Hopfner HR.1434 / HR.14/34
 
Hopfner-1434-01
 
After the development of the transport high-level plan HV.12 / 34, designer Lampich started the design of the low-wing transport aircraft, designated Hopfner HR.14/34 (HR.1434) Werk.Nr 33. Despite not some similarity, it was a completely unique project. The only example of the aircraft was built by Flugzeugbau Hopfner GmbH at the Aspern Vienna airfield.
 
The retractable undercarriage was later modified as fixed.
 
The first flight of the aircraft prototype (registration number OE-DBL, D-OBDL later) took place on March 24, 1936. The aircraft was used (mainly for advertising purposes) until the spring of 1937.
