Although I wonder that if you already had traditional nutplate holes,
with the existing "satellite rivet holes", if this system would be
NOT the one to use... since it
uses radial compression to stay in the hole would those nearby
unfilled rivet holes compromise the strength of the device?
In other words- Is this system more for NEW construction as opposed
to retrofitting in existing nutplate locations?
p.s. I had stumbled on that website a while back and I just thought
it was neat... but don't know anyone using that system.

Depending on what you want to anchor to this may work.
http://www.mcmaster.com/#metric-rivet-nut/=th95d Simply drill out the
threads on the on the existing nut plate and install the rivet-nut.
Certainly easier than drilling out all the rivets an pressing in new nut
plates.
But guess this is not going to work on the Mig 21.

Hi,
Could somebody help out with S/N information on Yak 50? Need to know the
history of a plane that=92s for sale. The plane has logged over 11000
aerobatic cycles until 1983 flown 120:00hrs!!! Some opinion on that?

| Subject: | voltage and meter yak 18 |
Hi Mark,
Following on from the discussions here, I read the article that you
suggested. Can you tell me a little bit more about the combined
ampmeter/voltmeter that is in my yak 18. The standard reading with the
button depressed is a voltmeter and always shows 29 V. It always reads zero
at any other time, and I assume that this means either something is not
connected or is not working appropriately. Do you have any suggestions
about how I sort this out. In my aircraft the generator warning light
appears to be working perfectly and all of my electricals are working
perfectly. I am however about to have my aircraft upgraded to IFR, and
seeing as we are going to be playing with these things I thought it would be
sensible to ask
Cheers Stewart Graham

Subject: Yak-List: Voltage Regulation
Question regarding Voltage Regulation in a Yak 52.
First, this is a project airplane and has not been flown yet in the US. I
have gotten it running, but have no voltage regulation. When I first
started it, I had the Gen Fail light at low RPM...as I increased power @ 40%
the light went out(started charging) Around 45% the Gen Fail light would
come back on and pop the overvoltage breaker. I connected a voltmeter to
the DMR-200 as I ran it even if I adjusted the regulation screw...I got no
change in voltage. Volts increase with throttle until 45%RPM and kicks Gen
offline at @30.5 volts. I have tried another voltage regulator(it had been
sitting for 6-7 years unused) got the same symptoms.
Can anyone recommend more places to look, as most of you have a better
understanding of this electrical system than I do. My level of frustration
is tempting me to go with a B & C alternator/regulator. Any advice for or
against. If there is a problem in the system somewhere elsse...I don't want
to start frying B & C's.

Gill, with respect... If the generator puts out voltage, and the gen
light goes out when the engine RPM is increased past 40%, and then the
over-voltage circuit breaker pops at 30-31 volts, this is not a brush or
spring problem.
If the brushes or springs are completely bad, (either / or) you will
have no voltage at all out of the generator. If a spring is weak, you
will have intermittant voltage. I.E.: It will be turning on and off
rapidly.
Brushes and springs push against the commutator windings taking the AC
output of the windings and essentially giving you a DC output. Thus the
brushes and springs are critical to the generator putting out any output
AT ALL.
This is a regulation problem dealing with the probable loss of field
current from the voltage regulator.

