Controlling the pitch of the blades is how most helicopters work.

Probably wasn't clear above, I'm saying they weren't using a swashplate (most helicopters) they were using this little tiny tab attached to the rotor that could be controlled.

Yes, but that's using an external actuator, rather than weights that pull the blades to their new angle.
