The LAK-17 is designed to meet the requirements of the utility category of JAR-22. It is a single-seat mid-wing sailplane of composite construction with a T-tail and flaps, it has a retractable single-wheel main landing gear and has airbrakes on the upper wing surface. The airfoil is a combination of the LAP92-130/15, at its roots, and the LAP-92-150/15, at its tips. The LAK-17 holds water ballast in tanks in the wing and fin. The LAK-17A was certified in November 1994 by the Lithuanian Civil Aviation Authority. A new variant with an improved wing was designated the LAK-17B. All variants have a 15.00 m (49.21 ft) wingspan but a wing with span increased to 18.00 m (59.06 ft) is available as an option; powered self-sustaining versions are also produced.
An optional front electric sustainer engine variant was developed for the LAK-17 by Slovenian engineers at LZ Design. It originally had a 0.9 metre propeller, and the latest versions have a 1.0 metre propeller in the nose driven by an electric motor.
