The Kitty Hawk Models MiG-25 should be in stores shortly; meantime the excellent 1:48 scale F-35 Lightning II is available here now.
Single and two-seater versions can be built. Neatly-moulded cockpits provide food for detail freaks.
The MiG-25 radar used vacuum tubes, though that's not so primitive as it sounds, as the technology was more radiation-proof than transistors of the time, a big plus for the atomic-age Cold War era.
Gorgeous detailing in the wheel wells, and on the doors too. Ordnance looks convincing, too.
Camera ports and plenty of weathering apparent in this closeup pic (above) while low altitude shot (below) shows the somewhat ungainly lines of the two-seater.
