Windtech Tonic
# Windtech Tonic

The Windtech Tonic is a Spanish single-place paraglider that was designed and produced by Windtech Parapentes of Gijón. It is now out of production.

## 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.

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.

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.
