I never cease to be amazed by the ingenuity that builders use to incorporate Power Functions into their LEGO models — in ever-increasing miniaturization. Robert H. (Robiwan_Kenobi) manages to fit a PF motor, RC receiver, and battery box into this fully self-contained DAF truck.

Hard to believe? Take a close look at the cutaway in the photo above, and be sure to watch the video.

Thanks for the tip, Duane!
