Congratulations on the purchase of your new CARGO.

The CARGO is a tandem wing that has been conceived and designed for both profes­sional and recreational pilots, suitable of all kinds of flying styles, from a gentle glide
down, to the most ambitious cross country flights. With easy launch characteristics,
manoeuvrability and turn ability akin to a solo glider, and superb performance, the
cargo makes it possible to core the smallest of thermals and climb even in the weak­est lift.

We strongly recommend that before you even unfold the CARGO you carefully read this
manual in order to be aware of any limitations, as well as differnces in performance, take­off and flight characteristics, landing procedures, emergency situations and maintenance.

We always appreciate your feedback, so please send us your comments, positive or neg­ative, regarding to the Windtech line.

You are the best feedback and support for future products, and please remember that we
are always happy to give you any help & advice.

Best winds

> warning & liability

This manual has been created to give the pilot help and hints for 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 pilots knowl­edge regarding flight safety.

Windtech assumes that the purchasing pilot has the appropriate pilot's licence, has

taken a training course, tandem insurance and has the ability and enough experience to
safely fly the CARGO.

This manual cannot be used for operational purposes. The flight log & registration card
must be filled and stamped by the dealer & returned 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 precautions­therefore it must be absolutely understood that
any responsibility for accidents, losses, injuries, direct or indirect damage following the
use or misuse of this product.

> philosophy of design

When Windtech decided to make a tandem paraglider, we first established the main cri­teria that we felt would be the most important to make the perfect tandem wing. The
wing had to be, above all, easy to inflate and launch in all conditions, with excellent han­dling, high glide performance, and that it would convert energy extremely well to give an
effective flare, for softer landings.

For this we designed a paraglider with 51 cells of variable widths, not all of which have
line attachment points due to the advanced structural relationship of lines/diagonals. In
this way we have considerably reduced parasitic drag produced by the lines whilst at the
same time endowing the interior of the wing with a higher internal pressure and creat-

ing calculated zones of greater longitudinal tension, very important for increasing resist­ance to tucks (above all frontal collapses).

The cargo’s new profile gives highly elevated security and performance, as well as a
turning ability that is surprisingly efficient.

It has double profiles in the leading edge, therefore it is safier, specially when trims open
and also has more performance at high speed.

The end result is a tandem that inflates quickly and easily during launch and is excep­tionally stable and solid during the take-off run, giving great protection against having
to abort launches and compromising the safety of yourself and your passenger.

During launch the cargo gives an exceptional degree of control, allowing the pilot to
easily make precise corrections during the take-off run. Once airborne, the cargo’s
superb feedback and responsive handling allows one to make the most of even the small­est thermals.

When the time comes to land, the exquisite handling characteristics and precision of the
cargo serve as another great guarantee of safety since you can first of all guide your­self more precisely into exactly the spot you wanted to land in, confident that in the final
moment, when you want to flare, you will be able to take advantage of the wings superb
energy conversion, landing both you and your passenger easy and safety each time.

> construction and
materials

Our primary concern is always keeping
to the highest quality standards of
materials and construction, to impress
the pilots and so guarantee our future.
For this reason, we never cut any cor­ners when it comes to building in qual­ity.

-- cloth

The upper and lower panels are made
with 45 gr. Porcher Marine Skytex
nylon. The ribs are made with stronger
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 of the highest quality and varying diameters, depending on which area of
the glider they are in, but always of a diameter greater than a solo glider, capable of with­standing a force up to eight times the maximum load. The inner core is super aramid and
the outer sheath polyester to protect against general wear and tear and UV.

> certification

The cargo is certified It is certified EN with A in all maneuvers but a B in the asym­metrical collapse maneuver.

> performance

Fly a cargo in the correct size for
you. Remember that if you fly outside
of the weight range that the glider
has been designed for, this could
adversely affect the handling, stabil­ity and performance of the glider,
and means that the glider is effec­tively no longer certified.

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 sustain collapses more easily.

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. If the glider suffers a collapse, or leaves normal flight configuration, the resulting
behaviour will be more rapid and violent. As well as this, your sink rate will be higher and
you will find it harder to stay up in light lift.

The cargo has medium brake resistance (adhering to weight range). The stall is found
at 95% of the brake travel and, to force the glider into an in flight full stall (not recom­mended on any kind of paraglider), requires almost all the weight of the pilot on the
brakes.

The best glide on the cargo, not taking into consideration any horizontal or vertical
movements of the air, is obtained simply by flying at the glider’s trim speed. That is to say,
by having the trimmers in standard position and flying with no brake or speed system
applied.

> flight

Before flying any paraglider, the pilot has to be sure that they are flying a glider that is
suitable for their level of piloting, evaluating objectively and carefully their true capabil­ities.

In the case of tandem flying, this is even more important, as one is carrying a passenger
and the price of any error will not only be paid for by the pilot.

Each and every glider has a meticulous checklist passed though our strict quality control
in the factory. This includes 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 them to do so for you. Every glider should be test flown before it is sold.

Note that each glider has a unique sticker attached to the centre cell with the serial num-
