Hope it works! The jittering on mine is minor, and only noticeable when it is in the full down position and I hear the collective “rattling” against the stops. In flight it is not noticeable.
I am going to move forward with building mine out, adding mechanical stops to limit the lever travel to the axis range, and making a new bolt-on lever extension which will accept a future twist throttle to replace the provided lever. I already have the twist throttle but need to acquire another Thrustmaster T1600M joystick to cannibalize for the throttle project.
