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 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.