The problem originally described was that the generator light went off at

brushes may not be making solid contact and should be easily checked as

From: "Bitterlich, Mark G CIV Det Cherry Point, MALS-14 64E"
<mark.bitterlich@navy.mil>
Well, as anyone who knows me has learned long ago, I never run away from
a good debate. So... That said, Gill, I do not know what you do for a
living, but I am a Avionics Field Engineer, and I am darn sure of what I
am talking about regarding this problem. Unfortunately what you are
passing to this gentleman is still incorrect and it is in fact ill
advised.
You said: "The problem originally described was that the generator light
went off at the normal point and then came on with increasing RPM, this
suggests that brushes may not be making solid contact and should be
easily checked as previously suggested."
You then also said: "I am not there so the mic (mechanic in command)
will have to decide."
First, you do not need to be an A&P to troubleshoot this. Most
mechanics are not familiar with very old design generator systems, and
it is a mistake to think that their word is gospel in a situation where
they are dealing with a foreign built aircraft that typically they have
no experience with. They also have to deal with minimum documentation
on the electrical system that usually is written in Cyrillic. Anyone
have a local A&P that speaks and reads Russian?
Second, your statement of what happened is out of context and
incomplete.
I have taken this electrical system apart piece by piece and I know
every single part and how it works and why it does what it does in ANY
situation. I wrote a complete white paper on this system that explains
it. So here's the COMPLETE breakdown of the whole problem.
READ IT VERY CAREFULLY BEFORE YOU REPLY PLEASE.
1. The generator light is on. He starts the engine. The light
remains on at idle. This is normal.
2. The engine RPM is increased. THE LIGHT GOES OUT. This is normal.
3. Now as the engine RPM is increased FURTHER, the generator light
COMES ON. In other words, we now have a fault. The only debate here is
what caused it to happen... You say it could be brushes or springs.
Well.. Read on.
3. As it went higher the OVER-VOLTAGE CIRCUIT BREAKER POPS and the Gen
light comes on again. It is SUPPOSED to come on when you have an
over-voltage condition. I'll tell you why later. But....Brushes and
springs can not cause a generator to put out too much voltage. That is
simply IMPOSSIBLE.
Let's review using the exact wording taken from the original message.
A. He said: "I connected a voltmeter to the DMR-200 as I ran it even if
I adjusted the regulation screw...I got no change in voltage."
STOP RIGHT THERE! Without going ANY further, just by that one statement
alone, he has a voltage regulation problem.
BUT, let's go on.
B. "as I increased power @ 40% the light went out(started charging"
OK, the GENERATOR IS NOW WORKING AND SUPPLYING POWER TO THE AIRCRAFT
BUS.
C. He says: "Volts increase with throttle until 45%RPM and kicks Gen
offline at @30.5 volts."
Please pay particular attention to the MEASURED VOLTAGE OF 30.5 VOLTS
DC!!!! That is EXACTLY what the system was designed to do. Take the
generator output off line if it puts out too much voltage. From the
Russian manuals, that is the exact voltage which causes it.
But if you are still not convinced, he also says:
D. "Around 45% the Gen Fail light would come back on and POP THE
OVERVOLTAGE CIRCUIT BREAKER" (emphasis mine)
Ah, yeah... That would be what the over-voltage control circuit is
designed to do. Pop the breaker, which opens the main contactor,
removing generator voltage from the aircraft and protecting aircraft
components and avionics from too much voltage.
When the generator has uncontrolled regulation, the voltage will
increase with RPM. This is why it is highly likely that the problem he
has is directly tied to the voltage control rheostat.
Any design engineer always puts in over-voltage protection. In the YAK
and Sukhoi series of aircraft, this is a big silver box that is
constructed so that when the voltage gets up to about 30-31 volts
(exactly as he said), an internal circuit breaker that is covered with a
little red piece of rubber, POPS and when it does, it opens the circuit
to the main contactor relay and removes all generator output from the
aircraft. When the main contactor opens, a sense wire goes LOW and this
opens another relay behind the instrument panel that TURNS ON THE
GENERATOR LIGHT. Again, this has ZERO to do with brushes and springs.
By the way, it is very easy to KEEP this circuit operational when
installing a B&C PMG or Alternator, or anything else for that matter.
This circuit is very reliable and worth keeping.
To continue: The generator light is coming on because the main contactor
opened after an over-voltage circuit breaker popped, and not because the
generator is not putting out voltage, as would be the case if the
brushes and springs were bad. No, the generator is working perfectly
just putting out TOO MUCH VOLTAGE, which is why it got disconnected from
the aircraft power mains.
Want to see it happen for yourself? Just like this guy is seeing? Take
the middle wire off of your generator in your aircraft. Connect a new
piece of wire directly from that middle generator contact directly to
the contact marked with the big PLUS (+) sign. Now start your engine.
It will do exactly what this mans airplane does. By the way, doing that
is not an advised method of testing your generator, but it is done all
the time in the field. If you try this, make sure you have all possible
switches in your aircraft turned off, because if your over-voltage
system happens not to work, you will end up frying all your avionics.
Watch your internal voltmeter very closely if you do this. It will go
up and down with RPM very rapidly. Like I said, I do not advise this as
a normal step by anyone with less than a complete knowledge of how this
system works. This test also has no bearing on the present problem. By
the way, it is also very doubtful that your mechanic will know anything
about a test like this. A&P's are usually very up to date on
ALTERNATORS, but not so hot on old generator designs.
ANYWAY.
Something most people do not know and I will explain here. What does
the generator light really tell you? What makes it come on and what
makes it turn off?
The generator light is simply an indication that tells you the position
of the main contactor relay that connects the generator to the aircraft.
If that relay is closed, the generator light goes out. If the main
contactor relay is open, the generator light comes on. It is that
simple.
The main contactor relay itself is controlled by a whole SLEW of OTHER
factors. Generator voltage, forward and reverse current, and lastly, by
over-voltage conditions. However, what it is NOT is any kind of direct
indication that the generator is, or is not, putting out voltage.
Merely whether a big relay is either OPEN or CLOSED. It can not be used
in any way to determine the condition or operation of the generators
brushes and springs EXCEPT IF IT IS FLICKERING. In that case, you very
well might want to check your brushes and springs.
Of course if there is any doubt, I would advise consulting with a Master
Russian Mechanic like Vladimir Yatremski. But keep in mind that he often
comes to me for help with this system.

