I assume they taught that the precession phase angle was 90 degrees and yet the Robinson blades are disposed 18-degrees from the respective axes during the rigging process. What did they tell you about where the blade disc would dip if the cyclic was pushed forward from the rigged neutral position?
In a previous posting to this forum (to which you made several replies), Frank Robinson explained the reason for the 18 degree Delta-3 angle that is incorporated into the R22/44 rotor system. It seems that either you simply ignored his explanation, or you are incapable of understanding it.
Numerous pilots with experience flying the Robinsons have stated in this forum that the ship does *not* behave in the manner you claim. Not only do you continue to ignore these statements, but you refuse even the opportunity to gain first-hand knowlege of the situation by actually flying in the ship with an experienced pilot. Somewhat like the clerics who refused to look through Galileo's telescope, you choose to remain blissful in your ignorance.
Perhaps you feel ignorance is bliss. But, if in fact you actually DO understand the effect of Delta-3, why do you believe it is *not* applicable to the behavior of the R22/44 rotor system in the manner that was explained by Mr. Robinson?
