    Australia just scrapped theirs after a few people died in one.

    They seem inherently unstable. One fan stops working at the same speed as the other and wheeeee.

      I read that the rotors share a common drive shaft that runs all the way across to keep them locked in sync and so one engine can power both equally. I guess they feather the blades differentially to control bank angle?

        Not an aeronautical engineer, but that’s how all helicopters work in general, they change rotor pitch with constant angular velocity.
