Swing Flugsportgeräte and the
environment
Protection of the environment, safety and
quality are the three core values of Swing
Flugsportgerte GmbH and they have
implications for everything we do. We also
believe that our customers share our
environmental awareness.
Respect for nature and the
environment
You can easily play a part in protecting the
environment by practising the sport of
paragliding in such a way that there is no
damage to nature and the areas in which we
fly.
Keep to marked trails, take your rubbish
away with you, refrain from making
unnecessary noise and respect the sensitive
biological equilibrium of nature.
Consideration for nature is required even at
the launch site!
If you are a smoker, please do not leave
cigarette butts behind.
Paragliding is, of course, an outdoor sport –
protect and preserve our planet’s resources.
Environmentally-friendly recycling
Swing gives consideration to the entire life
cycle of its gliders, the final stage of which is
recycling in an environmentally-friendly
manner. The synthetic materials used in our
gliders must be disposed of properly. If you
are not able to arrange appropriate disposal,
Swing will be happy to recycle the glider for
you. Send the glider with a short note to this
effect to the address given in the Appendix.

Section 2
Safety
02 Safety
WARNING
The safety advice given below must be
followed in all circumstances. Failure to do
so renders invalid the certification and/or
results in loss of insurance cover, and
could lead to serious injuries or even
death.
Safety advice
All forms of aerial sport involve certain risks.
When compared with other types of aerial
sport, paragliding has the lowest number of
fatal accidents measured according to the
number of licensed pilots.
However, few other sports demand such a
high level of individual responsibility as
paragliding. Prudence and risk-awareness
are basic requirements for the safe practice
of the sport, for the very reason that it is so
easy to learn and practically anyone can do
so. Carelessness and overestimating one’s
own abilities can quickly lead to critical
situations. A sound assessment of the
conditions for flying is particularly important.
Paragliders are not designed to be flown in
turbulent weather. Most serious paraglider
accidents are caused by pilots misjudging
the weather conditions for flying.
Paragliders themselves are extremely safe.
In the type certification tests, all component
parts of a paraglider must withstand eight
times the load of normal flight. There is a
three-fold safety margin compared to the
maximum extreme load occurring in flight.
This is higher than the two-fold margin usual
in aviation. Accidents caused by material
failure are therefore practically unheard of in
paragliding.
In Germany, paragliders are subject to the
guidelines for air sports equipment and must
not under any circumstances be flown
without a valid certification. Independent
experimentation is strictly prohibited. This
Manual does not replace the need to attend
training at a paragliding school.
A specialist must test-fly and inspect the
paraglider before your first flight. The test-
flight must be recorded on the paraglider
information label.
Carry out your first flight with the paraglider
on a training slope. For this flight and for all
other flights, you must wear an approved
helmet, gloves, firm shoes with ankle-
support and suitable clothing. Only fly if the
wind direction, wind speed and current and
forecasted weather conditions guarantee a
safe flight.
Be aware of the special responsibility you
have as the pilot in a tandem flight and bear
in mind the particular features of tandem
flying when you are making decisions before
and during the flight.
Familiarise yourself with any applicable
regional and national laws and regulations
before you fly.
This Manual must be passed on to any new
owner of the glider. It forms part of the
certification and belongs with the glider.
The TWIN RS was developed and tested
solely for use as a paraglider for foot-launch
and for winch-towing. Any use other than as
intended is not permitted. Do not under any
circumstances use the paraglider as a
parachute. Acrobatics are not permitted.
Observe the other specific safety advice in
the various sections of this Manual.
Safety notices
Safety notices are issued when defects arise
during use of a paraglider which could
possibly also affect other gliders of the same
model.
The notices contain instructions on how to
inspect the gliders concerned for possible
faults and the steps required to rectify any
faults.

