This one I wanted to present for a while now. An Unmanned Aerial Vehicle project in Czechoslovakian and Hungarian co-production.
In the Warsaw Pact this kinda research happened on entirely Soviet field and no publication was released by them. Similar secrecy goes for the opposing NATO and related powers. But these stuffs were around from the end of the '70s, first news of them came from the Arab-Israeli wars. Officers of the engineering corps were very much interested in it and the army also had the need to have them but while we had the electronic background we lacked in aeronautics. So a neighbour was approached - the only neighbour who was approachable, frankly -, Czechoslovakia, who judged they can complement us with their aviation experience (they even had a few radio controlled planes for target practice, which could fly only in visual range due lack of on-board devices), but the electronics R&D would be too much for them. The initiative started in the late '80s.

Pics: the first modifications of the Czechoslovak target drone. One notable thing is the 4 cylinder engine.
