Knight Invader III is a super racecar that includes mini-construction projects, teaches the basic principles of electricity, gear mechanisms, and demonstrates three different modes of propulsion. This sleek super racer has it all and a little bit more. Knight Invader III can blow a fierce force of air to propel it off the starting line and challenges any contender to try to stay up when it is changed into direct motor drive. When on a mission, it can secretly change its transportation mode to solar power (sold separately). Plus, for the educationally minded guardians, this fireplug kit includes mini construction projects that teach the basic principles of electricity including experiments involving series and parallel circuits and solar energy (sold separately). No tools required for assembly.
