Kaman/ kmax question  

Was watching a video of a Kmax logging.  Is there always a lot of cyclic / rotor feedback inflight.  My right arm would have been jello after 8 hrs.   I was in a H43 Kaman years ago and almost jumped out on start-up because I thought we were going into ground resonance !!  I was in the left seat not the right and I don't recall seeing that much Cyclic Shake but I had my eyes closed most ot the time.
