Violent shocks to the upper surface e g when the canopy crashes to the ground leading edge first whilst ground handling Dragging the glider along the ground Stepping on the lines or canopy The Kevlar line inside the sheath can take lots of pulling force without stretching but is sensitive to bending with small radius Opening your wing in strong winds without first untangling the lines UV damage Avoid leaving the glider out in the sun unnecessarily UV rays from the sun degrade paraglider cloth Packing instructions We advise you to pack the glider accordion wise as shown in the diagram This packing procedure takes slightly longer and requires an assistant but it conserves the rigidity in the profile reinforcements Ip D Since folding the glider weakens the materials pack the glider as loosely as possible Transport and Storage Moisture is the worst enemy for your glider adversely affecting the ageing of fabric lines and reinforcements The Zoom should therefore be kept dry and cool Do not pack the glider away for a prolonged period if it is damp sandy salty or if other objects have entered the cells Always allow it to dry naturally before storage in a dry room Leave the rucksack zip open whenever possible to allow residual moisture to evaporate and do not transport or store the glider in the proximity of chemicals such as gasoline paints or other solvents Cleaning Use only lu
5. We recommend setting a distance of 42cm to 50cm between the carabiners depending on the size and design of the harness There is no need to fly with a tight chest strap setting with the Zoom as there is no tendency for it to feel unstable unlike older gliders Certified Weight Range The Zoom must be flown within the certified weight range given in the reference section at the back of this manual The weight range is quoted as the total weight in flight i e the weight of the pilot glider harness and accessories The easiest way to check your total weight is to stand on weighing scales with all your equipment packed into your rucksack Pre flight safety To fly this equipment you should Have appropriate practical and theoretical training and experience for this class of glider Have the necessary insurance and licences Be in your right mind unaffected by extreme stress recreational or prescribed drugs Only fly in conditions suitable for your level of paragliding Wear suitable head protection use a certified harness and emergency parachute Make a thorough pre flight check zoom 9 4 Flying the Zoom We recommend that you first practice inflating your glider on a small training hill or flat ground Make your first flights with your new paraglider in gentle conditions on a familiar flying site Preparation for launch Following a consistent method of preparation and pre flight checks is vital for safe flying We recommend the following
6. the airspeed does not increase by pulling big ears In fact it decreases by about 5 km h You may use the speed bar in combination with big ears to maintain your sink rate but increase forward speed The glider can be steered while in big ears using weight shift alone When releasing the lines the Zoom s ears will come out on their own Release the big ears at least 100m above the ground If this is not possible keep the big ears in until you flare for landing rather than letting them out on the approach This is a safer method because of a possible wind gradient close to the ground and your low airspeed high wing loading with big ears in 14 GIN Spiral dive The spiral dive should be considered an extreme manoeuvre Practice spiralling with caution and lesser sink rates to get a feel for the Zoom s behaviour Weight shift and pull the brake on one side gradually Let it accelerate for two turns and you will enter the spiral dive Once in the Spiral you can control your descent rate and bank angle with weight shift and the outer brake WARNING A pilot who is dehydrated and or not accustomed to spiralling can lose consciousness in a steep spiral dive As with all types of aircraft we advise you to assist the glider to exit from the spiral dive in a controlled manner Let the glider decelerate for one or two turns by applying outer brake and or weight shift B stall To quickly loose altitude without straining your body with G for

12. at full travel It is important to have your accelerator system correctly routed through your harness and attached to the risers with the supplied Brummel hooks The length of the speed bar should be initially adjusted while on the ground sitting in the harness so that the legs are fully extended at the point of full accelerator travel It is helpful to have an assistant hold the risers taut while making this adjustment Subsequent fine tuning can be done on the ground following the first flight with the speed system If in doubt about this procedure consult your instructor or dealer e Ta TTT eae zoom 7 Brake line adjustment The main brake line lengths of the Zoom are the same as on the sample that has been used for the DHV certification test flights These line lengths have been fine tuned by GIN test pilots and it should not be necessary to adjust them In soaring flight it is common to fly with half a wrap on the brakes However care should be takento release the wraps in any extreme situation If you do need to make adjustments to suit your harness body and flying style we strongly recommend that you test fly the glider with every 2cm of adjustment There should be a minimum of 10cm of free brake travel when the glider is flown hands off This prevents the brakes being applied unintentionally when the speed system is fully engaged We recommend a double sheepshank or a bowline knot for the brake handle attachment as shown
13. ce you can use the B stall Reach up to the B risers just below the maillons and twist your hands while gently pulling It will be difficult at first but become lighter the more you break the airfoil Once pulled do not release immediately The glider needs to settle into a stable B stall before releasing On exiting the B stall the Zoom has a very gentle dive without deep stall tendencies We advise you to release the B stall symmetrically with both hands in a decided manner Full stall dynamic stall This is an extreme manoeuvre and there should never be any need to perform one Do not take wraps with your brakes before entering a full stall Keep your hands close to your body during the stall and lock them under your harness seat plate if necessary In a stable full stall the canopy will oscillate back and forth Before releasing the stall raise your hands slightly and evenly to fill the glider with air If possible let the brakes up when the glider is in front of you to avoid excessive surge The Zoom will slow down the surge on its own but you may counter brake the dive briefly for comfort if needed and then let up the brakes to regain airspeed Be careful to not stall the glider again when damping the surge Never attempt a stall and then change your mind and release the brakes as the glider will surge radically Deep stall parachuting stable stall The Zoom does not have a tendency to get into nor stay in a deep stall Should this n
