EADS Inovations unveiled 4 engine electric-powered CriCri Aircraft. This small aircraft used composite materials instead of metal to reduce overall weight and make room for the high-energy-density lithium batteries. Those cells provide power to four brushless electric motors – two mounted back-to-back on nose pods on each side - with counter-rotating propellers.
This EADS Cricri has performance: 30 minutes of cruise flight at 110 km/h (68 mph); 15 minutes of full aerobatics at up to 250 km/h (155 mph); and a climb rate of approximately 5.3 m/sec (1,020 fpm). (eaa.org)
