These are the remote controlled miniature racing cars that require only 10 minutes of charging between races. Each car's built-in lithium-ion battery recharges via the remote, providing up to seven minutes of operation, ideal for round-robin racing tournaments that last five minutes per round. Reaching 200+ mph scale speed, each 2 3/4" long car responds nimbly to left/right turn and forward/reverse commands from the radio remote up to 30' away, providing quick negotiation of impromptu race courses defined by eight included 1" high road cones. Each car operates on a separate radio frequency, allowing multiple cars to race at the same time. With working LED-powered headlights. Cars, remotes, and cone sets store inside 16 oz. "cans." Requires four AA batteries. 5" H x 2 3/4" Diam. (8 oz.) Set of Two.
