that was very cool.

I wonder if it would scale up at all.

Needs another pair of rotor wings behind the first. You could lose the traditional prop then for pitch.

A single one would suffice, wouldn’t it?

You could also make it fully symmetric, with a rotor on each of the sides of an equilateral triangle (probably not the best setup for top speed)
