This time he has remote control! Kewl!
Very!
The Coanda effect appears to be a first cousin to the Bernoulli effect,
n'est-ce pas?
But what on Earth is a "piezo gyro"? It's a little dingus that's shown
stuck under the dome in the detailed pictures, and something in the text
suggested to me that it's the bit of magic that keeps the whole body
from counter-rotating due to the torque which must be applied to the
propellor. But "piezo"?? Like, you squeeze a quartz crystal just right
and its angular momentum increases? That can't be right...
