Construction in MSrE's workshop began in 1944 but the partially built aircraft was destroyed in the siege of Budapest the following year.

Its two-piece, mid-set wing was built around single main spars and in plan had rectangular centre sections out to about one third of the span and trapezoidal outer panels with forward swept trailing edges.

The outer panels were fabric-covered and carried split, differential ailerons which reached out to the tips and were interconnected with the flaps.

Göppingen type spoilers, mounted behind the spar at the ends of the inner sections, opened both above and below the wing.

[5] The Super Fergeteg's wing had had very slightly forward swept leading edges, one piece ailerons and no flaps.

All variants had similar horizontal tails, trapezoidal in plan out to rounded tips and with elevators requiring only small cut-outs for rudder movement because of their forward position.
