the canopy is marked by the UP logo at
the leading edge.
Inflate the glider with a steady run and
remember to position your arms so that
they are a continuation of the A risers. As
the glider comes above your head, you
should glance up to see that the entire
canopy is inflated and flying. The
UP Trango XC has a low surge tendency,
so there is usually no necessity to brake to
stop the glider from over-flying you.
Directional control should only be
attempted when the glider is above your
head. Excessive braking will cause the
wing to drop back.
Only after checking that the wing is
properly inflated do you apply slight brake
pressure and accelerate rapidly down the
hill. After a few steps you will reach flying
speed and become airborne.

The UP Trango XC has a wide useable
speed range, coupled with excellent
stability at all speeds. The speed can be
set with the brakes to optimise
performance in any situation.
Maximum glide speed is achieved with
the brakes released completely,
whereas minimum sink speed is with
approximately 10-15cm of brake applied.
Further braking will not improve the sink
rate, but the brake pressure increases
noticeably as the glider reaches minimum
speed.

Flying close to the stall
point is very dangerous and
should be avoided. At speeds
below minimum sink the
danger of entering an
unintentional stall or spin is
increased dramatically.

The UP Trango XC is supplied with a
speed system, which is activated by a
foot stirrup. Full application increases
the speed by approximately 18 to 20
km/h. In certain circumstances the use
of the speed system is extremely
effective, and it should be an integral
part of your flying.
The speed system should be used
when you are flying through sinking
air, when trying to achieve best glide in
a headwind, or trying to cover the
ground as quickly as possible. But it is
important to remember that the glider
will be more susceptible to collapses at
high speeds, so the speed system
should not be used in extreme
turbulence. If, with the speed system
applied, a collapse occurs then it
should be released immediately. Some
warning of an imminent collapse is
afforded by the tension felt in the
speed system; should the tension
suddenly reduce then the stirrup
should be released and the glider
returned to normal trim speed.

All extreme flight
situations, such as
collapses, happen more
dramatically at increased
speed. Therefore the speed
system should not be operated
near the ground or in
noticeable turbulence.

The UP Trango XC is an agile glider
and reacts immediately to pilot input.
Brake input and amount of weight shift
induced will define the radius and bank
angle on the UP Trango XC, and will
allow it to be controlled with ease.
