Dragonfly
Radio Shack sells a RC Bi-Plane Ornithopter for $50. I bought one, and it actually DOES fly, after a fashion.
A Google search will find it but for some reason I failed in my attempts to copy/paste the link.
It is modeled after the insect, has a tail rotor, and thrust for rate of flapping.
Due to the weather here, I have limited experience with it. It hovers when headed into a 5 kt. headwind, and I didn't have the room to turn downwind. The EYES GLOW! Talk about awesomely Kewl.[8D]
