I thought the pendulum was from stirring the pot.
The Robinsons are very sensitive. The aircraft will only move because you make it!
IF you came from a B47 and your handling skills were a bit 'sloppy' then you will be moving about in the R44. I don't mean this as a criticism, just an observation. I went from an MD500 to a robbie and my handling skills were lousy. Simply being too heavy on the controls.
Be really light and don't move and it will stay where you want it to.
Try jumping to and from an R22 to a B206 and back on the same day, same handling skill needed.
As one of my chief pilots asked me, are you flying it or is it flying you?
