Mine's off center as well, both the X axis as well as the twist rudder are too far to the right. I did not manage to fix it in Widows' calibration tool, however I did come up with a workaround for it in the Saitek software:
- In the Saitek software, go to the Settings page for the stick.
- Choose the axis to edit.
- In the lower left corner of the window under Curve Profiles, choose "J".
- Add a bit to the Curvature value. For example, a good value for my X axis seems to be about 515.
- Click Apply, and it takes a few seconds to save.
- In the DCS control options, use the Axis Tune feature for that axis.
- If the small red square is in the center of the large black square when the stick is physically centered, then it's OK (move the stick a bit to get it to update after it's been changed it in the Saitek software). If it's not OK, then go back to the Saitek software and change the value a bit more, until it looks correct in DCS Axis Tune.
It's probably possible to fix it just in Axis Tune in DCS, but I did it in the Saitek software so that it's OK now in other games as well.
EDIT: I played around a bit more with the Saitek software, seems like another way to push the center is to change the Deadband or X-sat values depending on which side you want to push it towards (still using the "J" Curvature Profile").
I don't know which method would be better, neither is probably ideal but at least for me these workarounds are better than having an off-center stick waiting for Saitek to possibly update their software, so... :ermm:
