Ok, I figured it out and have it working the way I want…after trying some things. Apparently, in my case or it’s just something I didn’t realize is, when doing a combo/modifier and a POV button is…You select the POV direction first, then the modifier, not the other way around…Modifier then the POV direction.
Now, the POV alone controls elevator / aileron trim. If I hold down the trigger, then use the POV I can free look left/right/up/down…Perfect!
Thanks to everyone for the clue about the modifier!
