Niviuk KOYOT 4, User Manual

8

• To connect it to the harness, please follow the instructions of the 
harness manufacturer. The majority of harnesses have a speed system 
pre-installed. 
• The standard connection of the speed-bar to the speed system is via 
Brummel hooks, where two slots in the hooks are interlocked, making 
their connection / disconnection easy. However, any connection system 
that is safe may be used.

2.5.2  CHANGING THE RISER CORDS.

In 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 INSPECTION AND WING INFLATION ON THE GROUND

After your gear has been thoroughly checked and the weather conditions 
deemed favourable for flying, inflate your KOYOT 4 as many times as 
necessary to familiarise yourself with its behaviour. Inflating the KOYOT 
4 is easy and should not require a great deal of physical effort. Inflate 
the wing with a little pressure from the body using the harness. 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 inflated to the 
overhead position, appropriate control with the brakes will be sufficient to 
hold it there.

2.7 ADJUSTING THE BRAKES

The length of the main brake lines are adjusted at the factory and conform 
to the length stipulated during certification.   However, they can be 
changed to suit your flying style.   It is advisable to fly with the original 
setting for a period of time to get used to the actual behaviour of the 
KOYOT 4 . In case it is necessary to modify the brake length, loosen the 
knot, slide the line through the brake handle to the desired point and 
re-tighten the knot firmly. Only qualified personnel should carry out this 
adjustment. You must ensure that the modification does not affect the 
trailing edge and slow the glider down without pilot input. Both brake lines 
should be symmetrical and 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. It is important 
to check that the brake is adjusted to take into consideration this extra 
distance during acceleration. With this profile deformation there is a risk of 
generating turbulence and causing a frontal or asymmetric collapse.
