Well, I checked out what you were refering to and it is a little confusing. [] On the main tank page of their site, the link for the Tiger 1 smoke and sound goes to the link that you posted, but it does not say smoke and sound in the description. Usually, that is the big selling point, so I would wait and talk to a person at the shop if I were you.

I would not count on the tank coming with the metal gears or 8500 motors.....that sounds like an upgrade that you would probably have to add yourself. There are some of the HL tanks on Ebay with metal upgrades in the box, but I think that even then you have to install them yourself, in most cases.

Go to the shop and ask for exactly what you want and see what they can do for you, I guess.

Good Luck!
