-- cloth
The upper and lower panels are made with 45 gr. Porcher Marine Skytex nylon. The ribs
are made with stronger (slighly heavier grade) nylon of to prevent aerofoil deformation,
even after several years of intensive use. Rib (cell wall) reinforcements are made of
Dacron 310-
180
gr. Line attachment points are made of polyester.
-- lines
The lines are made of Superaramid kevlar covered with a polyester sheath for protection
against wear, UV and abrasion. The riser karabiners, also called "Maillons Rapide", are
made with stainless steel of. Risers are made of pre-stretched polyester.
> certification
The ZENITH is a paraglider of a intermediate level that has passed the tests of the EN
evel B with great success. This glider has successfully passed the DHV shock test with a
weight equal to the maximum total (all up) take-off weight. This means that the
paraglider is certified to resist to a load of 8 (eight) times the gravitational acceleration
(8 G s).
As regards the weight range of the glider, ALWAYS be
certain that you are within the correct weight range of
the glider. To fly under-weight or over-weight can
adversely affect the stability of the ZENITH & flown as
such it will no longer be certified.

&
the speed system
Best glide in nil wind, and still air, is obtained at “trim”
speed- that is brakes fully released and no accelerator
(speed bar) applied. It is always best to fly with a light
pressure on the brakes, keeping a “feel” on the wing in
case of unexpected turbulence.
When flying into (against the) wind a better glide can
be obtained by using the speed system. The following is
rough guide line as to how much speed system to apply:
- With around 10 km/h of head wind, best glide is
obtained with 25% accelerator.
- With around 15-25 km/h of head wind, best glide is
obtained with 50
%
accelerator.
