[clarification needed][1] The Eta made its first flight on July 31, 2000 in Cochstedt, Germany, reaching a height of 2 m (7 ft).

The second prototype was extensively damaged in 2003 during the spin tests required for the type certification but both pilots parachuted to safety.

The private development of the Concordia sailplane promises a further elevation of the max lift-to-drag ratio to slightly over 75 at 137 km/h (85 mph; 74 kn).

[2] An Eta participated in a World Championship for the first time in 2003 at Leszno.
