As the larger unlimited displacement engines became common place, designers predictably proved the rule makers wrong, and the already 2-meter long "yard dart" designs morphed into larger volume fuselages (like the EMC2). The larger fuselages more easily completed rolling maneuvers and the slowly increasing amount of integrated loop/roll maneuvers found in the FAI schedules. The once massive fuselage volume of the EMC2 rapidly became average amid the designs of the day including the Angels Shadow, Hydeout, Smaragd, and Synergy. While the FAI schedules continued to challenge airplane designers with increasingly difficult combinations of integrated loop/roll maneuvers, rolling circles, and snap roll/roll combinations, the biggest change to the Pattern landscape came from a new technological development.
