To: Dave Jackson
Dave I would strongly advise to put your affairs in order and make out a will because you are going to get killed on this one. You have awakened two sleeping giants. One giant represents the believers in aerodynamic precession over gyroscopic precession. And, the other giant represents the believers in gyroscopic precession being the cause of the disc tilting in respect to cyclic input with no or minimal input from aerodynamics other than that force developed aerodynamically that causes the rotor (gyro) to nutate.
