Congratulations!
Thank you for choosing the DAVINCI GLIDERS HULA.
The HULA has been designed for mountain and Hike and y for the
paraglider.
The HULA is EN-A glider, it is also a progressive and innovative para-
glider avaible of full range of pilot from beginer to advanced pilot.
This manual will help you to get all information about your glider.
We strongly recommend that you read this manual carefully in or-
der to be aware of any general limitations, performance character-
istics, take- o and ight characteristics, landing procedures, deal-
ing with emergency situations, and general maintenance.
This is information about the design of the HULA, advice on how
to use it best and how to care for it to ensure it has a long life, We
hope that the HULA will give you a lot of satisfactory ying times.
WARNING!
THIS IS NOT A TRAINING MANUAL. ATTEMPTING TO FLY THIS OR
ANY OTHER PARAGLIDER WITHOUT PROPER INSTRUCTION FROM
A CERTIFIED PROFESSIONAL INSTRUCTOR IS EXTREMELY DANGER-
OUS TO YOURSELF AND BYSTANDERS.
DAVINCI GLIDERS are carefully manufactured and inspect-
ed at the factory. Please use the glider only as described in
this manual.
Do not make any modications to the glider.
As with any sport – without taking the necessary safety pre-
cautions, paragliding can be dangerous.

3. Introduction and Pilot Target
The HULA is an ultralight glider and suitable for a full range of pilots from beginner and advanced pilots.
The HULA is a Hike and Fly wing. Light and compact take-o complete the hike in any terrain and situation, and
the smooth handling and thermaling make for a pleasant mountain ight.The application of SN+ provides a longer
stall point and a sense of stability even in rough ight conditions. With the application of SBS, you can have more
relaxed during take-o than during the ight.
Whether you’re a hiking fan, and a student pilot looking for light wings, the HULA will provide you with the
satisfaction and happiness of the critical moments of your adventure.
-LTF and EN certication
The HULA is certied during ocial testing as LTF /EN-A.
The glider has been type-tested for“one-seated” use only.
-For the HULA has a maximum of 65cm symmetrical travel length at maximum total-load.
It would be dangerous to use the brake travel according to those numbers, because it is not practicable to measure
the brake travel during ight, and in turbulence, the stall might occur with less brake travel. If you want to use the
whole brake travel of your glider safely, it is necessary to do many intended spins and full stalls to get a feeling for
the stall behavior.
-Smart Nose Plus gives you a more relaxed response time in important moments
-Smart Ballance System oers a more automatic safe posture during take-o and ight
-Combination of Lighter and durable fabric
-Easy ination and smoother take-o
-6 sizes covering 50 to 120KG in 2 colors
-Basically oered with 12mm Kevlar riser, Dyneema riser can be chosen for lighter weight
The HULA is certied for harnesses in Group GH(without rigid cross-bracing). The suspension points of
the chosen harness should ideally have a carabiner distance of approximately 45cm and a height of 40 to
48cm.

7. Accelerator system
They come in dierent diameters of Kevlar and Dyneema with sheathed cover. They must be inspected
every 100 hours or 12months maximum.
In the case of Brake lines, it was cut a little longer, so every pilot can adjust it according to his personal taste.
But you must always leave 10cm before the brakes line starts acting in order to avoid trailing edge
deformation when the wing is fully accelerated. In case the brake handle comes loose during ight or any
brake lines are cut you can use the C riser softly for directional control instead of the brake line.
The accelerator has been limited in travel up to a safety point, however, you can gain 8-12 km of extra speed.
The speed system length is 12cm (S to L) and 10cm (XXS and XS).
You have to adjust the harness to the speed system so you can use all the speed travel.
To do so you have to be seated in the ground meanwhile you are in your harness and adjust the lines by
pulling up the risers with tension. Another person’s helps to do this is recommended. Make sure also that
the speed bar is not pulling down the risers when you are not using it.
Once all the gear is rigged you have to test the whole speed travel in calm air. The use of the speed system
reduces the angle of attack and the canopy may be more sensitive to collapses therefore do not use near
the ground or in turbulent air and in case you are hit by turbulence remove your feet o the speed bar as
quickly as possible. Always far away from the ground when using the speed bar.
5. Risers
HULA has 3 risers. The A riser has a red cover to easy identi-
cation. There is another line with red mailon. There is A’ and
is for the big ears.

