Flying isnt easy and not everyone can do it. You have to make sure you're tight enough for your bases to hold you in the air, and work on your stretches.

Soup can, Get a middle sized soup can and stand on one foot, this helps with your balance probally the most important thing other than being tight and holding our own weight so the bases dont have all of it :D

Im a flyer, and it isnt an easy job. You must get along with your bases. Stay tight and smile when you lift.
