I think this is what the title of the video says, Passaro Atacando autogyro seems to be Portuguese for "A bird attacking the autogyro"
As an aside I have pondered setting up a remote flying school for some time. Have a couple of 2/3 or 3/4 scale Bensen autogyros (or Calidus, MTO ... ) equipped with first person view and let people from all over the world fly them via the internet
