Reade,More gain will come from pressurizing the cockpit with fresh ram air
than trying to seal the cockpit against smoke entering it. Once you equal
or exceed the pressure outside when compared the the pressure inside the
smoke will become a non issue.

Hi Reade,
I was finding myself blinded by smoke in the cockpit during our airshow routine.
Makes it real hard to hang on the wing during loops and rolls! Photos showed
that I (sitting in the cockpit) was not able to be seen by someone outside
the plane because I was completely engulfed in smoke (and CO!!).
Through much experimentation, here is what worked for me to greatly reduce the
smoke level in the cockpit:
-Drop the lower panels where the wings and fuselage attach. Put a bright light
in each cockpit and crawl under the plane. Now you can see every gap to seal.
I used very light weight aluminum tape I bought at Lowes. You can skip your
Pilates class that day...you'll see what I mean. :D
-With any g loading above 1 g, the pilot's right side exhaust comes up over the
wing (and into the cockpit). The more AOA (g loading), the more smoke over the
wing. I greatly reduced my problem by removing that injector. The difference
in smoke produced is undetectable in video tapes make before and after. I
highly recommend a Smoking Airplane's injector. I never got a home made one
to work as well, and I tried a LOT of them. Not to say good home made ones don't
exist, but I never got one to work.
-Do not put the one injector high up in the exhaust system. Smoke leaks out of
every joint and finds its way into the cockpit.
Doing all the above will significantly reduce your cockpit smoke levels. Beware
however, during hammerheads, tumbles and such, you cannot help but get some
smoke in the cockpit. You just cannot totally eliminate it.
I hope we see your TD back East, flying with us next summer,
Steve

About all I can think of is to make certain the two sections of the chip
detector screen are perfectly aligned and tight. There are some "disks"
between the two sections and if they are loose, will allow the chip
detector screen in the rear section to shift around. Make certain the
nut on the front of the chip detector at the center of the end with the
rubber insulation is tight. A loose nut here will cause the looseness
in the two sections. This can cause an erroneous and intermittent chip
light to come on.
Carefully inspect the wiring from the chip detector screen back to
through the baffling and firewall. Any intermittent ground on this wire
will cause the chip light to come on.
Lastly, try replacing the chip detector screen assembly and see if the
problem disappears.
Let us know what you find.

Thanks, Doc!
We don't have any -52's for training. Roger Baker is a great guy,
knows the Yak very well (though he won't do inverted flat spins
anymore...imagine that), his email is f4ffm2@adelphia.net He's
located in San Diego.
For NoCal, I'd give Kregg Victory (occasional poster here and prime
time mechanic) a call as he's pretty well connected up there.

G'day to all,
can anyone tell me what are the characteristics of the original russian battery.
Mine has been exhausted yesterday because I've forgot to turn off the cockpit
light and now I have to charge the battery but I don't know what s the capacity
and type.
Sorry if this subject has already been discussed.
Thanks and kind regards

| Subject: | ultrasonic leak detectors |
I have used this type of tester extensively. That said, I'll throw this
out for what it is worth. These types of leak detectors were designed
for leaks where air is going OUT and not leaks where air is going IN. I
know this will probably open up a real can of worms, but my experience
has been that the sound is actually made by a high pressure source going
to a low(er) pressure and the noise itself is on the downside of that
event. Meaning that the ultrasonics made by air going IN to a vacuum
will be better heard INSIDE where the vacuum actually IS. Hard to
listen for there!
On the other hand, pressure leaking OUT has the sound OUTSIDE where the
ultrasonic mike USUALLY is easy to use.
I am not saying that the Ultrasonic leak detector will not pick up these
sounds. Only that they will be much weaker than normal and very hard to
hear.
If the vacuum leak is happening with a gasoline motor, a much easier
method is to use some sort of pressurized flammable gas in a can....
Such as starting fluid. I am not recommending starting fluid... I am
merely saying some people use it. Others use WD-40! No ... really! All
manner of different gases are used. ANYWAY.. You spray them around
where the engine is running where there might be a vacuum leak and
listen closely to what the engine then sounds like. It works.
Good luck.

This is not the answer you are looking for. Possibly Dennis, or Doug
knows. Servicing instructions are surely in the maint. card deck.
Sadly they are no where close to me at the moment. I am not even sure
they are lead-acid batteries. Something floating around in memory says
they might even be nickel-cadmium types!
Anyway:
What I am going to offer Didier is that most people .... No. ALL people
that I know have taken those batteries OUT, and have replaced them with
GELL CELL types. I have even done that on my UTVA-66. The aircraft
charging voltage is not quite perfect I will admit, but they last a long
long time and work extremely well. They also don't require any
servicing. Typically two 12 VDC batteries are used in series with some
kind of custom made case adapter to get them to fit right in existing
spaces. B&C sells them for the YAK and Sukhoi 50, SU-26,29,31 types...
But those are extremely small and light weight, (and very low
capacity)...... Designed for aerobatics I might add where every extra
pound is avoided! I use two very LARGE ones on the UTVA-66 (electric
starter). You can pretty much design any capacity you want to have,
limited only by "space" in the aircraft.
Lastly, take a real hard look at this:
http://www.batteryminders.com/batterycharger/catalog/BatteryMINDer-Aviat
ion-Specific-Gill-LT-Series-24-Volt-4A--p-16169.html
Made by BatteryMinder, and I have nothing to do with these people and
rarely recommend any product. That said, this thing is the cat's ass.
It works. It works well. And at New Bern, there are over 25 of them
running all the time, they're EVERYWHERE, and every single owner loves
them to death.

