Aerofoil Stabilising System²
UP was first with the Aerofoil Stabilising
System, an idea that has since been
widely accepted in the industry. The
Makalu Light uses a modified version of
the same, and we have chosen to call this
the ASS². Instead of Mylar® the ASS²
comprises a Nylon® batten that defines
the leading edge curvature and helps
keeping the cell opening open at all times.
This Nylon® batten is insusceptible to
bending damage and has no ageing
properties
– it will normally outlast the rest
of the canopy by a good margin. This
means that the UP Makalu Light will retain
its perfect launching characteristics all
through its service life. In the unlikely
event that a batten should break it can be
replaced in a few easy steps
– please
refer to the chapter “Replacing ASS
battens” for guidelines.
Performance data
Main focus area during the development
phase of the Makalu Light was to make a
wing that would suit both weight watchers
and “normal” paraglider pilots with an
interest in lightweight material. With
the Makalu 3 we already had what we
felt was the perfect wing for the
category, only some pilots like their kit
lighter still. The Makalu Light is
essentially a Makalu 3 at heart, but
insofar as sizes can be compared it is
roughly
1.1kg
lighter
than
the
provenance, and significantly more
compact
when
packed.
The
performance of the Light is at least as
good as the Makalu 3, but the thinner
lines and lighter canopy have made a
wing that is slightly more dynamic to
fly. Since most pilots will likely fly the
wing heavier than they would a Makalu
3, this contributes further still to the
dynamics in flight.
Canopy material
The UP Makalu Light is sewn from
polyamide cloth, which is particularly
stretch-resistant and durable, and is
specially treated for maximum UV-
resistance.
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/Dominico
Textile
material mix for the Makalu Light:
Leading edge top: 70032 E3X
"Evolution Plus" (32 g/m²)
Trailing edge top: 70000 E71
(26 g/m²)
Bottom sail: 70000 E71 (26
g/m²)
Ribs and V-Tapes: 70032
E4D (32 g/m²)
This
mix
comprises
the
best
compromise between weight/bulk and
longevity.
