Hello everybody!
Since Chernobyl is not more than 1000 km from where I'm posting now, I thought I'll write you this post and if anybody starts building, maybe I could be helpful with some facts or reference.
So, most of the choppers seen in the fotos from the first link are Mi-6 heavy lifters. The wings are a russian invention allowing the helicopter to be more economical on long haul, as the wings in theory created lift while the chopper was flying with maximum speed. Not all Mi-6 had them fitted, and they were easily removable.
As for the trucks, ZiL-131 and URAL 6 by 6's would be the most common. I always found the russian fire engines interesting, but that would be a lot of scratchbuilding... Another very common truck is the ZiL-137, for some reason it almost always has blue cab - no kit of this machine I know of, unfortunately. There are also the UAZ jeeps and microbuses, the other type of microbus is called LuAZ - also not kitted, as far as I know. You can also see the BRDM - 2 armored scout (Dragon once made those) and also the ATS amphibians. The cool tracked engineering vehicle is called BAT. I also caught a glimpse of a turretless BTR-70 armored transport.
I wonder what's going to happen with this group build, If you have any questions maybe I can answer them, so good luck and have a nice day
