This is the Zvezda MiG-21bis, with Kuivalainen etched details, Eduard canopy masks, a Master pitot probe, Armory wheels, and Balkan Models Croatian MiG-21 decals. The Kuivalainen details (produced by Eduard) were great and made a significant and rapid improvement to the cockpit. According to the Balkan Models instruction sheet, Number 102 “Avenger of Dubrovnik” is the ex-Yugoslav Air Force number 17235, in which Capt Ivica Ivandic defected from Uzice to Split on 15 May 1992. After a struggle building a kopro MiG-21UM, the Zvezda bis was a really nice kit and a treat to build.
