The SIM-VIII was designed by Sima Milutinović at the end of 1930, with a desire to contribute to the development of aviation in Yugoslavia.
The SIM-VIII was a parasol winged monoplane powered by an 82 kW (110 hp) Siemens-Halske Sh 14 engine driving a wooden 2-bladed propeller, seating two crew members in tandem open cockpits.
[1] Three SIM-VIIIs were produced by Rogožarski 1931, owned by the Yugoslav Aerocub at Belgrade, (registered YU-PBC, YU-PBD and YU-PCI)[2] which used them for propaganda flights and training sport pilots.
The two aircraft built in the Ikarus factory at Zemun in 1933 were not placed on the civil registry and are most likely to have been produced for the Yugoslav Royal Air Force.
Accolades awarded to the SIM-VIII include 1st place at the 1932 International Air Rally (Rundflug), held from 19 July 1932 at Warsaw.
