Here is you answer.
Here is the real story. When the Robinson R22 and R44 are rigged for cyclic control ranges the blades are rotated so that the pitch links are directly over the lateral or longitudinal axes of the helicopter. Unlike the Bell where the blades are disposed over either the longitudinal or lateral axes of the helicopter the Robinsons’ blades are offset 18-degrees ahead of the respective axes.
This means that when the cyclic is pushed forward from the neutral center the blades will have reached their maximum pitch input and with gyroscopic precession they will have their maximum response to that input 90-degrees later. That means, that the blades will tip down left of the longitudinal centerline. To counter this left tilt, the pilot must move his cyclic to the right.

I hope every Robbie driver reads your post as I have been advancing this premise since late last year and every on tells me I am full of it.
