| Subject: | yak 50 landings and Russian radio |
Thanks for the recommendations, Mark!
I'll check the antenna cable and the antenna. The antenna is quite oxidated.
The Yak 50 is the 80-1807 used for 120 hours from september 1981 until
september 1983 in St Petersburg. Then it was stored and in 2002 overhauled
in the Shakthy factory. I am the second owner since. The former owner, a
Swedish pilot, never changed a bit on the plane. In total the plane has 195
hours.

OH BOY! I have never, EVER seen anything like THAT! You've sprung a new
one on me! What year is your YAK-50? I have a 1974 Yak and a 1985 Yak,
and NEITHER of them have anything that looks like that! Is the thing I am
looking at in your cockpit the actual RADIO? Or is it just a control head
with the actual radio being located someplace else? WOW... looks like
something brand new that no one else has! I have seen all the YAK-52
models too, and again.. NOTHING like that.
I would not worry about replacing that radio with something else that is not
"stock" because what you have in there now was never "stock" in a YAK-50
that I have ever seen or heard about.... and I have sat in about 10 or so
YAK-50's.
I have some Russian friends... I will show the picture to them and see what
they say.
Never-the-less, the recommendations I made about how to check the radio are
still accurate.
Wow.... something NEW!
Take care, and good luck... I'll be glad to help if I can!
Mark

Mark,
Here's a picture of the cockpit : everything in Russian as it came out of
the Shakthy factory in 2002. The radio has five knobs : two radio buttons
for the frequency (only 50 kHz separated); a volumeknob (bottom) and the two
toggle buttons. My plane is in a hangar 100 miles from my home. I"ll try to
have more data asap.
But thanks for your answer !

Jan's, I have two YAK-50's... one that is wrecked and is just used for
parts, the other I flew. I am also an Avionics Rep for the Marine Corps and
have done some repair on the Russian radios. Your description of the two
toggle buttons confuses me. There are two adjustments on the front of the
radio in a YAK-52, but not that I can remember on the YAK-50 radios. Can
you describe the radio that you have? Is it all one piece? Is there a
control head with a remote R/T ???
All of the radios I have dealt with have at least 5 watts of output power.
That's unmodulated carrier power. Peak envelope power is of course about 4
times that. There are a few models that put out even more power than that!
Regardless, with a good 5 watts, and a good antenna... I usually can achieve
ranges over 80 miles. Before I would suspect the radio as being bad, I
would pay particular attention to the coax line and the antenna. You need
to borrow a good in-line wattmeter and make some checks on forward and
reflected power, measured at the antenna AND at the back of the radio R/T
itself. Anyway, try to tell me more about what you have if you can.
Best Regards,
Mark Bitterlich

Hi guys,
I've got a Yak 50, Russian registered with the original radio. This radio
works fine but seems to have a very limited emission range (a few
miles).Does anyone of you knows how it works ? There are two toggle
buttons. The left one is for noise suppression, but I can't figure out what
the right one is for (it has the Russian word for "net" marked on it).
Since I'd liked to keep the plane as original as possible, I want to keep
the radio and want to try boosting the emission power.
About the landings, it is indeed special. I only had some fifty hours on
Pitts for tailwheel experience, but you certainly can't land it like the
Pitts. The Pitts is tailwheel-first. With the Yak 50 I always aim at doing
threewheelers and indeed somewhat slower than 150 km/h : about 130, 135 but
with a little bit of power as in a precautionary landing. I must admit that
I avoid flying with a lot of crosswind. I keep doing touch and go's in order
to improve my landings (on a grass strip). Fortunately the Yak 50 won't
groundloop as easy as the Pitts (I think).
Before flying the 50, I performed some landings from the back seat of a 52
but the lessons on the 52 were particularly helpful to learn about the
Russian technology, more than about the landings. So I agree with the others
: try to get some tailwheel experience before flying the Yak 50, not because
it 's so difficult to land, but because you're alone up there.

Hi all,
I am looking at purchasing a Yak 18T from a guy that advertises on Barnstormers.com.
He is located in Melbourne Australia. His name is Wojciech Drozdz. Has
anyone had dealings with this person?
Many thanks, regards Ant.

It's a real sucker to get it off when the engine is build in..but it's
possible. The standard Yak toolset has all the right keys etc.
Did it twice.. you need very small fingers (most important.) and a lot of
patience...didn't have the small fingers..the patience I had but it didn't
last very long..
Good luck Scott!

Get everything out of the way that you can. Remove the output check
valve and insert a plastic swizzle stick into the hole where you removed
the output check valve. Now have someone rotate the prop slowly. If
the compressor piston comes up and holds the plastic stick, the sheer
coupling is OK and the compressor is probably OK too. If it does not
hold the plastic stick, then assume the sheer coupling is sheered. You
will need a curved 11 mm box end wrench. There is one in the Russian
tool box with a T handle on it. Remove the 6 - 11 mm nuts to remove the
compressor. Getting them started when you want to reinstall it is the
challenge. You will need a lot of patience.

--> Yak-List message posted by: Walt Murphy <waltmurphy@charter.net>
A friend who instructs in T-34's and T-6's is willing to trade a little
acro instruction ( my airplane ) for some A&P time on his airplane.
The question I have is could someone give me normal entry speeds for
loops , rolls etc, only interested in pretty mild maneuvers just
positive G entry level stuff.
Any input would be most appreciated, thanks ,
Walt
Oh.. almost forgot.... how much oil should I limit the engine to ( to
keep the airplane from getting really messy? )
