Anyone have experience's with champion spark plug RVL 38S on the M-14p?

Ps: Auto ignition kit is not in the question, or an option for saving cash. Have a KIT for sale if anyone would like that.

You still looking for an engine? Getting ready to swap mine. It's running great,
but I got a factory new one in a crate I want to install before it gets old
and corrodes!

Hello Havard,

I'm curious as to why you seem to be unhappy with the automotive plug
conversion kit. I suspect there are over 300 (Dennis – you probably have an
accurate figure) in use around the world, and I've never heard of anyone,
until you, who is not absolutely delighted with them. My personal view is
that they are the best thing you can do for these engines for the money!

Other than the fact that it will cost you about $1900.00 for one set of 18 plugs, ($112.75 each), I have no other knowledge about these plugs.
The issue with the ignition system on the M14 is the wiring harness. Not the spark plugs. Replacing the wiring harness with the automotive conversion kit eliminates the "Achilles heal" of the M14 AND by default let's us use a less than $4 spark plug.
There are over 650 automotive conversion kits shipped world wide.

Hi Richard,

I had mounted the auto kit and experienced more radio noise, more and faster arching on distributor caps, breaker points. Checked the cables and the resistence on the cable i got is higher than original wire type cable, with the result in arching and noise. Maybe if used wire type auto cables its better.

Have now got the original harness rewired with wire style cables by M-14P. Mounted new caps and breaker points. Have flown great last 50 flight hrs. Last weekend flying 8 tours. Last tour ended with the classic coil problem. Got missfire After airbourne. Did check all the plugs(now original) with pressure tester. Found 4 to be not good, replaced them with new and made a test flight but same issue when airbourne. Know i had to take mag check airbourne to get it to missfire. When runnend on both it was pretty nice, but not perfect so did take the mag check and pointed on no2 it missfire like hell😄

I have the same radio and have interference problems also. That radio is poorly shielded as I understand. Was designed for gliders.

A friend of mine is also having interference issues since he fitted an automotive ignition plug conversion. His Yak 52 doesn't have a radio, but the noise is over the standard Russian intercom.

He has changed the magnetos with a known good one but still no better.

Has anyone found a solution to this issue? He doesn't want to go back to the old leads and I am going to be fitting a kit to mine once the Russian leads die.

Cheers
Chris

Hi,
Yes some told me that also, but checked some and Found the radio commonly used in noisy Aircraft.
Radio noise also on my friends Yak 52W with Icom 210A and NAT intercom. Also modified with auto ignition.
Anyhow, for me the auto kit is no more present in my Yak and the question here is og someone had experience's with the champion spark plugs.
Also if some have a new KIT with the original plugs i Could be intrested in buying that:-)

The original Russian cables are 5mm thick. The modern ignition cables are
thicker, so you can¹t pull them thru the wiring harness.
Otherwise I would have kept it.

The modern plug cables also pass higher frequency components to the plug.
Therefore, more energy goes to the plug and you get a hotter spark.

As for the radio noise: a careful installation of a good radio could fix
that.
In EASA country, every Yak owner will have to replace the old Baklans or
other 25 kHz separated radio¹s with a modern 8.33 kHz separated model soon
(2017, I think).

I personally am very satisfied with Dennis¹ plug wiring solution. I have
done several installations of it but also often changed the Russian
radio¹s.

Years ago, I had a Russian Ziabrik radio on my 50. This was a terribly bad
radio, still 50 kHz separated.
So I changed it for a Briz (or something like that). Only a slight
improvement.

Then I installed a Becker 4201 on my noisy Yak 50 and it worked
flawlessly. But I also changed the whole radio wiring, inclusive
PTT-cables, antenna and antenna cables etc.
Today I have a 8.33 kHz Filser Funkwerk ATR833.

Still the 8mm spiro-wound plug wires + NGK plugs AND an electronic
ignition in place of the right mag (Mark Bitterlich¹s design).

Very hot sparks, 120 kiloJoules, and more than one spark each time
(capacitive discharge, multiple spark system).

Radio works perfectly, engine sparks perfectly too and has consistently
higher CHT¹s since the electronic ignition.
(at)Dennis: I installed colder NGK¹s, the BR7HS instead, => gives me more
equal CHT temperatures on my M14R 450 PS.

Chris and all,

I am using the automotive kit already for the last 6 years or so on my Yak52
and have no problems with it.
The radio I have been using until last year was a Becker 4201. Since august
last year I have a new radio because of the necessity for us in Europe to
change to 8.33 channel separation. This new radio is a Becker 6201. Pin
compatible(almost) with the 4201. Intercom is a PS Engineering PM1000.
Measurements I have done showed that the noise generated by the automotive
ignition kit is less than the original one. I have no noise whatsoever on my
radio and/or intercom.

