An EN-C two-liner for ambitious cross-country pilots
The Advance TAU DLS is positioned as a high-performance wing for cross-country and competition pilots looking to maximize every meter of lift. Rated EN-C, it commits to a two-line profile with an unprojected aspect ratio of 4.94, delivering refined glide without compromising the durability expected in this category. Advance labels it a “Sports-Class Racer,” which translates to direct responsiveness and strong thermal efficiency.
DLS Technology and Edelrid Lines
The airframe relies on Advance’s Durable Lightweight Structure (DLS) technology. By targeting load-bearing zones and optimizing geometry, the manufacturer reduces fabric weight without compromising attachment points. The wing uses universal Skytex 38 and 32 for the canopy, reinforced with hard-profiled sections and a rear panel of DOKDO-10DSF. Risers incorporate Technora tapes and an Easy Connect system for secure attachment. The Edelrid Pro Dry lines are semi-transparent, colored, and treated to repel water over 60% more effectively than previous generations, while maintaining dimensional stability and high tensile strength.
Weight Ranges and Loading
Six sizes, from 19 to 27, cover a wide pilot range. Advance has calibrated “Seamless Weight Ranges” to avoid ambiguous overlaps. For size 21, for example, the certified weight range spans 77 to 93 kg, while the ideal range sits between 81 and 90 kg. This split ensures consistent wing loading across sizes, a key factor for maintaining predictable handling during long flights. Total wing weight ranges from 4.00 to 5.40 kg depending on the size, confirming the weight savings delivered by the DLS structure.
Pilot Input and Vigilance
Active brake steering is assisted by a B-handle and low-friction brake pulleys. The shark-nose profile and trailing-edge mini-ribs help stabilize entry into thermals and maintain heading in moderate turbulence. Brake pressure remains crisp, allowing precise centering in thermal cores. The EN-C rating is a passive safety framework: it does not compensate for inexperience or poor air mass reading. This wing demands active piloting skills and the ability to manage incidents across varying conditions.
The wing ships with a tubebag, repair kit, and mini antenna. Stock is supplier-ordered with variable lead times.
