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.
In 1934 the SET 10 was advertised for club trainer use with a 108kW (145hp)Walter Mars I nine-cylinder radial engine. This gave it a top speed of 177km/h (110mph; 96kn).
