My boy wanted a "building site" with several trucks + shovel and an excavator. We spend a lot of hours building these excellent creations. The red truck of Han is playable in manual mode with pneumatics for the tilt-bed. We had to modify this model due to the available elements but it worked out ok I think. The black truck of Han is from his stone trailer creation and is motorized but can be played in manual mode. The Hydraulic Excavator (motorized) is designed by Yannmar and the shovel is designed by Lego and the lifting is motorized. We had a lot of fun with this.
