Hang on. If you are in steady flight and you deviate the cyclic laterally of course the helicopter will deviate in the direction of the movement. Your assumption is that forward cyclic will cause the disc to tilt to the left and will thus need right cyclic to maintain the forward direction.
If you are in forward flight you have already compensated for lateral displacement, CG position and blowback. The cyclic is out of the rigged neutral position. If in forward flight the swashplate is tilted down and most likely to the right. If you move the cyclic laterally to the left the swashplate will be in the neutral position laterally and tipped down over the nose. At this point there is no lateral cyclic input. If I am wrong the disc will not tilt to the left.

What you say about the movement of the helicopter as the cyclic is moved to the rigged neutral position is correct. The disc will follow the cyclic movement. When the cyclic reaches the rigged neutral position the movement will stop. My question is where is the disc at this point? Some of you have run the test on the ground and your findings say I am not correct in my beliefs and that's OK.

Take it one step further and perform the test in forward flight and If I am wrong I will shut up and this thread will die a natural death.
