Page 4: Gin Gliders
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 like the Zoom, as for the world- beating competition glider, the Boomerang. -
Page 5: Introducing The Boomerang 4
Rapid progression up the learning curve is enabled, as the pilot becomes acquainted with using the speed and performance of this wing. The Boomerang 4 will allow you to experience the full pleasure of free flight with the highest performance available today. -
Page 6: Manufacturing
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. Stringent quality control is made after each step, and all materials that go into each wing can be traced. -
Page 7: Before You Fly
3. Before you fly Pre-delivery Inspection The Boomerang 4 is delivered with speed system, rucksack, 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. -
Page 8: Break Line Adjustment
Brake line adjustment The main brake line lengths of the Boomerang 4 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. -
Page 9: Your Harness
Your harness The Boomerang 4 can be used with all harnesses with variable cross-bracing (GH type). 99% of harnesses produced after 1993 are of the GH type. Older harnesses with fixed cross-bracing (GX type) should not be used. Check with the manufacturer of the harness or your paragliding instructor if in doubt. -
Page 10: Flying The Boomerang 4
Light or Nil Wind Launch The Boomerang 4 inflates steadily in nil-wind conditions. Simply guide the glider with the A- risers, keeping your arms bent and hands at the level of the shoulders. Allow your arms to rise in an arc and wait for the glider to inflate and come above your head do not push the risers. -
Page 11: Line Knots Or Tangles
Active flying The Boomerang 4 has a high internal pressure, resistance to tucking and a base level of passive safety. However, it is recommended that you always practise an active flying style. This will help you avoid deflations in all but the most turbulent conditions. -
Page 12: In Turbulence
In the event of encountering strong turbulence and suffering an asymmetric deflation (collapse on one side), the Boomerang 4 will have a tendency to re-inflate by itself, but the wing will turn towards the collapsed side. This might be unwanted close to the ground or other gliders. -
Page 13: Losing Altitude
The glider can be steered while in big ears using weight shift alone. When you release the lines, the Boomerang 4's ears will come out on their own, or may require a short pump. Release the big ears at least 100m above the ground. If this is not possible, keep... - Page 14 Deep stall (parachuting, stable stall) The Boomerang 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. On some...

Page 15: Steering Without Brakes
Steering without brakes If a brake is not operational for some reason, you can steer the Boomerang 4 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. -

5. Care, Maintenance and Repairs The materials used in the Boomerang 4 have been carefully selected for maximum durability and performance.
