Pescara Number 3 Helicopter. Oh Brother.

Pescara No. 3 Helicopter

Three times is a charm that’s how many times Spanish engineer Raul Pescara had to try to successfully build a co-axial rotor helicopter. In 1923, the third model, built in France could sustain flight of up to 10 minutes. Forward motion was slow and required tilting the rotors forward as there was only one engine and no engineering built in for forward motion. Still, I bet it was loud.

The two pictures are clearly not of the same machine, the top one is what is now called a quad-copter, the bottom, a coaxial, counter-rotating one
