SET 7

Manufacturer: SET
Designed by: Grigore Zamfirescu
First flight: 1931
Number built: 123

The SET 7 was a military trainer and reconnaissance aircraft produced in Romania in the mid 1930s. As originally designed, it was a conventional single-bay biplane with slightly staggered wings. The undercarriage was of fixed tailskid type and the pilot and instructor or observer sat in tandem, open cockpits. Power was supplied by an Armstrong Siddeley Jaguar 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-Rhx´ne 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.
