Anyone have a clue as to how it controls yaw?

But how can it be called a helicopter if it has a fixed pitch rotor?

These things outta be called something else...

I'm also having a little trouble calling it a helicopter; but thanks for the
link, which provided the following answer to the frequently asked question
about yaw:

Yaw is controlled through a differential gear within the transmission.
An electric motor adjusts the positioning of a differential gear, which
changes the speed of the counter rotating blades in relation to each other
causing torque on the helicopter which results in yaw in either direction as
directed by the pilot.
