Sure thing i see the logic there and yes i know there is mix of languages in real cockpits, but i just seems strange since it's a mod. All the old files will get overwrited when this mod is turned on, so how i see this is that it doesnt really mather what files it's overwriting since we see the final product which is in this case ur awesome mod. All that im trying to say is that everytime when i stop flying etc. A-10C i dont want to disconnect from server, go to options change language from english to russian, connect back to the server being able to fly with MiG-21 with finnish cockpit.
Edit: Plus while alot ppl is still learning this plane, all the tooltips would be also written in russian.
