missile up my tailpipe immediately.  In the A-10 scenario, the dang shilka eats my lunch unless I feed it a steady diet of flares & chaff.
I'll learn, I just need to practice.  I'm gonna get it for sure, pretty amazing looking. 
Now that I have the trackir, I sure wish AH had native TrackIR  support....