14. ders Gin Gliders was formed in 1998 by paraglider designer and competition pilot Gin Seok Song and his team of engineers and test pilots Gin s philosophy is simple to design gliders that he and any other pilot will love to fly This philosophy applies equally for a cross country intermediate wing such as the Zoom as for the world beating competition glider the Boomerang No glider is released to the market without Gin s complete satisfaction Gin has over 15 years experience of designing and manufacturing paragliders and is backed by an equally experienced team both within the company in Korea and throughout a worldwide network of distributors and dealers The GIN Team dominated the Paragliding World Cup from 1998 to 2004 and has had countless other competition successes in World Cups World and National Championships This high level of expertise provided by dedicated professionals ensures that you get the best possible product support and after sales service 4 E GIN 2 Introducing the Zoom The Zoom is a new concept of cross country intermediate wing Designer Gin Seok Song has drawn on all his years of experience to produce a wing that is uniquely in tune with the needs of today s pilots The Zoom offers exceptional performance combined with a high security level and precise and dynamic handling This allows the pilot to accurately feel the sensations of flight and thus develop an active flying style Rapid progression u
15. evertheless occur put your hands on the A risers and push forward to gain speed On some modern harness accelerator setups you can reach the speed bar without using your hands If so push the speed bar Never try to steer out of a deep stall You can recognise a deep stall by the glider getting mushy and the airflow around your ears decreasing This situation is usually achieved by flying in turbulence or exiting a deflation with too much brakes applied A wet glider also has a higher deep stall tendency If you pass some rain accelerate a little and never induce big ears inthis situation Steering without brakes If a brake is not operational for some reason you can steer the Zoom with the D risers Add steering input by weight shifting in your harness Be careful not to steer too much with the riser to avoid any possibility of a spin Aerobatics The Zoom is not designed for aerobatics and in most 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 Landing with the Zoom Select a familiar landing area free of obstacles and carefully note the wind speed and direction in the landing area The low minimum flying speed of the Zoom 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 Before landing slide your legs forward
16. in the harness so that you adopt the standing position NEVER land in the seated position it is very dangerous for your back even if you have back protection which is only a passive safety system Standing up before landing is an active Safety system and is much more effective Tow launch The Zoom is suitable and certified for towing by pilots who have the relevant towing certification The Zoom has no tendencies towards deep stall parachuting There is sufficient margin to counter steer the glider in a normal towing situation Make sure you use proper equipment experienced personnel the recommended techniques and all relevant safety precautions for towing Motorized flight Paragliding certification does not include motorized flight However motorized flying with the Zoom is possible due to its very easy take off characteristics good performance stability and extraordinarily good handling Always use certified combinations of engine harness glider Always check with your federation if in doubt 16 MGIN 5 Care Maintenance and Repairs The materials used in the Zoom have been carefully selected for maximum durability 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 Ground handling The following should be avoided
17. kewarm water and a soft cloth to clean your wing Never use any abrasive materials or detergents Only clean the wing if it is absolutely necessary e g after a landing in salt water Maintenance Inspections GIN Gliders require the Zoom to be inspected by an authorized Gin agent after every 100 hours flying time or every year whichever is sooner To extend the validity of the DHV G tesiegel certification a full inspection is required for the first time after 30 months and then every 24 months thereafter The maintenance instructions which are included in this manual have to be observed This is valid for the Zoom Race as well as for the Zoom with normal sheathed lines A full inspection will give you peace of mind and extend your glider s lifetime Additional inspections should be performed by a qualified person following a crash or violent landing on the leading edge or if you note a deterioration of performance or behaviour You should also check for any damage to your lines sail risers and connectors before each flight Repairs Very small holes in the sail can be repaired with the sticky back tape provided with your glider Damaged lines should be replaced by your GIN dealer Before fitting a replacement line check it for length against its counterpart on the other side of the wing When a line has been replaced always inflate the glider on flat ground to check that everything is in order before flying Major repairs such as repl

20. othly apply brake and or weightshift on the appropriate side until you feel pressure return In all cases maintain adequate airspeed and avoid overreaction In turbulence Deflations of the canopy can occur in strong turbulence The Zoom will recover without pilot input in most situations so whenever in doubt let up the brakes and let the glider fly 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 Asymmetric deflation In the event of encountering strong turbulence and suffering an asymmetric deflation collapse on one side the Zoom will easily re inflate without strong interference from the pilot but the wing will turn towards the collapsed side This might be unwanted close to the ground or other gliders Maintain your course by weightshifting away from the collapsed side This action can be aided by applying a little force on the brake opposite to the deflation This will normally be sufficient for recovery However if the deflation fails to come out pump the deflated side with a firm and smooth pumping motion Let the glider regain its flying speed after it has re inflated If you have a big collapse especially when flying accelerated you must observe the following When a big collapse happens due to the difference in weight and inertia of the canopy and pilot the pilot will continue to travel
21. p the learning curve is enabled as the pilot becomes acquainted with the myriad of different movements and moods of the air The Zoom will allow you to experience the full pleasure of free flight without ever compromising your safety For Pilots Who The Zoom is an ideal cross country glider and is suitable for the experienced pilot who flies frequently and wants a high performing glider with a good safety margin The Zoom is designed for all kinds of flying from ridge soaring to thermalling but is optimized to go further in cross country Cutting edge Design Gin has made extensive improvements in the Zoom compared to it s predecessors Performance take off and handling characteristics have been improved without sacrificing security Wind tunnel research and new software to optimize the shape of the leading edge has produced an even cleaner airfoil A special shape for the reinforcements has been introduced This improves take off characteristics performance and increases the lifetime of the canopy The brake line layout is designed for fast and flat turning with proportional brake pressure for light and direct handling This enables efficient and easy climbing in thermals as well as using weak lift when ridge soaring Weight and drag have been reduced by using a new hi tech lightweight fabric and less metres of line The Zoom is available in 2 versions The normal version with sheathed lines and the Zoom Race version equipped wi
