Based on an earlier design by Burt Rutan, only seven A500s were built between 2005 and 2008 when Adam Aircraft Industries went out of business. Numerous problems held back the program, the worst being excessive weight. A jet derivative was proposed but did not get off the drawing board.

The aircraft had flown into Palm Springs International Airport (KPSP) and then taxied the 1¼ miles thought the city streets to be exhibited at the AOPA Convention. It is displayed here at the parking lot in the corner of E Amado Road and N Calle Alvarado, north of the Convention Center.
