R66
I'm Flying SN0052 R66, and I'll tell you it is a great machine, nothing like a R44, plenty of power (I've done vertical take-offs at Max Gross), excellent fuel burn (84 lts hour I'm doing), great baggage compartment, great glide and way more stable than the R44. I'm always flying within limitations and I've had no problems so far. I'll go with the R66.
