1. A helicopter, comprising:
- a lift module having a propulsion system and at least one rotor driven in rotation about a mast axis by the propulsion system;
a support module for supporting the helicopter when landed, the support module having at least three support members assembled in a radial array about the mast axis; and
a payload support system adapted to couple an external payload directly to the lift module;
wherein the payload support system bypasses the support module, such that the external payload is carried by the lift module during flight and no portion of the external payload is carried by the support module; and
wherein the payload support system comprises a rigid link pivotally attached to the lift module via the transmission.
