a set of vertical lift rotors rotatably mounted to the body;
a corresponding set of electric motors mounted to the body and coupled to the set of vertical lift rotors;
a set of rechargeable battery modules mounted to the body and configured to electrically couple to the set of electric motors;
a plurality of photodetectors; and
a flight control system, comprising a precision landing receiver and a flight controller, the system configured to recognize a pulse sequence received by the plurality of photodetectors and distinguish the pulse sequence from ambient illumination;
