it started developing a nasty habbit of de-calibrating itself at the most inappropriate of times. It would suddenly screw up on the elevator axis. It would have very little input for about half the travel and then it would input full lock. This was very disturbing. Just try dogfighting with no elevator input but none and full and that about sums it up. I calibrated in game, in windows, to no avail. This was not looking good.
Not to bust your chops or anything, but you do realise that this is a power source problem for the X52s?
Some computers do not put out enough power from the standard USB ports resulting in exactly what you describe: periodic loss of calibration resulting in almost zero output from the mid-range of the joystick action (ie; it's either at idle or full input).
This problem is solved by buying a $20 powered USB hub which runs of a wall-socket power source.
I run my X52, gaming keyboard and iPod charger off my USB hub and since then I have not once had a problem with calibration.
You broke your joystick for nothing and just wasted $230.
