dave:
yes the disc axis is changed by the blades flying into place!
yes the axis would try to advance as the disc was tilting!
(gyro. press.)
yes the pitch on the blades would change as the disc started advancing from the attitude induced by the pilot.
and when the gyroscpic precesion = the attitude pressure, from the blades trying to bring the disc back to the pilot induced attitude, it becomes nutral.
lu:
if the disc used gyroscopic procession to change the attidude, when the axis stopped changing, gyroscopic precession stops(forward flight) you would have a 90deg adjustment to make??
hows my theory
