In our workshop in Aachen we are currently putting building-blocks together.
Currently, we are working on wooden framework. Newt step would be metalworks and finally fiberglass.
It is important to say that the prototype will be made out of wood, in order to prove our concept. For final product, modern materials will be used, including HDP and carbon fiber.
By the end of the year Butterfly should touch the water.
