(OP)
The following web page describes a rotor hub concept, where the intent is to incorporate the advantage of an offset hinge into a teetering rotor. http://www.SynchroLite.com/1127.html
Constructive criticism, questions or comments will be much appreciated.

An interesting two-bladed helicopter was the Sud-Ouest Djinn. It had a rigid hub and 2-offset hinged blades. That was a small helicopter with a gyro-bar for addedd damping.

Thanks for the reply.
The blades should not have to be hinged to create a hub moment. Theoretically, an absolutely rigid rotor could create a hub moment. Yes, the Tie-bar does force the blades to flap (teeter) in unison, like the blades on a teetering rotor. I believe (hope) that the force vectors that are parallel to the mast and are located at the end of the offset arms, will apply a moment to the hub, just like a fully articulated rotor.
If this is incorrect, please advise.
