Hi I am Andre Naude this is my first message. I have recently sold my
Mooney M20F and is now intersted in a Yak 52 or 18 T. My question is on
the maitanance cost of the Yak. These maintanance costs are minimized by
the salesman for being less expensive than the Mooney. I don't want my
into a bee nest again. What is the annuals the Tbo and Ad and mods onthe
engine and airframe. What type of rating should I have.

Yes, the maintenance cost is much less than a Mooney. Who is the
salesman you're talking to and where is he located? Annuals depend on
who is doing them and how well you have maintained your airplane
yourself in the previous year. Typically they average between $1000 and
$2000 US. Again it depends on how well you've maintained the airplane
during the previous year. Also, maintenance costs are a reflection of
how well the airplane was maintained before you owned it an if it had a
true overhaul recently. All of the Yak 52's I deliver are zero time
airframe, engine and propeller. In other words, perfect airplanes that
look and feel like new when you take delivery. In my humble opinion,
that is the only way to start off owning a Yak 52.
I do not recommend you purchase a used Yak 52 without a QUALIFIED
pre-purchase inspection. Without a pre-purchase inspection you could
be setting yourself up for a lot of costly repairs.
Feel free to call me if you'd like to discuss purchasing a "perfect" Yak
52. I'm in the U.S. and on central time. 334-285-2141.
Best regards,
Dennis

Walt,
This is based on personal experience only.
The CJ can roll from cruise speed. I have rolled mine at speeds as low as
115kts. Doesn't do the sharpest looking roll, but rolls nice non the less.
130kts does excellent rolls.
When I first started loops, I was told (this is generic) that one should
enter a loop at 2.5 X Vs, which in our case is just happens to be Va
(152kts). Now I have been known to loop it at slower speed (135-140kts) but
it makes for a smaller loop. Looping at higher airspeeds will produce a
larger loop. With 175kts, I end up gaining 1500ft when at the top (I have an
M14p). Even got 1800ft once or twice with a Vne entry. One must be careful
with entry speeds in excess of Va to not pull too hard and overstress this
beautiful flying machine. Normally, my loop are around 3.5Gs.
I haven't noticed a big oil spillage on my CJ when doing acro as long as I
remain positive. Whenever I go negative (inverted for a few seconds or four
point roll) then it starts to spit some of that black oil. Since you want to
remain on the + side of things, I wouldn't worry much about the oil. I would
just keep at your normal level.
Hope this helps,
Dan

Hi Andre,
there are a few of us also in South Africa here who own 52s and 18ts. Both
are great aircraft. I have a new rebuild 52 on it's way from Lithuainia to join
2 others at FAVG (Virginia) and four of us are looking at an 18t to share
to run as well (a true 4 seater) There are some 52s and 18ts for sale here,
but as Dave said, make sure you know it's History or get a "new" one. There a
couple of guys who can do a prepurchase inspection, but i use Vladimir an ex
USSR engineer, who worked on them for about 15 years. If i can be of any
help, please mail me. And, welcome to the Yak club!!

Hallo Gerald
Thanks for the info. I know about 4 in the market here in SA. They are
priced aroud R 400 - R450k. Perhaps I can import better (like Zero
hours) for the same price.

Walt,
Here's what I use:
Rolls - anything over 100 knots, but around 125 KIAS (around normal
cruise) is the nicest balance of roll rate and stick force required.
Loops & Cubans - 160 KIAS will give you a nice round loop with 4 G
pulls at the bottom. If you're not worried about roundness, 3 G's
will do 'er with margin over the top.
Immelman - 160-165 KIAS
Split S - less than 100 KIAS
Wing overs - can easily be accomplished from 140 KIAS....keep that
ball centered! ;)
If you're positive G the whole time, no need to worry about oil
level....and if you go negative, it won't matter how much you have in
there, you're gonna have a mess without a closed system. ;)
Standard disclaimer: None of the above is an endorsement for
performing aerobatics in a CJ. Obtain quality instruction and learn
to fly any maneuvers competently with a qualified pilot before
venturing out on your own. Know and rehearse stall/spin recovery
techniques prior to any aerobatic flight. Give your self sufficient
altitude to recover and or bailout of an unrecoverable situation.
Wear a parachute and have parameters for it's use determined before
getting in the cockpit. Kiss your wife and feed your dog...and most
importantly have that cheeseburger you've been putting off before you
go flying. ;)-
Have fun!
Barry

If you remove the entire output check valve, put your thumb over the
hole and have someone rotate the prop, the compressor should "push" your
thumb off the hole. If it does not, then either the sheer coupling or
compressor itself is bad. Also while you have the output check valve
out, make sure the little "piston" moves freely up and down. It is
spring loaded. If the compressor does move your finger off the hole
while rotating the prop, make sure the output check valve is working
properly. Many, many times the little piston is carboned up and no
longer opens. It this is the case, you will not charge your air system.
A carboned up output check valve may also cause the sheer coupling to
sheer due to backpressure. If both are OK (compressor and output check
valve, check the pop-off valve and make sure it is working properly.

| Subject: | Oil Temperature & Oil Cooler |
--> Yak-List message posted by: tamara_b@telus.net
I have 2 questions, every constructive
contribution is much appreciated:
1) the OAT is during the day around
30 to 35 Celsius and my oil temperature
in my CJ goes up to 85 Celsius and the
scavenge temp. around 125 Celsius.
Is that normal due the time of the year
or do I need a new oil cooler
(or have the old one steam-flushed)?
2) does the YAK 52 oil cooler fit in a CJ?
Thank you in advance.
cheers
