For us, that is enough for more than a full day of flying. The impressive towing performance of the ESW-2B is provided by an almost maintenance-free industrial-standard three-phase asynchronous motor, delivering more than 200 kW of power.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"689\" height=\"1024\" src=\"https:\/\/relaunch.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/Winde3-689x1024.jpg\" alt=\"\" class=\"wp-image-240\" style=\"aspect-ratio:0.6728561363546213;width:322px;height:auto\" srcset=\"https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/Winde3-689x1024.jpg 689w, https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/Winde3-202x300.jpg 202w, https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/Winde3-8x12.jpg 8w, https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/Winde3.jpg 697w\" sizes=\"auto, (max-width: 689px) 100vw, 689px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to automatic cable tension control, launches are safe, powerful, and optimally adapted to each type of aircraft.

The principle is similar to a child flying a kite while running across a field. Instead of running, the cable is wound onto a drum.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"912\" src=\"https:\/\/relaunch.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/CHR00513-01-1024x912.jpeg\" alt=\"\" class=\"wp-image-242\" style=\"aspect-ratio:1.1228031359703394;width:503px;height:auto\" srcset=\"https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/CHR00513-01-1024x912.jpeg 1024w, https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/CHR00513-01-300x267.jpeg 300w, https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/CHR00513-01-768x684.jpeg 768w, https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/CHR00513-01-1536x1367.jpeg 1536w, https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/CHR00513-01-13x12.jpeg 13w, https:\/\/www.flugsport-wien.at\/wp-content\/uploads\/2026\/09\/CHR00513-01.jpeg 1613w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">With a winch cable 1.5 km long, gliders can reach heights of around 500\u2013800 metres above the ground in this way.
