vector steer drone rotating kite thing

Don’t know what to make of this but
maybe it’s interesting

I would choose the word weird rather than interesting.

Though: if you have a non-moving actuator, devices with spin is quite possible, and still not get excessive wear on the actuators. Im not sure what such actuators would look like though. Using servos or propellers as actuators, spinning the body only makes it harder to control.

I guess the one benefit of a spinning device is the option to control two axes with only one actuator.

I wonder why a plane with annular wings doesn’t need to tilt upwards to remain airborne while a circoflex kite does.

More info on the plane:

I think his " Pendelstabilisierte Vektorsteuerung" is interesting.
