Very nice, thanks for sharing it. If recalibration doesn't work, here is another method that fixes the Z-Axis problem (I'll repost it here in case anybody is experiencing it):
1. Remove the chromed head screws from the side of the stick grip.
2. Gently separate the two halves. Be careful because there are four separate plastic parts that fit together.
3. Once you separate the halves of the stick you'll see the Z-Rotation pot on the top of the white shaft that extends from the main pot in the base.
4. Dab a very small bit of WD-40 (or something similar) on top and let it penetrate, then reassemble the stick.
This works like a charm for most people who encounter this problem. I noticed it happening once; when I saw this method I kind of doubted it but decided to give it a try, and it worked. Haven't got this problem since. o7
