Congratulations on the purchase of your new paraglider
The QUARX 2 is a very versatile wing and has been designed for all types of recreational flying, from long cross country and competition flying, to relaxing smooth evening and
morning soaring flights.
We strongly recommend that before you even unfold the QUARX 2 you read this
manual carefully in order to be aware of any general limitations, performance characteristics, take off and flight characteristics, landing procedures, dealing with emergency
situations and general maintenance.
We appreciate your feedback, so please send us your comments, positive or negative, in
regard to the
Windtech
range.
You are the best feedback and support for future products, and please remember that we
are always happy to give you any help & advice.

> warning & liability
This manual has been created to give the pilot help and hints to help with the correct operation of this wing. By no means is this a substitute of a training course, or appropriate
experience gained with years and hours of airtime, nor is this manual intended to give
pilot´s knowledge regarding flight safety.
Windtech
assumes that the purchasing pilot has the appropriate pilot's licence, has
taken a training course, and has the suitable ability and enough experience to safely fly
the QUARX 2.
This manual cannot be used for operational purposes. The flight log & registration card
must be filled and stamped by the dealer & returned to
Windtech
in order to claim on
the guarantee.
The use of this paraglider is entirely at the user's own risk. As with any adventure sport
paragliding is a high risk activity-especially without taking the appropriate precautions therefore it must be absolutely understood that
Windtech
& the dealer do not accept
any responsibility for accidents, losses, injuries, direct or indirect damage following the
use or misuse of this product.
> desing materials
The QUARX 2 is a DHV 2 glider
that offers total security, along with
beautiful handling & incredible performance. The performance is very
high due to a well-defined structure
with 67 cells, with an internal structure comprised of diagonals of different types, depending on the width
of the cell and an optimized line
layout to reduce the overall number
of lines.
-cloth
The upper and lower panels are made with 44 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
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 lower section of the brake lines is made from
Dyneema. This material is less prone to failure after repeated use through the brake
7
pulleys. The riser karabiners, also called "Maillons Rapide", are made with stainless steel
of 800 Dan. Risers are made of pre-stretched polyester of 900 Dan.
> certification
The QUARX 2 is a paraglider of a intermediate level that has passed the tests of the
DHV level 2 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 QUARX 2 & flown as such it will no longer be a certified glider.
> best glide & 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 applied.
-With around 15-25 km/h of head wind, best
glide is obtained with 50% accelerator applied.
-With around +25 km/h of head wind, best
glide is obtained with 75-100% accelerator
applied.
When flying downwind (wind from behind ) the
best glide is obtained between 0% brake and
10% of brake.
The QUARX 2 is a DHV
2 accelerated but
using the accelerator system close to the
ground is not advisable & it should be released
as soon as turbulent air is encountered.
Note that the glide angle is not affected by the
wing loading, but that the security is.
Always fly a glider that is the correct size for
8
you, and remember that if your flying weight is below the stated minimum, the speed
range will diminish and inflation problems may appear. Also the handling will degrade in
turbulent conditions, and it will be easier to sustain collapses. If your flying weight is
above the stipulated weight range, this will result in a higher minimum speed and faster
landing speed and the stall speed of the glider will also be higher.
The QUARX 2 has a brake of medium weight resistance (from 1.5 to 3 kg of force) for
the majority of manoeuvres. To reach the stall (never recommended on any type of paraglider), requires more than 9kg.
> flight
Each and every glider has a checklist note passed though our strict quality control in the
factory. This included line measurement, ground inflation and flight testing. Contact your
distributor for more information about this, and if your glider has not been pre-inflated
ask him to do so for you. Every glider should be test flow before it is sold.
Note that each glider has a unique sticker attached to the centre airfoil with the serial
number, type of glider, size and weight range.
We recommend that your first flight on your new glider be on a gentle slope in calm con-
ditions before making your any
further higher flights, just to
check the glider and for you to
get used to flying it. We also
recommended that you use a
harness that has an ABS cross
strap system and the maximum
width possible for the chest strap
is 38 cm between karabiners.
For you own safety, we strongly
recommend the use of back protection, helmet and Wind-SOS
reserve.
>launch
Choose an open space free of any
obstacles, especially trees and
power lines.
Open your glider in a slight horseshoe arc (semi-circle) & thoroughly check that you have
no knots or line twists. Make sure your helmet is securely fastened & clip into your harness making sure all straps are securely fastened.
Connect risers to your harness making certain that your karabiners are fully closed & you
