Lange Aviation Antares 21E Self-Launch Electric Glider


The Antares 21 Electro is a single seat high performance self launch glider with 21.5 meter wing span. The 42 kW (57 hp) electrical motor powers a retractable propeller which rotates quite slowly, quietly and with very low vibration. With the standard battery the Antares 21 E can climb to 3500 meters with a climb rate of up to 4.4 m/s (866 ft/min). The best glide ratio (L/D) is 57.5.

This aircraft was developed in cooperation with the manufacturer Lange Aviation.
