As of July 2005, E.S.Aero has relocated to Oceano Airport (L52), which is 15 miles south of San Luis Obispo, CA.  The company is currently operating out of two 1,000 square-foot hangars which have contain converted computing and office space, a fully capable audio and video teleconference room, and dual machining and assembly workshop areas.  The most recent expansion was into a third 2,000 square-foot hangar used for large-scale indoor testing.  Being located on an airport has brought many advantages to the company, including easy access to air transportation, high public visibility, and room for future facility expansion.  Most importantly, calling Oceano Airport home has given E.S.Aero ample space for prototype flight testing, eliminating the need to travel long distances for engineering tests.
