Like several other glider designers of the early 1930s, Lajos Rotter was impressed by Alexander Lippisch's Wien of 1929 and his high performance, single seat Karakán bears its influence.

Both designs had, on each side, an airfoil-faired V-form strut from the lower fuselage to the outer ends of the centre section, the forward member of the V, connected to the main spar, was more substantial than the rear.

Lippisch had a used standard Göttingen airfoil whereas Rotter used one of his own, though both designers chose to merge into more symmetric profiles outboard.

The Wien and the Karakán had very similar vertical tails, with balanced rudders, large and rounded apart from a straight underside to avoid the ground, mounted on small, short fins.

Like most sailplanes of the time, both landed on a single skid, the Karakán's rather longer, with a small metal tailskid to protect the rear fuselage.
