1. CHARACTERISTICS
1.1 WHO IS IT DESIGNED FOR?
Targeted at experienced paramotor pilots with extensive ying
experience and proven skills, who wish to have a very fast and accurate
wing for slalom, classical or freestyle competitions or for recreational
ights, who do not wish to sacrice comfort and safety.
Paramotoring is a relatively new discipline and it is continuously evolving.
To get the most out of the wing, it is essential that the motor set-up,
propeller, harness and pilot experience are compatible.
Only the aeronautical authorities of respective countries can determine
the pilot competence.
1.2 CERTIFICATION
The DOBERMANN 2 complies with the requirements of EN 926-1.
The load and traction tests were conducted by the Air Turquoise testing
centre in Switzerland.
Shock test to 1.200 kg.
Load test to 8G 148 kg.
Load test (calculated by DGAC) to 5.25G 225 kg.
Load test report EN 926-1:2015 & LTF NFL 91/09 chapter 3.
It has passed the Dirección General Aviación Civil (DGAC) certication as
ULM class 1. It also has the manufacturer’s certication.
Any modication of the paraglider invalidates the certication.
Note that each wing size can behave differently during the same
manoeuvre depending on its all-up weight.
1.3 IN-FLIGHT BEHAVIOUR
Niviuk developed the DOBERMANN 2 by adopting very specic
guidelines: the objective was to seek utmost performance: faster,
steadier and better in turns. Better feel for the wing and easier piloting.
The glider prole was optimised to provide feedback in a very
understandable and convenient way, helping the pilot concentrate on the
feel of the wing and their technique.
In all aspects of ight the prole is very solid, smooth in glide, during
acceleration, deceleration, turns and counter-turns. When accelerating,
the wing augments the engine power. Whether accelerating from
fast to very fast, from acceleration to turn, turn to turn, turning to
acceleration, the wing remains compact and stable. The high-speed tip
improves the turn precision and is therefore less physical and provides
better feedback. Inating the wing is much easier and gentler without
overshooting.
PLEASE NOTE!
For high-speed ying, it is very important to become familiar with the
correct use of the main steering elements: the trimmers, accelerator
(DES), High-speed tip steering and the main brakes. At high speeds any
action is immediately implemented and if the decision is incorrect, this
can have grave consequences for the pilot.
We recommend paying particular attention and concentration when
using these steering elements. See also the section on the Double
Steering System.
1.4 ASSEMBLY, MATERIALS
The DOBERMANN 2 has all the technological innovations used on other
Niviuk gliders which are designed to enhance the pilot’s comfort and to
improve the performance of the wing.
Titanium Technology (TNT) .- A revolutionary technique using Nitinol,

5
developed to build the internal structure of the glider, brings a more
uniform prole, and hence reduces the overall wing weight to gain
efciency in ight. The Nitinol provides the highest level of protection
against deformation, heat or breaks. Using this technological advance,
the glider is able to maintain its original features for a longer period of
time.
Double Effect System (DES) .- With the implementation of the DES,
pilots can make the most out of the glider’s ability to perform to its full
potential using the speed bar. The DES keeps the trimmers in the default
closed position (the slowest) and will open them when accelerating
during the ight. When the speed-bar is released the DES brings the
prole back to the neutral and default position.
Structured Leading Edge (SLE) .- The use of the SLE allows
reinforcement of the leading edge, preventing any deformation in
turbulence. The airow is also vastly improved over the entire leading
edge of the glider.
Reflex System Profile (RSP) .- Unlike conventional reex designs,
the highly efcient Reex System Prole requires less engine power to
achieve greater thrust, thus resulting in lower fuel consumption, more
autonomy and higher overall motor efciency. The RSP prole improves
gliding, speed and safety.
3D Leading Edge (3DL) .- Adding an extra seam to the longitudinal axis
of the glider helps building a cleaner prole with fewer creases and better
load distribution.
3D Pattern Cut Optimisation (3DP) .- Cutting thefabric in a specic
directional angle according to each panel’s nal location and positioning
results in a crease-free surface with better fabric tension.
RAM Air Intake (RAM) .- The RAM Air Intake system is characterised
by the arrangement of the air inlets, to ensure optimal maintenance
of internal pressure. Thanks to this design, we were able to reduce
their size, while maintaining the same air ow at all angles to improve
laminar ow. Having greater internal pressure means better absorption
of turbulence, greater consistency of the prole across the speed
range, excellent handling at low speed is achieved by allowing the
pilot to extend the braking limit, there is a lower risk of collapse and
consequently, greater control and stability.
Double Steering System or High-speed tip steering is a simple and
effective tool for the pilot to turn effortlessly without touching the brake,
effectively preventing deformation of the prole and therefore preventing
a decrease in performance and speed.
From Olivier Nef’s computer to fabric cutting, the operation is a Zero
6 tolerance process. An automated computer laser-cutting robotic
arm creates each of the many sections needed to complete the wing
assembly. This program also paints the guideline markers and numbers
on each individual fabric piece.
The jigsaw puzzle assembly is made easier using this method and
optimises the operation while making the quality control more efcient.
All Niviuk gliders go through an extremely thorough and detailed nal
inspection.
The fabric used to manufacture the glider is light, resistant and durable
and there will be no colour loss.
The DOBERMANN 2’s line cascade layout uses an analysed combination
of Dyneema and Vectram in order to support the load, depending on the
location of the line area.
The lines are semi-automatically cut to length and all the sewing is
completed under the supervision of our specialists.
Every line is checked and measured once the nal assembly is

