<p>Propellers, propeller stabilizers, and propeller related vehicles are provided in accordance with the present invention. A helicopter (10) with motor mechanism and drive shaft (46) for powering the main propeller (20) is described. The helicopter also includes a stabilizing mechanism (50) between the drive shaft (46) and the propeller (20). The centrifugal force created by the ratation of the propeller will tend to pivot the propeller back to a horizontal position. Many configurations of the above may be used.</p> |
