Modified versions of the Habicht, dubbed the Stummel-Habicht ("Stumpy Hawk") were used to train pilots to land the Messerschmitt Me 163 rocket-powered fighter, and allegedly for training Hitler Youth pilots for flying the Heinkel He 162Spatz jet fighter. The Me 163 was designed to use its entire load of fuel to reach combat altitude and then return to the ground as a glider, with the He 162A having a short, 30-minute flight envelope with a similarly fast landing speed. However, the landing speed of around 200 km/h (125 mph) posed a special challenge for pilots. Trainees therefore began on a Stummel-Habicht on which the original Habicht's 13.6-metre (44 ft 7 in) gull wings had been replaced with straight wings of 8-metre (26 ft 3 in) span, and then progressed to another version with a 6-metre (19 ft 8 in) span.
Few Habichts survived the Second World War. There is one machine, flown by famous French aerobatic pilot Marcel Doret, in the Musée de l'Air et de l'Espace in Paris. Another, with the registration D-8002, flew in Southern Germany until it was destroyed by the collapse of the hangar where it was stored. Apart from these genuine examples, Türk Hava Kurumu manufactured six reverse-engineered copies of the Habicht as the THK-3 in 1945-46.
After a long and patient research to recover the design documentation, Josef Kurz and other members of the Oldtimer Segelflugclub Wasserkuppe built an all-new Habicht. After an extended exhibition career, this exemplar registered also as D-8002 flies from the Wasserkuppe club's airfield.
Another airworthy Habicht was built by the Zahn family and first flew in 2001. Since then, at the hands of pilot Christoph Zahn, it has provided aerobatics demonstrations at numerous air shows.
