The other controls on mine worked OK for me, but elevator (could be a personal problem!

) is way to sensitive. I line up horizontally on targets fine, but unless I dial the elevator way back I alternate between too high then too low. Its due in part to the dead zone I think, as it causes a slight delay in my input on the stick to when the plane responds, then I overdo it as it doesn't happen quick enough.
Inside the stick there is another spring that provides the rotating resistance (it goes over the analog pot for the rudder). I took that out, held the gap open (makes sense when you see it) to where it would just lightly apply pressure when the stick was centered, then heated it with a torch to 'set' it to no tension there. Reinstall (after a dip in water to cool) and reassemble. My stick now takes may 1/4 the effort to rotate, makes the rudder input a lot smoother, and more importantly to me is a lot easier on my wrist.
Sounds trickier then it is, took less then a half hour to do.
