introduction

Congratulations!

We are pleased to welcome you among the growing number of
DUDEK PARAGLIDERS pilots. You’ve become a proud owner of a
sport paraglider, designed according to recent trends.

Intensive development, application of the modern production
methods and thorough testing resulted in a friendly behaving
paraglider, offering the pilot a lot of fun combined with great
performance.

We wish you many enjoyable and safe flying hours.

Please read this manual carefully and note following details:

< The purpose of this manual is to offer guidelines to the pilot

using the paraglider. By no means it is intended to be used as a
training manual for this or any other paraglider.

< You may only fly a paraglider when qualified to do so or when

undergoing training at an accredited school.

< Pilots are personally responsible for their own safety and their

paraglider's airworthiness.

< The use of this paraglider is solely at the user's own risk! Neither

the manufacturer nor dealer do acceptany liabilities involved.

< This paraglider on delivery meets all the requirements of the EN

926-1 and 926-2 regulations or has an airworthiness certificate
issued by the manufacturer. Any alterations to the paraglider
will render its certification invalid.

< Other documents concerning this paraglider can be found on

attached pendrive or on our website: www.dudek.eu.

NOTE: Dudek Paragliders warns that due to the constant

!

process of development the actual paraglider may differ
slightly from the one described in the manual.
However, those differences must not affect the basic design
parameters: technical data, flight characteristics or strength.
In case of any doubts contact us please.

on the wing

For whom the Run&Fly?

We’ve designed the first ever wing under 1 kg (986g), meaning it’s
the lightest and most compact aircraft of the world. It is much more
intuitive than a normal paraglider, at an affordable price at that.

The Run and Fly is not a typical paragliding canopy: it has a single skin.
Therefore it’s lighter while displaying much stronger tendency to stay
over head and recover from any surges than a regular paraglider. In this
way, the Run&Fly offers safe take-offs, great maneuverability in flight and
smooth landings. It is exceptionally light, so that you can carry the wing
on your back during trail running or climbing sessions almost without
noticing the load. It is so compact, that it fits in a 4-litre bag. The Run and
Fly is perfect for trail running, hike & fly and necessary travelling, or just
as a second wing you will always have with you (you can easily place it in
your hand luggage while travelling by plane).

DESIGN

Designed by JB Chandelier, Team Dudek and Jacques Peugeot (airframe
sizing engineer), in close collaboration with Porcher Sport, the Run&Fly
project had been a real challenge for us. We decided to set ourselves
very aggressive goals in order to propose a really different, outstanding
product. The main specifications were a total weight below 1 kg (the
internal project name was 999gr), with speed and flare comparable to
standard wings. The wing also had to be affordable, in order to give

access to the sky to a wider public. With such an ambitious target, we
knew we couldn’t simply “make another single skin wing”: we had to
think out of the box. As a result, the Run&Fly needed hours and hours of
engineering discussions, debates, analyses, comparisons and numerical
simulations, then obviously completed with a lot of flight & load tests.

Ultimately, the wing turned out to exceed our expectations. The biggest
mono skin problems have been resolved; Run&Fly has good speed, nice
landing and offers a lot of fun. Besides reaching our goals we also
achieved a good glide ratio - above 6. Although we usually avoid
publishing the glide ratio of our paragliders, because this parameter is
sometimes subject to manipulation, we made an exception with Run &
Fly. We want to give potential pilots at least a rough understanding of
what they can expect from the fact that such an innovative wing exists.

IMPORTANT: Run&Fly belongs to the single-surface canopy

!

class. There is fundamental difference between classic double skin
and modern single skin canopies. All the launch, landing and
steering techniques look a bit different. If you are an established
paraglider pilot, you shouldn’t have any problems with adapting
to the wealth of new possibilities brought to you by the Run&Fly.
However, this doesn’t work both ways: if you started your
paragliding experience with the single-skin gliders, be aware that
you are not qualified to safely fly standard double-surface
canopies.

Run&Fly is produced in new technology, utilizing capabilities of
precise laser cutter. All stages of the production process take
place as our Polish plant under close supervision of the designer
himself, thus ensuring highest European quality.

Careful selection of modern fabrics and design solutions brings
about great strength and durability of the canopy. All materials
used come from marked production batches, and each
production step can be verified down to identification of
individual worker and controller.

riser scheme

The Run&Fly features four-way, extremely light risers, equipped
with:

<

DBS (D Brake System) – additional steering lines,
led through guides attached to D risers.
The system is there to help obtain better
flare and soft landing.

<

BEA (Brake Elastic Attachment)
– elastic parts fixing the brake
handles to respective risers
(instead of magnets).

Brake handles are attached to the steering lines at an optimal point,
guaranteeing safe and effective action.This point is marked on the
line with a black dot and this setting should not be altered.
Attaching the handles above factory markings will cause constant
braking of the paraglider, possibly cause
of an accident. Overly loose setting of the brake lines is not
advised too, since the much lower load on the trailing edge lines
can sometimes be dangerous too.

For quick and easy recognition in emergency, some of the risers are
distinguished with coloured covers as follows:

before first use

Operation

It’s pilot responsibility to choose a canopy matching his skills.

Dudek Paragliders cannot take responsibility for a wrong choice,
but we are always ready to advise you – just contact us.

Weight range

Each size of the Run&Fly paraglider is dedicated for a
corresponding pilot skill level. In this case a calculation of real take­off weight is necessary before using the size selection table, shown
below:

load [kg]

For the Run&Fly, the generale rule of selection says: the better pilot
skills, the bigger wing load is acceptable. With the wing load, the
speed and agility (response to steering inputs) grow accordingly.
The structural strength certificate of the Run&Fly is valid up to 105
kg take-off weight. This mass cannot be exceeded.

CAUTION: Check your real take-off weight! Some pilots

!

calculate their take-off weight by just summing up catalogue
numbers, e.g.: harness 5 kg + canopy 6 kg + pilot 89 kg =
ca. 100 kg. In reality your actual take-off weight can be
umpteen kilograms more. Most often we forget the clothing,
electronics, backpacks, sometimes even such basic things
like fuel or rescue chute weight are omitted!

What harness?

You can use any certified harness which has its hangpoints at 40-45
centimeters from the seatplate.The width between carabiners
should be somewhere between 40 cm and 45 cm. For the Run&Fly
we suggest using a light harness with separate leg placing, as this
increases stability and somewhat limits the amount of kinesthetic
sensations affecting pilot’s body.

CAUTION: Please note that any modification of seat/hang

!

point distance changes the position of the brakes as related
to pilot's body. You must remember that in each harness
your steering range will be different.

Other systems

This paraglider has no other systems which can be adjusted,
exchanged or removed.

Pre-flight check

Having chosen a place to launch accordingly to the terrain as well
as wind speed and direction clear it of any obstacles that could
damage your canopy or tangle in the lines.

After laying out your paraglider in a horseshoe directed against the
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 will strain earlier that the outer ones. This ensures
easy and symmetrical launch,

< the leading edge should stay taut and even,

< all lines and risers should be separated. Make sure they are

not tangled, and checked against catching anything. It is
equally important to check the brake lines. 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. Coloured hangpoint

covers will help you clip the risers to the carabiners correctly,
