|Designers Idea Book|
8891 Designers Idea Book is a TECHNIC Idea book released in 1991. It contains a book of twelve instructions for a variety of TECHNIC models. As the set comes with no LEGO pieces, the models require pieces from other TECHNIC sets to be built. Many of the models make use of pneumatics and electric motors, and some also use the command module from 8094 Technic Control Center.
