Free Flight
I purchased the FSR500 on the FS2020 Marketplace, and was able to enable it in FS2024. Everything seems to be fine, except that it always defaults to the first livery in the list (UrbanGold) instead of the livery I’d chosen in the last flight (ArrowNavy.) “Save and Back” only saves the selected livery for the current session. I’m forced to re-configure the plane each time before a flight to use the livery I want.
I think that report also covers what you are reporting: Aircraft variant and livery setting is not saved between sessions. (it did in 2020)
The aircraft selection from last flight should be saved not only when you quite the sim and launch it again, but also between 2 flights, without leaving the sim.
Is a bug with all msfs 2020 airplanes inside msfs 2024.
Asobo is aware, i notified them during dev Alpha, will get fixed eventually.
Best,

Thank you, Raul.
Thanks. I added my info to that bug report.
It seems this issue still hasn’t been fixed…? The last variant and livery are saved in the selection for the 2024 aircraft, but not for any of the 2020 aircraft 
SU4? Most things are fixed on SU4..

I am not in SU4 Beta…
Then wait until you are on SU4 and retest
