This video shows how simple it is to move settings between models in OpenTX.
I set up switches on a the Alien Main model that I like. Each switch adds Expo to each channel as I see fit. This allows me to change the stick feel in the field. Now I want to move the Expo switch configurations over to the Hubsan model since it like it (Got my Hubsan module from @goebish its great!).
This video shows how simple it is. I open both models individually and move the switch/channel settings between models.
