UTIAS Ornithopter with brushless motors?

The UTIAS ornithopter flew for 14 seconds with jet powered assistance.EBJ wrote:wow.
I was under the impression no one ever made a full-scale ornithopter that successfully flew.
Does this qualify as a flight ?
I think when the first human-powered flight was achieved there were min-height requirements, and a turn requirement to be "official".
Does anyone know if an ornithopter has achieved "official" flight ?
Mother of god that motor is huge! Thanks for your post, it does seem that brushless motor technology is constantly advancing, the motor you posted is the largest outrunner I've seen so far that is relatively lightweight!bearing wrote:Of course there is brushless motors who can. Just look at a neighbor thread:

It's a matter of power-to-weight ratio. Batteries are heavy compared to liquid fuel. But if you look at the whole vehicle, the difference doesn't necessary have to be that different. With a clever use of the properties of the electric motor, an electric ornithopter might not be that far behind a jet driven one.