springs. Make sure brushes are clean, move easily and are seated and
brush springs are properly installed.

Subject: Yak-List: Voltage Regulation
Question regarding Voltage Regulation in a Yak 52.
First, this is a project airplane and has not been flown yet in the US.
I have gotten it running, but have no voltage regulation. When I first
started it, I had the Gen Fail light at low RPM...as I increased power @
40% the light went out(started charging) Around 45% the Gen Fail light
would come back on and pop the overvoltage breaker. I connected a
voltmeter to the DMR-200 as I ran it even if I adjusted the regulation
screw...I got no change in voltage. Volts increase with throttle until
45%RPM and kicks Gen offline at @30.5 volts. I have tried another
voltage regulator(it had been sitting for 6-7 years unused) got the same
symptoms.
Can anyone recommend more places to look, as most of you have a better
understanding of this electrical system than I do. My level of
frustration is tempting me to go with a B & C alternator/regulator. Any
advice for or against. If there is a problem in the system somewhere
elsse...I don't want to start frying B & C's.
Thanks,
Chris Keating

Dear Listers,
Please read over the Yak-List Frequently Asked Questions (FAQ) below. The
complete Yak-List FAQ including the Usage Guidelines can be found at the
following URL:
http://www.matronics.com/FAQs/Yak-List.FAQ.html
Thank you,
Matt Dralle
Matronics Email List Administrator
[ Note: This FAQ was designed to be displayed with a fixed width font such as
Courier. Proportional fonts will cause display formatting errors. ]
This FAQ can also be viewed in HTML online at the following address:
http://www.matronics.com/FAQ/Yak-List.htm
************************************************************
******* LIST POLICIES AND FREQUENTLY ASKED QUESTIONS *******
************************************************************
PLEASE READ. This document contains Yak-List policies and information
for new and old subscribers. Understanding the Yak-List policies will
minimize problems for the Administrator, and will help keep the Yak-List
running smoothly for all of us.
******************************************
*** Quick Start Guide to List Features ***
******************************************
There are many features available on the Matronics Email Lists and each
one is described in detailed below. However, using the List Navigator
you can quickly access the complete set of features available for this
List. The List Navigator can be found at the following URL:
http://www.matronics.com/Navigator?Yak-List
****************************************
*** How to Subscribe and Unsubscribe ***
****************************************
Simply go to the Web Page shown below and enter your email address and
select the List(s) that you wish to subscribe or unsubscribed from. You
may also use the handy "Find" function to determine the exact syntax of
your email address as it is subscribed to the List. Please see the
complete instructions at the top of the Web Page for more information.
The Subscribe/Unsubscribe web page is:
http://www.matronics.com/subscribe
Note that you will receive TWO conformation emails regarding your subsciption
process. The first verifies that your subscription/unsubsciption request
was received, and the second confirms that the process has been completed.
You should receive the first email within a few minutes of your request.
The second conformation will arrive in less than 24 hours. You cannot post
until you receive the second conformation email message.
*****************************
*** How to Post a Message ***
*****************************
Send an email message to:
yak-list@matronics.com
Your message will be redistributed to everyone currently subscribed
to the List.
*****************************************************
*** SPAM Fighter - You Must be Subscribed to Post ***
*****************************************************
When a new post is received by the system, the From: line of the message
is checked and compared against the current subscription list. If the
email address is found, the message is passed on to the List Processor.
If the email address isn't found in the current list of subscribers, it
is dumped. This serves to very effectively thwart 99% of the SPAM that
gets posted to the Lists.
Remember, however, that the syntax of your email address is very important
with regard to the configuration of your email application such as Outlook
or Eudora. For example, the following two email addresses may be
functionally equivalent, but only one would pass the Matronics Email SPAM
test depending on which was syntax was subscribed to the given List:
smith@machine.domain.com
smith@domain.com
Either email address syntax is alright, just be sure that you configure
your email application to match *exactly* the address you've subscibed to
the List.
**************************************
*** Enclosure Support on the Lists ***
**************************************
Limited posting of enclosures such as pictures, documents, and spreadsheets
is supported on the Lists. There are a number of restrictions, and these
are detailed below. Please abide by the rules put forth regarding the
content of enclosures.
These are some of the features and limits of enclosures on the Matronics
Lists:
1) Enclosures will only be posted to the Real Time version of the Lists.
2) Enclosures will NOT be included in the Daily Digest version of the Lists.
3) Enclosures WILL BE forwarded on to the BBS Forum Web site.
