Heres mine. Anyway if I was you I would try to get a Tamiya off Ebay even an old kit for $200.00 and $50.00 for some HL electronics will be such a better tank.
I would think that about 60% ot this tanks have something wrong with them out of the box.

Unless they have changed them they are a tri-color with brown sand and almost a reddish purple like color. I wonder if they did not use some left over toy car paints on them.
