Arrrj, My biggest concern about the R66 is the fact that there have been 2 inflight breakups of R66's within the first year. At this point there has been no reasonable explanation of what happened. Until that happens there will be a question hanging over the R66. My other big concern is that based on Robinson's past record, if Robinson finally comes out with a required fix, that as the owner I will have to fix it totally on my nickel. Even though the problem was most likely caused by Robinson's inadequate engineering.
