Tuesday Torque: Twelve Turning

You can read all about the Dornier DO-X on Wikipedia. It was first built with twelve 524 HP engines, which were swapped out for 610 HP Curtiss water-cooled V-12 engines, so the plane could reach a safe cruising altitude.  There were only three built, and there were many problems, but it was important from a pioneering and engineering standpoint.  This radio-controlled model appears much more airworthy than the original planes.
