The Lampisch LS-16 was a Hungarian training glider of mixed construction. It was flown but not granted a Certificate of Airworthiness.

Design and development

In 1939 Árpád Lampich designed a single-seat club trainer constructed from wood, steel sheet and steel tubes. Its wing, which was mounted on top of the fuselage, was rectangular in plan out to angled, blunted tips and built around a wooden I-beam
