I have uninstalled everything but Navigraph when flying the Arrow III. It has been crash free except for when the 530 mod has been in the Community folder.
I have also stopped using any other Garmin mods at this point in time; I seem to have eliminated CTD events by keeping the Community folder all but empty, except for Navigraph and the JF Arrow III. Also have the “Clean Grey” interior mod for the little Piper.
