Hey fellas!
I used to get that *alot* - I was mostly killed due to that.
Try this:
1. calibrate in windows.
2. calibrate in AH.
3. Set deadstick and damping way up to 25-30% for both
4. Have a look at what way your sensitivity sliders are set. I have mine set in a sloping curve, with big differences in the beginning, and lower at the high end. Try reversing this if it doesnt help. Rather, I'd try the reverse setting first; ie it starts with smal increments and ends in large ones.
5. Buy a new Joystick
I'm not pulling your leg here. Sudden spikes in movement can be caused by worn or bad parts in the joystick. You can see if this happens in the joystick setup.
6. take the joystick to your dealer and say you want a Thrustmaster Afterburner instead
(okey, this was not serious)
Hope it helps!
