With windsurfing being one of my passions i found the "kitewing" (http://www.kitewing.com/), a combination between a surf-rigg and a hang-glider. Funny thing :) ... decided to build one by myself.
Here pics from the final design and development :)
Ok, looks good so far.
For now i was able to only test it shortly on a small path, during rain and with very mixed wind and it worked ok. After this first test i optimized some tubes and now i am waiting for wind .... I plan to take it with me to one of the next surf-trips to the dutch coast. (will post a video from the next session)
(afaik) Kitewing is trademark of Kitwing Sports Ltd. I do not have any associations with this company but just like their idea and product
