The firemen are ready to go on a rescue mission on a helicopter or hovercraft waiting to be built! Children can use over 160 components to build an incredible rescue helicopter and a hovercraft, with mechanisms that work for real. The helicopter wheels are connected to the rotors, so when the helicopter moves the propellers rotate, making the model even more realistic! The hovercraft propellers move for real, thanks to the transmission components to be assembled. The app with 3D instructions will guide the child step-by-step in building the models., Manufacturer: Clementoni
