An all-metal flush riveted sailplane with fabric covered control surfaces, the Blanik is stressed for aerobatics and has held many two-seat records. It is equipped with DFS type airbrakes and Fowler-type flaps. The main wheel has an oleo strut shock absorber and is partially retractable.

The Super Blaník is an improved version of the original LET L-13 Blanik. To save weight, the new wings were made without flaps, which were rarely used. LET also moved the tailplane to the top of the vertical stabilizer for better protection in case of outlanding. It has a new instrument suite and a new two-piece canopy (with different framing from that on the original L-13) to improve vision.

It is often used for advanced training. The Duo Discus replaced the Janus as Schempp Hirth's high performance two seater trainer. Although it shares its name with the highly successful Standard Class Discus, any resemblance is only superficial. It first flew in 1993 and is still in production at the factory in Orlican in the Czech Republic. It has a 20 meter four piece wing that is slightly swept forward so that the rear pilot is close to the center of gravity. Its best glide ratio was measured as 45:1

It is often used for recreational soaring. The G 103 C Twin III is a development of the Twin II with a new ‘Discus’ plan wing of slightly increased span and modified airfoil section. The cockpit has detailed improvements including better ventilation, relocated airbrake levers to give better purchase, and canopies restrained by gas-filled struts. The unpowered sailplane is cleared for aerobatics similar to the Twin II Acro. Its best glide ratio was measured as 36:1