6
concluded. Each wing is then individually inated for the last visual
inspection.
Each glider is packed following specic maintenance instructions as
recommended by the fabric manufacturer.
Niviuk gliders are made of premium materials. Information about the
various materials used to manufacture the wing can be viewed on the
nal pages of this manual.
1.5 ELEMENTS, COMPONENTS
The DOBERMANN 2 is delivered with a series of accessories that,
although not fundamental, are important in the use, transport and storage
of the paraglider.
- The Koli Bag, ideal for packing all the equipment.
- An inner bag making the glider folding process easier.
- An adjustable folding strap for quick and easy packing.
- A small fabric repair kit with self-adhesive ripstop nylon (matching the
wing’s colour scheme) and replacement O-rings.
2. UNPACKING AND ASSEMBLY
2.1 CHOOSING THE RIGHT LOCATION
We recommend unpacking and assembling the wing on a training hill or
a at clear area without too much wind and free of obstacles. It will help
you to carry out all the recommended steps required to check and inate
the DOBERMANN 2.
We recommend that a qualied instructor is present to supervise the
entire procedure, as only they can resolve any doubts in a safe and
professional way.
2.2 PROCEDURE
Take the paraglider out of the rucksack, open and unfold it on the ground
with the lines positioned on the undersurface facing the sky. Lay out the
wing in a crescent shape with the cells openings pointing into wind, as if
you were to inate it.
Check the condition of the fabric and the lines for defects. Pay attention
to the maillons connecting the lines to the risers to make sure they are
fully closed and tightened. Identify, and if necessary untangle, the A, B,
C and D-lines, the brake lines and corresponding risers. Make sure that
there are no knots.
2.3 CONNECTING THE MOTOR
Correctly connect the risers to the harness’ carabiners. The risers and
lines must not have any twists and must be in the right order. Check that
the harness buckles are properly fastened and securely locked.

Check the paramotor manufacturer’s specication on attachment points.
2.4 HARNESS TYPE
The DOBERMANN 2 can be own with most harnesses on the market.
The distance/comfort bar will determine the distance between the
carabiners. Incorrect chest strap adjustments can affect glider/harness
behaviour and thus glider handling. Too wide a distance between the
carabiners will provide greater feedback from the wing, but less glider
stability. Too narrow a distance will not provide as much feedback, as well
as increasing the risk of experiencing a riser twist during a collapse.
2.5 SPEED SYSTEM ASSEMBLY
The speed system of the DOBERMANN 2 works when you push with

