Various implementations include a rotor control device including a shaft extending along a rotational axis, a hub, first and second pitch control components, and a swashplate. The hub has a hub axis and is hingedly coupled to the shaft such that the hub axis is perpendicular to the rotational axis and stationary relative to the shaft. The hub is hingable about the hub axis relative to the rotational axis. The first pitch control component is coupled to the hub. The swashplate has the second pitch control component hingedly engaging the first pitch control component. The swashplate is movable along a swashplate plane transverse to the rotational axis. The shaft is rotatable about the rotational axis relative to the swashplate. Movement of the swashplate along the swashplate plane relative to the rotational axis causes the hub to periodically hinge about the hinge axis as the hub rotates about the rotational axis.

Embodiments described herein relate to a vertical take-off and landing aircraft, specifically an electric or hybrid electric aircraft having a plurality of ducted fans. The aircraft includes a plurality of axially oriented fans, laterally oriented fans, forward air intakes, side exit ports, rear exhaust ports, plenum air chamber and annular inlet. The aircraft achieves flight by capturing air in the intakes and diverting the air through the axially oriented fans or the laterally oriented fans through the channels selectively.

A magnetic de-rotation system includes an inner ring which supports an eddy current ring and at least one inner ring magnet and an outer ring which supports at least one outer ring magnet, attraction between the at least one inner ring magnet and the at least one outer ring magnet produces a stable rotational position for a fairing.
