Oh, this might be a long answer!

Yes Works OK if I do this.
This is where it gets a bit complicated. In short Yes however, once I cleared that assignment I still didn't get any rudder movement in the sim.
Now, for the complication. I only assigned the Steering Tiller as that is how I have my FSUIPC4 in FSX/P3D3 however I have since noticed that not only has that control been renamed it no longer works the same.
When it was named Steering Set (way back then) it is behaved as I would expect it would in the real world (on large aeroplanes) and a quirk of FS allowed it to also work the same on light aeroplanes. However, since it became Steering Tiller it actually your documentation states that it interferes with the rudder which a real steering tiller never would as it only turns the nose wheel steering. The only reason I can make comparisons with the real world is I am an aircraft engineer. As it currently is I think it will cause problems when FSLabs A320 is released for P3D4.
Set the Rz axis for ailerons, worked fine.
Nothing wrong with my device. Works as I would expect it to in FSX (FSUIPC 4), FSW, X-Plane 11, DCS and P3D3 (FSUIPC 4). It is only in P3D4 trying to control the rudder via FSUIPC v5 that I have problems.
You have previously stated that my FSUIPC4 installation is no where near up to date (Jan 17!) so as a test I will update that to the latest and see if this problem shows itself in those sims that use it.
I'll let you know.
