Transparent Four-Cylinder Engine Model Kit

Endorsed by Haynes (the world's #1 publisher of car repair manuals), this four-cylinder engine model kit is both educational and fun to build. It includes over 100 parts—including chrome-plated trim—plus all the tools needed to assemble them into a fully functional 1:4 scale model. Once completed, just press the button, and you'll hear the sound of the ignition; an electric motor will animate the whole rotating assembly, and the spark plugs will light up in sequence! The model has lots of transparent parts, so you can watch every valve, piston, and pulley. It requires two AA batteries (not included), and is recommended for ages 13 and up. The finished model measures 14 in. L x 12 in. H x 4 1/2 in. W. Show Less
