I stumbled across this video a couple of days ago. The video is a short build video of modifying, in true MADmodder style, a diecast model tractor-trailer into an RC truck. With functional lights on both the tractor and the trailer. It looks like the tractor is controlled via a DIY Blue-tooth controller, and the trailer has an IR connection to the tractor for the trailer light control. The fact that he used a 1/150 scale die-cast model to do this is more like watch-making taken to another level.
Edit: The original link didn't work anymore, this one does.

The rig's ability to make a 180 degree turn on a lap-top touch-pad at the end of the video was pretty impressive too.
