Change how you fly!
Seriously. I just changed joysticks. I went from a CH to an X55. It has been a RE-learning process worst than TrackIR. I have used a CH stick forever and never had to change any settings, or scalings. I was very use to how the stick moved and reacted in the game and NEVER got a "dont move your stick...." error.
With my X55 I have been messing with the setting, scalings, spring tension and so on for weeks and I have run into the "dont move your stick...." error a number of times.... as well as other planes, trees, and vehicles.
The point is, DON'T MOVE YOUR STICK SO MUCH!
In your case your slamming the stick and rudders to push the plane that little bit more at stall speed to get the lead for a shot. Get your self into a better position next time, don't force the shot.
The reason it is set up like it is, is to penalize those that stick stir thinking to get out of being hit by you. This locks up their controls so you have a good opportunity at hitting a strait and level target for a second of two.
The other reason your doing this more often is what Morphied calls the "old man syndrome". Us old guys don't get many chances at kills in this game any more, so when we do, we kinda OVER do it.
Especially in todays game where your more often than not trying to beat 5 other guys to the kill, or kill this guy quick because 5 others guys are coming after you.
