Gin's philosophy is simple: to design gliders that he, and any other pilot, will love to fly. This philosophy applies equally for a beginner glider such as the Bolero, as for the world-beating competition glider, the Boomerang.
Gin Gliders have made extensive improvements in the Boomerang9 compared to its predecessors. The Boomerang9 has a high aspect ratio and is a completely new design concept. Improvements have been made in line with GIN Gliders’ traditional values of higher stability and better performance.

These measures guarantee that pilots fly with the assurance that their wing meets the most exacting safety standards.
The main brake line lengths of the Boomerang9 are the same as on the sample that has been used for the EN/LTF certification test flights. These line lengths have been fine tuned by GIN test pilots, and it should not be necessary to adjust them.
Gin calculates and draws the plan of the glider with a distance between the carabiners of 44cm. DHV 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.
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.
4. Flying the Boomerang9 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.
Strong Wind Launch The reverse launch technique is recommended. Holding the brakes, turn around to face the wing passing one set of risers over your head as you turn. We suggest building a "wall" by partially inflating your glider on the ground, thus sorting out the lines thoroughly. Check the airspace is clear and gently pull the glider up with the A1 and A2 riser.
Asymmetric deflation In the event of encountering strong turbulence and suffering an asymmetric deflation (collapse on one side), the Boomerang9 will promptly and easily re-inflate without interference from the pilot, but the wing will turn slightly towards the collapsed side. This might be unwanted close to the ground or other gliders.
Spin In normal thermal flight, you are not very far from the limits of a spin. If a spin occurs, just let up the brakes and wait for the glider to surge forward, checking it with the brakes if it surges too far.
Big ears Due to the design, big ears is not possible on the Boomerang 9. B3 descent To increase your sink rate, first apply a little speed bar (about 20%) and then pull in the (outer) B3 lines simultaneously, firmly and progressively. To exit the manoeuvre, release the tips simultaneously and progressively.
unnecessary manoeuvres on the Boomerang9 to avoid weakening your glider and especially its lines! Landing with the Boomerang9 Select a familiar landing area free of obstacles and carefully note the wind speed and direction in the landing area. The minimum flying speed and big flaring reserve of the Boomerang9 will help you to make a soft landing in all conditions.
5. Care, Maintenance and Repairs The materials used in the Boomerang9 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.
In this case, the measured values should first be corrected to the same base of the Boomerang 9 check sheet data. If the lines are more than 2cm out of tolerance they should be replaced. If the lines are less than 2cm out of tolerance they can be re-trimmed either by taking (or releasing) loops on the maillons or by adding an extended maillon.
Major repairs, such as replacing panels, should only be carried out by the distributor or manufacturer. Environmentally friendly disposal of the paraglider When this paraglider cannot be used any longer after an extended period of time, you must ensure that it will be disposed in an environmentally friendly way. Please observe the existing regulations and laws in your country and do not just put a glider that is not airworthy anymore into a domestic waste bin.
