A disclosed vertical lift flying craft includes a lift unit that, during
operation, develops a force including an upward component. A payload unit
suspends from the lift unit. The payload unit suspends from the lift unit
in such a way as to impart lateral stability while remaining capable of
horizontal flight, without incurring the adverse effects of a downward
pitching moment. In addition to a lift unit and a payload unit, the
vertical lift flying craft includes a pair of bearings and a suspension
structure, which cooperate to suspend the payload unit from the lift
unit. Other systems and methods are also disclosed.
