AeroVironment video of flight tests of its Nano Hummingbird flapping-wing nano air vehicle, developed for DARPA. Battery-powered and remote-controlled, the hummingbird-like prototype uses flapping wings for propulsion and control. Carring a video camera and downlink, the prototype has a wingspan of 16cm () and weighs just 19 grams (). It can hover for 8 minutes, remaining stable in gusts up to 5mph, and reach up to 11mph in forward flight.
