During the late thirties,the success of Juan de la Ciervas design in the series of rotorcraft-autogiros, attracted the attention of experts in Yugoslav aviation , who came to Great Britain to buy fighters bombers and other equipment.

They bought two of Cierva C.30A autogiros, early in 1938, but before that, two experienced Yugoslav officers, Captains Drago Brezovsek and Aksentije Panic, were sent to train on such a craft in "Autogiro Flying School" (London Air Park), Feltham, Middlesex. Their instructors were Stoker and Marsh.They completed flying in March of 1938 and got the "Pilots Certificate...for... all types of gyroplanes". A Panic had No.14021 license.In Yugoslav air force autogiros were intended to replace air balloonsin observers duties and the First Autogiro Group was formed,

  consisting of three escadrilles, each containing 6 to 8 autogiros. But, beside the two existing ones other aircraft's were of different types- obsolete biplanes, trainers and communication planes. So, until the outbreak of war, all rotorcraft force consisted of a couple of C.30A, occasionally used in smaller exercises for liaison and observing duties.

Most probably due to the approaching war, the whole attention of Air Force was directed to combat planes and rotorcrafts were postponed to reappear ten years later. Anyway, the presence of such flying machine in Yugoslav air force, in the very beginning of rotor planes development shows that the Yugoslav airmen correctly judged and evaluated their importance and future role.
