Geek Toys: MicroCar Smackdown Pocket-sized radio controlled cars, available for $20 or less with controller -- and infinitely customizable -- are now taking the New World by storm. These tiny cars, which measure about 2 ½" long, have been a favorite of salarymen and schoolboys in Japan and throughout Asia. Imports have been available in the US for a while; some using illegal radio frequencies. In fact, Hobbico has been selling a US-friendly version of Tomy's Bit Char-G, the R/C MicroSizers, since the end of August.
