> congratulations

Congratulations on the purchase of your new CORAL DHV 1.

The CORAL has been designed to offer maximum safety for the entry-level pilot, scho­ols & pilots that demand no compromise in stability. We strongly recommend that befo-

re you even unfold the CORAL you carefully read this manual in order to be aware of
any limitations, performances, take off and flight characteristics, landing procedures,
emergency situation and maintenance

We appreciate your feedback, so please send us your comments, positive or negative, in
regard to the

Windtech

range.

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

> warning & liability

This manual has been created to give the pilot help and hints to correctly operate this
wing. By no means is this a substitute of a training course, nor is this manual intended
to give pilot´s knowledge regarding flight safety.

Windtech

assumes that the purchasing pilot has a license and has taken a training

course in order to have enough experience to safely fly the CORAL.

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 CORAL is a DHV 1 glider that offers total security with beautiful handling & perfor­mance. The performance is very high due to a well-defined structure with 29 cells, with
different width and an optimal 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 nylon of to prevent airofoil deformation, even after several years
of intensive use. Rib (cell wall) reinforcements are made of Dacron 310 gr. Line attach­ment points are made of polyester.

7

--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
pulleys.

Karabiners of the risers, also called rapide maillons, are made with stainless steel of 800
Dan. Risers are made of pre-stretched polyester of 900 Dan

> certification

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 CORAL & will no longer be a certified glider.

> best glide

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 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 75­100% accelerator applied.

When flying downwind (wind from
behind ) the best glide is obtained
between 0% brake and 10% of brake.

The CORAL is a DHV 1 accelerated but using the accelerator system close to the ground
is not advisable & it should be released as soon as soon as turbulent air is encountered.

> 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 pre­inflated 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 con­ditions 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

Windtech

harness, spe­cially designed for this glider. It 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 have no
twists in the risers.

> strong wind

We do not recommend taking off, or flying, with a wind speed higher than 25 km/h; this
