A Set of Ducted Fans powering a Tamiya Robotic Chassis

We have used a pair of R/C ducted fans with TX/RX/ESC taken from a Super B2 Spirit from Interactive Toy Concepts and made them to fit a Tamiya Robotic Chassis running on caster balls. Controlling the Drifting and powering by jet-like ducted fans. Awesome robotic chassis kit project - perfect DIY project for youth.
