This is a fun little BB-shooting tank kit that can be operated by remote control! The gearbox and motor assembly comes pre-assembled, but you have to put together everything else. This is "remote-controlled" kit, not "radio-controlled," and the hand-held controller unit is connected to the tank by wires that cannot be disconnected. Each control stick controls one track, so the tank can move forward, backward, turn right and left, and pivot right or left. The turret is fixed, but can fire the harmless plastic BBs at a rate of 140 rounds per minute. Includes self-adhesive stickers for the markings. Instructions are in Japanese, but a well-illustrated and easy to follow.
