I don't know what the max. air speed is for the CJ with rear canopy back,
call it the safe canopy speed. But I found it safe and advisable to have
the GIB put the canopy back and locked upon landing. I tell them that it's
safe to move it back as long as the gear is down and we are landing.
(Three green.) If we do have a mishap they can get out a little easier.
The experience is better for them. The view is better, wind in the face
type thing. A feeling that they can touch their surroundings. I also slide
mine back.
On the other side of the coin, I have had a situation were you would think
that the canopy should have come off. The GIB failed to lock the canopy in
the closed position. We went into a loop and it slide back when in the
vertical. Coming out of the loop the canopy was still back, unknown to me.
He closed it at about 180 MPH. No damage. I'm thankful for the 5 point
Hooker harness. I go slightly negative over the top.
It's always an adventure since I usually have a new-be flying with me.

several of these were modified to ground attac role.
and shot down by the numbers as the O2's etc were.
We had one in Holland some years ago and I flew it for some airshows.
There was 'some vibration' in the airframe.......wonder why?
I would not like to be on the ground when one of these fly over,
unless sheltered and armed with FLAK.

| Subject: | Re: Canopy wide open |
I have inadvertently left my REAR canopy open and than dived my CJ-6 to near
the red line speed. Nothing happened. I have normally flown it at cruise
speed during photo sessions as a photo ship and have no hesitation to do so.
Now this is for the standard CJ-6 canopy. I do not know what aerodynamics
would effect the "Malcolm hood" canopies that are becoming so popular. I
can't imagine that it would be very much.
I do NOT fly with both canopy open at the same time. Years ago I removed
the plexiey glass from between the cockpits. Doing this allows the air stream
to very nearly blow the GIB clean out of the cockpit! :)
Though who have flown on my wing can tell you that I fly with my canopy open
a great deal of the time.
I not remember reading maximum speeds for the canopies in the manual that I
have. Maybe someone else has?
Since the Yak has pretty much the same construction, does the Yak have a
stated speed?
Here is where we need to have a "confession" time. Fess-up to what has
happened to us in regards to canopies. Its how we learn.
Some where in my photo collection I have a picture of a 3 of F-86 Sabers in
echelon left. All of them have their canopy slide back. Really cool
picture, (pardoned the bun).

More info from the web:
"Yak-52B - anti-partizan assoult aircraft. Two UB-32 rocket launchers. Also known
as Yak-54"
The rocket launchers appear to be UB-32-57 and carry 32 rockets each (57 refers
to diameter of the launch tube - 55mm for the rocket plus 2mm). Weight each
loaded (according to one site) is 264 kg (581 lbs) - unloaded weight is 226 lbs
each.

A little more info. this is a rough translation from russian:
Yak-52B-light plane, Yakovlev established on the basis of the education Yak-52
aircraft. The experience of the war in Afghanistan pointed to the need for combat
operations in light attack aircraft guerrilla movements. One of the projects
was the establishment of such an yakovlevsky Yak-52B (scheduled in the case
of production assign it a symbol Yak-54). The reference was made cheap and reliable
Yak-52 UTS. The aircraft made two pylon with a hung UB-32 blocks. .The
aircraft had strengthened wings. The plant was tested, but the fact that the
military had expressed interest in the plane, further work was stopped. The
only version of the aircraft was transferred to Aviamuzey in Monino.
Empty plane: 1100 - 2420 lbs
Max takeof: 1420 - 3124 lbs

FWIW, if you look at the location of the jack stand, it is neither under the
cowling nor under the wing or, based on the base legs of the jackstand, can
not be under the right wing or pod. Given this, what is your point of
significance about the jack stand?

Nothing more than it would be standing tall if the bird poop was washed off and
the jack stand was out of the picture. Air in the tire too. Its a shame that
it is being stored like that.
Warbirds or not, I hate seeing things just rotting.

That airplane is probably for sale and being billed as "the best maintained Yak
in the US". Probably a boat or an RV nearby as well.
Those pods look like ones I "liberated" from a junk yard in Balad, Iraq. If I
recall, they were off a MiG-23. Too bad we ran out of space on the home bound
Herk. (By the way, removing military hardware was legal as long as it was done
through the right channels.)

