[1] The Lapke was a pod-and-boom glider with a high wing mounted over the front end of the boom and braced with inverted-V struts from the lower fuselage to the spar.

The beam carried the single seat in an open cockpit, locally ply-covered and with a removable ply cover fitted with a windshield, around the pilot.

From the aft of the beam a metal tube strut reached upwards and rearwards to support the boom that formed the rear fuselage.

The end of the fuselage beam also mounted an exposed monowheel, assisted by a short, rubber sprung landing skid ahead of it.

The tailboom was a horizontal, rectangular section, wooden, ply-covered structure mounted under the centre of the wing spar and braced with wires from mid-span to the tail as well as the steel tube.

A series of sixty-five slightly modified R-16bs followed over 1952-3 and these became the standard Hungarian single-seat trainer; once launching was mastered, pilots continued in the Lepke to their C certificates.
