I think the jets are still pretty ropey (I don’t fly them much) but the C152/C172 and other GA aircraft navigation and avionics seem to have improved a great deal. I hope Asobo will make use of some of the mods, as long as they aren’t GPL injections, they could just import the changes to the flight models after a short review for example.
I would think many of the developers of those mods would be happy with a credit in MSFS “C152 tuning by James Smith” somewhere, as they seem to be mostly free ?