Safety
Section 2
11
Swing publishes on its website any technical
safety notices and airworthiness instructions
which are issued in respect of Swing
products. We will also send you safety
notices directly by email if you have
registered your product (refer to “Product
Registration” in the section “Swing on the
World Wide Web”).
WARNING
The paraglider owner is responsible for
carrying out the action required by the
safety notice.
Safety notices are released by the
certification agencies and are also published
on the relevant websites. Services such as
RSS are also available which allow
internet users to follow various
websites and any changes made
to them without having to access
them individually. This allows
much more information to be
followed than was previously the case. You
should therefore visit the safety pages of the
certification agencies on a regular basis and
keep up-to-date with new safety notices
which cover any products connected with
paragliding (refer to Appendix for addresses).
Disclaimer and exclusion of
liability, Operating limits
Use of the paraglider is at the pilot’s own
risk!
The manufacturer cannot be held liable for
any personal injury or material damage
which arises in connection with Swing
gliders. The certification and warranty shall
be rendered invalid if there are changes of
any kind (incl. glider design, brake line
changes beyond the permissible tolerance),
or incorrect repairs to this glider, or if any
inspections are missed (annual and two-
yearly check).
Pilots are responsible for their own safety
and must ensure that the airworthiness of the
equipment is checked prior to every flight.
The pilot should launch only if the paragliding
equipment is airworthy. In addition, when
flying outside of Germany, pilots must
observe the relevant regulations in each
country.
The paraglider may only be used if the pilot
has a valid licence for the area or is flying
under the supervision of an approved flying
instructor. There is no liability on the part of
third parties, in particular the manufacturer
and the dealer.
Disclaimer and exclusion of liability
In terms of the warranty and guarantee
conditions, the paraglider may not be used if
any of the following situations exists:
the inspection period has expired, or the
inspection has been carried out by
unauthorised agencies or people
the pilot has insufficient experience or
training
the pilot has incorrect or inadequate
equipment (paraglider, protection and
helmet)
the glider is used for winch launching
using a winch which has not been
certified or by non-licensed pilots and/or
winch operators
Operating limits
The paraglider may only be used within the
operating limits. These have been exceeded
if any of the following situations exists:
the take-off weight is not within the
permissible weight range
the glider is flown in rain or drizzle, cloud,
fog and/or snow
the canopy is wet
there are turbulent weather conditions
and/or wind speeds on launch higher
than 2//3 of the maximum flyable

there have been modifications to the
canopy, lines or risers which have not
been approved
Note also, as part of the operating limits,
that:
the TWIN RS is designed for solo or
tandem paragliding
use by more than two people is
prohibited
WARNING
It is imperative that the instructions
contained in this Manual are followed at all
times.
Failure to do so renders invalid the glider’s
certification and/or results in loss of
insurance cover. Furthermore, it could
lead to serious injuries or even death.
This applies in particular, but not only, to
the instructions given in the sections
Safety, Flying the TWIN RS, Types of Use
and Dangerous Situations and Extreme
Flying.

Safety
Section 2

Glider categories and
guidelines
The Deutsche Hängegleiterverband (DHV)
has worked together with its safety
department and other German testing bodies
to develop directives for certification which
are based on many years of analysing
paraglider accidents and on the experience
of flying schools, flying instructors and safety
officers. These directives should help pilots
to select the glider which is appropriate for
their particular level of flying ability.
The information below about flight
characteristics and pilot skills required relate
to the classifications used in EN/LTF-
certification and are taken in part from the
LTF. There is also further information on the
website of the relevant licensing body.
WARNING
The descriptions of flight characteristics
contained in this Manual are all based on
test flights, which were carried out under
standardised conditions.
The classification gives merely a
description of the glider’s reactions to
these standardised tests, generally
without any intervention by the pilot.
The complexity of the paraglider system
means that the standardised tests can
give only a partial description of the
glider’s flight behaviour and reactions to
disturbances. Even a small alteration in
individual parameters can result in flight
behaviour which is markedly modified and
different from the description given.
EN/LTF certification
In the testing body’s final classification, the
TWIN RS was given a class B rating.
Description of flight characteristics
Paragliders with good passive safety and
forgiving flying characteristics. Gliders with
some resistance to departures from normal
flight.
Target group and recommended
flying experience
The TWIN RS is particularly suitable for
tandem pilots who are looking for absolute
flying enjoyment with the highest level of
safety and performance for themselves and
their passengers.
It is also ideally suited for professional use
thanks to its straightforward flight
characteristics and well thought-out design
details.
The TWIN RS is also certified for use as a
solo glider when the vario-riser is used.
This means it is also suitable for heavier
pilots who are looking for direct handling
combined with very good glide performance
and outstanding features in thermal flight.
Description of pilot skills required
For pilots who fly “actively” and regularly and
who are able to stabilise the glider overhead
even in turbulent conditions.
Suitability for training
The TWIN RS is suitable for use as a training
glider.

