I have a friend who's deep into RC flight, and he says that current state-of-the-art in flapping models fly poorly. It seems like it would be easier to 1. Build something that looks like a bird soaring 2. Power it with either a ducted fan or a prop-on-top-of-the-wing design, either way so the prop wouldn’t be visible from the ground, but the wings don't have to (fully) flap -- maybe they move a little to give a life-like appearance.
