I used both the x52 and x52 pro. If you want to use the get a Belkin power USB hub. I got tire of having to replace them one a year so i got a ch stick. Been flying on the ch for a year and a half now with no issues.
Problems I had with the 52s:
1 after a couple months they would start to lose calibration at random times, usually in a fight.
2 the pitch, roll, and yaw would get real "twitchy" after about eight months.
3 I would start to lose hat switch veiws at about the one year point.
I still use the throttle from the last one I bought, the 52 pro. I had hoped the pro would hold up better but it did not.
On the other hand, I have Saitek pedals and have no complaints there. With the CH stick I have, pedals are a must, it does not have a twist option. The pedals I have now, i bought in 08 and they are still going strong
