There is a text file in the Tigermoth download, called add.txt, which contains the lines that need to be added to the air.ini, the plane_ru.properties, and the weapons_ru.properties files.

air.ini is in ...\MODS\STD\com\maddox\il2\objects

plane_ru and weapons_ru are in ...\MODS\STD\i18n

Back up these files before editing, as a mistake can be fatal.