This will be the first of a few post....
I know this will vary based on location, but here in SW Ohio, I have seen some
pretty high oil temps while doing nothing more than tooling around the pattern.
A few times, approaching the red. At cruise on a cool (70* F) morning and at
2500msl, I have temps of 170 CHT and 70 oil.
Thoughts on getting those temps down a little? One -52 owner mentioned soaking
in some MEK for a few days then a cooler flush. Good temps since (on the low side
even).

A friend is considering a Yak and was curious about the average time people are
putting on their birds.
I put around 30 on mine last year but it was down for two months for a very extensive
annual (and the premature birth of my daughter) and then about a month
for a compressor problem.
Curious what you guys are putting on your crates.

Jay,
You would not believe what made it back to the states! Most of it legal, some..maybe
not. There were airplanes EVERYWHERE over there..peoples front lawns, parking
lots, stacked in piles. There was a junk yard that looked like the lot behind
some airplane scrappers facility. You literally could walk around and find
some totally random stuff. Shell casings, all kinds of documents, HUD's, seats,
helmets...JET ENGINES!
The Iraqi Air Forces was a shell of what it once was. We climbed around some MiG-25's
that were parked so close you could easily walk between them via the top
of their wings!
Anyways...

Just came back from Germany with a brandnew MTV-9-260 prop on my Yak 50.
The difference with the Russian propeller is apparent. Much more trust,
and also a lot of breaking power, so the first landings are somewhat
tricky. During my first test flight, I was at 2000 ft AGL in no time,
although it was very hot in Bavaria (30 degrees Celsius, quite unusual).
But as often with a Yak, something else popped up. The gas shock damper
of my tailwheel keeps loosing pressure. I have had problems with the
tailwheel before, but this is new. Luckily I always carry a small
nitrogen bottle with me when travelling (and the proper connectors), so
I could add some nitrogen before leaving Straubing, but when I made a
fuel stop after a one-hour flight, I immediately felt that it lost a lot
of pressure again. This means that I had to turn with more power while
taxiing, in order to lift the tailwheel which of course is not a good
thing. I suppose that the internal seals are worn out or something like
that.
Any idea ?

Tim,
I think cleaning the oil cooler is a great idea, however, to do it correctly
you need special tools and sometimes the cooler must be taken apart to
assure it is thoroughly clean.
The danger of only partially cleaning the cooler is that you don't know if
it contains metal or carbon particles that might come loose later with bad
results.

Tim, mine is the same. When the outside air temps get up past 90
degrees on a humid day, even pattern work gets me very very close to the
red markings on the oil temp. Pulling the oil cooler is not the most
difficult thing in the world to do, but it is not a lot of fun either.
It's a good thing though to pull that oil cooler shroud every now and
then and inspect that oil cooler BRACKET! Look at the top right and
left holes where it bolts into the aircraft and check for cracks. Very
few people pull that oil cooler shroud on the annual/conditional
inspection and check that oil cooler bracket. There is a company that I
can't remember the name of (but will find out) where you can send the
cooler, have it split apart, the cooler itself replaced keeping the end
"tanks" per se. This gives you a whole new cooler (more or less) and it
is what both of us should probably consider. I wonder though, because
the Sukhoi's here with the PF engines also run HOT HOT HOT in N.C.
summer weather. There is a lot of talk about somehow wrenching in a
BIGGER oil cooler.
Glad to hear I am not the only one suffering from that problem!

When I wrote that it was in reference to the 2 52s I had. Now I just have a 52
and 50.
The 50 was owned by some imbeciles in the past and, I have been working on it every
weekend since I got it in April. Also apparently some A&P butchers got their
hands on over the years too.
Ill get the old girl fixed up and going soon.

More info from the web:
"Yak-52B - anti-partizan assoult aircraft. Two UB-32 rocket launchers.
Also known as Yak-54"
The rocket launchers appear to be UB-32-57 and carry 32 rockets each (57
refers to diameter of the launch tube - 55mm for the rocket plus 2mm).
Weight each loaded (according to one site) is 264 kg (581 lbs) -
unloaded weight is 226 lbs each.

Seems like that can be an issue with -50's. Some take better care of their cars
than they do their airplanes. I am no mechanic so I put some to good use over
the past four years. They have returned my airplane to where it is now and I
feel great about flying it.
Did you buy a green one perhaps that was located in CA?

