ABSTRACT:
A toy vehicle is operatively driven by an electric motor having a storage capacitor coupled in parallel therewith. The capacitor and motor are coupled to a pair of underside contacts on the toy vehicle for charging. The toy vehicle underside further includes an aperture and an elongated slot. A cooperating charger/launcher includes a vehicle receiving surface upon which a wheel pedestal is positioned between the area at the rear of the vehicle for raising the vehicle rear wheels. The charger/launcher further includes an interlock post received within the aperture formed on the vehicle undersurface and a safety rib received within the elongated slot of the vehicle. A pair of electrical contacts are positioned on each side of the protective rib and are coupled to a battery supply within the launcher for charging the vehicle capacitor. A pit-stop recharger includes a pivotable gate and pit area within which a second recharging apparatus is provided.
