higher than that of comparable Aramid lines, and they are completely insusceptible to bending-
cycle damage, unlike Aramid lines.
Line system
The entire line system is formed from individual lines, which are sewn and looped at both ends.
The single line levels are connected over a special hoop technology (the "handshake" loop) to
prevent a weakening of the core and a loss of strength. The lines and stitching are subject to
rigorous production controls, to ensure high and consistent manufacturing quality.
The lines of each wing section consist of four groups and the brake lines:
A-Level: AI, AII, AIII
C-Level: CI,CII, CIII
Brake lines : BRKI
The brake lines are collected at one main control line per side. This control line runs through a
pulley attached to the C-Riser and is marked with a black dot at the point where it should be tied
to the brake handle swivel. The brake is pre-set so that the glider is at 0 degree brake when the
toggle is free. Please don’t change the main brake lines without checking the new length carefully
at a suitable training hill before flying!
The line bundles of each level are looped together and attached to delta quick links, which are
connected to the risers. The quick links have special line collectors to prevent lines slipping.
Risers
In order to accommodate different pilot sizes the Guru risers are lenght-adapted to the canopy
size S, SM has shorter risers than M, L. This little detail improves the ergonomics of the wing
and makes all the different manoeuvres (Launch, BigEars, etc.) more accessible to every size of
pilots, from the smallest to the tallest. The speed system is optimised along the same lines. They
allow for very high top speeds with low sink values and give impressive stability at high speeds.
Once activated the speed system pulls simultaneously on the AI,II and AIII. This maintains the
angle of incidence around the leading edge and causes only minimal influence to the collapse
resistance properties of the wing. Top speed is reached when the top pulley touches the bottom
pulley of the speed system, down near the karabiner.
