The Hopfner HS-8/29 was a utility aircraft built in Austria in the late 1920s based on the Hopfner HS-5/28. It used a modernised version of its predecessor's airframe, being a conventional, parasol-wing monoplane with seating for two occupants in tandem, open cockpits. The landing gear was of fixed, tailskid type with divided main units. The first prototype used the same Walter NZ 85 engine that the later HS-5/28s had used, but this was followed by 14 production examples with Siemens engines, and a single prototype with a de Havilland Gipsy III.
