Lange Aviation finally launched the sustainer for their race plane Antares 18. It seems to be a pretty fine machine indeed!
On Friday 30.11.2012, after a take-off run of approximately 200 m (660 ft), Axel Lange performed an unproblematic climb to the cloud-base at an altitude of 1800 m (5900 ft) MSL. The average climb rate from the airfield (340 m / 1115 ft MSL) to 1800 m MSL was exactly 2,0 m/s (395 ft/min).
Due to the good motorisation it was possible to get airborne with a self-launch.
