    Lots do actually - and not far from me either. But I'm not one of them...

    Had a friend working for a housing company a while ago. They built houses on some of the peat land in the northern suburbs...they had to sink piles EIGHT METRES down to make "stable" foundations. And even then they had to re-gib the whole lot of them a couple of times over. Very reassuring I'm sure.

    I lived in Christchurch years ago when Bexley was being developed. I still remember the nay-sayers warning about building on that land. Seems they may have had a point after all...

    Hindsight is a wunnerful thing, innit?

    ... you will want the other book, once you have read Apache...

    EDIT: Bugger. Your link to the book depository has lightened my wallet.
    Several books on the way!

    Apparently the issue is that people do use them for training, probably because of their cost, although they are not ideally suited:

    "...Due to its light weight and low inertia rotor system, the R22 is not forgiving of pilot error or sluggishness. After an engine failure, real or simulated, you and the instructor will have 1.6 seconds to lower the collective and enter an autorotation. Any delay beyond 1.6 seconds will be fatal as the rotor speed, once decayed below 80 percent, cannot be recovered. Frank Robinson did not design the R22 to be a trainer; he designed the R22 for a fast cruise speed and fuel efficiency. The R22 thus has a fast cruise speed, high fuel efficiency, and is a terrible trainer. Why do so many flight schools use the R22 for training? It is cheap to operate.
    If you are looking for a trainer, consider the Robinson R44 instead. The R44 has about 4 seconds of rotor inertia rather than 1.6. That gives a pilot time to hear the low rotor RPM warning horn, look at the gauges, come up with a plan, and implement the plan (i.e., lower the collective and enter the autorotation). Count out 4 seconds to yourself and then count out 1.6..."
