The instruction manual includes detailed assembly steps along with physics theories and science applications so that children can learn basic knowledge of machinery and gears through play. Complete 10 galactic-themed models such as the moon rover curiosity, satellites, astronaut and more. Let children feel as if they are in the world such as the star movies while they build models. How to play : The all-new designed infrared remote control has a maximum distance of 8~10 meters and 4 independent channels so that children can play together without interference. The all-new infrared controller can independently control the forward/backward movement of 3 motors to allow the movement and actions of models to be even smoother. The included 80X and 2 40X motor boxes greatly increases torque to easily drive the models. Overlap or adjust block designs at will to create your unique and personal robot.
