Wackywheels, I have a post about that model that you can view, its a few weeks back. Search this forum, you will find it. You asked about problems? That tank is nothing but trouble, turrent controls smoked out in a month, turrent motor in less than two. This tank wouldnt work out of the box, first I had to repair some things, then these other problems surfaced. Since I "tinker" with stuff, I've been working with this thing, but if youre not a "tinkerer" send it back. Its a load of CRAP! I think they get $75.00 bucks plus shipping, for those things, they aint worth the shipping if they gave it to you free. Beware they are all over Ebay, along with the scam artist that sell them. So if anyone else reads this also, these things are worse than anything you have ever seen. This thing should have come with a soldering iron and a roll of solder. I hate to sound so negative but others have had trouble also, maybe they will respond too.
