3. Introduction and Pilot Target
The RHYTHM2 is an easy-going EN/LTF A glider that is suitable for the training of paragliding. The main
focus of the design is on safety and maximum forgiveness in handling, but with an eye to handling and
performance. The RHYTHM2 is perfectly suited for beginner pilots looking for a glider with maximum safety.
Long brake travel and excellent passive safety, as well as good stability, make the good ideal for progression.
The RHYTHM2 sits well within the limits of the LTF/EN-A class as proven by the certication test results in
all maneuvers.
-LTF and EN certication
The RHYTHM2 is certied during ocial testing as LTF /EN-A.
The glider has been type-tested for“one-seated” use only.
-Suitability for training The RHYTHM2 is suitable for use in school and educational ying.
-For the RHYTHM2 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.
4. Harness
The RHYTHM2 is certied 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 dierent diameters of Kevlar and Dyneema with sheathed cover. They must be inspected
every 150 hours or 24months 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
RHYTHM2 has 3 risers. The A riser has a red cover
to easy identication. 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 inations and ground handling in
advance. You should have no diculties ying the RHYTHM2 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
RHYTHM2 has easy ination behavior at the forward/reverse launch because of its prole 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 inating the RHYTHM2, you should hold both of the A
risers in your hands. Smoothly and gradually inate 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
9.1 Tow launch
The RHYTHM2 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 specic to winching. We do not recommend using any special
towing device which accelerates the glider during the winch launch.

11.2 Frontal collapse
RHYTHM2 does not come out asymmetrical front collapse by itself. It has high internal
pressure with its well-designed prole. 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. Deations
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-inate the glider.
RHYTHM2 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 RHYTHM2 your rst turns should be gradual and progressive.
To make ecient and coordinated turns with the RHYTHM2 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 RHYTHM2 has great stability of the ight, strong turbulence or piloting error may cause a
portion of the wing suddenly to be deation.

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 RHYTHM2 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 deation.
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 deation.
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.
