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.
CIVL measurement file for CCC gliders (October 2014) Glider details Pilot details , proof of ownership and inspections and repairs overview This Manual was current at the time of going to print. This Manual can be downloaded from GIN’s website prior to print. Gin Gliders Homepage Gin Gliders has a comprehensive website, which provides additional information about the Boomerang 10, any updates to the Manual and many other issues related to paragliding.
Paragliding is, of course, an outdoor sport – protect and preserve our planet’s resources. Environmentally-friendly recycling Gin Gliders gives consideration to the entire life cycle of its paragliders, the last stage of which is recycling in an environmentally-friendly manner. The synthetic materials used in a paraglider must be disposed of properly.
Gin Gliders publishes on its website any technical safety notices and airworthiness instructions which are issued in respect of GIN products. The paraglider owner is responsible for carrying out the action required by the safety notice.
The complexity of the paraglider system means that it is not possible to give any more than a partial description of the glider’s flight behaviour and reactions to disturbances. Even a small alteration in individual parameters can result in flight behaviour which is markedly modified and different from the description given. 11 /48 Boomerang 10...
The Boomerang 10 is designed from the outset as a CCC competition glider, and has the highest performance of any GIN glider. It is suitable for the very experienced pilot who flies frequently...
Brake line adjustment Factory setting The brake lines of the Boomerang 10 are set to the length that was used for the CCC certification test flights. These line lengths have been finely tuned by the GIN test pilots, and it should not be necessary to adjust them.
If in doubt about this procedure, consult your instructor or dealer. Certified Harnesses The Boomerang 10 is certified for use with all harnesses with variable cross-bracing (GH type), such as the Gin Genie Race 3. Practically all modern harnesses are GH type harnesses. Older harnesses with fixed cross- bracing (GX type) are not certified and should not be used.
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.
4. 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.
Level flight and best glide When the brakes are open, the Boomerang 10’s flight is stable and level. The brake lines can be used to adjust the speed according to the flight situation, to ensure the optimum level of performance and safety.
Boomerang 10 pilot a very satisfying feeling of being connected to the air movements. A pilot fully in tune with the Boomerang 10 can use these B-riser inputs to follow the lifty lines that lead to the cores of thermals.
Big ears It is possible to do big ears on the Boomerang 10, but it takes great arm strength to hold in the ears and the glider loses structure when the ears are in. Therefore the maneuver is not recommended.
The minimum flying speed and big flaring reserve of the Boomerang 10 will help you to make a soft landing in all conditions. Approach the landing with sufficient airspeed and don't leave your last turn too late or too steep.
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.
The Boomerang 10 is under no circumstances suitable for a pilot’s first experience with safety training. Special folding lines were used for certification of the Boomerang 10 (refer here also to the section “Folding lines”). Without these folding lines, tucks and front stalls may vary from the CCC guidelines.
It can occur on the Boomerang 10, usually after big deflations or in cascading situations. The pilot should be familiar with the procedure for correcting it. On the Boomerang 10, there is a separate stabilizer/winglet main line that goes down to the A2 riser. This line usually becomes slack in the event of a cravat.
These manoeuvres should therefore be avoided. However, it is important to learn how to recognise the indications that a glider is about to stall so that you can take immediate action to prevent it. There are three different types of stall in paragliding. 25 /48 Boomerang 10...
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.
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. Boomerang 10 28 / 48...
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.
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.
Care The materials used in the Boomerang 10 have been carefully selected for maximum durability and performance. Nevertheless, following the guidelines below will keep your paraglider airworthy and will ensure a long period of continuous safe operation. Excessive wear is caused by careless ground handling and packing, unnecessary exposure to UV light, chemicals, heat and moisture.
“Packing the paraglider”. The plastic rods on the Boomerang 10 can all be replaced through small pockets. If you notice that a plastic rod has been damaged or misshapen because of incorrect use, this can be replaced by Gin Gliders or a Gin Gliders authorised workshop.
The Boomerang 10 has to be inspected for a trim check by an authorized GIN agent during the first 12 months. The Boomerang 10 should be regularly inspected by a qualified professional every 100 hours (including ground handling), or every 12 months, whichever comes sooner.
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.
Major repairs at the Boomerang 10, such as replacing panels, should only be carried out by the distributor or manufacturer. Small repairs to the glider Very small holes in the sail can be repaired with the sticky back tape provided with your glider.
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”...
The following CCC-Test-Template is published for anyone to check the wings. We recommend to download the official file from the link above to make the template easier to understand. Boomerang 10 40 / 48...