7
your feet on the accelerator bar/speed-bar, which is NOT supplied with
the equipment.
Most harnesses are equipped with a pre-installed speed system. Before
rst use, ensure that all the harness’ pre-installed components, such as
the pulleys, are installed correctly. After tting, take into account that you
will have to adjust the length of the speed-bar lines for your individual
requirements. This will vary according to the length of each pilots’ legs!
PLEASE NOTE!
Please ensure you carefully read the sections on trimmers and the
Double Effect System (DES).
We recommend testing the accelerator system when hanging in a frame
rst - most schools have such equipment. If in doubt, seek advice from a
qualied professional dealer or school.
2.6 INSPECTION AND WING INFLATION ON THE GROUND
After your gear has been thoroughly checked and the weather conditions
deemed favourable for ying, inate your DOBERMANN 2 as many times
as necessary to familiarise yourself with its behaviour. The DOBERMANN 2
inates easily and smoothly. An excess of energy is not necessary and the
wing will inate with minimum pressure on the harness when you move
forward. This may be assisted by using the A-lines.
Do not pull on them; just accompany the natural rising movement of
the wing. Once the wing is in the 12 o’clock position, simply apply the
correct pressure on the brake lines and the DOBERMANN 2 will sit over
your head.
2.7 ADJUSTING THE BRAKES – DOUBLE STEERING SYSTEM
The length of the main brake lines is adjusted at the factory. However, it
can be changed to adapt to the pilot’s own ying style. In any case, we
recommend ying for a while using the default line length factory settings
before making any adjustment. It will enable you to become more familiar
with the DOBERMANN 2 and its unique ying characteristics. If you then
decide to change the length of the brake lines, untie the knot, slide the line
through the brake link to the desired length, and re-tie the knot so that it is
tight. Only qualied personnel should carry out this adjustment. You must
ensure that the modication does not slow the glider down without pilot
input. Both brake lines should be symmetrical and of the same length. We
recommend using a clove hitch or bowline knot.
When changing the brake length, it is necessary to check that they do
not engage when the speed-bar is used. When we accelerate, the glider
rotates over the C riser and the trailing edge elevates. We must check that
the brake is adjusted to take into consideration this extra distance during
acceleration.
PLEASE NOTE!
The main brakes and the high speed tip are connected at the same point.
Special care must be taken when adjusting the brakes or the high speed tip.
Frequently, pilots decide to adjust the two differently.
Please see the section on: Using the high speed tip
2.7.1 ADJUSTING THE BRAKE PULLEY
Because of the different harness heights that engine manufacturers use,
the DOBERMANN 2 has the possibility of moving the brake pulleys,
depending on the height of the harness or just for pilot convenience.
The pulley is fastened to the riser using velcro and can be adjusted
easily. The riser has 4 possible xing points (distributed along 10 cm) to
accommodate the pulley.
PLEASE NOTE!

8
Only the brake line should pass through the pulley – never the high
speed tip.
3. THE FIRST FLIGHT
3.1 CHOOSE THE RIGHT LOCATION
The rst ights with the DOBERMANN 2 should be made in low wind
speeds, on a training hill or obstacle free area. We recommend that a
qualied instructor is present and supervising the entire procedure.
3.2 PREPARATION
Repeat the procedures detailed in chapter 2 UNPACKING AND
ASSEMBLY to prepare your equipment.
3.3 FLIGHT PLAN
Planning a ight before taking off to avoid possible problems later is
always a good idea.
3.4 PRE-FLIGHT CHECK LIST
Once ready, but before taking off, conduct another equipment inspection.
Conduct a thorough visual check of your gear with the wing fully open,
the lines untangled and properly laid out on the ground to ensure that all
is in working order. Be certain the weather conditions are suited for your
ying skill level.
3.5 WING INFLATION, CONTROL AND TAKE-OFF
Smoothly and progressively inate the wing (see chapter 2.6
INSPECTION AND WING INFLATION ON THE GROUND). The
DOBERMANN 2 comes up easily, without excessive energy and does not
overy the pilot. It is a straight forward exercise leaving enough time for
the pilot to decide whether to run and take off or not.
Whenever the wind speed permits, we recommend using a reverse
launch technique, as it is more conducive to carrying out a better visual
check of the wing. The DOBERMANN 2 is especially easy to control
during reverse inations in windier conditions. However, wind speeds up
to 25 to 30 km/h are considered strong and extra consideration should
be given as whether or not to y.
Setting up the wing on the ground before takeoff is especially important.
Choose an appropriate location facing the wind. Position the paraglider
in a crescent conguration to facilitate ination. A clean wing layout will
ensure a trouble free take-off.
3.6 LANDING

