Or, just put a camera on an eagle

"Recently in Paris, Sony strapped its Action Cam Mini on a white-tailed eagle named Victor. It flew from the top of the Eiffel Tower, over the Seine, and down into the Trocadéro Gardens.
The eagle's handler, Jacques Olivier Travers, is the head of the nonprofit organization Freedom, whose objective is to reintroduce the white-tailed eagle into its natural habitat in the French and Swiss Alps. These eagles have been extinct in France for more than 50 years."

No need for a quadcopter, apparently.
