Tamiya makes some of the finest R/C models around, detailing & realism are in most of their models. This Tamiya tank currently sports the original Blackfoot body, until a suitable replacement can be found. Powered by a 12 volt gel cel battery, using an identical motor that I built for the Bruiser, this full metal tread drive tank is unstoppable. Weighing in at 12 lbs. this tank is capable of pulling a sled to full pull with over 50 lbs. due the the contact area of the tread. It also had a 250 amp speed controller, w/reverse, and with the tank body cover on, a moving gun turret, and radar dish.
Heres a shot with the truck body on, looking like one of those monster tank trucks.
Here you can see some of the interior workings. There is a limited slip clutch that allows for turns in forward or reverse.
