UP are expecting to start delivering their new Summit XC3 in mid-April.
The glider is a high-level EN B wing and is aimed at, “experienced cross country pilots who just cannot get enough performance from their EN B wing”.
The first gliders in size Medium will start shipping then, with other sizes expected in May.

Pilots who loved the Summit XC2 will feel right at home on the new Summit incarnation. It has the same reassuring feel, but being a completely new design it does offer a sharper handling and quite a bit higher performance figures in real-life flying.
Speaking of performance, the Summit XC3 is a wing designed with top performance in mind. The flat aspect ratio of 6.3 is high for this class, but with the design being quite a high-arc one the projected A/R is less extreme, to the benefit of handling and safety.
Traditionally, high aspect ratio gives an advantage in light lift but is somewhat penalised in high-speed glides, since the extra lines needed to keep all that span in check add parasitic drag to the configuration especially at higher speeds.
Our R&D guys have addressed that oxymoron by refining the line layout so that the Summit XC3, in spite of the high A/R, has even less lines than wings with much lower A/R – this translates into the best of both worlds; amazing thermalling properties AND top performance at high speeds.
