The LAK-20 is a Lithuanian Open Class two-seat sailplane produced by Sportinė Aviacija.

Design and development

The LAK-20 is an Open Class double seat sailplane with a wingspan of 23-metres or 26-metres. Made out of modern composite materials, it features a T-tail and retractable landing gear. The wings are slightly swept forward and interchangeable outer wing panels are provided to enable it to fly with a wingspan of either 23 metres or 26 metres. The glider is available as the self-sustaining LAK-20T variant or the self-launching LAK-20M variant, both equipped with an engine. The engines used are two-stroke two-cylinder retractable engines from engine manufacturer SOLO.
