Niviuk KOYOT 4, User Manual

and turbulent conditions it remains stable and solid.

The KOYOT 4 flies efficiently. It enters thermals with sufficient speed to 
centre in the lift and climbs progressively.  The handling is progressive 
and effective for even more flying pleasure under an exciting wing of 
extraordinary quality.   

It is lightweight; even lighter in flight and easy to pilot, with outstanding 
turbulence buffering and a surprising range of speed for incredible glides.

1.4 ASSEMBLY, MATERIALS

The paraglider has all the technological innovations used on other Niviuk 
gliders and is built with the most careful selection of current materials. It 
has all the current technology and accessories available to improve pilot 
comfort whilst increasing safety and performance.
In the design of all Niviuk products the team aims to ensure development 
and continuous improvement. The technologies developed in recent 
years have allowed us to develop greater, better wings. It is in this 
context that we would like to introduce the technologies included in this 
new model. 

RAM Air Intake 

- this 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 flow at all angles to improve laminar flow. More consistency across 
the whole speed range and better performance without compromising on 
safety.

Titanium Technology (TNT)

 - a revolutionary technique using titanium. 

Using Nitinol in the internal construction provides a more uniform profile 
and reduces the weight to gain efficiency in flight. Nitinol provides the 
highest level of protection against deformation, heat or breaks. The 
leading edge is more rigid and the wing surface remains perfectly taut, 
without creases or parasitic drag.  This optimises glide in all phases of 

the flight.  Because the flexible rods always return to their original shape, 
the integrity of the profile is never affected.  Nitinol provides the highest 
level of protection against deformation, heat or breaks.

Structured Leading Edge (SLE)

 - the use of the SLE considerably 

reduces the amount of Mylar which was used in previous Niviuk wings 
and this also reduces the weight of the leading edge. Therefore it is 
easier to inflate this wing than a paraglider without this system.

3D Pattern Cut Optimisation (3DP)

 – the latest generation of wings 

require a new fabric panel pattern and cutting system. Creating separate 
panels for each of the sections at the front of the wing means the sail 
fabric is more taut and crease-free. During the cutting, the optimal 
orientation of the fabric section is selected, depending on its final 
location. If the fabric pattern is properly aligned with the axes of load, it 
suffers less deformation after repeated use, to the long-term benefit of 
the leading edge.

3D Leading Edge (3DL)

 - adding an extra seam to the longitudinal 

axis of the glider helps, on the one hand, give more consistency and 
volume to the profile (a more efficient 3D contour) and on the other, joins 
and shapes the leading edge panels. The fabric is guided by the panel 
position to ensure fewer creases and better load distribution. The result 
is a cleaner profile, which benefits the wing in terms of performance and 
durability.

The use of these technologies is a big technological leap forward in 
building wings and a big improvement in flight comfort. 

For the construction process of the KOYOT 4 we use the same criteria, 
quality controls and manufacturing processes as in the rest of our range. 
From Olivier Nef’s computer to fabric cutting, the operation does not 
allow for even a millimetre of error. The cutting of each wing component 
is performed by a rigorous, extremely meticulous, automated computer 
laser-cutting robotic arm.
