This is a fully functional, remote controlled subtractor drive with independent turn and drive function which are separately powered.

It features:

- robust design with custom-made differentials that can handle larger forces

- transparent, "airy" and parsimonious design

- "invisible" electricity, all integrated into the mainframe

- front and back lights with light switch integrated into the mainframe

- quadruple L-motor power (two linearly coupled blocks of two motors each)

- front shield

- triple speed freely hanging piston motor

- self-stabilizing and self-balancing design

- can be mounted with any superstructure, e.g. cranes, hoists, levers

Constructed to an 11/15 measure, fully compliant with the rules of LEGO. Only official LEGO parts are used and no parts are modified or altered.

Weight: about 4 lbs, dimensions ca. 30 x 25 x 30 cm

The chassis can be used as a basis for basically any vehicle that has to traverse difficult terrain, e.g. building machines, bulldozers, search & rescue vehicles, etc. It is designed to provide a multipurpose solution for a variety of tasks. If fitted with different superstructures on top, countless models can be constructed.
