The firefighters are prepared for a rescue operation using a helicopter or hovercraft that are awaiting construction. Kids can utilize more than 160 parts to construct an impressive rescue helicopter and a hovercraft, complete with functional mechanisms. The helicopter's wheels are linked to the rotors, causing the propellers to spin as the model moves, adding to its realism. Similarly, the hovercraft's propellers can be assembled to move, thanks to the included transmission components. The accompanying app provides 3D instructions to assist children in a step-by-step manner throughout the construction process.
