This is a injection plastic and metal radio or remote-controlled car model.
As seen on TV (here in Japan)! This crazy little infra-red remote-controlled car can drive on walls! And on the undersides of tables! And on the ceiling (although not recommended by Takara Tomy)! The secret to its spider-like clinging abilities is a suction fan mounted in the body that literally keeps the car sucked down tight on any smooth surface you place it on. Yes, you do need a smooth surface, or the little guy can't cling to his full potential. Use the controller to drive forward, backward, right, left, and perform dynamic spins. The controller also acts as a battery recharger for the car. The controller itself requires six AA batteries; not included. Two Aero Spiders can be operated together, as long as their operating bands are different (A or B). This Aero Spider is finished in a cool gray, and operates on the B band. See the other Aero Spiders, linked below!
Check out the Aero Spider webpage, too! It's all in Japanese, but some clicking of the various icons should produce some interesting results!
