I refer to this post a few years ago.
I got this working a long time ago in P3D v3. I tried to get it working now in v4 with the A330. I want to assign one axis to the elevator and when on ground to the tiller. I used the multiaxis funtion to change the axis on a button press. Unfortunately it is not working. I used the "Controls List for P3D4 Build 32097.txt" file in the documents folder to find the elevator and tiller axis (throttle 3 axis for the aerosoft airbus) but the axis are not working.
If anybody could help me with that I would be very thankful ;-)
