I present here a tune up auf the Tu-124 K V-643 Indian Airforce. The existing simulations of the Tu-124 had a serious bug with its NI-50 navigation system and lacked VOR radios. After a work of nearly one year I present here my solution to these problems. Thanks to the original authors and how to install can be found in the file “Installation and thanksgiving” which comes with this download. Please REFER to the Docs I have uploaded today.