8. Pre-ight check
9. Take-0
To know yourself with the glider it is a good idea to perform practice inations and ground handling in
advance.You should have no diculties ying the HULA for the rst time in suitable conditions, but as with
all new equipment.
When you have the new glider, the below points should be inspected.
- Check the lines are clear and not twisted.
- Connection points between the glider and harness.
- All harness buckles are closed.
- The Karabianers are fully closed and not damaged.
- The sewing, condition of the lines, and connection of the lines are right
- Internal damage to ribs and diagonal ribs.
- Demage to the top and bottom panels and seams between panels
HULA has easy ination behavior at the forward/reverse launch because of its prole system.
To get the right-wing shape for the take-o, pull the brake until the canopy shows the perfect
banana shape on the at ground. While inating the HULA, you should hold both of the A risers
in your hands. Smoothly and gradually inate the wing. It does not need excessive energy and
you feel the lift force very fast. It does not tend to over-shooting characteristics and provides a
9.1 Tow launch
The HULA is easy to launch using a winch and it has no special skills. To practice this
launching technique special training is needed and you have to know the procedures
and dangers, which are specic to winching. We do not recommend using any special
towing device which accelerates the glider during the winch launch.

11.2 Frontal collapse
HULA does not come out asymmetrical front collapse by itself. It has high internal
pressure with its well-designed prole. However asymmetric collapse may occur in
strong turbulent conditions, but It could be fast recovered if you apply the brake down
to 15 to 20cm. Release the brake lines, you may recover to the normal ight.
10. In ight characteristics
11. Deations
11.1 Asymmetric collapse
The asymmetric collapse usually happens when the pilot has not foreseen this possible
reaction of the wing.
Asymmetric collapses should be controlled by weight shifting away from
the collapse and applying enough brake to control your direction. And you
should use the brake to re-inate the glider.
HULA has the best stable glide performance in a normal position with no any brakes. In strong thermals and
turbulence, we recommend gently pull both brakes without acceleration to increase stability. The brakes
provide feedback about the surrounding air, which is needed for active ying.
To familiarize yourself with the HULA your rst turns should be gradual and progressive. To make ecient
and coordinated turns with the HULA rst look in the direction you want to go and check that the airspace
is clear. Your rst input for directional change should be weight-shift, followed by the smooth application of
the brake until the desired bank angle is achieved. To regulate the speed and radius of the turn, coordinate
your weight shift and use the outer brake.
In the unlikely event that a brake line releases from the brake handle or breaks, the glider is maneuverable
using the C-risers. By pulling gently on the C-risers it is possible to steer the glider and land safely.
Alternative Steering:
In the unlikely event, that a brake line releases from the brake handle, or breaks, or the brake-lines are
tangled up, the glider is maneuverable using the rear-risers. By pulling gently on the rear-risers, it is possible
to steer the glider and land safely. Don’t pull the rear-risers too much, to avoid a deep stall!
In spite of the HULA has great stability of the ight, strong turbulence or piloting error may cause a portion
of the wing suddenly to be deation.

DAVINCI GLIDERS / HULA

11.5 Asymmetrical stall
11.6 B stall
It can take place when you pull one of the brakes too hard, or while spiraling at a small
speed in turbulence you increase the angle of attack. Rotation in the asymmetrical stall
is called a negative spiral. This is one of the most dangerous ying situations. In order
to get out of the asymmetrical stall, just release the brakes. There may follow side thrust
forward with the following wing collapse.
The HULA has a very clean stable B stall. To enter the B stall, the pilot has to pull the rst
20cm slowly until the glider loses forward speed and starts to descend at around 6 m/s
vertically. Do not release the brake handles during B stall. If you pull too much B-line
the glider may horseshoe and move around a lot. If this happens, release the B risers.
To exit the B-stall the B-risers should be released symmetrically and in one smooth,
progressive motion. The glider will resume normal forward ight without further input.
Check you have a forward ight again before using the brakes.
11.4 Deep stall
11.3 Full stall
It is possible for gliders to enter a state of the deep stall. This can be caused by several
situations including; a very slow release from a B-line stall; ying the glider when wet; a
very old glider; or after a front/symmetric deation.
When you meet this situation you should fully raise up both brakes and push the
A-risers forwards or use the speed bar symmetrically to regain normal ight.
The full stall can occur when you fully pull both brakes enough a long time. This means
that the wing loses its forward momentum. To recover to the normal ight you must
release both brakes. After this usually comes a front dive with a possible front deation.
An asymmetric recovery (one control released faster than the other) from a full-stall can
cause a big dynamic collapse.The full-stall is a hazardous maneuver and as such outside
the scope of this manual. You should practice and learn this maneuver only on an SIV
course under a professional instructor.

