This is a injection plastic and metal radio or remote-controlled car model.
Kyosho's Mini-Z 'readysets' come complete with car and controller -- you need only to insert the batteries (not included), and go! Comes with a wheel-type PERFEX 2-channel radio, 4 different size pinion gears, 3 triangle-type and 3 dish-type hurdles. Kyosho's superb engineering allows for overall tight, realistic control. The car runs for about an hour on regular dry-cell batteries. Requires 4-AAA batteries and 8-AA batteries (not included).
