Build remote control models of heavy-duty construction vehicles.

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.

Build a bulldozer with a blade that can be raised and lowered, backhoe with a digging bucket that can move inward and outward, and a dump truck with a bump bed that can be raised up to empty its contents. Make a mobile crane truck with a crane are that moves up and down, skid loader with a bucket that also moves up and down, and a road grader with a scraper blade that turn left and right. Assemble a forklift with a fork that can be raised and lowered and a concrete mixer truck with a mixing drum that rotates. Instruction for two additional models - a reach forklift and a wheel tractor-scraper - are available online.

A 64-page, full-color canal guides you through model building with step-by-step illustrated instructions. Read the manual to learn how the real-life version 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.
