A complete 220-piece set to build a realistic helicopter, with rotor blades and gears that mimic 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 lets children 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, updated by Clementoni with richer and more detailed parts 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 on a real helicopter. Rotors that move together. The main rotor, tail rotor, and side rotors rotate perfectly synchronously with the wheels for a truly realistic mechanical system. Learn mechanics through play. A set that translates mechanical principles into practical experience: gears, transmission, and rotation, all within the child's reach. Illustrated manual and 3D instructions. Every step is simple and clear, making building a fun, guided adventure. A complete mechanical experience, ready to be discovered.
