The fuselages of both designs became slender rearwards, the Wien's more than the Karakán; sections through the latter's fuselage were more biconvex or almond shaped than the Wien's oval, making it 30 mm (1.2 in) narrower. The Wien and the Karakán had very similar vertical tails, with

A second Karakán was built in the workshops of the Aviation Section of the Hungarian Defence Association (MOVERO), flying on 29 April 1935. Between them they set a series of Hungarian national gliding records and Rotter used it to become the first Hungarian to gain a 225:
