Check out Jean-Louis Naudin’s DIY UFO – a coanda effect flying saucer you can make yourself!
The GFS-UAV, propelled by an electric engine, uses the Coanda effect to take off vertically, fly, hover and land vertically ( VTOL ). There is no big rotor like on an helicopter and the flight is very stable and safe for the surrounding. The design of the GFS-UAV N-01A is based on the Geoff Hatton’ flying saucer from GFS Project limited.

I have a question:
How come it does not spin in mid air like a helicopter without a tail rotor?
This may help explain it:

A helicopter is not using its rotor to push air along a curved surface. This is more like a hybrid of a wing with lift effect, and a hovercraft. Very cool.
ohhhhh, stupid me, the fins are angled to counter the torque
