Building a Hydrofoil for a Laser Sailboat

This video is about the whole building process of a electronic Hydrofoil for a Laser sailboat. The last video documented not to whole process. The Ruderfoil and the electronic height-regulation-system were missing. All this was partially my graduation work from the "Gymnasium" (like highschool) and partially from the the "Nationaler Wettbewerb, Schweizer Jugend forscht" (Swiss Youth Science). Thanks to all the people who made this project possible!
