 The control surfaces are made of welded steel tube, covered with fabric and the fixed V-strutted landing gear was built up from high strength steel tube enabling the SIM-VIII to handle rough landing strips.Three SIM-VIIIs were produced by Rogožarski 1931, owned by the Yugoslav Aerocub at Belgrade, (registered YU-PBC, YU-PBD and YU-PCI) which used them for propaganda flights and training sport pilots.The first of the listed aircraft flew until 1937, when it was withdrawn from use and the other two have no recorded history.
