Here is a video showing a motorized Tumbler Batmobile made of Legos. Enjoy.
Lego Technic Motorized Tumbler Batmobile:
Lego master Paweł “Sariel” Kmiec has bricked together the Batmobile from Chris Nolan’s Batman universe. The remote control Technic Tumbler matches the steering and suspension of the Tumblers from the Dark Knight franchise and has over a month-worth of bodywork alone. Sariel’s website has more information and details on the making of his Lego Tumbler and other projects.
