USER MANUAL

2. ABOUT THE WING
For whom the Coden?
Coden is a 2-row competition wing of 6,95 aspect ratio and 77 cells. It is dedicated
for highly skilled and experienced pilots. Even as the paraglider passed EN-D flight
tests, it demands that steering inputs are very precise and measured. For that
reason the Coden is meant mostly for active competitors.
THE PROJECT
Application of 2-row rigging brings about exceptional aerodynamics and makes
possible active steering even at maximum speed.
The aerofoil used in the Coden some reflex traits. The paraglider is resistant to
collapses, launches easily and has perfect handling. Especially worth
mentioning is its great longitudinal and lateral stability.
As in other our paragliders, risers of the Coden constitute a complete, very
comfortable and carefully thought out control panel, where each instrument is
placed exactly where it should be and works as it should. Modern risers of 12
mm width feature ball-bearing SmartPulleys, made on special order and
conforming to our own design. Comfortable SCT handles with Easy-Keeper
neodymium magnets will prove their worth during long flights.
Coden was extensively tested during many hours of internal tests, performed
in wide range of terrrain and weather conditions. As a result you got a
paraglider that will easily float in slightest lift, and covering long distances in
turbulence typical for a thermally active day won’t bring any problems. Speed-
system operation is safe and comfortable even in rough air. Coden has lots of
speed, great deal of lift, and generally it simply wants to fly – so don’t be
selfish and take it with you for a long XC ;)
We are sure that Coden is one of the best canopies in its class.
DESIGN
Canopy was designed in our CSG (Canopy Shape
Guard) system, comprising a number of elements
resulting in exceptional coherence and stability of the
shape. Below you will find a short description of CSG
subsystems.
Coden has an elliptic shape with slightly back-swept wingtips. The canopy is
made of doubled cells, with ribs supported by VSS (V-Shaped Supports)
system. Such design guarantees that the canopy stays rigid, the upper surface
is smooth with correctly reproduced aerofoil, and what is most important we
have fewer suspension points (thus reducing overall lines' length and drag).

Inside the canopy there is RSS (Reinforcing Strap System) applied on the
lower surface. RSS is a ballooning-independent reinforcement system made
entirely of paragliding fabric, stiffening and stabilizing the canopy.
The aerofoil was perfected with DOA technology (Dudek
Optimized Airfoil). It merges all our experiences stemming
from previous designs and as a special feature is optimized
with dedicated CFD engineering software.
The suspension points areas are additionally reinforced with laminated fabric
so that loads are equally distributed on three planes: vertically (with the ribs),
diagonally (with VSS system) and level through RSS.
All crossports have been prepared with application of OCD (Optimised
Crossports Design). Carefully designed shapes of the openings and their
optimal placement between stress lines guarantee efficient pressure
distribution in the canopy and its quick inflation. These openings are scaled
together with the ribs, so that their replicability is flawless and they do not
disturb the aerofoil in any way.
Another feature of the Coden is the Flexi-Egde
technology. The leading edge is closed to the airflow,
and its precise shape is kept with laminated cloth
reinforcements, incorporating synthetic rods. The rods
make the leading edge stiffer and smoother, bringing improvements in many
areas - from easier inflation, through stiffening the canopy in flight to
improved general airflow.
The intakes are located on the undersurface in the vicinity of leading edge.
Their position was chosen very carefully, so that they got maximum ram
effect in possibly many flight situations.
The wing tips additionally feature ACS (Auto Cleaning
Slots) – as the name suggests, these are dedicated
openings automatically removing dirt from inside the
canopy.
Careful selection of modern fabrics and design solutions brings about great
strength and durability of the Coden. All materials used come from marked
production batches, and each production step can be verified down to
identification of specific worker and controller.
Coden is manufactured under new technology, utilizing
precision of the laser cutter. All stages of production
process take place in Poland under strict supervision of
the designer himself, thus ensuring highest European
quality.

