My biggest problem with the deadzone is that at least with my Aviator, turning down the aileron or elevator sensitivity in the game's options actually decreases the maximum deflection of those control surfaces.
With the sensitivities turned down to 3 quarters I can get used to the feel of the gunnery even with the deadzone, but then I'm also decreasing my maximum turn rate by a good margin.
I managed to play one game on Live over Dover on simulator and it was beautiful.. tons of fun. But I can't stand the compromise between controlling my aiming point and the aircraft's turning performance.
If they can get rid of the deadzone and add a basic joystick calibration option everyone should be happy.
