Instructions for modifying of the Lego® Technic 8043 Motorized Excavator

into the

ULTIMATE 8043

This mod will give the 8043: * 8878 Rechargeable battery * Complete simultaneous control of all the motorized functions * Joystick-controller that works just like a real excavator * XL-motor for more comsiderable boom-lifting power * PF-lights * More realistic bucket looks & larger operating range * Larger orerating range for the dipper * Roof for the cabin * All gear-reduction has been moved to the undercarriage to reduce the side-effects of transferring the drivetrain through the turntable
