Hi guys, just thought I'd share this.
If you've ever read anything negative about the Saitek X-65F, it'll be probably be about a few users who gotten drift in their sticks axes and "had to return them". :(
Yesterday I started to get this problem with mine drifting hard left and forward (almost full deflection). I Googled the issue to find people lamenting the lack of calibration tools in the configuration software etc.
It seemed odd to me that such a sophisticated peripheral could become unusable (especially so quickly), so in a brief moment of inspiration I disconnected the joystick from the throttle hub while keeping the throttle attached to a usb port. (If you do this the device does not appear to be disconnected to the OS, so you can safely do this in-game).
I reconnected the joystick again and allowed it time to rebind to the throttle hub. The drift was gone: according to the config tool all axes were dead center.
Experimentally I put the joystick on a radiator for a short while, and sure enough some drift came back. I rebound the joystick and recalibration occurred. Since then I've kept the room temperature as constant as I can, and have taken care not to touch the joystick while it is binding. No drift has occurred since.

So what I can glean from this is that:
(a) axis calibration occurs upon binding/rebinding the joystick to the throttle hub.
(b) the force sensors are sensitive to temperature changes.
