Zmaj R-1
The Zmaj R-1 was a twin-engine bomber produced by the Yugoslav aircraft manufacturer Zmaj in Zemun . The machine was intended for use as a bomber, reconnaissance aircraft and destroyer . In 1940 a prototype was built; the Second World War , which also affected Yugoslavia in 1941, prevented further development.
The R-1 was powered by two 14-cylinder double radial engines Hispano-Suiza 14 AB with 670 hp each and was designed in a mixed construction; the machine reached a top speed of 450 km / h at an altitude of 4,000 meters.
