• Comprehensive set of 2359 pieces offers both a relaxing and mentally satisfying construction experience for adults interested in technical models and construction machinery. The hybrid excavator model is a functional vehicle inspired by real-life engineering. Throughout the construction process, technical understanding deepens as you develop the skills of piecing together, attention, and focus. The motorized system provides the user with four separate control functions: bucket or hammer accessories can be activated by the movement of the boom and arm. Manually controllable swivel body, movable tracks and opening cabin doors enhance both the realism and playability of the model. Elegant enough to be displayed for adults who love to explore high-performance machines, it is also a satisfactory choice with the construction process. In addition to the physical booklet, the steps are easy to follow thanks to the digital instructions provided through the LEGO Builder app, making the construction process more intuitive and visual.
