Jeff, all of the "advantages" you listed are cost benefits for the owner/operator/maintainer, *not* the pilot. That's great, but...in most normal circumstances, FADEC makes NOT ONE LITTLE BIT of difference to the pilot.
With respect to the target market for the R66 and the 505, I believe the pilot/owner/operator will, in the majority of cases, be the same person.
I'm don't know who pays for your flying, but I pay for mine and these things you criticize are an advantage for those of us who both fly and pay the bills.
