The Cabri was certified in 2007, the R22 in 1979.
The Cabri has been in use for the 7 years since, without any great concerns. By the time the R22 had been in use for 7 years, there had been numerous fatalities and the FAA had seriously considered pulling the type certificate.
There had been revised MR blades, now up to revision 6(?) a specific training course which remains a requirement today in the US in certain circumstances.
The Cabri has had some revisions. Balance weights to reduce vibration and increase comfort. Trim tabs on the blades to improve comfort. Adjustable pedals to improve comfort.
Quite different.
If you enjoy driving a Mk 1 Escort on a daily basis, please do, but if you choose one over a new Fiesta because you can pick one up for a lower price, don't pretend you've made the best purchase in any more than a very narrow perspective.
