No competition for the first one to pilot a helicopter, but the website might well be a challenge to many of you as it is written entirely in French by Pescara's son.
There are some interesting technical notes and a number of pictures of his machine, which it is hard to believe actually flew. However, we all owe him very much as I believe he was possible the first to tackle the complex task of varying the pitch of the rotating blades and the direction of tilt of the whole rotor system.
