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."
Personally, I'd rather have RC helicopters. Yes, I know their batteries wouldn't last long... but in an office environment, tiny cars aren't going to get very far, given the amount of clutter which would obstruct them. Helicopters, on the other hand, could fly over cubicle walls to attack people...

There is a review of the Bit Char-G here.
It includes some better images.
