The crucial breakthrough for rotorcraft was the Hafner ARIII
Gyroplane
developed by Austrian Raoul Hafner in Britain in 1935. This
introduced all the features of the modern helicopter, hinged rotors,
and swashplate along with cyclic and collective controls.

Tomy tricks. Lets quote that in complete context:

I didnt quote it at all

In 1935 Austrian-born Raoul Hafner flew the first combined
cyclic-and-collective control system on an autogiro with articulated
blades. Although this machine was NOT CAPABLE of HOVERING, it marks a
milestone in helicopter technnology.


And your point is ?
