Abstract
A heavy-lift UAV frame includes a central frame portion having a symmetrical shape and forming a pocket area for receiving an avionics package. Top and bottom plates are secured to the central frame portion and include four corner members that extend diagonally outward therefrom. A plurality of boom arms are pivotally connected to the corner members and transition between an extended position for flight and a retracted position for storage and transport. Each boom arm includes a complementary dimension to one side of the central frame portion and is arranged parallel thereto when in the retracted position.
