You control the Nitro Flash! Put the sleek Nitro Flash together and make it go with your RC controller! Three channels lets up to three cars race at once. Build a tough 4x4 off-road style racecar, then take it into the pits and turn it into a high-speed dune buggy! Swap wheels with other Racers models to change how fast the Nitro Flash can go, and how well it handles the curves. You're on your way to the checkered flag! Includes all the pieces needed to build the Nitro Flash, controller, and extra set of two small wheels.
