Hello,
(Sorry for the bad translation, I do not write English).
Thank you Abid for the compliment.
Brian,
The wing generates an important portance, capable of supporting, in high speed, more than half weight of the machine and his pilot. Without variation of blades pitch, the rotor would slow down dangerously provocating an exaggerated beating. The mechanical and automatic system (without intervention of the pilot) allows this variation, proportionally in the load :

John,
The construction little progressed since the creation of the web site. The tries are planned in 2016, I hold you informed.