4) Enclosures will NOT be appended to the Archives.
5) Enclosures will NOT be available in the List Browse feature.
6) Only the following file types and extensions will be allowed:
bmp doc dwg dxf gif jpg pdf png txt xls
All other enclosures types will be rejected and email returned to
sender. The enclosure types listed above are relatively safe from
a virus standpoint and don't pose a particularly large security risk.
7) !! All incoming enclosures will be scanned for viruses prior to posting
to the List. This is done in real time and will not slow down
the process of posting the message !!
Here are some rules for posting enclosures. Failure to abide by these rules
could result in the removal of a subscriber's email address from the Lists.
1) Pay attention to what you are posting!! Make sure that the files
you are enclosing aren't HUGE (greater that 1MB). Remember that there
are still people checking they're email via dial up modem. If you post
30MB worth of pictures, you are placing an unnecessary burden on these
folks and the rest of us, for that matter.
2) SCALE YOUR PICTURES DOWN!!! I don't want to see huge 3000 x 2000
pictures getting posted that are 3 or 4MB each. This is just
unacceptable. Use a program such as Photoshop to scale the picture
down to something on the order of 800 x 600 and try to keep the
file size to less-than 200KB, preferably much less.
Microsoft has a really awesome utility available for free that allows
you to Right-Click on a picture in Explorer and automatically
scale it down and resave it. This is a great utility - get it, use it!
http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
Look for the link "Image Resizer"
3) !! This would seem to go without saying, but I'll say it anyway. Do not
post anything that would be considered offensive by your grandmother.
And you know what I'm saying; I don't want to see anything even
questionable. !!
4) REMEMBER THIS: If you post a 1MB enclosure to a List with 1000 members
subscribed, your 1MB enclosure must be resent 1000 times amounting
to 1MB X 1000 = 1 Gigabyte of network traffic!! BE CAREFUL and
BE COURTEOUS!
Also see the section below on the Matronics Photo and File Share where
you can have your files and photos posted on the Matronics web server
for long time viewing and availability.
*******************
*** Digest Mode ***
*******************
Each day, starting at 12 midnight PST US, a new 'digest' will be started.
This digest will contain the same information that is currently appended
to the archive file. It has all of the headers except for the "From:"
and "Subject:" lines removed, and includes a message separator consisting
of a line of underscores.
Each day at 23:55 PST US, the day's messages as described above will be
combined and sent as a single message to everyone on the digest email list.
To subscribe to the digest list, use the same subscription web form
described above, and just select the Digest version of the List.
http://www.matronics.com/subscribe
Note that you *can* be subscribed to both the realtime and digest versions
of the List at the same time. This is perfectly acceptable.
Now some caveats:
* Messages sent to "yak-list-digest" will be forwarded to the standard
email list. In other words, you cannot post messages only to the
digest List.
* If you are subscribed to both the regular List and the digest List, you
will receive the realtime postings as well as the digest at the end of
the day.
* If you reply to the digest email, your message will be forwarded to the
normal list associated with the digest. Important Note: Please change
the subject line to reflect the topic of your response! Also, please
*do not include all or most of the digest in your reply*.
****************************
*** List Digest Browser ***
****************************
An archive of all the List Digests can be found online in either plain text
or HTML format. These archives contain the exact Digest that was posted to
the Digest email list on the given day. The Digest Archives can be found
at the following location:
http://www.matronics.com/digest
*****************************************
*** The "DO NOT ARCHIVE" Message Flag ***
*****************************************
At times, your message may concern something that is revelent only to a very
small number of persons or to a limited area, and you may not wish to archive
it. In such a case, simply put the following phrase anywhere in the
message:
do not archive
Your message will not be appended to the archive, but will be sent to List
email distribution as normal.
**********************************************
***** READ THIS - Automatic Unsubscribes *****
**********************************************
Note that if your email address begins to cause problems such as bounced
email, mailbox is filled, or any other errors, your address will be promptly
removed from the List. If you discover that you are no longer receiving
messages from the Yak-List, go to the following Web page, and look
for your email address and a possible reason for your removal.
The Matronics Email List uses utility called the "Email Weasel" that
automatically looks though the day's bounced email for addresses that
caused problems due to common things like "user is unknown", "mailbox
full", etc. If the Email Weasel removes your email address from the
Lists you will find record of it at the following URL:
http://www.matronics.com/unsubscribed
If the problem listed on the web site above has been resolved, please feel
free to resubscribe to the Lists of your choice.

