Second test of the 2008 NURC robot by the NERDS. This test uses 6 x 4 model airplane propellers instead of the 80mm muffin fan blades for horizontal thrust. Vertical thrust is still the muffin fan. Also batteries were moved to the rear, and some of the "stuff" supporting the electronics was removed to reduce weight and make room inside. And there's a handle, and a light on top.
