Elevator in was thunder?

I was last Thunder downloaded on my Xbox one and have so far only played with the tank now I wanted to try but also the plane and have started the tutorial. Since I noticed that probably the elevator is not assigned to a button and thus can't change the height of my plane. How can I adjust that? Thank you in advance

Esc (or whatever key is on the Xbox)

control

Primary control axes

Select "Nick Axis" and click on "Edit Axis" at the bottom right

(Would have to work on the Xbox, but play WT only on the PC)
