this helicopter with 2 opposing direction rotors flew over me and made a lot of noise on its way to the airport. Also called coaxial helicopters as opposed to tandem rotos (separate axes). I dont believe any claims that they are quieter then single rotors.

  • @kokfah The blades come close, but no. There is sufficient spacing between them.

  • there is one here too.. and they really makes loud noise. wonder if the blades will hit each other?
