This is a Ready to Run Expert Built R/C car of the Lexus ENEOS SUSTINA RC. The product is a result of Tamiya"s expert builders assembling the kit at Tamiya"s factory. Each kit is hand built, painted and finished so the user may enjoy Radio Control action right out of the box. All you need is 2-AA batteries for the controller and your choice of battery pack and charger (sold separately). The Lexus ENEOS SUSTINA RC body is mounted on Tamiya"s entry level TT-01ES full-time 4WD chassis platform. The XBS SPORT chassis is Tamiya"s basic entry level platform, but can be outfitted with any of the Option Parts available for the standard TT-01 E chassis. The RC model is also outfitted with Tamiya"s 2.4 GHz FineSpec radio system for interference free operation.
