Alexander Van de Rostyne built Pixelito, a 6.9 gram remote-control helicopter. Pixelito is fully functional, with 4 channels of control via infra red. It has no servos and no swashplate. The swashplate is the mechanism that allows the spinning blades to be tilted forward or back or side to side, allowing the pilot to control where the helicopter goes. (link from Stocktrader).

The Swiss Federal Institute of Technology has developed an ultralight robotic aircraft that mimics the navigational abilities of a fly. The plane is completely autonomous, weighs 10 grams and has a 14 inch wingspan. It is designed to fly indoors, which is difficult because of the many potential obstacles. It can fly around a room completely unassisted for nearly five minutes.

The plane contains low-resolution "eyes", a tiny gyroscope and an onboard computer.
