2.3 CONNECTING THE HARNESS

The KOYOT 4 risers are colour-coded.  
- Right: green
- Left: red 

This colour-coding makes it easier to connect the wing to the correct 
side and helps prevent pre-flight errors.

Correctly connect the risers to the attachment points so that the risers 
and lines are correctly ordered and free of twists. Check that the IKS or 
carabiners are properly fastened and securely locked.

2.4 TYPE OF HARNESS

The KOYOT 4 can be flown with all current harness types. We recommend 
setting the chest strap to the distance specified in the certification report - 
this will vary depending on size.

Care should be taken with the chest strap setting, as the distance of the 
chest strap setting will affect the handling of the glider. If the chest strap is 
too wide, it allows greater feedback but this carries the risk of affecting the 
stability of the wing.  
If the chest strap is set too tightly, the wing feels more solid, but there is a 
loss of feedback and a risk of twisting in the case of a violent asymmetric 
collapse.

2.5 SPEED-BAR

The speed-bar is a means of temporary acceleration by changing the 
flow over the profile.  The speed system comes pre-installed on the risers 
and is not modifiable as it conforms to the measurements and limits 
stipulated in its certification.  

The KOYOT 4 includes a speed system with maximum travel depending 

on its size (see below). 
The speed system is engaged when the pilot pushes the speed-bar 
-  included as standard with this glider model - with their feet (see 2.5.1  
Speed system assembly)

The speed system uses an action/reaction system. Released, the speed-
bar is set to neutral. When the bar is pushed using the feet, the wing 
accelerates. The speed can be regulated by varying the pressure on the 
bar. Once the pressure on the bar is released, the speed system returns 
to the neutral setting. 

The speed system is efficient, sensitive and precise. The pilot can use the 
system whenever they want during the flight. In the neutral position the 
glider will fly at the standard speed and glide. Using full speed-bar, the 
wing will fly at maximum speed, but the glide will be adversely affected.  

•Released speed-bar: the A, B, C and -risers are aligned.

•In all sizes, the maximum travel of the speed-bar is 130 mm.

PLEASE NOTE!
The use of the speed system results in changes to the speed and reactions of 
the wing. For more information, please see the certification report.

2.5.1 SPEED SYSTEM ASSEMBLY.

The speed-bar consists of the bar that the pilot pushes with their feet, as 
well as the two cords that connect it to the speed system components 
on the risers. Once you have chosen the type of speed-bar you prefer, 
you must install it. Some considerations:

• you should use the type of speed-bar you consider appropriate, 
depending on the type of harness, personal preferences, etc. 
• The speed-bar is detachable to facilitate its connection and / or 
disconnection to the risers as well as subsequent adjustment.
