Setting up the APUS RS and test-flying
to each other), otherwise you may
experience symptoms of fatigue in long
flights. You should still be in a comfortable
flight position even when the speed system
is used to its full extent.
You will not be able to use the paraglider’s
full potential if the speed system is too long.
Fasten the speed bar to the harness before
launch to avoid tripping over it when
preparing to launch or taking off.

How the APUS RS speed system works
WARNING
Do not make the speed system too short.
The glider must under no circumstances
be pre-accelerated as a result of the
adjustment being too short.
Problems (such as collapses or tucks)
have a more drastic effect with increased
speed than in unaccelerated flight. It is
generally strongly recommended that you
do not use the speed system in turbulent
areas and when flying close to the
ground, because of the increased risk of
collapse.
Speed limiter
The APUS RS offers an above average
maximum speed.
The dynamics in fully accelerated collapses
are corresponding to the speed. Usually the
canopy reopens very fast and without
remarkable turning or loss of height. Only
the pitching during the reopening shows the
dynamics.
For the APUS RS 18 the speed limiter must
be mounted to meet the regulations for a
Class B paraglider in the weight range from
55 to 70 kg.
