Basic Controls-
X- up
Square- down
L2- turn left
R2- turn right
L3- hover

How to move-
press the up arrow on the arrow buttons while holding x.  The
harder you
press x, the higher you will fly.  Press R2 or L2 to turn.  To
land press
square lightly.
*If you think that you are good at flying and you are comfortable with
the
controls, try this: Fly above a boat.(a couple of feet above it.) 
If you are
right on top of it, press triangle and you should have fell into the
boat. 
(Do this with one of those yachts, they are big, so you have a better
chance
of landing on it.)  This takes a few tries, but it is possible. 
(I did it
twice.)
