Hello!
I have improved the Tupolev 134LK in many details.
https://github.com/HerbyW/Tu-134LK
New taxi and landing lights:
Ground-effect for landing and emergency breaking
Flightrecorder, engine smoke, navigation lights and electrical systems got some small adjustments to make it more realistic.
Roadmap:
Next will be the further improvement of the interior in the glass nose, and the implementation of an system to make the zero gravity flights possible.
How to contribute?