| Subject: | Re: YAK 18T Battery |
Didier,
The more I think about it, the more I am starting to think that what you
might indeed have here is a multi-cell ni-cad battery. What makes me
think that is the comment about the "two blocks of 10 cells". That
would mean that you have a 24 volt battery with 20 cells. Divide 24 by
20 and you get 1.2 That is the EXACT typical voltage for a single
NI-CAD cell. Nickel-cadmium batteries have a cadmium anode, nickel
oxyhydroxide cathode, and an electrolyte of an aqueous solution of
potassium hydroxide. They run slightly less voltage per cell than do
lead-acid type batteries.
Please be certain of what you are dealing with, and what exact kind of
battery you have before servicing or charging it. Certain very violent
and dangerous reactions can occur if any battery is serviced with the
wrong fluids, or charged in the wrong fashion, and this is most
certainly true with ni-cads. With a NI-CAD, you MUST have certain
current limitations when charging, or it can go into a thermal run-a-way
and blow up. As in KA-BOOM. Also once they start a thermal run-a-way,
you simply can not stop them by removing charging current. It's a
really bad thing. A really REALLY bad thing.
So until some one who really knows answers this question, and I simply
do not know for sure myself... Please be careful OK?
Best Regards,
Mark

This is not the answer you are looking for. Possibly Dennis, or Doug
knows. Servicing instructions are surely in the maint. card deck.
Sadly they are no where close to me at the moment. I am not even sure
they are lead-acid batteries. Something floating around in memory says
they might even be nickel-cadmium types!
Anyway:
What I am going to offer Didier is that most people .... No. ALL people
that I know have taken those batteries OUT, and have replaced them with
GELL CELL types. I have even done that on my UTVA-66. The aircraft
charging voltage is not quite perfect I will admit, but they last a long
long time and work extremely well. They also don't require any
servicing. Typically two 12 VDC batteries are used in series with some
kind of custom made case adapter to get them to fit right in existing
spaces. B&C sells them for the YAK and Sukhoi 50, SU-26,29,31 types...
But those are extremely small and light weight, (and very low
capacity)...... Designed for aerobatics I might add where every extra
pound is avoided! I use two very LARGE ones on the UTVA-66 (electric
starter). You can pretty much design any capacity you want to have,
limited only by "space" in the aircraft.
Lastly, take a real hard look at this:
http://www.batteryminders.com/batterycharger/catalog/BatteryMINDer-Aviat
ion-Specific-Gill-LT-Series-24-Volt-4A--p-16169.html
Made by BatteryMinder, and I have nothing to do with these people and
rarely recommend any product. That said, this thing is the cat's ass.
It works. It works well. And at New Bern, there are over 25 of them
running all the time, they're EVERYWHERE, and every single owner loves
them to death.

By the way, shall we fill the small cells (two blocks of ten cells) with
non mineral water like in the old time???
Or acid????
Thanks

Having done a number of CO studies on the 52 and the 50, Doug is correct.
Just sealing the exhaust gaps will not stop CO getting into the cockpit. The
52 however does have a positive pressure airflow via the trumpet receiving
fresh air from the nose of the aircraft. That is not enough to stop CO from
getting into the cockpit. Although the 52 does on average have less CO in
the cockpit than the 50. I have a different theory on why that is. It has to
do with the open hole that the tail wheel strut extends out of in the tail.
With airflow over the canopy, the pressure in the cockpit is decreased. That
creates a decrease in pressure in the aft fuselage sucking CO into the
aircraft. The CO also leaches into the cockpit through leaks in fairings
along with holes in the gear wells of the 50. This all driven by the lower
pressure inside the cockpit.
The CO is highest during engine start, run-up, high alpha maneuvers
in-flight, on landing, and during run-up to scavenge the sump. On average I
see levels as high as 50 ppm for the 52 and as high as 110 ppm in the 52.
After a while, I gave up on trying to block all of the CO out of the
aircraft and opted for a fresh air source that was 100% free of CO. That was
accomplished with using a scuba system and by using my MBU-12 aviators mask.
I only use the system for taxi, take off, landing and run-up for shut down.
Basically, I feel better after 2 or 3 sorties than I did before I went to
this system.
I have not tested the CJ with or without the NACA duct installed to vent air
into the cockpit.

Good point - sealing exhaust gaps did not work in my 55 either ...

The good thing is that nothing wrong happened up to today. I did a
charge of the battery on 24v and about 3 to7 amps for about 3 hours
ans listening to the bubbles I removed it.
Thanks to your warnings Mark
I agree with you Mark about the NiCad voltage. Now I will wait to know
more if anyone knows about it.
Richard or Dennis if you have any info even just the type it's fine.
Thanks a lot Mark, you saved my baterry (I hope) and perhaps more.
Kind regards

Didier,=C2- If you are on an airport or near one where there are corpera
te Jets or Turbo Prop Acft. contact their maintenance people, those airpla
nes all use Nicad batteries. Their mainrenance people will have the expert
ise and equipment to maintain Nicad batteries. They will probably be able
to identify type of battery=C2-you have.=C2-
