2.5.2. Changing the riser cords
IIn spite of the speed system having pulleys with bearings to reduce
friction to a minimum, the frequency with which the speed-bar is used
causes the cord to wear and you may need to replace them.
In all Niviuk gliders the speed system cords on the risers are completely
removable and easily replaceable. You can use the Brummel hooks, not
use them, remove them, use another type of connector, etc. It is even
possible to fix the speed-bar cords directly to the speed system on
the risers. This last option makes the connection / disconnection more
laborious, but means the cord has maximum travel without obstructions
or restrictions which is very useful for some models of harnesses.
2.6 TRIMMERS
Using the trimmers:
the trimmers are an adjustable profile modification system. They are
activated by releasing the trimmers. To open the trimmers, press the
trim tab inwards until the tape is released. Release the tape until it is in
the desired position. When the trim tab is no longer pressed, the tape
is locked in that position. Colloquially this is known as “releasing” or
“opening” the trimmers.
Once it is locked in that position, it will not release automatically and
return to its initial position. The pilot is solely responsible for opening and
closing the trimmers.
To close the trimmers, pull the tape down using the handle - without
touching the trimmer tabs. Release the handle when you reach the
required position. Colloquially this is called “closing” the trimmers.
The trimmers must be applied symmetrically.

Take off
Thanks to the profile of the KOUGAR 3, all aspects of take off can be
controlled using the trimmers.
The SLE system optimally positions the cells openings of the leading
edge and thus assuring the rapid formation of the wing profile. This
contribution is in itself already a huge advantage when attempting to
take off in nil wind conditions, but the correct use of the trimmers at this
time will further facilitate an easy take-off. In nil wind and without the
application of trimmers the KOUGAR 3 inflates easily and effortlessly.
However, by adjusting the trimmers we can control both the inflation and
the speed at which the wing rises. We should not confuse the speed of
the inflation with the speed of the forward run required. It is important to
remember that the minimum take-off speed is achieved with the trimmers
closed and as the trimmers are opened more speed will be required.
Therefore every pilot should be aware of the trimmer settings and make
any necessary adjustments appropriate to the conditions, the terrain and
pilot skill.
In flight
The trimmers on the KOUGAR 3 are highly and precisely adjustable,
allowing the pilot to either increase speed by opening the trimmers or
conversely decrease speed by closing them.
The KOUGAR 3 is a precise, fun machine, capable of gliding when the
engine is almost idle. All this whilst being able to use the brakes at any
