Multicopter

A multicopter foldable between a first, folded stowed state and a second, expanded operational state, the multicopter comprising:

• a hub configured to receive one or more payloads and a battery,
• two or more flight arms that extend substantially horizontally when in the operational state, each flight arm of the two or more flight arms comprising:
• (i) a main arm, each main arm extending from the hub at a main arm pivoting connection, and (ii) two cross arms extending from the main arm at a cross arm pivoting connection,
• the main arm pivoting connection allowing each of the main arms to pivot towards the other main arm to a stowed state wherein each of the main arms are substantially parallel to the other main arm(s) in a vertical axis, the cross arm pivoting connection adapted to allow each of the cross arms to rotate towards the main arm to a stowed state wherein each of the cross arms are substantially parallel to the other cross arms,
• wherein the multicopter comprises landing gear that is substantially parallel to the flight arm when in a stowed state and an operational stowed state and either
• i) extends from an intersection region between the main arm and cross arms of the two or more flight arms via a hingeable connection;
• or
• ii) extends pivotably from the hub, wherein the landing gear is adapted to fold against the main arm, such that the landing gear is substantially parallel to the flight arm when in a stowed state and an operational stowed state, and
• wherein the multicopter further comprises a notional polyhedron defined by the flight arms when in the stowed state, the notional polyhedron defines a volume to contain, when present, the one or more payloads and a fuselage, wherein each flight arm of the two or more flight arms and the landing gear is positioned parallel to an elongate axis of the hub in the first, folded stowed state, and
• wherein, in the first, folded stowed state, elongate axes of the main arms, the cross arms, and the landing gear are adjacently aligned and substantially parallel to each other and to an elongate axis of the hub.
