a housing including a control unit and an attachment mechanism for connection to the drone;
a motor within the housing for generating a rotational force at first speed;
a gear assembly within the housing connected to the motor for translating the first speed into a second speed lower than the first speed;
a reciprocating screw within the housing connected to the motor via the gear structure for rotation at the second speed;
a spool in direct rotational communication with the motor for rotation at the first speed;
a winch line with a first end and a second end; the first end connected to the spool for winding the winch line evenly around the spool as guided by the reciprocating screw; the second end extending from the housing and for connecting to a payload;
a hook assembly connected to the second end of the winch line, the hook assembly including a jaw for releasably carrying a parcel;
a solenoid pin in a slider for locking and releasing the hook assembly; and,