****************************************
Recent messages posted to the Yak-List are also made available on
the Web for realtime browsing. Seven days worth of back postings are
available with this feature. The messages can be sorted by Subject,
Author, Date, or Message Thread. The Realtime List Browser indexes are
updated twice per hour at xx:15 and xx:45. You can also reply to a message
or start a new message directly from the List Browser Interface (coming soon).
You do not have to be subscribed to the given list to use the List
Browser Interface in view-mode.
http://www.matronics.com/browselist/yak-list
*******************************************
*** Web Forums Bulletin Board Interface ***
*******************************************
A phpBB BBS web Forums front end is available for all Yak-List content.
content. The Forums contain all of the same content available via the email
distribution and found on the various archive viewing formats such as the
List Browse, etc. Any posts on the web Forums will be cross posted to the
respective email List, and posts to the Email List will be cross posted to
the web Forums.
You may view all List content on the Forums without any special login.
If you wish to post a message via the Web Forum interface, however, you
will need to Register. This is a simple process that takes only a few
minutes. A link to the Registration page can be found at the top of the
main web Forums page. Note that registering on the Forum web site also
enables you to send email posts to the Lists as well. You will also need to

*********************************
*** Matronics Email List Wiki ***
*********************************
In an attempt to make it easy to store and find structured and often accessed
information, Matronics has installed a Wiki at:
http://wiki.matronics.com
The Wiki allows individuals to create web pages to contain useful information
for other users of the mailing lists and web site. Unlike an ordinary web page
where the content needs to be submitted to Matronics for inclusion, the Wiki
permits the users to construct their own pages and have them visible immediately.
While constructing pages for the Wiki is not difficult, some may not be
comfortable building pages. In that case, simply prepare the text and any
images and email it to:
wiki-support@matronics.com
One of the volunteers on that list will take your submission and construct
a Wiki page for you.
Often someone produces a particularly useful posting in email one one of the
Lists that would be of general interest. In that case Matronics may take that
post and convert it into a Wiki page.
*********************
*** List Archives ***

copy of it to everyone. To share your Files and Photos, simply email
them to:
pictures@matronics.com
!! ==> Please including the following information with each submission:
1) Email Lists that they are related to.
2) Your Full Name.
3) Your Email Address.
4) One line Subject description.
5) Multi-line, multi-paragraph description of topic.
6-x) One-line Description of each photo or file

for viruses. Please also note that the process of making the files and
photos available on the web site is a pseudo-manual process, and I try to
process them every few days.
Following the availability of the new Photoshare, an email message will be
sent to the Email Lists enumerated in 1) above indicating that the new
Share is available and what the direct URL to it is.

