Overview
The HKS-1 was a German 19 19 m (62.3 ft) span high performance two seat sailplane, designed around 1950 to use recent advances in laminar flow airfoils. To avoid premature transition from laminar flow caused by surface interruptions, the HKS-1 dispensed with hinged ailerons, flaps and spoilers and replaced them with a flexible trailing edge. Two were built, setting several records.
