Thanks for the link! This striking box-wing airplane is all carbon fiber composite and can start only from water. It is probably the most interesting airplane proposal at this fair. The maiden flight is planned in a few weeks. Because of severe winters in Finland, flight testing was made only with scale R/C models. I'm mystified as to how they can promise deliveries this summer if they haven't even had a full-scale flight yet. Can you comment on their production optimism? Also, I can't see any control surfaces for pitch or roll. What am I missing?
