1. Gin Gliders Gin Gliders was formed in 1998 by paraglider designer annd competition pilot Gin Seok Song and his team of enggineers and test pilots. Gin’s philosophy is simple: to design gliders that he, and any other pilot, loves to t fly. This philosophy applies equally for an entry-level wing such as the Bolero 4, as for the world-beeating competition glider, the Boomerang. B No glider iss released to the markeet without Gin’s compleete satisfaction.
2. Introducing the Bolero 4 The Bolero 4 is a new concept in an entry-level 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 Bolero 4 offers outstanding security, with precise but forgiving handling. This allows the pilot to accurately feel the sensations of flight, and thus develop an active flying style.
Weight and drag have been reduced by using thinner yet very strong line materials and by the introduction of a new, hi-tech, light fabric. These and other innovations ensure that by purchasing the Bolero4, you are getting the best possible glider in its class. Manufacturing All GIN gliders are produced in the company’s own facilities using the most modern techniques. Highly skilled staff take extreme care during the entire manufacturing process.
3. Before you Fly Pre-delivery Inspection The Bolero 4 is delivered with speed system, rucksack, inner bag, riser cover, compression strap, repair tape and this manual. Your instructor or dealer should have made a test inflation followed by a test flight before delivery. Each Bolero 4 is checked for conformity with the EN and LTF tested specimen before it leaves the factory. Speed System The speed system increases the maximum speed by lowering the angle of attack with a pulley-guided, foot-operated system.
Flying with motor The Bolero 4 can be equipped with risers which have trimmers in addition to the accelerator system. The Trimmers are not certified for flying without a motor. For free flight, the trimmers should be deactivated and hooked into the carabiners. Length neutral Length accelerated Length accelerated trimmers open Risers A B C D (lower hang point) 52cm 52cm 52cm 52cm (upper hang point) 44cm 44cm 44cm 44cm (lower hang point) 39cm 41cm 46.
Brake linee adjustment The main brrake line lengths of the Bolero4 correspond too the ones used in the EN E and LTF test flights. These line leengths have been fine tuned t by GIN test pilots, and it should not be necessary to adjust them. In soaring flight, f it is common to fly f with half a wrap on the t brakes. However, caare should be taken to release the wraps in any extreme situation.
"X Load System" is a new compression system created by the GIN R&D team, using Hypalon material. Its concept is based on a 4 point cross bracing at the bottom of the rucksack to obtain an optimum distribution of weight." Your harness The Bolero 4 has been tested with a harness with a variable chest strap and without fixed crossbracing. Ancient harnesses with fixed cross-bracing are not suitable for flying with the Bolero 4 and should not be used.
body weight and your total flying weight will be around 20 kg. For paramotor flight the additional weight of the engine and fuel must also be taken into account. Pre-flight safety To fly this equipment you should: 9 Have appropriate practical and theoretical training and experience for this class of glider. 9 Have the necessary insurance and licences. 9 Be in your right mind, unaffected by extreme stress, recreational or prescribed drugs. 9 Only fly in conditions suitable for your level of paragliding.
4. Flying the Bolero 4 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: 9 On arrival at the flying site, assess the suitability of the conditions: wind speed and direction, airspace, turbulence and thermal cycles.
First flights with paramotor First try to get accustomed to the Bolero 4. You should make your first flights with trimmers set to the neutral position. When you fly the Bolero 4 in this trimmer position it feels like a normal paraglider. Apply normal brake pressure and try to find the point where the pressure becomes heavier. This point will be at around 25% of the total brake travel range.
turn and launch. In stronger winds, be prepared to take a couple of steps towards the glider as it inflates and rises. Line knots or tangles If you do take off with a line knot or tangle, try to get clear of the ground and any traffic before taking corrective action. Weight shift and/or counter brake to the opposite side and pump the knotted side with your brake. Be careful not to fly too slowly to avoid a stall or spin.
deflation fails to come out, pump the t deflated side with a firm and smooth pumpping motion. Let the glider regain its flying speed afterr it has re-inflated. Symmetricc deflation A symmetricc (frontal) deflation willl come out promptly without pilot input. The glider g will regain airspeed witth a small surge. If counter braking, be carefuul not to over-correct. Cravat / gllider wrapped arounnd lines A cravat occcurs after a severe deflation when the wingtipp becomes trapped in thhe glider lines.
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 Bolero 4 does not have a tendency to get into nor stay in a deep stall. Should this nevertheless occur, put your hands on the A risers and push forward to gain speed.
Although the noise of the wind around your ears may indicate the airspeed improves, the airspeed does not improve with big ears. You may use the speedbar in combination with big ears to maintain your forward speed but increase the sink. The glider can be steered while in big ears using weightshift alone. When releasing the lines, the Bolero 4’s ears will come out on their own. Release the big ears at least 100m above the ground.
is only a passive safety system. Standing up before landing is an active safety system, and is much more effective. Tow launch The Bolero 4 is suitable for towing by pilots who have the relevant towing certification. The Bolero 4 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.
If the wing starts to drop backwards, increase the pressure on both “A” risers to help it up, and as you increase power, try to keep a constant angle with the motor and maintain smooth power control. Any sudden changes will alter your course because of the powerful gyroscopic and torque effects. If the canopy is so far off to the side or behind that it cannot be recovered, kill the engine, abort the take-off and reassess the launch conditions.
* All control inputs should be smooth and progressive. * Don’t attempt to take off if the canopy isn’t roughly level overhead. Dangerous oscillations may result if you apply full power with the canopy off to one side. * Keep your undercarriage down until you are definitely flying! * The faster the trim setting, the more brake the glider will need to get off the ground. Speed systems may cause problems when clipping in.
* Adjust the trimmers to dampen it out Weight shift is the best counter. Oscillation usually occurs on high power settings - more power and a larger propeller cause more oscillation. It could be that your control inputs are amplifying the oscillation. In this case, throttling back a little and flying hands-off should take care of the problem.
fully coordinated, smooth turns, much like those possible on a three axis aircraft. Points to Note:* Remember, the trimmers and speed bar controls are extra items for your pre-flight checks! Landing There generally seems to be two philosophies about landing a paramotor - either with or without power. Power-off Landings Cut all power at about 50m and glide in like a paraglider.
During take-off ALWAYS ensure that your wing is definitely flying with enough air speed, before opening the throttle or pulling on any brakes during any launch. If it does happen that you have managed to leave the ground but are not fully flying, DO NOT add more power and more brakes but smoothly come off them, If the wing does not accelerate, just land. Re-assess the conditions as it may well be you are trying to climb out through a wind gradient.
5. Care, Maintenance annd Repairs The materiaals used in the Bolero 4 have been carefully seelected for maximum durability. Neverthelesss, following thhe guidelines below will keep your paraglider airworthy and will ensuure a long period of continuous safe operation. Excessive wear is caused by careless c ground handlinng and packing, unnecessaryy exposure to UV light, chemicals, heat and moisture. Ground haandling The followinng should be avoided: Violent shoccks to the upper surface (e.g.
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 lukewarm 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.
6. Reference Testing and Certification The Gin Glider Bolero 4 has passed EN standard A and LTF A. This is the safest class of paraglider. The Bolero 4 has also passed load tests and shock tests with a load exceeding 8G of the maximum weight in flight.
