A complete 220-piece kit to build a realistic helicopter, with rotor blades and gears that simulate real mechanical movements. The model features a system that allows the main rotor, tail rotor, and side rotors to rotate simultaneously, along with the vehicle's wheels. A practical and engaging STEM toy that allows children to see how propulsion and synchronized movements work. With the illustrated manual and 3D instructions, children learn to build independently, step by step! Part of the Science and Play Mechanics line, renewed by Clementoni with richer and more detailed components to offer the best in educational play. This is a quality product made in Italy. The helicopter that really takes off. Build your model and watch the blades and gears move, just like a real helicopter. Rotors that move together. The main rotor, tail rotor, and side rotors rotate perfectly in sync with the wheels for a truly realistic mechanical system. Learning mechanics through play. A kit that translates mechanical principles into practical experience: gears, transmission, and rotation, all within the child's grasp. Illustrated manual and 3D instructions. Each step is simple and clear, making building a fun, guided adventure. A complete mechanical experience, ready to be discovered. Part of the new Mechanics generation, which is more detailed and innovative, and entirely made in Italy.
