I have a custom smoke system with an aluminum 6.5gal removeable tank in
the externally accessable baggage compartment. Dual injector, 24V pump
is mounted below the bagagge compartment, flex hose to the firewall with
#3 braided steel line and all AN connectors firewall forward. Uses
about 2 -3 gals/min.
Here's a link to see it in action. http://www.ustek.com/90gc/smoke.html
High speed low pass at 180kts. If anyone would like pics of the
install, I can take some this weekend and post them.
I use the the generic smoke oil version, also sold by others by brand
names for twice as much (a.k.a. super dri) bought direct from supplier
in 55gal drum for $280. If you need a source for it, call Superior
Chemical at 513-870-9271, ask for Beth and tell her you want the pilots
special price for "Mineral Seal Oil". Also goes by other name from
other suppliers, aka "Form Oil", "Corvus Oil", "Cannopus 13". etc.

Check with Vladimir at Ramona. He is putting together a smoke system for
my CJ that will cost the same as the Smoking Airplanes one.
His system will have an easy way to fill the smoke oil tank and will be
assembled from aircraft grade hardware throughout.

Group,
Here are comments by my manufacturer:
"Russian seals are probably fabricated from a natural rubber.- Rubber
is not at all tolerant of petro-chems and will eventually turn to a
gum.- The pneumatic system of the Yak will ingest oil even though
there
is an air/oil separator in the system.- As many Yak owners will attest
they find "grease" in the actuators when they are disassembled.- The
"grease" is probably oil mixed with air and water and some dissolved
rubber.- As for adding oil to the system, that is the owners choice
but
I personally would discourage the practice.- If you want to see the
results of a petro-chem on Russian seals, just take a seal, new or
used, and place it in a cup of oil.- It will swell, turn to mush and
be
absolutely useless.
-
In an ideal environment the pneumatic system would be clean, dry and
free of contaminants.- That is ideal but not realistic.- A properly
maintained system would be drained at the air/oil separator after every
engine run.- The air bottles removed and cleaned per the manual at
regular intervals and seals replaced as necessary.-
-
Our seals are made from a blend of synthetics composed of basic
Nitrile.- They are petro-chem resistant and will outlast Russian seals
but the pneumatic system must be maintained.-"
-Have a safe holiday weekend!

Hi all, I have a 90% chance of being in Sumter, NC for four months starting in
early June thru mid Sept. I have a Yak 55 and would like to find a place to keep
my plane while I am out there. Please search around and let me know the name
of anyone that might be willing to share a hangar or has one temporarily available
in about a 75 mile radius.
thanks in advance!

TX32 is N33 22' 35", W97 14' 36" or N33 22.58, W097 14.60 for the GPS.
http://maps.google.com/maps?q=33.376389,-97.243333+(TX32)&ll=33.376072,-97.243767&spn=0.016826,0.033689&t=h&z=16&om=1
So the plan would be to fly in there and park at the place in the NW corner?
AirNav sez:
Dimensions: 2900 x 100 ft. / 884 x 30 m
Surface: turf
STANDING WATER MIDFIELD DURG & AFT RAIN. RY SOFT WHEN WET
So that's, "If it rains Saturday night or Sunday morning, take the float
plane" -- or the situation is better than that?
Cheers,
Jon

Mark,
I believe on the 52 systems that the Russians put a mixture of alcohol,
gycerine and something else to the air tanks at inspection. This was a
thread a couple of years ago also. I agree with all you have said too. Like
I said in an earlier post, I do add sewing machine oil to the tank and have
not experienced a problem to date.
Now I have all new seals too though when the 52 came over from Lithuania.
The 50 had all its' actuator seals replaced in 2002 by Shakety. So I am
leary of adding machine oil to the tanks on the 50 when I pull them in a
couple of weeks. The Lithuanian seals actually come for the US.

Doc,
Rust is "issue A".
Seals crumbling apart is: "Issue B".
There are at least two types of landing gear actuator seals "out there"
for the YAK-50 that I know of alone. The original Russian seal, and a
replacement that is made here in the United States. The actual material
used in each of them is quite different. The American made seal is more
tolerant of oil. The Russian one will harden, yet still work perfectly
for many years without a problem. However, if it has hardened, and you
add oil, it will crumble and break apart like a piece of burnt wood in
your hands. This is not conjecture speaking here, this is experience.
When making broad, across the board suggestions like "adding oil to the
air system is a good thing", one has to be careful. There is nothing in
any Russian manual about adding oil into the air system. This is a case
of owners of these aircraft seeing rust ... Which is a bad thing.... And
then thinking: "Well, I will just add some oil to this problem which
will help solve that old corrosion issue".
Some of the worst corrosion is seen in the actuators, and there is a
reason for this. The actuators are in fact expansion chambers. Think
what happens when you allow compressed air to expand rapidly.
So we come back to the original problem. Corrosion. In the actuators,
you have several choices. On the 50, you can take them apart, blast off
any and all corrosion, and then paint them with the best epoxy polyamide
paint money can buy. Or you can have them made out of stainless steel
(one gent actually did that). The same thing goes for the air bottles.
Another "good idea" is to mount the air bottles upside down. When you
do that, any water that is in there will come right back out when you
release air for brakes or landing gear actuation.
If you can manage to eliminate the water, you can really slow down the
corrosion process "no matter what". The snot valve is one attempt
towards this. Adding a desiccant filter is yet another.
However, if you want to start adding oil into the air system, I would
strongly suggest you find out the exact type of seal in use on your
aircraft, get one in hand, and cover it with some of the oil you intend
on using. Wait a few months and then take another look at that seal.
Bottom line, if you have brand new landing gear and flap actuator seals,
you are a lot safer adding "oil" or whatever...to your air lines. If
you have an OLD Yak aircraft that has not had the seals replaced since
Christ was a Corporal, I would not rush right in and start squirting oil
all over creation.
I "rushed in".... I also then learned how to blow the gear and remove
and replace the seals in those actuators.
Your milage may vary,
Mark

Now this might be another place for MMO for sure! In the quest to find
101 uses for MMO, this might be #89.
Seriously, we have been adding 6 oz of machine oil along with removing,
draining, and drying the tanks at annual. Have not seen any rust in the
tanks to date. We generally get about 3 oz of the oil back and a few
droplets of water that is less that a couple of ccs'.

Mark- My thoughts exactly. Be very careful what you put in the air
system.
