Abstract
A toy vehicle has a drive wheel and a flywheel that are coupled together by a slip clutch which includes a flexible pawl extended from the drive wheel to the surface of the flywheel so that the drive wheel may be grasped and brought to an immediate stop without injury. The toy vehicle cooperates with the energizer-launcher so that the toy vehicle is spring catapulted therefrom upon release thereof. The energizer-launcher has a pistol grip handle with trigger for one-handed aiming and launching of the vehicle and a pull cord for accelerating the flywheel and drive wheel while the launcher is being held by the pistol grip handle. A tachometer may be provided on the energizer-launcher. The toy vehicle further may have a spark generator on the drive wheel which is activated by the rotation of the drive wheel after the vehicle is launched.
