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.
