Just posting some more visual aids here...
The image above shows how we might start layering balls ("center four kites, face out to form a ball").
Outside of that, you'll see the next square of kites which would be "next ring of kites, face out to form a ball".
Outside of that, another square of kites, "next ring of kites, face out to form a ball".
Etc, etc.
Using this approach, we end up with five rings, one inside another...
==
Outer ring is one,
inner ring is 5, slow burst in order... One... Two... Three... Four... Five.
Back to balls in reverse... Five... Four... Three... Two... One.
==
Back in the ball positions, another move, probably the most difficult...
Inner ring turn to place their left wingtip toward the center (looks like a pinwheel).
Next ring out, turn to put your right wingtip toward the center.
Next ring out, turn to put your left wingtip toward the center.
Next ring out, turn to put your right wingtip toward the center.
Outside ring, turn to put your left wingtip toward the center.
(this puts the rings facing alternating directions
Now, fly forward
slowly, around your circle.
All kites turn to face the other way...
Now, fly forward
slowly, back to your original positions.
==
The trick to this whole thing is moderating speed, flying slowly... And to keep visual tabs on the shape YOU are a part of, like which ring in the scenario above.
If you get in the wrong place or bump into someone else, the only thing that cause catastrophe is if someone loses their hover and takes off too quickly, hover and work it out.
==
Own your hover, and remember more or less, where your "home" spot is in the grid...
The leader may call out "BACK TO GRID", and everyone should move at moderate speed back to their original "home" positions.
It never ceases to amaze me how reliably people respond when they hear "BACK TO GRID", it sorts itself out very quickly.

Remember, I will be working to put the most experienced pilots in the middle of the whole thing and along the bottom, with the less experienced pilots more high and outside in the grid... The info and images above should give you an idea of some of the hover and flight skills that we'll all want to practice before the event and on Mon/Tue/Wed before the largest mega fly attempts.