USER MANUAL

CLOTH
Each kind of cloth has its own special qualitites. We merged them so that
they blend into a perfect composition.
The upper surface is made of 38-gram Dominico Tex
cloth. Basically it's a nylon material, covered with PU
impregnate. Such covered fabric is not very stiff and -
what's most important - has increased tear, stretch
and UV resistance. It is not siliconised, so minor repairs can be easily made
with self-adhesive strips.
Lower surface is made of 34-gram Dominico Tex cloth, contributing to low
weight of the canopy.
The ribs must be as rigid and stretch-resistant as possible. We found these
qualities in Porcher Hard Finish cloth with E29A impregnate (40 g/m2). All
suspension points and leading edge reinforcements are made of SR-Scrim
fabric.
RIGGING
All of the Coden lines (including mains) are unsheathed. Because of low
number of the lines we made sure they are strong
enough by using Technora cores, featuring high
strength and stretch-resistance.
The rigging system consists of individual lines looped and stitched at each
end.
The upper level lines start at the attachment points. Cascade-wise they are
joined to main suspension lines, either directly or via middle layer lines. Main
lines are attached to the risers with triangular quick links (maillons). To
prevent their slipping off, the lines are kept together with a rubber 'O ring'
twisted in eight.
All maillons are made of corrosion resistant, polished stainless
steel, ensuring excellent strength and durability. We use only
the best quality, certified maillons by Peguet.
Stabilo lines run from the outer suspension points to the maillons through
consecutive cascades as well. The same story goes for the steering lines.
They run from the trailing edge through several layers to the main lines,
which are lead through the pulleys connected to the rear risers and then
fixed to the brake handles. Steering lines do not carry any load.
RISERS
Coden features two-way risers, equipped with:
+ELR (Easy Launch Riser) - This is a specially marked
A riser (yellow ribbon),
6

7
+speed-system affecting A and A' risers when engaged,
+ACB system (Activ Control B) – special steering toggles (red balls) for
B-risers steering.
Brake handles are attached to the steering lines at optimal point,
guaranteeing safe and effective operation. It is marked black on the main
brake line and this setting should not be changed. Fixing brake handles
above that point causes permanent braking of the paraglider which can
easily lead to an accident. Overly long brake lines are not advised either, as
total lack of strain can prove dangerous in some situations.
Our newest steering handle used in Coden, besides its attractive, light
design, features:
+Soft neoprene cover,
+a swivel to prevent possible twisting of the steering line,
+EK (Easy Keeper) system).
SPEED SYSTEM
The heart of speed system is a line sewn into A riser, running through two
pulleys and finished with a loop holding small hook. There you attach the
speed bar line. In normal flight all risers (including quicklinks) have an
overall length of 540 mm. Speed system affects risers A (with A') and B.
When the bar is being pushed, A and B risers are gradually shortened. C-
riser retains its original dimensions.
CAUTION: An improperly adjusted speed system renders the
certification invalid!
Speed system adjustment
Most of modern harnesses are equipped with special speed system pulleys
and sometimes even its own integrated speedbar. If it's not the case, first
you need to have some pulleys attached (at best sewn into harness) in such
a way that will allow the pilot maximize the output of his/her legs with correct
power vector, without effect of pushing the harness back.
The speed system cord must be firmly attached (with bowline or other non-
slipping knot) to the speed bar. The other end of the cord must be ran
upward through the harness pulleys, to be finished with hooks or small
carabiners. Overall length of speed system cord should allow pilot to put
his/her feet easily into the bar when in flight, and yet should be short enough
to cover the full speed range.
Make sure that both cords on the speed bar are equal, as even slight
difference can result in constant turning of the paraglider. Test your speed
system thoroughly on the ground before flying with it!
USER MANUAL

The maximum action is reached when speed system pulleys touch.
Speed system operation
Before take-off attach paraglider risers to the harness with main carabiners.
Then connect speed system cords with hooks or quick-links. Before
launching make sure that speed system is not tangled and runs freely.
To use the speed system simply place your feet on the speed bar and push
forward in a horizontal plane. If you notice loss of pressure on the bar, it can
be a sign of imminent frontal collapse. In this case release the bar
immediately. Watch out for such things - quick wits can spare you most
collapses and in general you will increase your awareness of the air around
you.
Speed system operation diminishes your paraglider's angle of attack, so that
its airspeed is increased. Yet simultaneously canopy becomes less stable -
that's why you should avoid using speedsystem in turbulent conditions,
close to the ground or near other airspace users!
Do not use speed system during extreme manoeuvres! If the canopy
does collapse, release the speed bar immediately and correct the
situation as usual.
When flying with speed system enagaged do not use main steering
handles, as it may cause the paraglider to be less resistant to
collapses. In such moments it is advised to steer with ACB system –
red balls placed on B risers.
WHICH HARNESS?
You can use any certified harness with hang point between 35 cm and 49
cm from the seat (the safest distance being 40 cm).
Width between carabiners should be somewhere between 37 cm and 45 cm,
still in this case the best option is 40 cm too.
Please note that any modification of seat/hang point distance changes the
position of the brakes in relation to the pilot's body. You must remember that
in each harness your typical steering range will be different.
CAUTION! Too tight cross straps can dramatically affect the handling,
so tightening them actually may not contribute to higher safety. Have
them always tightened just the correct amount.

