Art Hughes paints an artistic display of 3-D flight with his new Miniature Aircraft Whiplash helicopter during the 2011 IRCHA Jamboree. The model is controlled by the Futaba fly-by-wire CGY 750 flybarless rotor head system. He says that the advanced technologies in the machine and electronics allow him to push the flight envelope to radical new levels. More than 900 enthusiastic helicopter pilots traveled worldwide to see pilots such as Art fly at the AMA National Flying Site in Muncie, Indiana. The annual IRCHA Jamboree is truly a helicopter pilot’s Woodstock.
