Bug with saitek x52 controls
 

The controllers calibration drifts out of center after playing COD for some time. The controller does not have this problem in any other flight sim or game, only in COD.

A reboot of the system will return the proper calibration of the device.

Yup, one of the many little bugs in this otherwise magnificent sim. I reassigned the controls in the game menu. And I fiddled a little bit with the sliders. It works now, I don't dare to touch it again :)
