fixate many double inverted coanda motors, in a circular holder for the motors. the center one can be a little larger using the available space more usefully and powerful. see double inverted coanda motor concept design for more information on the functionality.

[the youtube video demonstrates a single, non inverted, non optimized coanda motor used for attaining lift].
