2 POSSIBLE USE_
2.1 Motorised Paragliding
The Xrocket is ideally equipped for the motorised flight due to its outstanding rise features,
its uncomplicated handling and the high trimmed speed. Please note that no acro-
manoeuvres are allowed in motorised flight. Due to the higher wing and surface loading in the
extended engine weight range, the according reactions are responding more dynamically.
Opening the trimmer reduces the angle of attack and also causes a higher speed and thus
more dynamic behaviour. It is recommended to keep the trimmers closed when flying through
turbulent air. In order to keep the take-off distance and take-off speed low, the trimmers
remain closed during take-off, especially when there is little wind.
The extremely high area loading through the additional weight of the motor brings even the
GRAVITY Xrocket to its load limits. Pay attention to the extended engine weight range which
changes/ alters the take-off and landing speed considerably. Currently GRAVITY Xrocket is
certified for motorised usage, the allowed weight ranges must not be exceeded!
2.2 E-climbing assistance/ E-ascent aid
Due to its unproblematic handling and high trim speed, the GRAVITY Xrocket is ideally suited
for the e-ascent aid.
2.3 To wi n g w i n c h e s
The GRAVITY Xrocket offers excellent starting characteristics with its high trim speed, best
conditions for towing winches. The following must be observed when towing winches/
aerotow:
– The GRAVITY Xrocket must not be towed over 100 kp
– Unless towing on your “house winch”, it is absolutely necessary to familiarize yourself
with the local conditions in advance. Every “guest” in a foreign/ new flight area must
be instructed by the local pilots.
– Never tow the GRAVITY Xrocket with a load exceeding the approved weight limits
– All persons and facilities involved in winch operation must have the required
qualifications or approvals for towing paragliders on the winch. This applies to the
pilot, winch operator, towing device, towing pawl and all other devices for which a
certificate of competence is required

USER MANUAL
GRAVITY Xrocket
EN REV.V01 - 2020
3 THE DEFAULT SETTINGS_
The delivered brake line and default setting corresponds to the setting 0-leeway plus 5 cm.
It is recommended to adjust the brake handle to your personal needs after the first flight.
Remember that the brakes should not be set too short, otherwise the glider would fly
continuously braked. These situations would be extremely dangerous for take-off, flight and
landing!
The default setting is in extreme flight situations and when landing
sufficient braking distance available. At the same time, it enables a comfortable arm position
for the trim flight. Under no circumstances should the basic setting of the A, B and C lines be
changed.
PAY ATTENTION_
Please note that the relative braking distance changes with the height/ length of the harness.
When fixing the setting, make sure that both sides are symmetrical and that a permanent knot
is used. The double fisherman’s knot/ spar or pile stitch has proven particularly effective in
that since it weakens the lines the least with excellent slip resistance.

4 SECURITY PRECAUTIONS_
1. 1. Before the first flight, the cap, lines, all connections and sewing, the shackles, brake
lines and brake line knots as well as any twisted lines must be checked by appropriately
trained personnel and confirmed on the type plate
2. Make your first flight in a known flight area/ territory and in calm conditions
3. Test your GRAVITY Xrocket only over water
4. During a "dynamic flight" the gravitation does not only affect you, but also on the
glider. Do not underestimate this state and the forces!
5. Always fly your GRAVITY Xrocket with at least one rescue device!
6. Compliance with the air traffic act and regulations are applicable in the respective
country must be observed and revised carefully
7. Successful, certified completion of the appropriate training and license as well as the
current existence of the appropriate level of knowledge / the current flight experience
are prerequisites for using the GRAVITY Xrocket
8. The use of suitable, tested and approved accessories (helmet, harness, rescue device)
is a prerequisite for using the GRAVITY Xrocket
9. Carry out a thorough material check of your equipment (top sail, bottom sail, ribs,
especially the lines, carabiners, belt buckles, cloth, speed system, etc.) before every
start
10. A flight with a crack or hole in the wing or line can be life-threatening
11. Always make sure that the aircraft is in a proper flying condition and that the required
inspections have been carried out regularly
12. Be aware that as a pilot you must be physically and mentally able to carry out the
flight unimpeded. You have to concentrate fully on flying in order to possibly avoid
unpleasant flight conditions
13. Most accidents are due to pilot errors
14. Never fly near high-voltage lines, airports or highways, over people or during a
thunderstorm! Otherwise you could endanger the life and physical integrity of third
parties and / or your own and act grossly negligent at the same time!
15. The minimum distance must never be less than 50 m. At airports, this is a radius of 5
km
16. Find out about the prevailing weather conditions in the weather report and on site in
advance
17. Only use the GRAVITY Xrocket at wind speeds where you are able to control the glider
100%
18. Never use the screen during approaching thunderstorms or storms or when there is a
high probability of thunderstorms or storms
19. Land immediately when thunderstorms or bad weathers approach!
20. Aerobatic flying is generally prohibited and life-threatening. Unpredictable flight
situations can occur that may get out of control. There is a risk of physical and thermal
overload on the material and/ or the pilot
PAY ATTENTION_
Failure to disregard one or more safety precautions or violation can
turn flight fun into a life-threatening event.

