I saw one at a toy store(note: I said,"Toy Store")
It looked very bad,even worse than the 1/16 Abrams I bought on e-bay.
This is one of the most "toyish" tanks I have seen.......yes it is big,but at what cost

I got the 21st century 1/9 torn apart for mods now( its cheap too,but not as bad as the 1/12 one)
Can you return it?
tell them it "smoke checked bad",get a refund and buy something else.........2 cents
