The MAC
YUKON |

The
Yukon is an ultra light paraglider for
pilots and mountaineers. The Yukon has
excellent handling with light brake pressure
and the glide ratio is just wonderful. Easy
to transport the Yukon combines the powerful
features of a performance-intermediate
glider with a low weight.
The Yukon features specially developed
airfoils to provide extraordinary glide
ratio and stability. This bias toward safety
becomes evident from the technical
specifications, with 46 cells and an aspect
ratio of 5.12, the design clearly leans
toward that of the typical intermediate. The
smooth shape of the airfoil nose is
maintained by thin nylon rods to achieve low
weight. The Yukon has very easy ground
handling. Everything feels very predictable
in all launch conditions. The ease with
which the canopy can be brought over pilot’s
head is just excellent. The wing flies
intuitively and unaided from the beginning.
Intensive testing resulted in a well
balanced glider with very simple take-of
characteristics and easy behaviour during
extreme manoeuvres. The canopy of the Yukon
is moderately damped in all axes but the
canopy responds to commands quickly and
willingly accepts all inputs. It offers
lively and sporty handling. Thermaling is a
real joy. Powerful and well damped, the wing
can be easily turned with wonderful climbing
performance. The Yukon neither dives,
sits-back, nor has any tendency to be
ejected from the thermal. The brake pressure
is light , giving comfortable feedback. It
allows pleasant turns during long thermal
fights and increases progressively towards
the end to offer a good safety margin. It is
hard to achieve a stall from normal inputs.
Provoked collapses of the leading edge (even
when accelerated) reopen laterally with a
maximum turn of 90°. It features excellent
stability in accelerated flight. The speed
system operates easy and the glider reaches
a respectable maximum speed of 50 km/h.
The
line concept is simple with four rows, each
with 3 main lines. The top lines are thin
durable unsheathed Cousin Vectran lines.
Bottom lines are sheathed Edelrid Kevlar
lines. The Yukon is equipped with thin lines
and with light Dynema risers. The Dynema
tapes are protected by a sheath. As standard
the lines are connected to the risers by
loops to save weight. Also available are
risers with small triangular maillons for
pilots who prefer the system commonly used
for paragliders.
The
Yukon features excellent stability
throughout the full weight and speed range.
The Yukon is a great lightweight glider.
The use of high-quality materials and
constant quality control during
manufacturing process together with
consistent development work on our computer
programme “PG” produces high quality
products. We are proud of them. |

The Yukon is
manufactured using the paragliding
industries well established lightweight
materials . Because for any glider, the part
that always wears out first is the leading
edge, we use Skytex 36 with coating E 68A
for this. For the less stressed areas of the
sail we use Skytex 27 with E 71A coating
for top and bottom sail. For the supporting
and diagonal ribs we use Skytex 32 with
“hard finish” coating E29A. This gives the
advantage of a sail that is both lightweight
and very durable
