Using the VG System
The Sport 2 VG system uses a reduction system of pulleys both inside the sail behind the crossbar
center, and also inside the right downtube. Tightening the VG increases the spanwise tension which
the airframe places on the sail, reducing the spanwise twist and the sail elasticity. The result is an
increase in L/D performance and a reduction in roll control authority and roll control response.
The VG is activated by pulling laterally on the VG rope and then moving the rope to set the rope in the
V-cut knife cleat. The recommended procedure for increasing VG tension is to grasp the rope firmly
at the cleat, and pull straight across the basetube.
VG full loose is for maximizing roll control authority and roll rate. Due to the slightly slower trim and
increased pitch pressures at VG full loose, you may find that total effective control is actually im-
proved in some conditions at slightly tighter settings up to VG 1/4. VG settings between VG loose and
VG 1/3 are recommended for working lift when any significant degree of turbulence is present, or
when you are in proximity to terrain or other gliders.
Between VG full loose and VG one half, the glider retains good lateral control authority and response.
Tighter than VG one half, the glider’s roll pressures increase significantly and the roll rate becomes
significantly slower. Tighter VG settings are recommended for straight line gliding, or for flying in
smoother conditions when well clear of both the terrain and of other gliders. The stall characteristics
of the Sport 2 at tighter VG settings are more abrupt and less forgiving and the glider is more suscep-
tible to spinning. Full breaking stalls and accelerated stalls at tighter VG settings are not recom-
mended.