9
The DOBERMANN 2 lands excellently, it transforms the wing speed into
lift at the pilot’s demand, allowing an enormous margin of error. You
will not have to wrap the brake lines around your hand to get greater
braking efciency.
3.7 FOLDING INSTRUCTIONS
The DOBERMANN 2 has a complex leading and trailing edge,
manufactured using a variety of different materials. A correct folding
method is very important to extend the useful life of your paraglider. It
should be concertina-packed, with the leading edge reinforcements at
and the Nitinol exible rods stacked one on top of the other. This method
will keep the prole in its original shape and protect the integrity of the
wing over time.
The wing should then be folded in three parts without excessive
compression; the contrary could lead to material and/or the line damage.
The NKare bag is an easy to use folding bag designed to help with the
packing process. It can also be used as a surface base to protect the
glider against damage.
4. IN FLIGHT
Note that glider behaviour can vary, depending on size or wing loading
for the same size.
The performance and speed of the DOBERMAN 2 depend directly on the
engine power, the use of DES and wing loading.

INTERMEDIATESMOOTH
With the RSP (Reex System Prole) the engine does not need much
power to achieve a greater thrust, resulting in less consumption, more
autonomy, less need for power, durability, mechanical efciency and
increased performance.
However, in order to get the maximum power out of this wing, we will
need an engine that is able to push a highly loaded wing. Without the
right wing loading and without the required power, the wing will not
operate to its full potential.
Please remember! The DOBERMANN 2 is a competition wing with a DNA
capable of great feats but it must be handled correctly or it may cause
serious problems for the pilot.
4.1 DES (Double Effect System)
Pilots who y the DOBERMANN 2 must realise that this wing was
designed as a competition wing. All its elements have been designed for
speed and to stay at the front of the competition. The wing can be used
for recreational ights, but the pilot must be aware of the potential of this
wing and adjust their ying style accordingly.
Because the wing can y at great speeds, the pilot must make quick and
assertive decisions.
The DOBERMANN 2 is delivered with the DES (Double Effect System)

10
already installed.
The system should only be used by very experienced pilots.
Using this technology without sufcient skill and experience carries great
risk to the pilot. Its use near terrain requires great skill and can leave the
pilot with very little room for manoeuvre in the event of an incident.
In a slalom competition, the pilot needs to enter the circuit with maximum
speed, then reduce speed quickly, while initiating the turn to round the
pylon and set the course to the next turning point, accelerating again to
full speed. All this in just a few seconds!
The pilot must also manipulate the throttle, trimmers, gas and control the
rotation – this required a solution that would allow the pilot to act quickly
and effectively. The DES was designed to full this requirement.
The DES provides an alternative, allowing the pilot to accelerate to
100%, reduce speed and return to 100% in the shortest possible time, in
a single movement.
The DES interactively connects the throttle with the trimmer, allowing
acceleration and the opening of the trimmers in one movement of one leg
while the hands are free for the throttle and turning system (see High-
speed tip steering).
With the DES, the pilot has available an accelerator which can unleash
the full power of the wing, and they can utilise accurately and quickly the
speed that is required at all times. The DES means the wing launches
with the neutral (slowest) setting and as it accelerates, it releases the
trimmers. At its peak, the pilot can use 100% accelerator and 100% of
the trimmers with the wing working with the reex to 100% When you
release the accelerator, the DES is responsible for returning the prole to
neutral.
The pilot can adjust the amount of trimmer to be released, even during
ight. It is not always necessary to accelerate to 100% and open the
trimmers 100%. The pilot can choose the proportion of trimmer to use.
Given that only when the accelerator is at 100%, the trimmer will be
opened to the maximum.
With the DES installed, the classic trimmer function is cancelled as this is
subordinate to the accelerator.
The pilot can leave the trim in neutral and only use the accelerator.
PLEASE NOTE!
We recommend you do not disable the DES. The DOBERMANN 2 is
designed to y with the DES installed. It is possible to disable the DES
but in this case, the pilot must not engage the trimmers in ight. The
standard trimmers will not function without the DES.
PLEASE NOTE!
With 100% accelerator and 100% trimmers we recommend not using the
brakes as this makes the wing more prone to collapses.
It is of utmost importance that the pre-ight check routine includes
checking that the DES link is connected to the two bands. Also that the
trimmers are set symmetrically.
4.2 DOUBLE STEERING SYSTEM
In increase the turning efciency, the DOBERMANN 2 is tted with the
Double Steering System.
The DOBERMANN 2 has two brake lines: the main brake and the high
speed tip. The high-speed tip gives the pilot the ability to turn without
pulling the brakes, thus avoiding deforming the prole and therefore
preventing a decrease in performance and speed.
