The UP SUMMIT X EN/LTF B is a high-end paraglider designed to deliver performance close to that of advanced C-class wings while maintaining the safety and certification standards of the B category. By adopting a 2.5-liner “hybrid” line layout combined with a newly developed Generation-X airfoil, it aims to offer a powerful blend of competitive glide, speed, and responsive handling with reduced pilot workload and enhanced passive safety. This wing targets experienced EN-B pilots who seek to push their cross-country flying to new heights without stepping into the higher demands of EN-C gliders.
Design and Technical Features
The SUMMIT X innovates with a center three-line layout tapering to two lines near the tips, cutting drag notably and enabling effective rear-riser (C-riser) steering for pitch and directional control. The wing's aerodynamic profile features extensive 3D shaping around the leading edge and a smooth trailing edge maintained by mini-ribs and a brake-tension system, improving collapse resistance and thermalling efficiency. Reinforcements like air-intake tension lines and internal rods ensure excellent pressure stability, especially under acceleration. This emphasis on aerodynamic optimization and structural integrity translates to a wing with significant glide efficiency and pitch stability.
Handling and Flight Characteristics
Launch and Ground Handling
Feedback consistently praises the SUMMIT X’s clean and predictable inflation. Pilots experience a steady, controlled canopy rise without issues such as back-hangs or aggressive launches, even in windier conditions. Its relatively compact surface and higher-than-average wing loading contribute to its manageable takeoff and top-landing behavior, making it accessible to confident B-class pilots on most sites.
In-Flight Comfort and Control
In flight, the wing balances a reassuring “gentle” feel with a dynamic, agile personality. While testers describe it as relaxation-friendly with pitch movements well-damped to prevent fatigue, others highlight its playful, freestyle-style agility allowing tight turns and immediate responsiveness. This dual nature means it is comfortable for long XC flights in active air while still fun and precise for energetic soaring. Pilots value the crisp steering with short brake travel, ideal for coreing narrow thermals with ease and for basic freestyle maneuvers.
Performance and Efficiency
Performance-wise, the hybrid 2.5-line scheme offers a visible reduction in line drag relative to traditional three-liners, helping bar efficiency and speed range. Though no dramatic glide leap is observed compared to modern top-level B wings, the SUMMIT X shows competitive glide and excels in strong winds due to its higher wing loading and robust handling stability on full bar. Test pilots report speed increases of 15–17 km/h on the speed bar, placing it near the top of the B-class performance spectrum.
Safety and Stability
The wing demonstrates solid pitch stability, especially on bar, which converts turbulent bubbles into lift rather than oscillations. While the tip sections are visually more active due to fewer line rows, this flutter is not considered unsafe but reflects the design’s emphasis on reducing drag and weight. Notably, big ears are easily deployed and self-reopening without frequent pumping, while spiral dives remain effective yet less stressful than on some other high-end B wings. Overall, the wing provides reassuring passive safety margins for experienced, active pilots.
Construction and Materials
The SUMMIT X uses a mixed fabric approach prioritizing durability where needed, such as Porcher Skytex 42 Everlast on stressed leading edges and lighter materials elsewhere, ensuring a solid feel without extreme weight savings. The unsheathed line set—Edelrid aramid and Liros Dyneema—reduces drag significantly, though it demands careful handling and routine inspections. The glider comes with quality accessories including a concertina bag, repair patch, and riser bags, reflecting UP’s focus on longevity and user care.
Target Pilot Profile
This wing is best suited for experienced EN-B pilots with good launch skills and active flying technique, usually flying 40+ hours yearly and pursuing serious XC challenges. It appeals to those who desire a high-performance, agile wing with a safety cushion, able to handle alpine or windy coastal conditions, and who appreciate a “freestyle” flying style. Pilots advancing from lower-B wings or occasional flyers should approach with caution and ensure proper training and comfort with its livelier handling.
Summary
The UP SUMMIT X EN/LTF B stands out as a sophisticated, next-generation B-class wing combining cutting-edge hybrid design and aerodynamic efficiency with practical user-friendly behavior. It strikes a fine balance between high-end performance and pilot comfort, suitable for ambitious cross-country pilots seeking top-tier results without the intensities of C-class wings. With excellent launch characteristics, efficient glide, advanced control options including C-handles, and robust construction, it delivers a rewarding package for skilled B pilots ready to elevate their flying.
