my install is C:\Program Files\Ubisoft\IL-2 Sturmovik 1946\MODS\XP-86 Sabre v1\3do ...etc

i added the lines to the bottom of air.ini located here:C:\Program Files\Ubisoft\IL-2 Sturmovik 1946\Files\com\maddox\il2\objects

Is it the only air.ini inside the IL2 folder? What kind of error is it giving you?
