Four cylinders lying flat, firing outwards

Inline, Boxer & Rotary collection

Four cylinders lying flat, firing outwards

An air-cooled flat-four built from 868 pieces in chrome and 28.8 cm long, with its pistons firing outwards from both sides of the block instead of upwards. A chain drive runs along the length of the engine and red lighting switches on with a single button. It comes in a hand-cranked or a motorised version. Plan on three to five hours of building.
