| Subject: | FW: Magneto and Air Distributor timing |
I thought I might throw a small pebble into the seemingly now-tranquil
waters of magneto discussion!
What is not always known is that while all M9F magnetos have exactly the
same timing, there are actually six
different models of the M9-35M, and all with slightly different timing.
These variants are identified by a number
which is stamped onto the outside of the magneto case, and the timing
for
the different variants is given in the
table below.

Hello Richard
Thank you for this table..
This is incredibly usefull data when needed.
Impossible to find otherwise.
Great thanks for sharing.

I hope that Matt will allow me a little bit of advertising!
We have known for a number of years that the original Russian coils are
failing and indeed in Europe have had several forced landings as result of
this. We consulted with a UK company who overhaul magnetos for historic
racing cars who felt that the main problem was that the capacitor, an
important part of the coil sits inside the coil of hotwire and over a period
of time through a combination of age and heat will slowly degrade until it
fails, and even if it is only in one magneto, the symptoms are a total, if
momentary stoppage. Over a period of time this will get worse until the
engine will stop for a significant period.
Working with this company we developed, some 30 months ago, a new coil with
a high-technology Panasonic capacitor bonded to the outside of the coil, as
well as improvements to the materials used. These have been very successful,
but this small company could not produce sufficient coils for us. Then, UK
CAA realise that we were selling coils, but without any paperwork - this
being deliberate. Of course we do not have the freedoms that you lucky guys
have in the USA, and they began grounding various perfectly airworthy
aircraft belonging to our customers. And at the same time, they asked us
(quite nicely) if we could make a formal application to certify the coils.
I had absolutely no idea of the amount of bureaucracy and testing that this
would involve - but I suspect it would be the same if one wanted to get full
certification for a new coil with the FAA! Before this, we had also decided
to investigate a larger capacity manufacturing unit, and came to an
agreement with AYC Ltd in China. They are one of the largest oil
manufacturers in the world; making over 1 million a year, ranging from
lawnmowers up to Ferrari cars. Although we represent incredibly small
business in their terms, they were extremely enthusiastic about getting into
the aviation business. We have found them superb partners; technically
incredibly capable and very responsive. So it has been the AYC coils that
went through this testing process for certification, and through the use of
much better materials, these coils give a spark that is 15% to 20% stronger
than a perfect Russian coil, and we now have them in full production.
Importantly we now have full certification from UK CAA and EASA who control
all aviation in Europe, which must be an indication of quality!
Please contact us if you need any more information about these coils.
