I carried out the 'slide by' magnets mod on my X52 (as shown earlier in this thread), I have to say it has made a huge difference to the sensitivity and no dead zone - what a transformation!

Centering the hall effect IC is critical for optimum results though and this is extremely time consuming to do by just trying to locate the magnets precisely. I also noted that if the magnets were mounted incorrectly regards their 'polarity' the Axis direction becomes reversed and this needs to be checked before permanently fixing them.

If anyone is contemplating doing this I snipped off the small plastic nipples and the lips of the plastic flange on the rear which locate the small Hall effect PCB in a fixed position. I then enlarged the securing screw hole by a mm or so (there is no track to damage and this can be done by hand using a twist drill or a needle file). Firing up the windows properties panel, I was then be able to easily adjust the Hall sensor PCB over the relocated magnets for the optimum position that gave the best sensitivity to light deflection of the yoke in both Y and X axis. The Hall Effect PCB securing screw was then fully tightened to hold it in the optimum position.

I also changed the spring but that is another story..............
