-#### Known issue:
-1) If you have FPS lower than 20 it will not work correctly. Check your FPS. In FlightGear bridge look set View->View Options->Show frame rate
-2) Multiple models in hangar (with eletric engine) need up-to-date FlightGear from nightly budils.
-3) If you set-up mission take off to oposite direction than aircraft current heading, than the aircraft will fly directly forever.
-4) Internally starting scripts run ```fgfs``` with set of parameters to reduce graphic and connect FG to bridge. But before that, the starting script search for FG-Data folder by running ```fgfs --version```. If your output of this command does not contains FG_ROOT line, the script will not work. Check how is your FG run in system, by ```which fgfs```.
