Thank you.
Have read the instructions in both manuals again and again and have tried to follow your comments/instructions in your most recent post, but all in vain.
I was aware that for MSFS2020 FSUIPC is not really necessary but still have purchased FSUIPC7 to have prop feather and sort of Beta range in the King Air. Fly nothing but the King Airs.
I am not new to FS, in fact I have owned the paid FSUIPC since the beginning and never ever had experienced such a struggle. For you and lots of others the manuals are clear enough, but not to me, sorry. I am not in computers and programming, I am only a user, but I do have a university degree in another sphere.
Are you 100% sure that one can use Lvars to assign left and right landing lights to separate buttons? Did you try that yourself?
Best,
Roland
