1/24 Scale FOV remote controlled tank, infrared combat, Panzer IV
 

Unimax or Forces Of Valor 1/24 scale remote controlled tank. These are no longer available the company has gone out of business many years ago. Has Battle Beam infrared combat function where you can choose teams avoiding fratricide (unlike the Tamiya system). It uses different infrared signals for each team so you score against an enemy team and not tanks on your team. All you need are batteries to start playing (and another FOV tank). Nine volt for the transmitter and AA for the tank. I don't believe these are compatible with the Waltersons tanks (they bought the line after FOV went under).
