here is an earlier video of it flying outdoors with some acrobatics and other demonstrations:

i still believe the perimeter flaps to be active somehow, they seem to react to control input rather than actual airflow, at a very low speed, some are up and some are at a 45 to the motor shaft. perhaps its supposed to act like the bell mouth on a ducted fan, but being able to cancel out lift in the area of desired direction.
