This detailed building block kit replicates a classic V12 engine with mechanical functions. The 974-piece set made of robust plastic includes an M-motor and a battery box that drive the model electrically. Once switched on, the fan blades rotate and the visible gear structure is set in motion. An integrated mechanism allows you to manually switch between two speed levels. Striking gold-coloured cylinder pipes and a solid black base give the unit a high-end look. With assembled dimensions of 27.5 x 16 x 15.1 cm, the engine is ideal as a display piece for technology enthusiasts and collectors. Batteries for the included box are not included.
