Sorry for not answering before now. Have been sick for a few days.
I deleted my FSUIPC folders and reinstalled it. After that process, I got my thrust levers properly working.
No, I have not send a ticket to LM. I can see that many others also have problems with the controllers (joysticks etc.) in P3D.
I do not know what the problem is all about. In my controls sections on P3D I can only choose the mouse yoke. My Saitek and Hotas Warthog is not even listed within P3D controls page.
Another question is how I can assign my levers to the reverse thrust and the same time use them as normal thrust levers? There is not a reverse range options on my Hotas Warthog. So I think that I have to assign a bottom to tell the software that now the levers is in reverse mode, or how??
My best regards,