5.6 Speed/ acceleration system
The GRAVITY Xrocket is equipped with a very effective foot extended acceleration speed
system. It increases the speed when applied up to approx. 15 km/h depending on the wing
size and pilot weight resp. surface loading. Through the level steered speed system, the profile
form is maintained there- fore the outstanding flight features are kept even in high speed.
all extreme flight attitudes (e.g. collapses) happen at accelerated speed more dynamically.
The speed system needs to be adjusted before the first flight. Therefore, the connection lines
of the foot extensor are being connected through the Brummel hooks with the speed system
on the riser. To be able to undertake the right adjustment the harness should be hung up so
you can sit in flying position. The attached risers are best held up by someone else. It should
be adjusted in a way so that the pulleys are on top of each other and you have your legs
stretched out. and you are also responsible to watch out that the speed system is adjusted
symmetrically and not too short so the glider is not pre-accelerated in the flight.
The two-stage speed system also enables an exact fine adjusting at your harness (foot
accelerator). By moving the knot that fixes the ball the accelerator distance and pressure can
be individually adjusted.
1. If the knot is moved down towards the harness suspension, the second stage is
reached sooner thereby the accelerator way is shortened.
2. If the knot is moved up towards the line shackles, the second stage is reached later
and the accelerator way is getting longer.
NOTE_
Take care that the accelerator is not adjusted too short so the glider is not pre-
accelerated before the flight
5.7 TRANSPORTATION and STORAGE_
When transporting the paraglider, make sure that it is not exposed to any kind of liquid. It
must be packed dry. When storing the Xrocket, it should be ensured that it is not exposed to
UV rays. In addition, it must not be stored together with acids or the like or anywhere near
them. Dry storage is extremely important.
PAY ATTENTION_
After a long storage period, the glider must be checked thoroughly.

6 THE FLIGHT_
6.1 Flying experience
These operating instructions only deal with the relevant points regarding flight technology
that are important for the GRAVITY Xrocket. It cannot and should not replace sound flight
training in a recognized, authorised flight school! Without flight training and experience, flying
with paragliders is extremely dangerous!
6.2 Ta k e -off
After the paraglider has been unpacked and laid out in a semicircle, the following points must
be followed and checked:
1.) the paraglider should be flattened out in a way that the lines in the middle of the paraglider
are evenly under tension and slightly earlier than those at the wing ends when they are
pulled up with the A-risers. This ensures an easy and directionally stable start
2.) When laying/ flattening out, please pay attention to the wind direction so that when
pulling up against the wind both halves of the paraglider can rise symmetrically
3.) If the risers are not twisted, the brake lines run freely through the guides to the rear edge
of the glider
4.) No lines are to run directly underneath the canopy cap. Make sure they are properly
organized underneath the gilder canopy. Otherwise it can have disastrous consequences
5.) The 5-point check should never be forgotten of course
The 5-point check should include the following:
a) buckled up/ strapped (helmet, harness and carabiners closed)
b) suspended (the risers are not twisted when hung in the carabiner, the accelerator is
correctly hooked in, the carabiner is locked)
c) lines (A-lines above, all lines sorted, brake line runs freely to the brake roll(er))
d) canopy (cap is arched with an opened leading edge at the start)
e) wind and airspace (wind suitable for take-off, free airspace)
The center of the screen of the GRAVITY Xrocket is identified by the GRAVITY logo on the
leading edge.
It is sufficient to only take the A main risers (into your hands). Since the GRAVITY Xrocket
only shows very little tendency to shoot forward/ exceeding the pilot, it only needs to be
slowed down a little in the starting phase. Any directional corrections with the brakes should
only be undertaken when the canopy is already over the pilot, otherwise the glider can fall
back due to excessive braking. The remaining risers should not be touched in the starting
phase.
The cap is filled with a steady, even pull and only a slight start impulse overall. Unlike
conventional gliders, it is not necessary to fill the GRAVITY Xrocket with strong wind-up
movements or even a few quick steps. This also applies to little wind and even zero wind,
Dosed winding is the easiest and safest way to start the GRAVITY Xrocket. Once the pilot has
made sure that the cap is fully open above him, the final decision to take off is made. After a
few dynamic steps, the pilot takes off.
