"As one of the other reviewers has remarked, the operating features of this crane reveal themselves at the end of the build. It's fun to put together, but not obvious how the crane operates while building it. The steering is what I wanted to see, and it works well, controlled by either of two light on the cab. The three-knob operation of the crane itself is excellent, and the functioning stabilizers are totally necessary when the crane is fully extended. One of my favourites."
