OWI’s newest model of solar racing features not one, but two forms of power. The Solar/Battery Top Fuel Dragster, which gets its namesake from its long powerful dragster like frame (8.25″x3.25″x 3″), will be a fan favorite for years to come. Kids enjoy the challenge of building their very own dragster, and once the (30-piece) assembly is complete, they will have the option of racing their friends both indoors and outdoors! The Solar/Battery Top Fuel Dragster features a double XL solar panel that is strong enough to power the large frame on a sunny day. Run out of daylight, or it’s not sunny outside? No problem! Switch the power source of the Solar/Battery Top Fuel Dragster to the single AA battery compartment (battery not included), and the fun will not have to end. We envision “Blue Ribbon” capabilities at your next Science Fair!
