Just started on my next building project. This one will be all Depron, a material that I never used before. So there will be a learning curve for me. When you find the plans on the Internet they may be in French or German. The designer is Thomas Buchwald. I have the Chrome browser on my Mac that has an option to translate web pages in another language. You may have a similar ability on your computer. The original design has about a 23″ wingspan, which is on the small side for me. So I went to Kinkos and had the plans blown up 200% which yields about a 46″ wingspan. Here are a few links to Jupiter Duck pages.
