No radio or servos. You must provide your own R/C equipment (minimum two-channel).
No batteries or recharger.
No sound unit or turret rotation/barrel elevation hardware.
With this kit, if you provide your own two-channel radio equipment and batteries, you can enjoy standard tank motion, identical to the full kit (it does include the DMD motion control unit), but there is no sound, and no turret control. Add the Multi-Function Kit shown below to add turret control and sound action separately.
