Claim 6:
7. The propeller assembly of claim 1, further comprising a hinge coupling the first magnet to the rotating assembly, the hinge:
pivoting the first magnet away from the second magnet in response to a centrifugal force generated by the rotating assembly rotating about the rotational axis so that the propeller has the angular velocity greater than the predetermined value, to a position wherein the first pole faces along a direction parallel to the rotational axis; and
holding the first magnet at a position wherein the first pole faces the second pole along the alignment direction so that the attractive magnetic interaction holds the propeller in the stowed configuration when the angular velocity is reduced below the predetermined value.
