At UP we are always testing new materials
to see if our wings can benefit from new
developments in the textile industry. After
comprehensive tests we have settled on
the following Porcher Marine material mix
for the Trango XC³
Top sail front + design stripes:
9017 E25 "Skytex 38 Universal"
(38 g/m²)
Top sail rear/ Bottom sail: 70000
E71
„Skytex 27“ (27 g/m²)
Ribs and V-Tapes: 9017 E29A
(40 g/m²)
This mix comprises the best compromise
between weight/bulk and longevity.
Line material
The lines used on the UP Trango XC³ are
unsheathed Dyneema® and Aramid lines
made by Edelrid, Cousin and Liros.
Diameters from 0,5 mm to 1,5 mm are
employed (brake lines sheeted).
A new manufacturing process in which the
lines are pre-stretched makes these lines
particularly stretch- resistant, and they
have little or no tendency to shrink. Their
break-load is noticeably 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
B-Level: BI,BII, BIII, STI
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 D-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 (A, B, C and D) are
colour coded for easy identification
and handling. 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.
Risers
The split A risers and B risers are
colour marked to improve ground
handling and B-lining/Big Ears.
A Risers: Red
A3 Risers (for Big Ears): Green
B Risers: Blue
C Risers: Black
In order to accommodate different pilot
sizes the Trango XC³ risers are lenght-
adapted to the canopy size
– S and
SM has shorter risers than M and L.
