Here's Tamiya's fantastic RC M4A3 Sherman kit paired with their RC Battle System...an infra-red shoot-and-hit system that lets two or more tanks have at it in a realistic battle simulation! The RC system allows for a full range of movement plus turret rotation and main gun elevation and depression. The movement is realistically slow, accurately conveying the weight of this massive iron beast! All movement is accompanied by realistic sound, including the firing of the main cannon, which is accompanied by a realistic rocking of the tank (and flashing light in the muzzle!). The RC Battle System registers hits taken from enemy tanks, and when hit, stops the tank's movement and droops the main gun...a sure sign of a knock-out! Requires four AAA batteries and one 9-volt battery, all sold separately.
