Build eight models of realistic heavy-duty construction vehicles and control them with a remote-control unit. The models can be controlled both to drive around on the floor and to move their work tools, such as buckets, shovels, Forks, and cranes.A 64-page, full-color manual guides you through model building with step-by-step illustrated instructions. Read the manual to learn how the real-life versions of these awesome machines are so powerful and how their various mechanisms function. Discover how they can use physics to their advantage to move massive amounts of soil and rock. Investigate the concepts of force, torque, and simple machines with these working models.
