The manual (At least the one I have) indicates that all Aresti maneuvers are
permitted. The issue is not to let the plane drop too much and the way down,
so that you do not overstress the elevator assembly.
I fly them in mine, but I would recommend tying a flow indicator to your
pitot tube (in other words a piece of string... very high tech...) so that
you can control exactly when the tail slide initiates. Then you can make
sure you do not hold the slide more than one length of the plane.
Of course I would emphatically recommend that you have been through full
safety courses and flat spin recovery training with your own aircraft before
you fly this type of advanced maneuver. As you surely know flat spin
recovery characteristics vary from plane to plane, and if you just got
yours, you should certainly go through the works, whatever your level of
proficiency in the CJ...
I do however suggest you get Gennady Elfimov's direct advice. His e-mail is
fly@skytrace.co.uk. Gennady is the best Yak 52 pilot and instructors I know
of. I am sure he can give you lots of advice.

Gday all!
I have just purchased a Yak 52 to keep my CJ company in the hangar and to
feel twice as insulted the next time there is a Yak vs CJ discussion!
Seriously though, one of the Yak manuals I have has several question marks
next to tail slides under the Aerobatics section. What is the consensus
amongst you Yak 52 gurus out there? Are tail slides ok or not? Thanks in
advance.
Egon.
P.S. Life sucks, dont it?

Speaking of tail slides.......
During the restoration of my 52 I removed the horiz stabilizer and upon
inspection noticed a crack in the doubler that joined or re-inforced the
two halves at the rear of the stab. The piece is shaped like a "V" with
a flat bottom. I fabricated an exact replica from a slightly thicker
piece 2023, drilled out the old piece and riveted on the new one. My
suggestion is that others inspect this area for cracks as well.

Egon;
First...good for you. Does that fill your hangar or are there to be
others?
Tailslides, ahhhh! I was trained in my -52 (also -55 and SU-29) by
Azat Zaydullin, Ukraine National Champ with 1000's of -52 hours. We did
tailslides, I believe the manual was shown to me to indicate "All Aresti
maneuver" are acceptable in the -52, the tailslides both wheels up and
wheels down are listed in Aresti.
The key, same in the Sukhoi, is to "freeze" the controls as the slide
initiates and absolutely- positively do not allow the controls to be
slammed around during the slide. This will take some effort at least
initially until you learn the pressures that will occur trying to rip
the stick out of your hands sometimes. When ailerons and rudder are not
perfectly centered and elevator is not forced to remain against the
stop.
I was also taught three tumbles (gyroscopics) in the -52, also flying
backwards somewhat during the tumble. Lomcevak, Abra-ca-dab-ra, Adel
Weiss. The -52 tolerates "Ulimited" figures well also prop @ 100% (I
know that gives some of you chills - and I respect that).
An authoritative source here in the US, I would say, is Nikolay
Timofeev. As an Aeronautical Engineer and as Russian three time World
Champion with at least 100's of -52 hours I would listen to him (as I do
RE:my SU-29). His e-mail niktim@earthlink.net Also a great one to
teach you proper tailslides or whatever, and available from FL.
You'll love the -52, do it all, get the best dual, make sure there is
nothing besides you and what clothes you decide to wear (pockets totally
empty) inside prior to any acro.
Oh yes, learn all the emergency recoveries, flat spins et al. You will
not - for sure - flat spin out of any tailslides. Why? Because, other
than landing and power off spins, the other time ALL power is removed
(prior to slide). No power - no flat spin. She may slide more or less
depending on technique but will always "play lawn dart" sooner or later
with that M14P on the front. Any power left on at the time of slide
makes her torque and not a pretty slide.
Respectfully, Rick B
Comments? Mark - you there?

Nico, Dennis and Rick....Thankyou. I had an Su-26 a few years back ( until a marital
re-arrangement turned it into a house! ) Nikolai Nikituk who I believe was
No. 2 in the world at the time coached me on the aircraft and I discovered
that aircraft limits were not really all that important to the Russians in that
style of flying. That being said, I have incredible respect for their ability
and their aircraft.
Rick, I am afraid that with two aeroplanes a Bar and a Juke Box, the hangar (Australian
spelling!) is almost full, but as it is all on my property, I guess I
will just have to build another hangar. ( Don't tell the Fiancee'!)
Cheers
Egon.

--> Yak-List message posted by: David Marsh <swampy@videotron.ca>
Folks,
I'd like some advise before getting up to my elbows in pneumatic parts
....... My Yak has got into the habit of not fully releasing one of the
wheel brakes. However, if I move the rudder pedals to and fro, the
differential braking releases the trapped air in the brake line and it
releases. From the system schematics, it appears that brake pressure
modulation (both direct and diferential) is done inside the differential
brake unit. If that is correct, I suspect a blob of gunk inside that unit.
So ; questions.
1. Is my diagnosis sound
2. Does anyone have a schematic for the inside of this unit (part number y
135)
3. Any tips on how to get the unit out.
Thaks all,
Dave.

Graeme......I have looked high and low and cannot find the fuses or
reg.....however, on the area where the reg used to be is a large
rectifier-looking device that I have seen on at least one other CJ....I do
not know if it is a replacement for the original, but if your research shows
that it is interchangeable, it is yours for the askin....I have no need of
it as I am selling out all CJ
stuff.....(http://www.barnstormers.com/cat.php.) Check barnstormers under
warbirds for peliminary pictures.....Marcus

--> Yak-List message posted by: "Frank Haertlein" <yak52driver@earthlink.net>
Deon;
I uploaded a hand drawn pic of the how the crack looked on the horiz
stab. It's not the best pic but it will give you the idea of where to
look and what to look for. Here's the link
http://home.earthlink.net/~yak52driver/crack.jpg
I recommend everyone look in this area as it seems other things I've
discovered have been found in other airplanes as well. For example,
remove your front seat and look in the area where the rudder cables come
thru the main spar. One of the fuel lines runs directly over the rudder
cable and if it should ever get bent downwards (likely if performing
maintenance in the front cockpit with the seat removed) it could be
touching the rudder cable. The rudder cable will then act like a saw and
eventually cut thru the fuel line. It happened to me so it's not
impossible in other airplanes.
