I dont actually need FSUIPC, SPADnext or Axis and Ohs. (I downloadded them a few months ago to try them but way over-complex for what I need). My button box wortks fine as a simple joystick controller, just needed to map the rotary encoder to the correct binding in-game, which was OBS. Now when I depress the rotary encoder it cycles thru the obs modes, and when i rotate it, it increases or decreases the crs (when in VOR1 or VOR2 mode). Nice and simple and effective!
