Albastar 13,5m FES is a single-seat motor glider with 13.5 m wingspan designed for FAI 13.5 m class which took its maiden flight in April 2013.
The glider has 23 kW front electric sustainer (FES) positioned in the nose which in combination with low takeoff weight is powerful enough to be used for self-launch.
However, the glider also incorporates a tow hook mounted in the center of gravity for the classic aerotow.
First prototype AS-18M is powered by two-stroke internal combustion engine with the propeller mast mounted behind the cockpit.
[4] It has a self-launching capability and unlike other similar gliders, it has the unique feature of starting the engine before the propeller mast is extended, therefore practically eliminating the period of increased drag before the engine is started.