Section 3
Technical description
03 Technical description
General layout illustration
TWIN RS –BI different
The TWIN RS sees SWING take a
completely new approach in the technical
design of paragliders made for tandem flight.
For the first time the RAST system is being
used for a tandem glider. This has made it
possible for our R&D team to utilise the
advantages of a larger surface area, and
there are marked improvements when it
comes to launch behaviour, speed, stability
and handling.
The RAST technology means that the
glider’s launch behaviour is very harmonious
and forgiving, so there is no stress even if
the conditions are unfavourable and/or the
passenger is hesitant in the launch run-up.
The take-off speed stays low even with
maximum load, which makes the launch run-
up easier. What is most noticeable is that
RAST makes launch behaviour simpler when
there is a tailwind or no wind.
Once in the air, you will be impressed by the
TWIN RS’s sensational climb rate even when
conditions are light. If there is ever any
turbulence, RAST ensures extremely high
canopy stability and additional safety.
It is no exaggeration to describe the flare
characteristics of the TWIN RS as
outstanding and they make a gentle landing
a piece of cake.
Line system
The TWIN RS has A, B and C- line levels,
which fork twice from the bottom (riser) to the
top (canopy) and which are divided into
main, intermediate and top lines. The
individual line levels are connected with one
another using the “handshake knot” (loop to
loop knot).
The Maintenance and Service book has a
detailed line connection plan, showing the
individual levels, connections and line
descriptions.
With the brake lines, the individual levels are
bundled at the end with the main brake line.
This runs through the brake pulley on the
riser and is knotted at the brake swivel of the
control handle. There is a mark on the main
brake line which allows the control handle to
be correctly positioned.
The main lines are all attached to the risers’
Maillon quick links. They are fed through
special elastic rings and attached to prevent
the lines from slipping and to ensure that
they stay in the correct position.

WARNING
The paraglider is delivered ex factory with
the Maillon quick links secured using
Loctite(a strong thread-locking
compound) to prevent unintentional
opening. After service work, any quick
links which have been opened must be
secured again against unintentional
opening.
Risers
The 25mm wide risers specially developed
for the TWIN RS allow the pilot to use a
trimmer to adjust the speed of the TWIN RS
to suit individual preferences.
The riser also has a “big ears” support
feature.
There is more information on use of these
features in the section “Flying the TWIN RS”.

