The Russian manual also states it is recommended to land with the gear up.
Landing on unimproved or unprepared fields which may have ruts or pot holes
could be quite serious. Should one of the wheels encounter them, it may
cause the airplane to flip causing much more damage, including to yourself,
than with the gear up.

Scooter,
I can't remember but if you remove the unit you may find a grub scren that
locks the adjuster, that is typical Russian design.
Just a guess though

Here's what i have in my manual (Yak-52):
"ATTENTION! It is forbidden to stop the engine:
- by closing the fire cock, with fuel consumption within the carburator (to
avoid the flareback and the fire)."
"After the engine stop... the fire cock is closed when the airplane is in
the park, after flights performance".
And here's an unrelated question: Does anyone know how to adjust the VSI?
Mine reads a little negative when it should be zero. Is it that screw on
the bottom? I tried turning that and it was pretty stiff.

Well seems we have had this tread before. I got soundly thrashed about the
head and shoulders for suggesting that a CJ driver that landed in a corn
field barely missing an unseen pond or ditch (what ever) bring his bird to
a stop on plowed earth with his gear down was maybe not the best thing to
do. I stated he was lucky and the Russian Manuel calls for retracting or
keeping the gear retracted so as to land gear up on uprepaired surfaces.
The reason being, the center of gravity is lowered lessoning the chance of
flipping the aircraft on its back crushing the "little pointy heads" of
it's occupants. The last time I looked the 52, 50 and CJ did not come with
factory installed roll bars.
Just ask a couple of Aerocoup drivers that had an off field night landing
in what they knew was an open farming field behind a prison near the
airport here at Wetumpka, Al. Seems the dead motor was not going to get
them to the airport so the chose to land in a known area or at least that
is what they thought was known. Seems the prison farm detail had plowed
more of the field than expected. The first 100 yards were fine nice and
firm. It was that little dip into the soft dirt that got them a ride over
onto their back. The tail did keep them from completely being crushed. Both
survived. The right seater was unconscious for a ? period of time, had
raccoon eyes and generally looked like hell but had a uneventful recovery.
The left seater may or may not have been momentarily unconscious but did
escape through the rear canopy after kicking it out. He could not pull the
right seater out though because the aircraft was basically resting on his
side. The left seater began to developed headaches and double vision about
a week later. CT scan revealed he had a subdural hematoma. This was
surgically drained and he has had a full recovery.
But guess what, he is now grounded for up to 2 years. He has to undergo
serial EEGs, a cerebral angiogram and serial CT/ MRI's to document no
recurrence of the bleed, no ectopic seizure foci, or subsequent loss of
neural tissue from the coup counter coup brain injury. See, the force it
takes to tear blood vessel at the base of the brain also causes the brain
to squished against the skull as the head moves forward onto an unmovable
object. First that squish occurs as it stops moving forward in its watery
bath (known as cerebrospinal fluid) when it slams to a stop on the for head
portion of the skull. It then rebounds backward until it slams to a stop on
the occipital portion of the skull ( the back of the head). This creates a
nice bruise on the front and back parts of the cerebral cortex (the top
half of the brain). This can also occur when you hit the side of your head,
only now it is temporal to temporal motion. All kind of like bouncing a
ball.
Saying all this, for me it is a helmet and gear up if I have to land off
field. It is not worth the risk (for me that is). It is your choice and
your call. I have just stated what the FAA Medical Policy is on this
subject. If you are a military aviator (AF for sure and I am not sure about
Army or Navy, but probably very close), a subdural hematoma guarantees
permanent disqualification.
So to quote Clint Eastwood, "You feeling lucky, punk?" I am not saying you
may not end up on your back anyway, but the chances are less with the gear
retracted. That is all. Your choice and your call.

Welcome aboard, Norm,
One nice thing about Whirlwind 3-blade props (McCauley hub) is that in the
event of oil pressure loss the prop will go into high pitch, low drag
configuration. OTH, they generate a huge amount of drag in low pitch that
can be a handy brake on approach. Whirlwind does a beautiful overhaul on
V530 blades, too.

And the V530 does exactly the same thing should oil pressure be lost. It
goes to coarse/high pitch as well.

I just hung my prop this weekend after the Whirlwind overhaul. The prop looks incredible!
It looks like a different prop and for what they charge, you cant beat
it! I HIGHLY recommend having it done if your prop needs a little touch up!

Is it possible, and does anyone know how, to connected a western ADF to the
Gyro compass in the Yak-52?
