Thanks for the reply's.
Video didn't work, so scrap that, i see that you all get what i mean.
What do you mean exactly, i don't remember having this problem with flight sim X.
Edit, just checked with the calibration option in flight sim x, and its the same prob.
Its a joystick that cost $50, so replacing the hardware in it (assuming that's what you mean with potentiometers) is not really worth the cost.
