I think we need the equivalent of AA for the X52!
I had a bear of a time with it as well, but it gets better....actually, it gets great!
First, load the right stick map, so you can use both hat buttons. I can't remember off hand, but it's not hard to find it.
Dampen the movements near the center. It is a sensitive stick, and needs to be de-tuned near the center or every twitch will result in the nose swinging back and forth. Dampen all three axes.
Finally, just fly. You will develop the touch, and come to love the stick, I promise.
