In the week after i published the first pictures of the wing, i was about to order the wing parts. Quickly i noticed that the alu plates are totally cheap when compared to the tubes, which i needed for the spars. They were really expensive! So ...i asked Predrag Devic and his team to redesign the wing. And the result amazed me.
The D-tube is easy to assemble on a long table. Afterwards the rear part of the ribs can be mounted to the D-tube and kept at distance with the rear spar parts.
This is a really what i would like to make myself.
Once i have the parts list i order and i start building it once i have the parts delivered. While waiting i can search for good CNC water-cutters and good suppliers of raw materials.
