1. Introduction About Gin Gliders Dream In forming Gin Gliders, designer and competition pilot Gin Seok Song had one simple dream: to make the best possible paragliding equipment that pilots all over the world would love to fly— whatever their ambitions. At Gin Gliders, we bring together consultant aerodynamists, world cup pilots, engineers and paragliding school instructors, all with one goal: creating better paragliders.
Manual We recommend that you familiarise yourself with your new paraglider by reading this Manual before your first flight. This will allow you to acquaint yourself its new functions, to learn the best way to fly the paraglider in various situations, and explain how to get the best out of your paraglider. Information in this Manual on design of the paraglider, technical data and illustrations are subject to change. We reserve the right to make changes without prior notification.
Gin Gliders and the environment Protection of the environment, safety and quality are the three basic values of Gin Gliders and these have implications on everything we do. We also believe that our customers share our environmental awareness. Respect for nature and the environment You can easily play a part in protection of the environment by practising our sport in such a way that there is no damage to nature and the areas in which we fly.
2. Safety WARNING The safety advices and instructions contained in this Manual must be followed in all circumstances. Failure to do so shall render invalid the certification and/or result in loss of insurance cover, and could lead to serious injuries or even death. Safety advice Paragliding demand a high level of individual responsibility. Prudence and risk-awareness are basic requirements for the safe practice of the sport, for the very reason that it is so easy to learn and practically anyone can do so.
Pilots are responsible for their own safety and must ensure that the airworthiness of the glider is checked prior to every flight. The pilot should launch only if the paraglider is airworthy. In addition, when flying outside of Germany, pilots must observe the relevant regulations in each country. The glider may only be used if the pilot has a licence which is valid for the area or is flying under the supervision of an approved flying instructor.
CCC certification The Boomerang 10 received CCC classification in the final classification by the licensing body. Description of flight characteristics „Paragliders with demanding flying characteristics and potentially violent reactions to turbulence and pilot errors. Recovery to normal flight requires precise pilot input.“ Target group and recommended flying experience „Performance pilots with extensive flying experience of at least approx.
Gin Gliders calculates and draws the plan of the glider with a distance between the carabiners of 44cm. CCC certification test flights are also carried out with this setting. We recommend setting a distance of 42cm to 50cm between the carabiners, depending on the size and design of the harness. Reclined harnesses Reclined harnesses are generally completely enclosed and often have a very low main attachment point. Active flying is very different with them than with an upright harness.
Overload The CCC describes the weight measurement with: “All weights are subject to an acceptable tolerance of ± 2kg”. Therefore a slight overload of the wing would be within CCC tolerances. However, flying over the maximum weight further increases the dynamic flight behaviour. High performance wings in particular start to lose their floating ability: in small bubbles, the wing has more horizontal momentum and less tendency towards lifting. A test flight is always recommended if in doubt.
3. Flying the Boomerang 10 The Boomerang 10 was developed for performance and competition pilots with extensive flying experience. The basic types of flying described below should be second nature for such pilots, but have been included in this Manual for the sake of completeness. Preparation for launch A careful pre-flight check is required for any type of aircraft. Make sure that you exercise the same level of care each time carry out the check.
Launch The key to a successful launch technique is to practice ground handling on flat ground whenever you can. The Boomerang 10 has good launch characteristics for its class, and no special launch techniques are required. Light or nil wind launch The Boomerang 10 inflates steadily in nil-wind conditions. Simply guide the glider by taking the A1 and A2 main lines just above the A1 riser, keeping your arms bent and hands at the level of the shoulders.
Accelerated flight Once you have become accustomed to flying the Boomerang 10, you can practice using the speed system, which allows improved glide in headwinds and greater penetration in strong winds. When flying accelerated the glider reacts much faster to a collapse. Also the glider reacts more radically when a collapse happens during accelerated flight compared to flying at trim speed. Apply the speed system by pushing the speed bar progressively with your feet.
If more brake is applied, the bank attitude increases and the glider will fly a fast turn increasing in steepness, which will eventually become a spiral dive (further information on this is in the section “Spiral Dive”). Losing altitude Extremely strong and widespread lift is found, for example, in storm conditions. The best place to be in this situation is on the ground. Nevertheless, if you have been caught out by the weather and find yourself needing to descend rapidly, there are several ways to do so.
weightshift actively to the outside of the turn and pull the outer brake until you feel the deceleration of the wing and your body moving towards a more upright position. Then, release the outer brake and let the glider decelerate for one or two more turns. Apply a short brake action on the inside brake just before the glider exits the spiral dive completely. This will burn off the remaining energy and avoid a big pendulum moment after exiting the spiral.
Tandem paragliding The Boomerang 10 has not been developed for use in tandem paragliding. Aerobatics The Boomerang 10 is not designed for aerobatics and in many countries acro flying is forbidden. Besides the inherent risks, extreme manoeuvres of any kind place unnecessary stress on the glider and effectively shorten its lifespan. We strongly recommend no acro flying or unnecessary manoeuvres to avoid a risk of unpredictable flight attitudes, which could lead to damage to material and structural failure.
4. Dangerous situations and extreme flying Dangerous situations Pilot error, extreme wind conditions or turbulence which goes unnoticed by the pilot for too long may leave the wing in an unusual flying position, requiring special reaction and skills on the part of the pilot. The best way to learn how to react calmly and correctly in a serious situation is to attend safety training, where you will learn how to manage extreme situations under the guidance of a professional.