The oil temps on my Yak 52 are running pretty high these days. I'm up to 85
C after about 10 min of flying. I am flying it hard (running 85% power and
lots of inverted, outside, and vertical) and It is pretty hot here in southern
Ohio right now, about 91 F today I think. But I would still expect to be
running a little cooler. This winter I sent the cooler off to Pacific Oil Cooler
and had them flush it out and overhaul it, but it didn't seem to make a
difference. Any Ideas?
Thanks

This is the kind of data that I think we all need to collect. Just my
personal opinion.
Jay, what are your cylinder temps like?
I have seen two things that seem to control temps significantly.
1. Fuel. When you enrichen the mixture, it will cool the engine a
tremendous amount, and hence will impact oil temp. as well.
2. Condition of the piston rings. The older they get, the more
combustion blow-by gets into the oil and heats it up.
Lastly, and I hesitate to say this... To each his or her own, but.......
Before I change the oil, I let it get down to about 9 liters or so, and
then add about 3 quarts of MMO. I run the engine hard around the
pattern for at least 30 minutes being careful to not let the oil
over-temp. I then drain it all and add new fresh oil. I also pull the
oil screen and clean it as well when I do this.
Jay ... Many may disagree, but I would consider going a few clicks rich
on the main needle and see what it does for you. Heck, you can always
put it back when you are done.

| Subject: | Re: Average yearly use. |
I have to admit that while I had one amazing period where I flew about
200 hours with almost NO maintenance issues, the rest of the time has
been spent writing articles for the YAK list on yet one MORE thing that
managed to break at the worst possible moment. The list seems almost
endless.... And still going.
Here's a little addendum that can be added to the paper I wrote on the
50 electrical system.
The Combined Device can be by-passed by applying 28 volts switched power
to the terminal marked like a CAPITAL "A" on the Combined Device itself.
This terminal is on the right hand side above the main contact terminal.
Applying 28 VDC to this terminal will close the MAIN CONTACTOR RELAY
inside of the combined device, connecting the generator to the aircraft
MAINS with no safety provisions what-so-ever. If you do this with the
MAIN BATTERY SWITCH turned on, and the engine either not running, or at
low idle, you will have reverse current flow to the generator limited
only by the size of the wire. Another word for this is called a "short
circuit". You will cause significant damage to the aircraft wiring and
"other stuff" if you make this mistake.
On the other hand, if you know what you are doing, and have verified
that the generator is indeed putting out a regulated 28 VDC, then doing
this will allow you to start, take-off and fly on the battery alone.
Then at cruise power, you apply 28 volts to this LARGE "A" terminal and
you will manually close the main contactor and charge your battery
in-flight.
This should by no means be considered a "normal procedure". However, if
you are stranded west of East Jesus with a generator light and no easy
way home, you can use this method by first testing the generator for
proper output, then putting in an emergency wire to this contact which
will allow you to have manual control of battery charging in order to
get you home. Of course when doing this, a close eye (as in a GLUED
EYE) should be focused on the aircraft voltage/charging current meter so
that the contactor can be opened at the first sign of irregular
indication.
Make sure you understand exactly what you are doing/risking before
attempting something like this. It's just like a fire-arm. It can
either save your bacon, or put a hole directly into your foot.

Guys,
You need to be sure that your temp. probes are accurate. What I did was use
a cup of water with a coffee heater in it and run the water up to boil with
a probe in the water. I then adjusted the instrument to read 100 C They
were both off about 15 C

Does not sound like a problem Tim. 170C (CHT) and 70C (oil) is right where
they should be.
Can't speak to the Yak 50/52 but the CJ problem (with the Huosai) is cold
oil - barely 50C most of the time. CHT is easily controlled by the shutters.

Speaking of CJ's and Huosai's, has anyone figured out any oil mods (similar
to an inverted system) to keep from puking oil all over the place when doing
acro?

ubject: Yak-List: Average yearly use.
A friend is considering a Yak and was curious about the average time people
re putting on their birds.
I put around 30 on mine last year but it was down for two months for a very
xtensive annual (and the premature birth of my daughter) and then about a
onth for a compressor problem.
Curious what you guys are putting on your crates.
