Thank you. So it's fine until the gears or differential or whatever keeps the rotors in sync misses a couple of teeth, they chop each other to bits, and you just drop out of the sky?

Pretty much, but then again, the kind of catastrophic gearbox failure you describe wouldn't be a good thing in any type of helicopter...

Contra-rotating blades one at a different angle and pitch.

The axes of the rotors are arranged symmetrically on top of the fuselage in terms of angle and pitch, just intermeshing I think.

Here's a picture of one in flight.

Id never go up in one of those, looks like an airfix kit and a lot of trust goes into that engineering!

Doesn't matter if its a conventional main/tail, co axial, notar, filthy boeing death banana or any other type they are all trying to kill you the moment you relax or even think about trusting them
