Orion wing section is 15% Cees, the 19% section was a one off experiment, that didn't work. Read Ed's words again. I realise English is not your first language, and things get lost in the translation. Check you Orion drawings if you don't believe me. There is a world of difference between a 15% wing and a 19% wing, as you fly both you should know that...
