Well said. I know what you mean about the complexity of the rotor mechanism, but I’m not really well-versed in the details.

In my early teens I put together one of those plastic models of a twin rotor helicopter. Not one of the big Chinooks but the eggbeater type that had intermeshing rotors close to each other. It made good sense because the opposite direction spin counterbalanced so that you didn’t need a rear horizontal rotor.

It suddenly occurred to me that I didn’t see much of those later. I did a search and found this. Interesting reading:

The Kellett XR-8 (later redesignated XH-8) was a helicopter built in the United States during World War II. It was a two-seat machine intended to demonstrate the feasibility of a twin-rotor system, and while it accomplished this, it also demonstrated a number of problems that prevented further development of this particular design.
