Hey Leemz, I'm having the same problem with this game you had with the xbox version, huge deadzone in the flight stick input.
I tried the demo with my MSFF2 stick and it's much, much better than the AV8R was on the 360. But, the default button layout sucks. It doesn't make use of the 8-way hat on the stick! Huh?! Well, I suppose I could hook up my TrackIR 4 Pro.
Anyway, I really like the look of this game but I just can't bring myself to buy it again (for the PC). I know, ultimately, it'll just end up disappointing me like the 360 version did. But, I'll play around with the demo for awhile.