3. FLIGHT
PRE-FLIGHT CHECK
A thorough pre-flight check is essential for any aircraft and the Coden is no
exception.
Having unpacked and laid out the paraglider (in a horseshoe directed
against wthe wind) following checks must be made:
+canopy, lines and risers condition. Do not launch if the slightest
damage is noticed,
+the paraglider should be arranged so that the centre section A-lines
(yellow risers) will strain earlier that the outer ones (A’ - blue risers).
This ensures easy and symmetrical launch,
+cells of the center section must be handled with special care, so that
leading edge stays taut and even,
+all lines and risers should be separated. Make sure they are not
tangled and pay special attention to the A-lines, which should run free
from the A (yellow band) and A’ risers (blue band) to the canopy,
+it is equally important to untangle the brake lines so that they will not
catch anything on the ground during launch. They must be firmly
attached to the brake handles and run freely through the pulleys to the
trailing edge,
+make sure the risers are not twisted,
+it is very important to check that no lines are looped around the
canopy. The so-called ”line-over” may have disastrous consequences
during take off.
Always put on and fasten your helmet before clipping in to the
harness.
Check quick links (maillons). Sometimes they can unscrew, especially
when the wing is new.
Check main carabiners. They must be properly mounted, closed and
locked.
LAUNCH
Classic (forward) launch
Should be used with little or no wind.
Facing the wind place the risers over your shoulders (A riser must lay on
top). Clip it into carabiners and lock them. Grip the brake handles and A-
risers (marked with yellow band), holding them at the stitching, just under
the quick-links. Spread out your slightly bent hands, keeping them down and
back. All risers but the A should be placed near your elbow joints.
USER MANUAL

Apply some tension to check if the A risers stay on top and the lines are not
tangled. Take a step back, bow down a little and run forward. After the initial
inflation smoothly move the hands with the risers up and over your head until
the wing will be directly above you. Check the wing and let the A risers loose.
Pump out possible faults and keep an eye on position of the paraglider.
Side drift is corrected best by moving yourself always under center of the
canopy (launch space permitting). In order to keep wing in the air the
suspension lines must stay taut all the time, so in light winds you will have to
run forward. With stronger winds you can control the wing while standing
still.
When leaving the ground apply some brakes, then release it after gaining
some distance from the ground. Keep your hands relaxed.
Reverse launch
To be used when wind speed exceeds 3 m/s. After clipping the risers into
carabiners as for the forward launch, turn back to face the wing, moving one
riser group over your head. As a consequence, you will have the risers
crossed.
Unclip the brake handles from rear risers and grip it outside of the risers
without crossing neither arms nor lines. In this way you steer the left side
with you left hand and vice versa. Now take corresponding A risers on both
sides (still keeping brake handles in your hands).
Make sure that the wing inflates symmetrically and the lines are not tangled.
Building up tension with a few steps back and simultaneously lifting the A
risers (do not pull them towards you) will make the paraglider rise. When it
arrives over your head, stabilize it with the brakes, check again if all lines are
clear and the cells inflated.
When turning into wind, remember to turn the right way (hint: always do it
the same direction) and to keep the lines taut (loaded) at all times. The turn
itself should be quick and smooth. While turning you have to release the
brake handles and grip them again facing forward. Last check of the wing &
free space to launch and off you go, running into wind with eventual light
braking when taking off.
CAUTION: when deflating the canopy in strong winds (e. g. aborting a
launch), use the B risers, not the brakes. Using the brakes in strong wind
can lift the pilot up and drag him/her back.
TURNS
Coden is an agile wing, with smooth reactions to the steering inputs.
Handling is actually easy and forces grow proportionally to position of the
brakes. Adding some weight shift will make the paraglider turn really quick
and tight.
