Adjusting the brake handle (not valid
for APUS RS Hike)
The APUS RS is fitted with SWING
’s
Multigrip brake handles, which allows the
stiffness of the grip area to be adjusted. The
various options for stiffening the brake
handles allow them to be adjusted to suit
the pilot’s particular preferences. There are
4 levels of stiffness possible using various
combinations of the stiffening options. The
pilot is able to choose the appropriate
degree of stiffness by simply taking out or
inserting the various parts.

To remove the stiffeners, turn the Multigrip brake
handle inside out and push the two small rods out
through the opening
Multigrip brake handles after removing both
stiffening rods. These are the various parts:
Firm stiffening (bar)
Soft stiffening (tube)

Brake swivel

The procedure is the same to insert the stiffeners:
turn the Multigrip brake handle inside out and
push the two small rods into the handle again
through the opening.
There is also a swivel
where the brake
lines/brake handles connect to prevent the brake
lines from twisting.
Speed system
The APUS RS already has a high basic trim
speed,
but
this
can
be
increased
considerably by using the additional speed
system. It is particularly useful if there is a
strong headwind, for valley crossings or to
leave a dangerous area quickly.
The A - and B-risers can be shortened using
the speed bar. This decreases the canopy’s
original angle of attack and the speed of the
glider increases.
The speed system must be correctly fitted
and adjusted to ensure it operates smoothly
during flight. Before first launch, the length
should be adjusted to suit the pilot and the
line duct should be checked.
The speed bar and the riser are connected
by special Brummel hooks. Adjust the length
to the speed system so that your legs are
fully
stretched
