Iown 8 VS Tanks and not one of them has an issue except the type 90 which was my own clumsy fault! They look great, sound all the same, but operate very well. My T72 has the hard tracks upgrade and it drives perfectly in the garden. You might also want to get a Sherman with the linked tracks, fantastic model. Also the VS Tank website has a free VS Club which lets you order parts and accessories a very reasonable prices. VS Tanks are big funfor the $$$ IMO.
