heres a post I made earlier on this - since your the third person in a fortnight asking about it i might as well make a full help post on it (I might manage to whore some karma points for it
) but for now heres the original version.

You need the profiler
http://www.logitech.com/index.cfm/downl … areid=5439But you might want to use this first, just to make sure
http://www.logitech.com/index.cfm/downl … areid=5484The profiler needs to be open during the game. Im sure you can figure out the device settings etc, the deadzones are on the properties page of each axis.
To set up join an empty server with planes (I chose MEC on oman, theres no hangar to obscure anything) go to the airfield, set your throttle to exactly middle (so you dont fly off or back), jump in one of the planes, make sure your not moving then switch to F10 veiw mode.
We are interested in wing flaps (left/right axis, y) tail flaps (back/forward axis, x) and rudder flaps (twist)
First of all, check all 3 axis for flutter, meaning just rest you hand on the stick in center position and see if anything moves, then move it lightly and slightly but without actually activating an axis, there should be a tiny bit of play before anything moves, if any of the flaps/rudder flutters, note which axis needs adjusting and in profiler, slide the deadzone slider along a bit, then reload bf2 to test, repeat until theres no movement at all when you handle it in the slack area.
Next to find out the full range of the deadzone you need, get back in the plane like before and go through each 3 axes one by one pretty roughly, like you would flying. First whang it back and forward from top to bottom so the tailflap moves (x axis) and look for any movement at all in the wing flaps or rudder while you do that. The slightest flutter and thatll translate to instability in the air (a bit of rudder or flap while you are looping will throw you out at a different angle than when you went in) so go back to the profiler and keep increasing the deadzone value on the axis thats moving when it shouldnt (y or throttle) till nothing other than the tailflaps moves when you whang it back and forward.
Repeat with side to side, making the wingflaps move but the tailflap and rudder shouldnt- then the same with rudder making sure the tail nor wingflaps move. Adjust the appropriate deadzones until nothing else moves apart from the axis you are using.
Dont be afraid of big values, ive got 25% on my rudder (which sounds a lot, but its really not) and 16%/18% on my X/Y and its rock solid in the air now.
