These things are pretty old but sometimes it's nice to see two dudes really happy about a piece of technology that really works. This ornithopter is made by the guys at FlappingFlight (http://www.flappingflight.com/) and comes in multiple models including the Park Hawk with "instant glide" feature that allows you to stop flapping and swoop around like a bird of prey at the touch of a button.
At $300 they're not extremely expensive and they're a nice change from the smoky sturm und drang of traditional RC fliers.
