Open minded visitors : Welcome to this site

   You will discover that, such as birds and for reasons of safety, comfort and performance, the aerodynamical logic of an aircraft is to have “free” wings, always parallels to airflow and, due to the very understandable plans, you will have pleasure to built rapidly this concept, successfully tested since long time.

So… Thanks for your lucidity and ‘Welcome aboard’ !

The simplest (200 h of construction), the safest (no stall or spins, absorb turbulences and absolutely reliable) and the most economic of all aircraft (less than 4.000 $, with new 4-stroke injection engine)
