The self launching Antares 20E is the flagship of the Antares family of sailplanes.

Using lightweight high performance batteries a brushless 42 kW external rotor electric motor, new power electronics and a large slowly rotating propeller, a completely new propulsion system has been developed exclusively for the Antares 20E.

The results are convincing: The Antares 20E combines a high climb rate (approx. 4.4 m/s / 866 ft/min during takeoff) with a very high attainable climb altitude (approximately 3000 m / 9850 ft in calm air) and very low noise emission.

The aerodynamic design of the Antares 20E is the result of an ambitious research project, and it combines very good climbing characteristics, excellent glide ratios even at high speeds and optimum thermalling performance with overall very pleasant handling characteristics.

This particular aircraft is modeled after the Antares prototype, D-KBLF, which is operated by Lange Flugzeugbau GmbH.