Setting up the TWIN RS and test-flying
04 Setting up the TWIN
RS and test-flying
Before the first flight
WARNING
A specialist must test-fly and inspect the
glider before your first flight. The test-flight
must be recorded on the paraglider
information label.
The TWIN RS goes through several quality
control checks during production before
finally undergoing a detailed type
certification test. Conformity with the
certified reference model is checked and
certified before the glider is delivered to the
customer. Extreme care is taken in the
manufacture of all patterns, lines and riser
lengths. They show a high level of precision
and should not be altered under any
circumstances.
WARNING
Any changes which have not been
approved or improper repairs to this
paraglider render invalid the certification
and warranty.
Adjusting the main brake lines
The TWIN RS is delivered ex factory with a
brake adjustment which is marked on the
brake lines and conforms to the certified test
sample.
This adjustment allows the pilot to steer and
land the glider almost without delay.
The main brake lines are checked by the
specialist before the test flight, and must be
fastened so that the mark is visible about
5mm above the knot.
The brake line length must not be
shortened.
Factory setting
Correctly installed brake lines have about
10cm of feed. This is how far you must pull
down the brakes before the trailing edge of
the paraglider starts to move downwards
and begins to brake. Note that the brake
cascades already cause drag by their
aerodynamic resistance.
The TWIN RS comes factory-set for optimal
handling so it is therefore not normally
necessary to alter the brake length.
However, you are able to lengthen the brake
setting if necessary to suit your personal
requirements.
If the brake adjustment is altered, under no
circumstances should it exceed or fall below
the tolerance levels given in the
Maintenance and Service Book for the
TWIN RS.
Incorrect adjustment
If the brake lines are too long, the paraglider
reacts slowly and is difficult to land. The
brake lines can be adjusted during flight by
wrapping them around your hands which will
improve the flight characteristics. Adjust the
brake lines to the correct length after you
have landed. Changes to the braking
distance should always be made in small
increments of no more than 2 to 3cm and
must be tested on a training slope. The left
and right brakes must be adjusted
symmetrically.
If the brakes are shortened, care must be
taken that the paraglider is not slowed down
in trim and accelerated flight because of the
brake lines then being too short. Safety
issues may arise and performance and
launch behaviour may deteriorate if the
brake lines are shortened too much.

Setting up the TWIN RS and test-flying
Section 4
17
WARNING
The following risks could arise if the brake
lines are too short:
there could be an early stall
the paraglider does not launch well
and there is a risk of deep stall
the paraglider exhibits dangerous
behaviour in extreme flying
the trailing edge of the paraglider is
braked in accelerated flight which, in
an extreme case, could cause a
frontal collapse

TIP
Environmental conditions can also cause
the brake lines to shorten.
Brake line length should therefore be
checked regularly, particularly if there is
any change in launch or flight
characteristics.
Brake knots
The overhand knot and bowline knot shown
below are the most suitable for connecting
the brake line to the brake handle.
Fig. 2: Overhand knot
Fig. 3: Bowline knot
WARNING
Loose, unsuitable or incorrectly tied brake
line knots can cause the main brake line
to loosen and then lead to loss of control
of the glider.
Ensure that only double overhand or
bowline knots are used and that they are
tied correctly.
Adjusting the brake handles
The TWIN 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 altered to suit the pilot’s
particular preferences. There are 4 levels of
stiffness possible using various
combinations of the stiffening options. The

18
Section 4
Setting up the TWIN RS and test-flying
pilot is able to choose the appropriate
degree of stiffness by simply taking out or
inserting the various parts.
Fig. 4: Removing the stiffening from the Swing

There is also a swivel where the brake
lines/brake handles connect to prevent the
brake lines from twisting.

Speed system (trimmer)
The TWIN 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, provided
conditions allow it to be used safely.
The B, C- and D-risers can be altered in
length using the trimmer. This decreases the
canopy’s original angle of attack and the
glider’s speed increases.
WARNING
Problems (such as collapses or tucks)
have a more drastic effect with increased
speed than in unaccelerated flight. It is
generally 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.

Section 4
Setting up the TWIN RS and test-flying
Tandem spreader bar
SWING offers suitable spreader bar TWIN
RS. They are offering various hangpoint
options to allow for height and/or weight
differences between the pilot and passenger.
These are shown in Fig. 8.
Differences in height are offset by attaching
the passenger's carabiners in the upper,
middle or lower loops (B1, B2 or B3) on the
front of the spreader bar.
We recommend that you use a steel
carabiner with adequate breaking strength as
the carabiner for the main hangpoint. Please
familiarise yourself with your country’s
national regulations.
