With the screwed and plugged functional model, the heart of the original 911 becomes tangible and offers a unique personal experience. The high-quality kit has been crafted according to original drawings and consists of 290 individual parts, some of which are movable. The plastic components are assembled by screwing or plugging them together, ensuring a pleasant model-building experience – completely without glue. This allows the crankshaft, pistons, and valves to move in a faithful interplay. The transparent housing parts make the mechanics of the boxer engine visible and comprehensible from the outside. Even the ignition sparks in the cylinders are simulated with LEDs.
