Roar. The King of the Jungle is here. Use this guy to terrify all of your other Tamiya Mechanical Animals! Tiger's body parts have been molded with yellow semi-transparent plastic, giving a view of all the internal mechanisms. Assembly is very simple with use of screws and snap-lock parts. Power from the electric motor is transferred to the legs via crank plates to make the tiger walk. 2 possible gear ratios coupled with 4 different strides let you choose 8 different speeds. A reverse switch also allows backward movement. A screwdriver for the assembly is provided. Requires one AAA battery (sold separately). Continuous running time with Alkaline battery, 2 hours. These Tamiya animal kits are fun to build--collect them all!
