Original LEGO® Technic Models
Andrew Bissell & Steve Robinson
Here is a small but powerful collection of original LEGO® Technic models:
two monstrous helicopters, a mobile crane, a hydraulic [pneumatic] "track machine" excavator,
and a hydraulic [pneumatic] roll-on roll-off flatbed wagon for transport.
All of the thumbnail images on these pages lead to larger images, many of which contain additional paragraphs of information.
The models are motorized by at least two different types of motors,
and you can download a couple impressive MPEG video clips showing the rotational mechanisms of one of the helicopters.
