SET 7

The SET 7 was a military trainer and reconnaissance aircraft that was produced in Romania in the mid-1930s. It was originally designed as a conventional single-bay biplane, with slightly staggered wings, a standard undercarriage with fixed tailskid, and a tandem open-cockpit arrangement for the pilot and instructor or observer. Power was supplied by an Armstrong Siddeley Jaguar radial engine, and from the outset the aircraft was equipped for wireless and photographic reconnaissance duties.

An armed version followed in 1934, adding a trainable machine gun for the observer and a fixed machine gun for the pilot. This version, the 7K, was powered by a neatly cowled Gnome-Rhône 7Ksd engine, and the 7KB (fitted with bomb racks) and 7KD were specialised subtypes that followed it. A floatplane version was produced as the 7H.
