In preparation of the glider had also participated test pilot Jacek Marszałek. In connection with bankruptcy of Zakłady szybowcowe, there were produced only four copies. One went to Wojciech Kos of the Aero Club Bielsko-Biala. The second in 2000, was issued by the Polish Aero Club for sale. The other two went to the United States. When Zakłady Szybowce went bunkrapt, MSc. Bogumil Beres bought from the trustee the rights to produce Diana and founded his own company. The newly formed company started the implementation of the production of the glider.
