Gin Gliders ............................................
1. Gin Gliders 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 speedflying glider such as the YAK, as for the world beating competition glider, the Boomerang. No glider is released on the market without Gin’s complete satisfaction.
2. Introducing Speed Flying A. Speedflying, a new flying concept. A new flying Style is here: Speedflying; flying fast downhill. Over the last few years, Gin Gliders have been developing speedgliders for speedriding (launch by ski) and Speedflying (launch by feet). Now, Gin Gliders introduces an ultralight speedglider designed for foot launch, the YAK. B. Speedgliders, a new design concept. Speedriding and speedflying are both based on a new design concept developed by Gin Gliders.
3. Introducing the YAK The YAK is opening new horizons of piloting for expert and careful pilots with a lot of flying experience. The air, the speed and the safety are joined for a new dimension of flight… the possibilities are growing! The YAK will give you the possibility to return to the original soul of flight and also to open up new fields of practice. You will be able to fly down the mountain in wider aerological conditions with this simple and solid glider.
4. Before you fly Pre-delivery Inspection The YAK is delivered with a rucksack, the YETI harness (designed specifically for Light flights), inner bag, compression strap, repair tape and this manual. Your instructor or dealer should have made a test inflation followed by a test flight before delivery. . Risers and trimmers The back risers of the YAK are fitted with trimmers that enable the pilot to adapt the glider’s behaviour to match his level and the chosen slope.
Brake line adjustment The main brake line lengths of the YAK are the same as on the sample that has been used by the GIN R&D team. 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 and hold the handles on the knot. However, care should be taken to release the wraps in any extreme situation.
Weight range The YAK should be used in the weight range for which it was designed. The weight range is defined according to the pilot’s weight, including clothes. YAK Weight/ piloting level #15 expert #16,5 expert/ Advanced 45/75 kg #18 Advanced 75/100+ kg Essential In order to fly with this equipment, you should: *Have received theoretical and practical tuition for Speedflying. *Have sufficient practice, the knowledge and the experience necessary to use this glider correctly and safely.
5. Flying with the YAK We recommend that you first practice inflating your glider on a small training slope. Make your first flights with your new speedflying glider in gentle conditions in a familiar area. Preparation for launch Following a consistent method of preparation and pre-flight checks is vital for safe flying. We recommend the following: On arrival at the flying site, assess the suitability of the conditions: wind speed and direction, airspace.
Minimum sink rate and max glide ratio. The minimum sink rate can be found by pulling the brakes on by about 20 cm. the theoretical max glide ratio is obtained by trimming the back risers. Accelerated flight Once you have become accustomed to flying the YAK, you can practice using the trimmers. These enable you to increase the speed of your glider, and to have better penetration through the air in stronger wind conditions.
Landing with the YAK Choose a landing area free of obstacles. It is recommended to land with a full flair; it will enable you to obtain a zero vertical speed and an easy run at the end of the flair. Do not make your last turn at low height, or make a radical turn close to the ground. Do not approach too slowly with the back trimmer on and a lot of brake. The best landing approach is with the trimmers set to neutral and then use a proper flair to bleed of your speed.
6. Care, Maintenance and Repairs The materials used in the YAK have been carefully selected for maximum durability. Nevertheless, following the guidelines below will help keep your glider 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 Be careful of the following: Violent shocks to the upper surface (e.g.
Transport and Storage Moisture is the worst enemy of your glider, adversely affecting the ageing of fabric, lines and reinforcements. The YAK 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.
