Georgia River Cruiser (Macromia illinoiensis georgina), the more-colorful, southern variety of the Swift or Illinois River Cruiser.  In real life, these large dragonflies patrol long stretches of rivers and streams, have great endurance, can fly at high speed, and catch their prey in flight.  

Mine has a range of about 28 inches on account of needing to be tethered to a battery box.  Each wing is attached by a cross-axle which swings up and down and a flex-axle which is fixed at one end.  The idea was to give the wings a bit of "twist" when they move, generating forward thrust that might propel the MOC.   At the prototype stage, I thought it just might work.  Alas, with the addition of all the extra weight for eyes, legs, and tail, it was too heavy to move itself.  So I stuck a XL Motor on the boom and called it a day.
