Hey there - glad you were able to find an in-game solution with your hardware. From what I've been able to gather there is some limited joycon support, which you seem to be successfully making use of: single usb device, with a limited number of inputs.
That limited support is appreciated, but, for individuals who want to be able to use a separate flight stick and throttle (and even potentially rudder pedals) that each have their own USB cables - this is still a bit of an issue. I'm going to give it another shot when I have a chance, but, I also was having a problem where inputs on my flight stick were being recognized in some capacity, but they weren't binding to controls properly in the Joystick settings. Meaning: pushing buttons causes things to happen in the UI, but nothing actually registers in that joystick control bind menu. I think I had read in another thread that if a device has more than some set number of axis inputs, the game reads it as a gamepad and not a joystick, which locks it out of keybinding. I could be wrong about that, but in any case - I personally still have not been able to get this to work properly with the settings currently available in-game.
Even if I am able to get just the flight stick itself working with what's available in the menus (which would be a start) - the button layout on mine doesn't really lend itself to full-vehicle control. I'm not sure how I could account for jet throttle / helicopter collective in an intuitive way.
