Remember that the initial question was how the 162 compares to the R22.
The R22 is a helicopter designed by a talented engineer, manufactured in a state-of-the-art facility, constantly and exhaustively analyzed for ways to make it lighter, stronger and less expensive.
The 162 is a helicopter designed by a competent engineer, parts manufactured in a variety of facilities, assembled by whomever, and rarely analyzed except by the NTSB.
In the hangar where we keep our 300CBi and R22, we are renting a space to a gent who owns a 162F. Over the course of the 18 months he's owned it, he's hovered it aproximately 10 hours, while he's gotten his PPL and CPL in our R22.
He has replaced almost every part of the factory drivetrain with aftermarket parts in the Rotorway, as well as most of the cooling and ignition system. I daresay he has more hours working on the 162 than he has flying the R22.
To me, this makes the R22 a better helicopter than the 162. However, in my personal opinion, the R22 is at the bottom of the totem-pole of certificated, factory-built helicopters when you consider all aspects of utility and safety. If you are looking for a "flying car" for an experienced pilot, then the R22 fills the bill very well, as it is relatively fast, inexpensive to run, and mechanically very reliable.
If you are looking for a helicopter to learn from square one, I prefer the robust forgiveness of the Bell47, Schweizer 300CB/CBi or even the Enstrom 280/28.
