Ok I think I need to use the Defining A Flight Model - SDK Documentation
It looks like a lot of stuff to enter. Not a quick job and I have never had much luck with the scenery SDK and there were several videos on doing that. I will look into it further . The club field I fly at is in photogrammetry. I thought if I used a rolling cache it would use those graphics since I will be running MSFS off line (no internet at the field). But it does not and the graphics are pretty bad when flying off line… I am using a rc transmitter for the flight controls. That works very nice…
