Both Wifi and Bluetooth are in the same 2.4Ghz band, i.e, a jammer will
also overpower a Bluetooth signal.
But why on earth do you or anybody else want to use a jammer? I.m.h.o the
use of these broad frequency spectrum polluters should be banned.
In Europe they are forbiddenluckily!

| Subject: | RE; Pneumatic Fittings |
Walter,
I recently posted the Yak hose listing with all the fitting
sizes. The Russian aviation fittings are not the same AN or standard
metric. The Russian flair is 40 deg., but close enough to 37 deg to
make it work in some cases. We offer a complete set of fittings for the
M14P that go to western AN fittings. We have in the past cut the Russian
threaded part off and welded on AN threaded parts of the fittings to
make a complete conversion. We also have new Russian hose materials and
offer a service where your hose sets and we replace the rubber.

Bill;
I have no direct experience with the Yak 52 tube fittings but am near
certain they are identical to the CJ. Someone please correct me if that
is not so.
The following is based on that assumption.
The flare angle is the aviation standard of 37 degs. which is also true
of all AN and MS hardware for =9Cflare type=9D tube fittings
(there is also an MS compression type).
If tube/pipe (rather than tube/tube) the pipe thread is universal. On
the small 6 mm tube fitting it is 1/8=9D pipe thread. The same as
AN, MS and SAE fittings.
The tube end thread is metric but, like SAE thread, there are coarse,
fine and very fine variants.
The Chinese utilized Russian thread standards (why I assume the CJ and
Yak are the same in this area). But I believe that Russia (and Eastern
Europe?) used a different thread pitch for this purpose than Western
Europe.
It is possible to mix and match fittings, tubing and =9CB=9D
nuts (with varying degree of complexity) utilizing AN and
Chinese/Russian in the 6 and 8 mm tube sizes. Not too likely in the
10 and 14 mm sizes.
It is quite possible that some Yak/CJ owners have used SAE fittings
rather than AN standard assuming they are physically the same due same
thread on both ends. Where SAE differs is the tube flare. It is 45
degs. (90 degs in SAE parlance) NOT the aviation standard of 37 degs.
Hope that helps a bit.

Thought I would chime in on this one a couple years back my mechanic
suggested new hose for my Yak 52 and I felt it would be wonderful to
order up a complete set of hoses and started a quest to find someone
with a complete set of hoses sitting on a shelf ready for delivery
called the factory Aerostar no luck then started calling in the US
everyone said send your hoses to me and I'll put new hose on your
fittings, by the way if you do go this route Jill has your old fittings
cad plated and they look new when finished where my hoses were done did
not do the cad plating. Then I found a company that sold metric fittings
so I grabbed a couple Yak 52 fitting's and presented the Yak 52
fitting's to this dealer and found that the metric threads are NOT
standard and the matting surface is also not standard I think it was 5
or 10 degrees from standard. He did mention that fittings could be
machined with a minimum order of 100 at $45.00 each and I think there
are 15 to 20 different fittings.
Long story short sure would be nice to order up a complete set of hoses
at a reasonable price but I found this unlikely send your hoses to Jill.
Dan I've had broken fittings repaired at the machine shop or call Doug

Try a tractor supply, many of the new tractors (foreign ones) are now
metric. May or may not be the same.

1. Not a YAK-LIST topic.
2. It is illegal in most countries, including the U.S.
3. This is a PUBLIC SITE and what you say here can be used against you.
Enough said.

George;
Maybe you should read my post again. I (clearly, I thought) described
the differences between AN and Russian/Chinese tube fittings which in
fact is only the thread attaching the =9CB=9D nut.
I did indicate that I am not specifically familiar with the Yak 52 which
was the aircraft of concern for the original poster.
However I can very positively assure you that the Russian Standard tube
flare angle for Pneumatic, Fuel and Oil system tubing and fittings is
exactly 37.5 degs. (included angle of 75 degs.) and this is precisely
the same as the Chinese and Polish aircraft standard. It is also
precisely the same flare angle as the AN standard.
(I dropped the .5 for simplicity in my post)
Perhaps you are comparing your fittings to hardware store (non-aviation)
SAE fittings which are 45 (90) degs.
Suggest you do an actual measurement of the angle for your own
enlightenment.
