An inline-four is the engine inside most cars on the road, and building a miniature one teaches you exactly how it works. These kits run on gasoline and are water-cooled, with OHV, flathead and DOHC designs to choose from.
They suit display stands, RC cars and boats alike. If you want to go further, there's an inline-six here too.
