Having used most of the plastic model kits of USSR/Russian warplanes for the Iraqi airforce I'm using Die-cast models for the modern Russian Airforce. Most will be Altaya both from Aircraft or Helicopter current collection.
These models are just great. You just need to glue a few parts and they are ready to fly. Of course you may not get the right camouflage for a determined conflict but the Russian army I'm building also covers a wide period of time of some 20 years (1996-2016, and when next January comes a new year starts).
