The '''Windtech Tonic''' 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 Tonic was designed as a beginner to intermediate glider for new pilots. The models are each named for their approximate wing area in square metres.<ref name="WDLA04"/>

The glider was designed to be easy and smooth to inflate and launch and to fly with a high degree of stability and resistance to collapses.<ref>{{cite web|url = http://windtech.es/en/products/previous/tonic/index.html|title = Tonic |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 180 g/m2 [[Dacron]], with the [[trailing edge]] reinforcement fabricated of 175 g/m2 [[polyester]]. The lines are all sheathed [[Kevlar]] of 1.1 and 1.7 mm diameter. The risers are made from 20 mm wide Polyamida strapping.<ref name ="specs">{{cite web|url = http://windtech.es/en/products/previous/tonic/data.html|title = Tonic technical data|accessdate = 24 November 2016|author = [[Windtech Parapentes]]|year = 2016}}</ref>
