First thing I would, is watch this video.
It explains very well, the differences between Spektrum set up, and 9XR, even though, they are talking about a Taranis.
If you can, I would upgrade to the firmware from Open TX.
Its so much easier to work with, than the standard version.
It has a model set up menu, that walks you through setting up, specifically for, Plane, Heli, Multirotor, or Wings.
You will need the CompanionTX software.