**********************************
*** List Support Contributions ***
**********************************
The Matronics Lists are run *completely* through the support of it members.
You won't find any PopUpAds, flashing Banner ads, or any other form of
annoying commercialism on either the Email Messages or the List web pages
associated with the Matronics Email Lists. Every year during November
I run a low-key, low-pressure "Fund Raiser" where, throughout the month,
I ask List members to make a Contribution in any amount with which they
are comfortable.
I will often offer free gifts with certain contribution levels during the
Fund Raiser to increase the participation. The gifts are usually donated
by companies that are themselves List members.
Your Contributions go directly to supporting the operation of the Lists
including the high-speed, business-class Internet connection, server
system hardware and software upgrades, and to partially offset the many
many hours I spend running, maintaining, upgrading, and developing the
variety of services found here.
Generally Contributions range from $20 to $100 and are completely voluntary
and non-compulsory. I ask only that if person enjoys the Lists and obtains
value from them, that they make a Contribution of equal magnitude.
Contributions are accepted throughout the year, and if you've just
subscribed, feel free to make a Contribution when you've settled in.
The website for making SSL Secure Contributions is listed below. There are
a variety of payment methods including Visa and MasterCard, PayPal, and
sending a personal check.
If you enjoy and value the List, won't you make a Contribution today to
support its continued operation?

Yak-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the Yak-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the Yak-List in the manner described below may result
in the removal of the subscribers from the List.
Yak-List Policy Statement
The purpose of the Yak-List is to provide a forum of discussion for
things related to this particular discussion group. The List's goals
are to serve as an information resource to its members; to deliver
high-quality content; to provide moral support; to foster camaraderie
among its members; and to support safe operation. Reaching these goals
requires the participation and cooperation of each and every member of
the List. To this end, the following guidelines have been established:
- Please keep all posts related to the List at some level. Do not submit
posts concerning computer viruses, urban legends, random humor, long
lost buddies' phone numbers, etc. etc.
- THINK carefully before you write. Ask yourself if your post will be
relevant to everyone. If you have to wonder about that, DON'T send it.
- Remember that your post will be included for posterity in an archive
that is growing in size at an extraordinary rate. Try to be concise and
terse in your posts. Avoid overly wordy and lengthy posts and
responses.
- Keep your signature brief. Please include your name, email address,
aircraft type/tail number, and geographic location. A short line
about where you are in the building process is also nice. Avoid
bulky signatures with character graphics; they consume unnecessary
space in the archive.
- DON'T post requests to the List for information when that info is
easily obtainable from other widely available sources. Consult the
web page or FAQ first.
- If you want to respond to a post, DO keep the "Subject:" line of
your response the same as that of the original post. This makes it
easy to find threads in the archive.
- When responding, NEVER quote the *entire* original post in your
response. DO use lines from the original post to help "tune in" the
reader to the topic at hand, but be selective. The impact that
quoting the entire original post has on the size of the archive
can not be overstated!
- When the poster asks you to respond to him/her personally, DO NOT
then go ahead and reply to the List. Be aware that clicking the
"reply" button on your mail package does not necessarily send your
response to the original poster. You might have to actively address
your response with the original poster's email address.
- DO NOT use the List to respond to a post unless you have something
to add that is relevant and has a broad appeal. "Way to go!", "I
agree", and "Congratulations" are all responses that are better sent
to the original poster directly, rather than to the List at large.
- When responding to others' posts, avoid the feeling that you need to
comment on every last point in their posts, unless you can truly
contribute something valuable.
- Feel free to disagree with other viewpoints, BUT keep your tone
polite and respectful. Don't make snide comments, personally attack
other listers, or take the moral high ground on an obviously
controversial issue. This will only cause a pointless debate that
will hurt feelings, waste bandwidth and resolve nothing.
- Occasional posts by vendors or individuals who are regularly
subscribed to a given List are considered acceptable. Posts by
List members promoting their respective products or items for sale
should be of a friendly, informal nature, and should not resemble
a typical SPAM message. The List isn't about commercialism, but
is about sharing information and knowledge. This applies to
everyone, including those who provide products to the entire
community. Informal presentation and moderation should be the
operatives with respect to advertising on the Lists.
