There are two hang point positions; a lower one and higher one.
Ozone recommends using the lower hang point for free flight and
the upper one for powered flight (to help reduce the distance to
the brakes when using a high-hang point motor harness). Ensure
both risers are connected to your harness with the same hang
points.
Trimmers
The Viper is supplied with a trim riser set as standard. The trims
should be set at the normal position (i.e trims pulled down so that
all risers are the same length) for take off and landing. The normal
trim setting is ideal for climbing under power and whilst thermall-
ing. Brake pressure is lighter and the handling at its best on the
slower speed trim setting. During straight flight the trims can be
released for an increased cruise speed; perfect for maintaining
height and speed. Using the trims affects the amount of reflex in
the wing, by releasing the trims the reflex is increased creating a
faster, more stable aerofoil. However in strong turbulence we rec-
ommend returning the trims to the normal position (pulled down)
and flying the glider actively.
Accelerator System
To set up an accelerator on the ground, ask a friend to pull your
risers into their in-flight position while you sit in your harness. Now
adjust the length of the line so that the main bar sits just beneath
your seat. You should now be able to hook your heel in to the sec-
ondary (lower) loop of the accelerator.
The accelerator must be slack enough to ensure that the front ris-
ers are not pulled down in normal flight, but not so long that it is
impossible to use the full range of the speed system.
Once set up, test the full range of the speed system in calm fly-
ing conditions: ensure that both risers are pulled evenly during
operation. Fine-tuning can be completed when you are back on the
ground.
IMPORTANT: Using the accelerator decreases the angle of
attack and can make the gliders recovery from a collapse
more aggressive, therefore using the accelerator near the
ground or in turbulence should be avoided.
Harness and Motor
It will be in your harness that you will enjoy flying... Therefore, we
recommend you spend the time on the ground to adjust your har-
ness' different settings. Hang from a solid beam and double check
that you are comfortable and that you can reach the brake handles
and speed bar before flying.
The Viper is suitable for all types of motor. There are many differ-
ent motor units available and it is vitally important that you choose
one that is suitable for your needs, weight and skill level. Always
seek assistance and advice from your instructor or experienced
pilots before choosing equipment for yourself.
Total weight in flight
We strongly recommend that you respect these weight ranges
and fly the wing most suited to your weight. That way you can get
many hours of flight both powered and un-powered with the same
wing.
