Congrats on your Christmas prezzy!
I've heard some stories about how the X52 throttle kinda gives out after a short while, so don't throw away your Logitech stick. I'm using the Logitech Extreme 3D Pro with the X52 throttle. Works great. I was able to find 2 working spare throttles, but X52 sticks don't seem to be available for backup.
I had to calibrate my Logitech before it worked well with ED. Before calibration, it always tended to roll and yaw left.
<edit> I pulled the detents out of the X52 throttle. makes it a lot friendlier to use. </edit>
