Smallest RC Cars?

DigiQ from Takara is infrared-controlled, has two independent rear wheels powered by two tiny motors, and comes with a pistol-style analog controller. Bit Char-G from Tomy (Tomica) is radio-controlled, single-motor rear wheel drive, front wheel steering, and comes with an awkward controller with forward/backward + left/right switches. You really need to see the video clips to appreciate how small and maneuverable these cars are. I personally like DigiQ more, because of its powerful motors and analog controls. On the other hand, Bit Char-G has an extensive line of hop-ups and accessories. DigiQ sells for $50-$80 and Bit Char-G for $30-$50."
