The '''Windtech Quarx''' is a [[Spain|Spanish]] single-place [[paraglider]] that was designed and produced by [[Windtech Parapentes]] of [[Gijón]]. It is now out of production.<ref name="WDLA04">Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 36. Pagefast Ltd, Lancaster OK, 2003. {{ISSN|1368-485X}}</ref>

==Design and development==
The aircraft was designed as an advanced intermediate glider and was produced in two generations, the Quarx1 and Quarx2. The models are each named for their approximate wing area in square metres.<ref name="WDLA04"/>

The design was optimized for a wide speed range and was marketed to pilots "from the weekend recreational flyer to the competition pilot".<ref>{{cite web|url = http://windtech.es/en/products/previous/quarx1/index.html|title = Quarx1 |accessdate = 24 November 2016|author = [[Windtech Parapentes]]|year = 2016}}</ref>

The glider wing is made from Porcher Marine Skytex 44 g/m2 [[nylon]] fabric. The rib reinforcements are 310 g/m2 [[Dacron]], with the [[trailing edge]] reinforcement fabricated of 175 g/m2 [[polyester]]. The lines are all sheathed [[Kevlar]] and 1.1 and 1.7&nbsp;mm in diameter or, optionally, 0.6 and 0.9&nbsp;mm micro unsheathed lines. The risers are made from 20&nbsp;mm wide Polyamida strapping.<ref name ="specs">{{cite web|url = http://windtech.es/en/products/previous/quarx1/data.html|title = Quarx1 technical data|accessdate = 24 November 2016|author = [[Windtech Parapentes]]|year = 2016}}</ref>

Reviewer Noel Bertrand noted in a 2003 review that the Quarx2 had been "very successful".<ref name="WDLA04"/>
