[...] Personally, I think the key to flying the
lazy-8 is to ensure that your pitching and banking moments are out of sync
with one another. I think too many CFIs teach them to be in sync which is
wrong.

I wouldn't be surprised if there's a different way to teach the maneuver for
every CFI that's out there.

However, the CFI that had the most success (out of two) teaching me the lazy
eight was the one who showed me that you pretty much only have to use
aileron right at the beginning of the maneuver. A little bit of roll input,
and then just a nice slow increase in back pressure (with ailerons neutral),
causes just the right amount of increase in bank angle throughout the first
half of the maneuver.

I'm not sure what "out of sync with each other" means (or "in sync" for that
matter), and maybe it just means the same as what I have found to work well.
Can you elaborate on your terminology?

Sure. At the start of the maneuver, no pitch, no bank, etc... Start
banking and pitching. Now, the maximum pitch occurs at the 45 degree point,
at which point the pitch is reduced to level at the 90 degree point in the
maneuver, and then the minimum pitch (max down) occurs at the 135 degree
point. So, the minimum and maximum pitch up and down occur at the 45, 135,
etc degree positions. However, the bank is zero at the start, and maximum
at the 90 degree position, and then zero again at the 'bottom'. So the
minimum and maximum bank left and right occur at the 0, 90, 180, etc
positions.

IMHO, if a student is simultaneously pitching and banking 'in sync', they
are doing it wrong. Recap: At the start, you start pitching and banking.
When you get to the 45 degree position, you keep increasing the bank, but
start decreasing the pitch etc. I believe the Jeppesen book shows this
well.
