Hi Apoapsisgame,
I had a similar experience to you and this thread below solved the problem, I know folk don’t like messing around inside the sidestick but the fix is quick, and very easy to do, and only takes 20 minutes to complete.
The cables that feed the yaw potentiometer in the sidestick require re-routing or easing, at the moment every time to just touch the stick you are giving inputs to the Z axis potentiometer.
1, unplug then unscrew and remove the top two buttons ( Red & Black)
2, Lay the sidestick on its right side on a cushion or anything to support the bottom half of the stick.
3, Remove the remaining 3 screws, 1 in the centre of the stick 2 at the base.
4, Ease off the top half of the stick to expose the wires ( you can put tape around the base of the stick to hold everything in place while you are adjusting the wires.
5, I didn’t find any trapped wires but they were bunched close together and some were taut, so one by one I moved about 7 wires to the other side of the insulation lump of glue. This freed all the wires and it looked a lot better and it’s working great now… took less than 20 mins.
