Or a gull.
They still had to add in a small downward-pointing vertical stabilizer in order to make the model bird maintain stable flight. So they are not quite there.
Still, I wonder about how much power is consumed by flapping the wings compared to a fixed wing and a prop, especially in scaling. There are quite a bit of timing and control issues in working a flapping wing. If it had been possible in an evolutionary sense to develop balanced high-speed rotational structures, birds might have also had propellers.*

ReplyDeleteIt's always a good idea to pay attention when Germans start experimenting with flight.
