Golden4 - EN B certified paraglider

After a worldwide success of the predecessor model Golden3 Gradient's new intermediate glider Golden 4 comes with certification EN-B, LTF 1-2, sticking to the lower end of this category. The glider will be available in five sizes (22, 24, 26, 28 and 30) covering a wide weight range of pilots. Golden4 is a completely new design developed meticulously over a long period of time and finally chosen by a detailed in-flight comparison from different prototypes.

The result is a pure aerodynamic design with unmatched variety of uses and the potential to meet the demands of all kinds of pilots. The agility lift performance and speed of the Golden4 are backed up by strong passive safety. Gradient’s typical sensitive handling and immediate feedback means pilots can relax and quickly start to fly in harmony with the wing.  This makes Golden4 a truly reliable partner. Flying becomes intuitive, leaving your mind free to concentrate on making decisions about your flight. Golden4 is safe enough for a beginner while being able to satisfy an experienced pilot by performance as well. The use of Everlast fabric on the most exposed parts of the canopy makes this glider almost aging-proof. Golden4 as your first glider may be one of the best investments in your hobby you've ever made.

Characteristics

Flying Golden4 starts with the typical, easy take-off characteristics Gradient pilots all over the world appreciate. In the air Golden4 thermals flat, even when flying small circles. The wing responds immediately to weight shifting and it has precise brakes. Well-balanced wing dynamics and a defined stall point give this intermediate glider the typical Gradient handling. The glider also behaves in a docile and predictable way in extreme situations leaving you confident of your safety until you regain normal flight – no matter if it was you or turbulence that caused the trouble. In comparison with Golden3 you will find a noticeable improvement in glide, especially on speed bar, while max. speed and best sink rate remains roughly the same.

Construction

Gradient’s well-proved DD system, as used on the Aspen4 and Nevada gliders, has made possible to develop an intermediate glider without compromises in stability, behavior or performance for its class. The result is a light glider with improvement in safety and performance area as well.
Golden4 has three main line cascades, a system Gradient has used for many years. Careful selection of lines and fabrics means the wing-loading is optimized in flight in any situation. Progressive line diameters along the span and chord are already standard in Gradient wings. Combined with a self-trimming system and different line materials mean the glider keeps its geometry for a long time. Meanwhile, optimal cell opening sizes shape and position ensure optimal internal pressure at wide angles of attack.

Everlast

The Golden4 is the first Gradient glider where we have used Everlast, a double-coated Porcher Marine fabric. Everlast has been developed by Gradient in co-operation with Porcher Sport. This exclusive material provides gliders with a long-term stability and durability. The inner working of the profile is a result of Gradient’s sports class glider development. Using the latest software helped us to increase the tension of the profile without compromising structural strength. These improvements have allowed the Gradient team to tune the whole wing precisely and safely. Small, simple details make this glider what it is: a pleasure to fly efficient machine with a high degree of passive safety.
Golden4 is another result of Gradient’s successful design philosophy that in the air, progress means simplicity. Finding elegant solutions for achieving that simplicity is the art of designing a Gradient wing.


Golden4 can be also supplied with special risers as a paramotor version.

Note: Gradient has decided to end the rat-race in publishing of performance data. The rubbery nature of these figures makes it impossible to obtain or prove them with any acceptable degree of accuracy. In the last few years this situation lead to publishing one guesswork after another and there was always a room for improvement on the paper. In the end the bolder the manufacturer, the more dazzling figures they produced. This reality has been well known to everybody in this industry for a long time and it is time to pull the plug on this escalating image building hysteria. Some other manufacturers are following suit already and we can only hope more will join that number. If you want to see the usual "precise figures", sorry, we can't help - we don't have them. We don't feel it is fair publishing any figures in the absence of fixed standards for recording of performance data in this industry.
