I use the Logitech Radio panel and X-touch Mini, both excellent and add a LOT of usefulness. BUT, you need a bridging app such as Spad.Next (also excellent), or FSUIPC or Axis and Ohs…
I personally find Spad fantastic and there are numerous videos to help with anything. I fly the PMDG 737 predominantly and now have almost no mouse interaction. ps also just got a mini Ipad with AviaWorx software (10Euros) so I can run the CDU on the Ipad…caps it all off for me…
