Claim 12:
13. A method for monitoring conditions at a property using a drone, the method comprising:
generating control signals using circuitry positioned in an internal cavity of a drone that includes a housing that circumscribes the drone, and a plurality of ducts disposed in the housing, wherein the housing comprises:
the internal cavity positioned at a location intermediate two respective ducts of the plurality of ducts; and
a respective stator vane in each duct of the plurality of ducts, wherein the respective stator vane is secured in a corresponding duct by way of attachment to an inner wall of the corresponding duct;

using the control signals, operating each fan of a respective fan assembly installed in each duct of the plurality of ducts included at the drone, each duct of the plurality of ducts having a respective inlet that includes a rounded edge between an inner wall of the duct and a first continuous surface, each respective inlet of the plurality of ducts forms a merged air inlet that causes a reduction in a static pressure of air at the first continuous surface that flows into the merged air inlet;
generating a first air pressure at the first continuous surface of the drone that extends through a radial center of the housing by operating each fan causing the fans to distribute the first air pressure over an entire surface area of the first continuous surface that is substantially flat; and
generating a second air pressure at a second surface of the drone by operating each fan, wherein the second air pressure is higher than the first air pressure distributed over the first continuous surface that is substantially flat, and, wherein the respective inlet that includes a rounded edge between an inner wall of the respective duct and the first continuous surface.