Canopy collapses Collapses of the canopy can occur in strong turbulence. The Boomerang 10 will recover with pilot input through weightshift and B-riser control in almost all situations. Only if the wing surges very fast in front of you should you stop it with the brakes. However, it is recommended that you follow the advice below in order to help the wing recover more rapidly.
Fig. 1: Grabbing the stabilizer/winglet main line Alternatively, on the side of the wing with the cravat, pull the brake fast and strong. Be careful not to let the wing enter a developed spin. If the tangle has not come free after several attempts, you still have the option to open it like a deep stall or a full stall. These flight manoeuvres always require adequate altitude and a high level of pilot skill.
Deep stall (parachuting, stable stall) The Boomerang 10 has no tendency to get into in a deep stall. Should this nevertheless occur, make sure your brakes are fully released, the glider will then normally recover on its own immediately. If the glider still doesn’t recover either put your hands on the A risers and push forward or use the speed bar to accelerate the wing. You can recognise a deep stall by the glider getting "mushy" and the airflow around your ears decreasing.
Other tips for dangerous situations Cascade Many reserve deployments are a result of a cascade of over-corrections by the pilot. Please note that over-corrections are often worse than no input at all. Emergency steering If a brake is not operational for some reason, you can steer the Boomerang 10 with the B- risers. Add steering input by weight-shifting in your harness. Be careful not to pull the riser too much, to avoid any possibility of a spin.
Temperature range Temperatures under -10 °C and over +50°C can make the paraglider unfit to fly. The manufacturer’s warranty will lapse if the glider is used outside of this temperature range.
5. Storing, care, maintenance and repairs Storing the paraglider Packing the paraglider It is very important to pack the glider carefully in order to ensure the longevity of the leading edge reinforcements. Fold up the Boomerang 10 as shown in the diagrams below. The leading edge reinforcements (Mylar and Rigid-System) on the front edge are placed on top of each other to avoid bending or misshaping them.
6. 7. 8. Do up the zip, making sure that none of the lines or fabric is caught in the zip. Fold up the glider along its length, with the first fold below the leading edge reinforcements. Pay particular care not to bend any of the rigid reinforcements! Fold the glider again. Then place the compression strap around the glider and fasten it by pulling gently. Make sure that the glider is only loosely folded and is not bent or compressed excessively.
The Boomerang 10 should not be exposed to extreme heat (e.g. in the boot of the car during summer). The heat may cause any moisture present to be pressed through the fabric, thereby damaging the coating. High temperatures accelerate the process of hydrolysis, particularly when combined with moisture, which damages fibres and coating. Do not store your paraglider near radiators or other heat sources.
particularly when it is warm. This can make the paraglider unsuitable for flying within a short time. A brand-new glider will often be compressed when delivered. This is solely for the initial delivery and the glider should not be compressed in such a way again. Do not pack your glider too tightly after use and, even though it is very comfortable, never sit on the backpack with the glider inside.
to rinse the glider, e.g. following a landing in the sea, gently wash it down inside and out with fresh water. Frequent rinsing accelerates the aging process. Maintenance Type designation GIN gliders have an exact identification on the underside of the wingtip or on the centre rib, which is obligatory for all paragliders. The information required is set out in the airworthiness requirements.
Line trimming The Boomerang 10 is trimmed to give the highest possible level of performance and safety. The aramid lines may shrink or stretch in normal use and particularly after hard shock-reinflations. Pilots should check that the lines remain within tolerance. The Boomerang 10 is certified with the lines trimmed so that the total line length from tab to riser is within 2cm of the values stated in the line-plan.
WARNING Uncontrolled flight positions are outside the manufacturer limits of the paraglider. This may cause a general deterioration in flight characteristics, premature ageing, or even structural failure. Repairs Gin Gliders workshops All repairs and servicing should be carried out by a Gin Gliders authorised workshop or directly by Gin Gliders. Gin Gliders workshops have trained staff, original Gin Gliders parts and the necessary know-how, all of which will ensure top quality.

Riser and speed system Risers The 12mm wide risers specially developed for the Boomerang 10 with Kevlar reinforcement allow the pilot to use a pulley system to adjust the speed of the Boomerang 10 to suit individual preference. All technical data and measurements are provided in the CCC ‘Test-LabTemplate’. Fig. 6: Boomerang 10 riser Speed System The speed system increases the maximum speed by lowering the angle of attack with a pulleyguided, foot-operated system.
Line system, brakes and line plan Line system The Boomerang 10 has A and B line levels, which fork two or three times from the bottom (riser) to the top (canopy) and which are divided into "Main", "Lower-Middle", "Higher-Middle" und "Top" lines. The individual line levels are connected with one another using the “handshake knot” (special hoop technology). With the brake lines, the individual levels are bundled at the end with the main brake line.
Fig. 7: Bowline knot WARNING Loose, unsuitable or incorrectly tied brakeline knots can cause the main brake line to loosen and then lead to loss of control of the glider. Incorrect adjustment If the brake lines are too long, the paraglider reacts slowly and is difficult to land. The brake lines can be adjusted during flight by wrapping them around your hands which will improve the flight characteristics. Adjust the brake lines to the correct length after you have landed.
