Robin R2160 Question

[huckleberry58]

Hi. I used to fly the R2160 afew years ago and it used to vibrate quite abit, much more than the cessnas and pipers that I flew. I only flew that one aircraft so couldn't compare with other types and the engineers couldn't find anything wrong. So was wondering if this is typical of the aircraft? It seemed to me that there was some sort of engine imbalance.

I used, until a year or so ago, to fly two examples of this type occasionally.

Didn't notice any undue vibration, but the impression I'm left with is that they do have a level of vibration in normal circumstances a little bit more than the PA28 examples I have flown.