DAVINCI GLIDERS / HULA

12.2 Spiral dive
The spiral dive is the most demanding descent technique and should be
learned at enough height, preferably during an SIV course.
When you hold one- sided brake down for a long time, the glider goes into a fast sharp
turn and loses a lot of height. The sink rate could be more than 15 m/sec. To get out of
the spiral dive you must release the inner brake and use the outside brake to manage
your sink rate. Mind that HULA may take one more turn after releasing the brake.
12. Descent Techniques
12.1 Big ears
The sink rate can be decreased in a controlled way by folding both wingtips. While
holding the brakes you should symmetrically pull the outermost A-risers.
In order to return to the normal ight, you should release the A-risers and
pull the brake short times until wing tips regain pressure.
Spiraling is not permitted with big ears, because of the increased load on the
remaining lines so that they can be physically deformed.
11.7 Cravat
In case a cravat should occur from an asymmetric collapse or other maneuvers, it is
important to keep your ying direction by applying some brake on the opposite side
and weight shift.
You can also use strong deep pumps on the brake to the cravated side. If a pull of the
brake line is unsuccessful, pulling the stable line which is the outermost line on the
B-riser may work.
If you can not do it and the rotation is increasing, you must use the parachute.

14. Packing your HULA
15. Maintenance and cleaning
Spread the HULA completely out on the ground. Separate the lines to each side. The HULA must be folded
cell to cell to keep the plastic reinforcement at the leading edge lie at on each other and don’t get bent. Try
to pack your HULA as loosely as the rucksack allows because every fold weakens the fabric.
Avoid packing the glider where it is wet or abrasive conditions(sand, asphalt pavement, concrete)
Cleaning should be carried out with only pure water. If the glider comes in contact with salt
water, clean thoroughly with fresh water. Do not use solvents of any kind, as this may remove
the protective coatings and destroy the fabric.
13. Landing
We recommend landing with trimmers to the normal slow position. Don’t use sharp turns or radical
maneuvers.
When you are 1-2m over the ground, you should face into the wind and standing upright and ready to run.
Finally, you may pull the brakes smoothly for minimizing vertical speed.
Don’t hit the ground by your overtake the glider. If you in windy condition, as soon as you touch the ground
you have to turn around to face the glider and move towards it during full pulling break symmetrically.

17. Warrantee
18. Respecting nature and environment
The producer guarantees the correctness of the declared characteristics and the paraglider’s
normal performance for two years after the purchase date. The producer conducts special, and
after warranty repairs and maintenance at the owners’request for an extra price.
We recommend inspecting your paraglider (including checking suspension line strength, line
geometry, riser geometry, and permeability of the canopy material) one time , or every 100
hours of ying time (whichever comes rst); that inspection must be made by the manufacturer,
importer, distributor, dealer or other authorized persons.
The checking must be proven by a stamp on the certication sticker on the glider as well in the
manual book.
There are not necessary spare items except the rubber ring to x the main lines on the riser
triangle carabiner. The rubber rings will be oered by us in the repair kit oering with the glider.
You can exchange it by yourself when it has been disappeared or wears o. After you exchange
the lubber ring, you must check again the triangle carabiner on the riser has been locked well
before you y.
Finally, we would ask each pilot to take care of nature and our environment. Respect nature and
the environment at all times but most particularly at take-o and landing places. Respect others
and paraglider in harmony with nature.
Do not leave marked tracks and do not leave rubbish behind. Do not make unnecessary noise
and respect sensitive biological areas.
The materials used on a paraglider should be recycled. Please send old Davinci gliders back to
us Davinci Gliders oces. We will undertake to recycle the glider.
16. Caring tips
- Do not expose your glider to the sun any longer than necessary
- Keep it away from water and other liquids
- Do not let the front edge hit the ground
- Keep your glider away from re
- Do not put anything heavy on your glider, do not pack it in a rucksack too tightly.
- Regularly inspect the canopy, lines, risers and harness. If you nd any defects,
contact your dealer or the manufacturer. Do not attempt to repair the paraglider by yourselves.
- If you detect a damaged line, inform the dealer or manufacturer about the line number
according to the line plan
- Keep your HULA in a bag in a dry well-ventilated place under neutral temperature and
humidity conditions
- If you do not use the glider, then once a month you should unpack it, ventilate it well,
and then pack it back in the bag
