Paweł "Sariel" Kmiec's goal was to create a LEGO Batmobile Tumbler with realistic steering and suspension. Not only did he succeed with that, he did an impressive job with the details of the vehicle. The only issue he ran into was that after doing numerous body rolls during turns that the body would end up coming apart.
Here are the stats from his website:
Power: electric (RC unit / battery box)
Dimensions: length 56 studs / width 34 studs / height 19 studs (not including antennae)
Weight: 2.344 kg
Suspension: front – full independent / rear – live axle
Propulsion: 2 x RC motor geared 1:3
Motors: 2 x RC motor, 1 x PF Medium
