Actually.... and just to keep the post going...

The flybar moves 90 degrees BEFORE the
main blades move.

If you want forward flight you move the right
stick forward. That makes the front of the
swash plate move down.

The advancing flybar paddle is then tilted down
90 degrees BEFORE the main blades.

That causes the advancing main blade to start
moving toward negative pitch (and the retreating
main blade to start going positive).

Thus you get forward flight.

If the system waited until the advancing main
blade was over the nose of the heli before it put
in any pitch you'd end up going right.

Wow that's hard to explain. I hope it makes sense.

Heli's without flybars get the proper lead times with
the use of gyro's. I'm not sure what sequence of
events take place in that case.

I believe input 90° prior to the output is the basis of gyroscopic procession
