Works fine out of the box. I was able to use my Flysky FS-i6X transmitter connected via USB to control the planes.

Works fine out of the box (FrSky Taranis)
only in Vulcan mode (what is anyway marked as beta in the game)
Worked fine out of the box even with a real transmitter (FrSKY Taranis, using USB dongle receiver, but I assume all transmitter would work which emulates a joystick device)
I've seen only one issue when I've changed the the graphics settings to use Vulkan rendering (instead of the default OpenGL), the game first exited without any message, I was able to start it again but with Vulkan rendering it was sluggish, steam reported 60 FPS, but I wonder if it was real. Anyway, changing back to OPenGL (game exited again on setting change) all was fine. BTW: the Vulkan rendering mentioned as "beta" in the settings.
All in all very good experience on Linux.

Decent little RC flight simulator. Worked well enough on my hardware.
The shadow draw distance was a little shallow with no apparent way to fix, but otherwise worked out of the box.
