This is a generic glider model designed for high-speed 
slope soaring and F3F racing, of the kind of Crossfire,
Skorpion and others.
One among a number of nice 3D models can be selected, 
all sharing the same dynamic behaviour.

Please select "load mixer default" to automatically
setup the preset snap-flap setting.
      
Aerodynamic and mass properties updated by Luca Gasparini.
