Abstract: In some embodiments, an apparatus includes a fuselage of an unmanned aircraft that includes a first section removably coupled to a second section, and a third section removably coupled to the second section such that the second section is disposed between the first section and the third section in a vertical direction. The first section includes a first rotor and a second rotor disposed at a non-zero spaced distance in the vertical direction from each other. The first rotor and the second rotor share a common and aligned rotational axis defined along a longitudinal centerline of the fuselage defined in the vertical direction. The second section is configured to contain a selected payload, and the third section includes a control system. A plurality of legs are coupled to the third section and serve as landing gear for the unmanned aircraft.
