If considering the Thrustmaster 16000 FCS, take the time and google Z-axis jitter concerning the 16000 before you plunk down the bucks. It seems to be a crap shoot as to whether you get a good one.
In the last hour, I just opened a 2nd ticket on Thrustmaster support for the issue. Got a new stick earlier in the year and it had the issue right out of the box. Support said it was a defective pot. Been complaints concerning that for at least a couple of years. The replacement that they sent me was solid and worked good from mid May until this week and now it's gone stupid with the same issue. This second stick has very low time on it and gentle use.
The first time around on the warranty went smooth, although it took a couple of weeks to complete. We shall see how cooperative they are this time. Still have a few months of warranty left. After that I'll be looking for advice for something else.
