I don't post here often

and judging by your attitude later in this thread I'm sure most of us are
glad you don't.

I cannot imagine a flight
school allowing for one second more cooldown than is required by the
factory. Unless you are paying for time on the skids, instead of
collective time.

The R22 datcon works on engine running. The 44 runs on collective time.

If so, if you are paying for total Hobbs time, they
may be screwing you, check it out. No R22 needs a five minute cooldown
before clutch release.

Depends how hot you got it and the ambient temperature. You are looking for
_significant_ CHT reduction so as not to shock cool the engine, not an
arbitrary time. If the school owns the aircraft I'm sure they want the
engine to go TBO and so treat it kindly.

Just two minutes for coolodown, then release
clutch for thirty seconds, then get mixture guard off and pull mixture
out. Call Robinson Helicopters yourself and check it out. You may be
asked for that additional cooldown time simply to run up your tab if
you are paying for Hobbs time.

And I suppose they then run the clock back so they can avoid the time-due
maintenance the extra hobbs time would have clocked up?

Also, in one of your posts you state that after bringing the ship to a
hover after an approach you had a wind gust that pushed the ship into
a right yaw that was so extreme you had to add FULL left pedal to stop
it. I've flown R22s for a while and I have NEVER approached the need
for full left pedal. Ever.

Presumably then you haven't flown one in a stiff wind? A gusty crosswind
from the right can easily demand some heavy left pedal.

You also mention "shimmy and shaking" all the way down during an
approach. Are you getting into a settling w/ power situation? If you
are experiencing violent shaking let me assure you this isn't normal.

He didn't say violent, just shimmying and shaking. A slow and high approach
will do this. Once ETL is lost the thing will be hovering OGE and bangs
about bit. OK it's on the wrong part of both the curves that matter but
sometimes it's the safest or only way into a landing area. It doesn't make
it abnormal, just not ideal.

It's just that this Google Rotorcraft
forum seems to be frequented by mainly remote control helicopter
enthusists and the Rotorway/Safari/experimental deathwish crowd that
have very limited knowledge about flying and I would really want to
make ceratin that a novice flyer like yourself will give an accurate
account here so as not to confuse all the other readers here who have
not became heli pilots.

This is usenet, nothing to do with google.

Please understand I'm not trying to ridicule or be derisive of your
descriptions, I've been right where you are and I know the feelings
very well. I'd just like to urge you to write a diary with less
adjectives and bluster than what you are sometimes doing now. You are
(inadvertatntly I'm sure)making it sound as if some of your flights
are more akin to "The Right Stuff" movie footage than true flight
training, especially the "full left pedal" and "shaking" stuff. Either
that or your instructor needs to do a better job of instructing as I
can assure you this is not the way it's done.

From memory I think I found the whole training thing full of adjectives.
What seems normal now seemed fraught a few years ago.
