#2Would it be practical to use a gyroscope to control one axis of rotation in a "drone" like this?

That is a cool idea, if you can get really light and efficient mechanical gyro.
A boring solution will be fins operated by micro servo/

#4Perhaps the attitude of each fan blade rotates independently. To angle the drone, say, forwards, the fan blades might angle flat when they're at the forward position, every cycle, and angle tilted at the backwards position?
Seems expensive and tricky though.

It could all be done with weight shifting:

Maybe shifting the battery?
I can't remember the details but as you shift weight and begin moving laterally, when you pick up lateral speed it interferes with the ducting effect or enhances it in some way can counter reacts against the movement, giving dynamic stability.

For what it's worth, the article says it isn't done with movable weights.

#7Could you flex the shape of the inner donut somehow to change the vortex?

That's how helicopters work, and it requires complicated mechanical linkages. Read the wiki article about swashplates for an introduction.

#9Coanda effect? Some little jets somewhere to entrain the flow?

#10I don't know a lot enough about aerodynamics or airflow to be sure, but could they be moving pieces of plastic on the inside of the donut to block some of the airflow on one side to make it bank in that direction?
