Post by: Furball on August 18, 2005, 01:02:05 PM

How do they turn on the spot? (dont know the correct helicopter term for it - torque?)

I'd think it's simple enough... Angle one rotor left and the other right, and you'll pivot around the point between the two rotors....

Just a guess.

I think it has a cyclic control system, but that's the idea.

Yup, displaced tandems yaw by differential cyclic. Inline tandems oppose left-right cyclic, side-by-side tandems oppose fore-aft pitch cyclic.

And, for gee-wiz info: Coaxials, like any given Kamov product, yaw by increasing collective on one rotor disk, and decreasing it on the other.
