Lorby has pulled this app - because he’s seen how he can make a quick buck - gotta love Capitalism /s - and so there is no free way to get these to work. I’ve been bugging this in the Alpha and Beta and no one from the dev team responded, and all I got was ‘go get Lorby’s AxisAndOhs’ = which since this release he’s now pulled.
There IS however a free utility called ‘DCSFlightPanels’ which you can find on GitHub - Whilst it’s mainly for DCS, it does allow you to map most of the buttons, knobs, switches and levers to be keystrokes.
So no, the radio panel won’t work properly, but the switch panel and autopilot panel will mostly work. YMMV
