This technical stuff is very heavy going so is far from clear for me.
I fly R22 and R44 and can't say that I notice any problem with cyclic positioning. I certainly don't have to compensate 18 degrees to the direction I want to fly in. I push forward - it goes forward - I push left - it goes left etc... Next time I am a passenger in an R22/R44 I will take some digital pictures of the cyclic position in various flight modes and post them here. However I don't think this will prove anything because its where the cyclic feels right rather than looks right that the pilot is concerned about.
A further point - while hovering the R22 I feel there is no cyclic pressure in any direction however in forward flight there is a pressure to the left, which the pilot has to compensate for by pressure to the right. This becomes more intense the faster you go. Surely this is caused by the dissemmetry of lift and is why the cyclic trim is operated in forward flight? Could this be what Vorticey was referring to? Sounds like he is also confusing dissymmetry of lift with flap back too. Flapback requires the cyclic to be pushed thru more forward but not right. In the R44 Raven the hydraulic controls mask any cyclic pressure/vibration anyway but I do remember in training the force needed to hold the cyclic in position in forward flight with the hydraulics off.
(Now is a good time to remind R44 pilots to make sure the hydraulics are ON before you lift).
