The new Golden4 is the latest wing from the Gradient development team. The wing is the follow-up to the most successful Gradient model ever, the Golden series. The result is pure style, an aerodynamic design with an incomparable 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 relax and quickly start to fly in harmony with the wing.
It makes the Golden4 a truly reliable partner. Flying becomes intuitive, leaving your mind free to concentrate on making decisions about your flight.
Flying the Golden4 starts with the typical, easy take-off characteristics Gradient pilots all over the world appreciate.
In the air, the Golden4 thermals flat, even when flying small circles. The wing reacts immediately to weight shifting and has precise brakes. Well-balanced wing dynamics and a defined stall point give this basic intermediate glider typical Gradient handling.
The glider also behaves in a calm and predictable way in extreme situations, leaving you confident of your safety while you regain normal flight – no matter if it was you or turbulence that caused the trouble.
Gradient’s well-proved DDsystem, as used on the Aspen4 and Nevada gliders, have made it possible to develop an basic intermediate glider without compromises in stability, behavior or performance for its class. The result is a light glider with aerodynamic improvements in safety and performance too.
The Golden4 has three main line levels, a system Gradient has uses for years. Careful selection of lines and materials 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 and this combined with a self-trimming system and different line materials mean the glider keeps its long-term geometry. Meanwhile, optimal cell opening sizes and position ensure efficient air intake at a very wide angle of attack.

The Golden4 is the first Gradient glider where we have used Everlast, a double-coated Porcher material. Everlast was developed by Gradient in co-operation with Porcher Sport, and this exclusive material provides gliders with long-term stability and durability.
Inside, the inner working of the profile is a result of Gradient’s sports class glider development. Using the latest software means the tension of the profile could be increased without compromise. These improvements have allowed the Gradient team to tune the whole wing without compromising safety. Small, simple details make this glider complete.
The Golden4 is another high-end product, the result of Gradient’s successful design philosophy that in the air, progress means simplicity. Finding elegant solutions to creating that simplicity is the art of building a Gradient wing.
