The Hopfner HV-6/28 was a small airliner built in Austria in the late 1920s for Swiss use. Unrelated to Hopfner's other airliners of the period, the HV-6/28 was a conventional, high-wing, strut-braced monoplane with a fully enclosed cabin. The main units of the fixed tailskid undercarriage were divided. The single example built was flown by Aero St. Gallen between 1929 and 1931, and then scrapped.