You are talking about interference. With all do respect it has nothing to do
with interference but solely with the proper installation of the intercom
and the radio. From a electrical noise point of view the Yak by definition
is a terrible environment. DC generator, mechanical DC regulator, tacho
generator etc. In general noise enters a radio through the antenna.
When the noise enters the radio through the power supply it can be solved
easily by means of a filter which is readily available from Spruce. In your
case whereby you have noise on the intercom it can be solved satisfactory by
means of the use of a power filter on intercom's power input.

So what can be do more?
It all has to do with proper installation of the intercom and the radio.
Nowadays the modern radio's we use have digital IF and are less sensitive
for noise. They are well designed and the majority have DSP noise
suppression.
In order to find out whether noise is coming in the radio through the
antenna the best thing to do is to unscrew the antenna from the radio and
short circuit the connector(mostly a BNC). DO NOT PUSH THE PTT AT THIS POINT
BECAUSE YOU WILL PROBABLY BLOW UP THE FINAL AMPLIFIER OF THE TRANSMITTER.
If the noise is still there it will for almost certainly come into the radio
through the power supply. In that case install a powersupply noise
suppressor filter and a capacitor on the "plus" coming from the generator.

If the noise comes into the radio through the antenna there is really not a
lot you can do but in all cases my recommendation would be to install noise
suppressor filters on both magnets as well, i.e. on the leads which go to
the mag switch. These wires radiate a lot of noise and this radiated noise
can easily be suppressed by a capacitor. Normally these wires should be
shielded but in due time the shielding may have come loose from earth or are
terribly damaged.

Also make sure the radio is installed properly, that means, use the right
shielded cable. Do not connect ground to the shielding on both sides but
ONLY connect the shielding on the radioside. Ensure a good earth.

The problem with noise coming through the antenna is that noise is AM
modulated, which is the same type of modulation of the signals we generate
and receive with our radio. In other words our VHF radio is well equipped to
receive this type of noise. The design of the radio is there for also
important. Poorly designed radio's are much more susceptible to noise than
properly designed ones.
In our Yak environment I would go for the bigger names like Becker,
Funkwerk, Garmin, King etc. In this case it is fair to say:the cheaper the
radio the more chances you have for noise problems.

Hope this helps you a little bit.

A friend of mine is also having interference issues since he fitted an
automotive ignition plug conversion. His Yak 52 doesn't have a radio, but the
noise is over the standard Russian intercom.

He has changed the magnetos with a known good one but still no better.

Has anyone found a solution to this issue? He doesn't want to go back to the
old leads and I am going to be fitting a kit to mine once the Russian leads
die.

Two possible fixes which has been used in the past is; first, make absolutely certain the shielding on the P lead is in fact soldered properly to the P lead button, all the way around.  Second, you can try installing the following filter on each P lead.
http://www.aircraftspruce.com/catalog/elpages/lsMagFilter.php
Using the filter's mounting tab, you can mount the filter behind one of the nuts on the accessory case rear, circular plate. Essentially, there will be one filter at about the 10 o'clock position and one at the 2 o'clock position on the rear plate. The filter is installed in series to the P lead. Be sure to solder the shield again to the P lead button.

Excellent point about proper installation, also as Hans and Craig have pointed out.

The original Russian cables are 5mm thick. The modern ignition cables are
thicker, so you can¹t pull them thru the wiring harness.
Otherwise I would have kept it.

The modern plug cables also pass higher frequency components to the plug.
Therefore, more energy goes to the plug and you get a hotter spark.

As for the radio noise: a careful installation of a good radio could fix
that.
In EASA country, every Yak owner will have to replace the old Baklans or
other 25 kHz separated radio¹s with a modern 8.33 kHz separated model soon
(2017, I think).

I personally am very satisfied with Dennis¹ plug wiring solution. I have
done several installations of it but also often changed the Russian
radio¹s.

Years ago, I had a Russian Ziabrik radio on my 50. This was a terribly bad
radio, still 50 kHz separated.
So I changed it for a Briz (or something like that). Only a slight
improvement.

Then I installed a Becker 4201 on my noisy Yak 50 and it worked
flawlessly. But I also changed the whole radio wiring, inclusive
PTT-cables, antenna and antenna cables etc.
Today I have a 8.33 kHz Filser Funkwerk ATR833.

Still the 8mm spiro-wound plug wires + NGK plugs AND an electronic
ignition in place of the right mag (Mark Bitterlich¹s design).

Very hot sparks, 120 kiloJoules, and more than one spark each time
(capacitive discharge, multiple spark system).

Radio works perfectly, engine sparks perfectly too and has consistently
higher CHT¹s since the electronic ignition.
(at)Dennis: I installed colder NGK¹s, the BR7HS instead, => gives me more
equal CHT temperatures on my M14R 450 PS.

A suggestion from me is to re-wire original system with new wire style
cables. Its a Good reason why original system is completly shielded.
