Reported over on the FSDeveloper forums by contributor “rotorhub” is the news of a Freeware release Falcon 20E Biz Jet. Download available from Avsim libraries. Nice looking model for freeware, don’t be expecting Carenado quality, but a very nice representation of the aircraft.
The aircraft has a default exec jet cockpit (2D), but also a nice looking custom VC. Sound files too are default, though the developer in the read-me file has given suggestions for downloads of sound files etc. So be aware reading the read-me file will give options to further enhance the model.
Title of download at AVSIM : Dassault Falcon 20E P3D V4 and FSX version 1.1
Here are our in-sim (FSX) screens of the aircraft.
