In order to eliminate the 18-degree offset the rotorhead would have to be redesigned and the cone hinges eliminated. This would allow the rotorhead on the Robinson to be like that of the Bell. By eliminating the cone hinges the pitch horn could be made into a 90-degree pitch horn as opposed to one of 72-degrees.
In doing this another major problem would develop and that is severe blade bending and no way of minimizing the flapping loads resulting in blade failure. For the short period that the rotor would stay intact the Robinson would behave like a Bell and It could be rigged like a Bell.
