Gradient have developed a special tool for ambitious XC tandem pilots and record-seekers: the BiGoldenXC. The sporty brother of the new BiGolden2, the wing differs slightly from the serial Tandem. A slightly bigger span of the profile improves performance, speed and sinkrate. The drag is reduced by the use of special competition tandem lines, and glide ratio in high speed gliding could be improved by using a competition trimmer system. The wings is slightly smaller than the BiGolden2 42. Gradient cite the BiGoldenXC’s strengths as an even more agile handling and a sport class-like effectiveness in thermals.
