strengthening them in these crucial spots.
The line layout is simple, with three levels
(A, B and C) plus brake lines. All line
splicings are sewn, and the looping is
done using the familiar Larks Head knot –
this assembly method reduces the strain
on the loops and the risk of tensile
strength reductions over time. The finished
lines, including stitches, are under
rigorous and continuous control at the
assembly line, assuring the high quality
levels always associated with UP
products.
Each glider ½ has the following line
layout:
A-level: AI-AIII
B-level: BI-BIII
C-level: CI-CIII (Stabilo)
Brake lines
The individual brake lines are gathered in
one main brake line which travels through
a low-friction pulley mounted on the rear
(C) riser. The main brake line has a mark
to show where the brake handle is
attached by factory default.
All main lines 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, and are secured
using a strong thread-locking compound
(Loctite©), to prevent unintentional
opening. After maintenance work the delta
quick links should be re-glued with thread
locking Loctite©!
Risers
Standard configuration of the Trango X-
light² is a riser with 12mm webbing.
The split A-risers and B-risers are
colour marked/colour-coded:
A-risers: Red
B-risers: Blue
C-risers: Black/no marking
In order to accommodate different pilot
sizes the Trango X-light² risers are
lenght-adapted to the canopy size – S
and SM have shorter risers than M and
L. This little detail improves the
ergonomics of the wing and makes all
the different manoeuvres (b-line, Big
Ears) more accessible to the pilots.
The speed system is optimised along
the same lines. Please notice that
there are 3 different riser
configurations for the different glider
sizes to insure the maximum
accelerated speed range.
Once activated the speed system pulls
simultaneously on the A's and B's.
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 extremity of
the speed system, down near the
karabiner.
