Sorry to stir this up after a year. Does the english cockpit option now work out of the box? Leaning toward the Mirage for my next addition. But having had experience with both the CapSim Mig21 and the PT TU-154 in FS9, I prefer not having to translate the panels.
Side note; Language aside, that TU-154 is one of the better freeware products out there. Even if it were english, some of the protocols and systems were different enough from the MacAir and Boeing I am used to be be fun to learn.
