SET 10

The SET 10 (unrelated to the SET X design of the same year) was a trainer aircraft produced in Romania in prototype form in the early 1930s. It was a conventional, single-bay biplane with staggered wings braced with N-struts. It was equipped with fixed tailskid undercarriage, and seated the pilot and instructor in tandem, open cockpits. Intended for Romania's aeroclubs and Air Force, no production ensued.
