Production was transferred to Vazduhoplovno Tehnicki Centar (VTC) at Vršac in Yugoslavia where an additional 63 were built.

Haro Wodl won the 1968 World Gliding Championships in the open class, flying a Cirrus.

The resultant Cirrus has mid-set cantilever wings with a span of 17.74 metres, and a conventional low-set cruciform tailplane.

For glidepath control, there are effective top-and-bottom air brakes and a substantial drag chute built into the bottom of the rudder.

Holighaus chose a rather thick flapless Wortmann airfoil (FX 66-196/161) which had low drag (for the time) and very gentle stall characteristics.
