To run, try:

fgfs --aircraft=beech99-v1-uiuc

Files and directory structure required in $FG_ROOT/Aircraft/ to fly the
model:

beech99-v1-uiuc-set.xml
beech99/Sounds/uiuc/beech99-sound.xml
UIUC/beech99-v1/aircraft.dat

These files above come with the FlightGear base package.

Files and directory structure required in $FG_ROOT/Aircraft/ to see the
external 3D model:

beech99/Models/uiuc/beech99/beech99.ac
beech99/Models/uiuc/beech99/beech99.air
beech99/Models/uiuc/beech99/beech99.loc

These files can be obtained from Wolfram Kuss' website here:

http://home.t-online.de/home/Wolfram.Kuss/

The 3D model is here:

Download the zip file and model files in the directory indicated
above.  Under linux, the files from zip archive might need to be
renamed to lower case (if they are not already that way).  Renaming to
lower case will be necessary if FlightGear crashes when trying to read
the texture files.

To use the new aircraft model and not the default Opus glider, edit the
beech99-v1-uiuc-set.xml file and change the string:

"Aircraft/UIUC/Models/opus/opus-model.xml"

to 

"Aircraft/beech99/Models/uiuc/beech99/beech99-model.xml"

after the model files have been installed.

Model description and updates:

5/25/02 - First release: v1

* "Linear model" meaning that constants are use for stability
  derivatives.  The chief drawback of this type of model is that stall
  is not properly modeled, and as a consequence an unrealistically
  high lift coefficient is produced when the aircraft is at a high
  angle of attack.  As a result the aircraft can fly much more slowly
  than in real life.

* Model largely built from: "Small twin turboprop commuter airplan"
  data from: Roskam, J., Airplane Flight Dynamics and Automatic Flight
  Controls, Part I, DARcorporation, Lawrence, KS, 1995, pg 508-510.
