Does the bet cover 1-bladed tail rotors? I believe the Hiller Hornet had one, but its main rotor was conventional.

Does it have to be a manned aircraft? http://www.youtube.com/watch?v=UY38uho9ZdE&feature=player_embedded

Bell built an experimental helicopter with one MR blade, the other side had a large counter weight. It was a modified Bell 47.
