Thank you for hearty welcomes, guys!
As for tank clubs in Russia, there's none. Unfortunately...
There are some people who have Alex's big tanks (1/8, 1/6). But the number of these tanks sold in Russia is close to 10 pcs. The rest go abroad.
Tamiya tanks are cheaper in comparison to Alex's but still too expensive for people. I am lucky to have one. I hope, the quantity of Tamiyas sold in Russia is good enough, but I have no info about their owners. Tried to find some - no use. I am planning to make a website to attract people to this hobby.
WSN and Hen Long are sold well here. These tanks are toys, so most people treat them as toys. I don't think their owners will try to group.
Kubinka is a good place to visit. I hope to go there this summer with my son. Just need time, I have lots of work at the moment.
If you need any photo of a tank, I can make it for you.
