Thank you all for so hot welcome!
Yeah, it was more then twenty interactions before I reached final mechanical structure. I realised to late that I picked wrong scale for the tank because other mocks are in 1.5 time bigger. Of course my goal is to make it as much closer to original tank as it can be.
I can sure you all, it is really one motor used to animate body, and one more for gun. As well it will be 3 more motors: 2 of them will be used to rotate wheals, and the rest to rotate gun.
And of course, I will definitely share photos and explanation of all mechanical parts when it will be established.
