This is the best aircraft mod, can it be updated for 1.1?

Yup.

Should be up any moment now.

Crashed when select helipad:

Error while running event HelicopterRevival::on_gui_click (ID 1)
LuaEntity API call when LuaEntity was invalid.
stack traceback:

Rats. Will fix asap.

Hello. There was such an error when loading if the Russian language is enabled in the game:
Error ModManager.cpp:1552: Не удалось загрузить мод "HelicopterRevival": Failed to load locale: Duplicate key "item-name" in property tree at ROOT.
There is no error in English, everything works fine. How to fix?

Uh... Some entities seemed to be cloned in the repository. I can't fix it right now, but I'll push another update tomorrow.

Oh yes, everything works) Thanks for your prompt support)
