The Revell Engineers hydraulic excavator construction kit offers versatile building fun for young constructors. With a total of 177 parts, a detailed excavator with a functional crawler drive and a movable excavator arm can be built. The 3in1 concept makes it possible to create three different model variants for your own play construction site using the existing components. Putting together the robust plastic parts playfully promotes spatial awareness and fine motor skills. The movable elements, such as the excavator bucket, mimic real movements. Thanks to its sturdy construction, the finished model is ideal for varied use indoors and outdoors.
