Although this method significantly reduced the cost and weight of the glider, until then this design had only been used in military aircraft, including the Bachem Ba 349 Natter and the Focke-Wulf Ta 154.
The design also included a hinged skid with suspension and shock absorbers and a spring-loaded spur as landing gear.
To solve this problem, they replaced the balsa wood in the wings of the glider with fiberglass, due to it being lighter and cheaper.
Several other design changes were made, including the replacement of the landing gear against a wheel, unconventional support of the control rods, and a number of structural optimizations.
After another failed test flight in June, Hütter and Hänle worked on fixing the problems with the glider's airbrakes.
