Yesterdays openbeta patch broke many custom control configs. Dont panic, a hotfix is being worked on.
For those of us not patient enough to wait for that the fix is in: In your DCS install directory/mods/aircraft/plane/input there are new default input files. Delete the ones that pertain to your hardware. So /mods/aircraft/A-10C/input/joystick/joystick HOTAS Warthog.diff.lua needs to go. and all its little brothers and sisters in the other aircrafts’ folders. I used a mass renaming utility to seek out *Warthog.diff.lua and move them to /dev/null.
It works.
In other news, the MiG-29 got a snazzy new flight model and it. Is. Glorious. Havent managed to land it in one piece so far.
