Plus, it has an electronic engine sound and light-up spark plugs. About the product this build-it-yourself kit has everything you need to construct the engine, including all the parts, screws, and a screwdriver. Oh, and detailed, step-by-step instructions with diagrams. How is it powered there’s no actual petrol involved. This engine runs entirely off 3 aa batteries, which aren’t included.
