The Summit XC4 is a high-end EN B wing that is very easy to fly, and even more to the point, it is a wing that is very easy to fly far on. The handling is close to that of our popular high-end EN C wing, the Trango XC3, meaning it will communicate with its pilot, and let them know precisely what is going on where, without feeling nervous in the process. The glide at high speeds, critical for headwind performance on XC flights, has been improved compared to the Summit XC3, and with the light and efficient speed system and the very stable aerofoil there is simply no reason to hang around - just mash that bar, comfortable in the knowledge that you can control any forward pitch with the C-handles even before they turn into proper surges.

  • New Generation "sharknose" Aerofoil, to maintain optimal internal pressure at all angles of incidence,
  • FSS* and RSS to maintain aerofoil integrity at all angles of incidence as well as improve collapse resistance,
  • New riser design with efficient C-steering ability,
  • Optimised aspect ratio of 4.8 (projected)**, to improve gliding performance and energy retention on fast, turbulent glides,
  • Brake Tensioning System (BTS2), helps us to achieve the class-leading climbing performance and improves handling,
  • BB pulleys used throughout on the speed system for a soft, efficient speed bar,
  • Speed system which changes the AoA differently across the span, leading to more stability at high speeds, rare collapses and more benign reactions to collapses (hence the EN B rating),
  • Our 3D panel shaping leads to less wrinkles in the canopy, better performance and higher collapse resistance,
  • Low-drag line layout means minimum drag and better performance,
  • Swept-back wingtips for improved handling, better climbing,
  • Mini ribs in the trailing edge for perfect trailing edge definition, improved handling and climbing, and a more comfortable ride,
  • Optimised combination of Dyneema and Technora lines for best longevity and a stable AoA even in strong turbulence, no unwanted pitching upon thermal entry,
  • Handling and feel a perfect mix of Summit XC and Trango XC Series, meaning extreme efficiency with high fun-factor!
