Dave Ware's Erector Flying Bird

Dave writes: "Here is my latest model from the Erector Design 4 set. The original plans call for the flexible wing materials of the bird to bend as they move. However there was not enough torque in the motor for this to happen. Maybe if it were a 4 battery pack instead of the 2 battery one supplied with this set, it might have worked. The design was changed to just have the wings flap."
