Pappy, et. al.,
Regarding your post on AP pitch servo installation location we have
determined that the best place is actually under the radio rack area or
"baggage compartment" where you can mount the servo directly to support
frames for the old radio, and more importantly attach the control arm
directly to the bell crank. If you'd like pictures of an installation,
just let me know....

G'Day,
Does anyone have any spare magneto high tension insulated rods for sale for M14P?
This is the high tension lead the goes from the mag to the mag cap.
We have one mag US due to the insulation breakdown. Have made a new lead with high
tension wire, folded the wire over a small washer and soldered.
Am yet to try it.
If have part, please advise price and approx express post to Australia.
Thanks and cheers,

Hi Chris,
Pleased that worked out for you ... it's satisfying when the occasional long shot
pays off!
Just take care that the missing adapter isn't still floating around in avionics
bay somewhere, as that could really spoil your day if it works further aft.
Cheers, Rob

I will verify the size this afternoon and email you back. Last week I

Hi,
I am seeking any information on a spinner for a Yak 55M. I currently
have a spinner (an do not have gills) which needs to be replaced
(crack in the bulkhead), but I don't know where this spinner
originated from and it's not like the typical Yak 52 spinners I have
seen.
If anyone has a 55 with a spinner, can you provide any insight to what
I can use to replace this spinner?
Thanks,
Anthony.

| Subject: | Re: Prop Governor |
There appears to be some misconception regarding propellor and governor
operation and possibly some questionable practices being carried out as
a result.
The prop. hub assy. (whether Chinese, Russian, Polish, etc.) are
identical for operational considerations. They are all nominal 15 deg.
hubs which guarantee a minimum available pitch range of 15degs. Both the
Huosai and the M14P installations obtain a 15.5deg. range safely. Of
course the blade angle settings for each are quite different. Obviously
any change made to the fine pitch angle has made the same change to the
coarse pitch angle.
The specified angles for the M14P installation are 14.5 deg. +/_ 10 Min
(fine) and 30.0 deg. +/_ 20 Min (coarse) with the maximum difference
between blades not more than 10 Min. These angles have been determined
by the aircraft & engine manufacturers as the best compromise between
take-off, cruise performance and margins of safety in the event of pitch
control failure or engine failure.
The blade angle index mark set to "0" indicates the blades are set to
the correct angle. However that cannot guarantee they are within
tolerance limits.
NOTE to Roman: I should have advised you to check this setting to
determine if your blade angles are correctly set.
The governor (more accurately the CSU or constant speed unit) consists
of two units 1. a gear type oil pump that boosts engine oil pressure to
approx 230psi for propellor operation and 2. a fly-weight governor
that, with changing RPM, positions a pilot valve to control oil flow to
and from the prop. pitch change unit. The CSU both provides and controls
the motive power (oil pressure) for moving the blades toward fine pitch
and CONTROLS the motive power (blade counterweight force) moving the
blades toward coarse pitch. It does this by opening a single oil
gallery from the prop. either to governor oil pressure or to drain.
Therefore the propellor blade angle and engine RPM are directly
controlled by the governor, in both directions, at the RPM selected by
the pilot.
There is one very important exception. That is when the RPM control is
set to full minimum RPM. In this position the pilot valve is
mechanically lifted and retained to fully open the propellor gallery to
drain. The governor is out of the picture, the counterweights force the
oil to drain and move the blades to coarse pitch. This function is
called POSITIVE coarse pitch and directly relates to the safety
considerations for the coarse pitch blade angle.
In the event of engine failure you will want the blades at the highest
possible angle to reduce drag. If the engine is windmilling it will get
there much sooner if you go to positive coarse. In this case you want as
coarse as possible - feathered would be nice!
But, there is another failure mode to consider.
Here is the scenario;
You hear the engine RPM drop, the windshield is covered in oil and, if
you took the time to look, the manifold pressure is up. But you don't
have time to look. Your immediate action must be RPM control to positive
coarse. The prop.pitch change unit has failed, governor oil pressure
went to zero and the counterweights moved the blades to coarse. All the
governor knows is that RPM has dropped and it senses an underspeed
condition which it is trying desperately to correct by pumping all your
engine oil overboard.
Positive coarse pitch stops the bleeding and you still have an engine
that may get you to a safe landing albeit at greatly reduced power. In
this case you want a coarse pitch angle as FINE as possible to provide
enough power without over boosting your engine.
All the radial engines (using a single acting prop & governor) I am
familiar with use a propellor coarse pitch setting that provides about
1400 RPM in the positive coarse position. The M14P is no exception if
set up as the manufacturer intended..

Subject: Re: Yak-List: Re: Prop Governor
Roman, Gary in Las Vegas, I have had the same problem with my CJ, I
have a M14-P, So just last week I checked the blade angles, by looking
at the index marks on the hub, my blades were set at "0" on the hub
markings so I loosened the blade clamps and reset the blade angles to 2
index marks coarser giving me a higher blade angle. Your Governer is
working just fine, as it controls the high RPM, which it is doing at
100%. The blade angles in the hub, and the counter weights is what
controls the low RPM. When the blade angles are set too low of an angle
in the hub, as the airspeed increases the counter weights will go to the
high pitch stops trying to control the RPM, but when they reach the high
pitch travel stops, then the propeller becomes in a sense a fixed pitch
prop. and the RPM will increase as the airspeed increases. I am getting
100% 0n take off, and at 160 MPH indicated below 4500 ft, I can get it
to 64%, Manifold pressure setting 735 MM. ; At around 7000ft. I can
hold about 67%. I may set the angles ONE index coarser to see if I can
get a bit slower RPM, but if you do, check the High Rpm on take off as I
think that setting may be getting close to the limit for high pitch
setting to still be able to get 100% on the off..
Good Luck with the settings.. Let me knw how it works out for you...

Sorry... been away a couple days. Thanks for the feedback. I will try
the
suggestions. Mark, you do understand it correctly. And remember, it
cycles
fine on the ground. However, if I pull the throttle back to idle and
really
slow the speed down, the rpm will come back. To what I don't know. But
in
straight and level, pulling throttle back, it will not slow down UNTIL
speed
really bleeds off....like on landing. This goes along with what I meant
with it
acting like a fixed prop. Hope that's understandable.
To answer your questions, pretty much all of them are "yes". I haven't
touched
the prop governor. I took the entire prop, hub and all, off and shipped
it to
Jill. I didn't personally replace the blades. The only thing I question
is if I
had a little of this prior to recently. It has never come back to a
GOOD solid
cruise setting but, again, I don't cruise much if ever. I know it used
to come
back to very low 60's. It is MUCH worse now though and is very evident
... even
annoying. I agree with "where hands were last". That's why I wanted to
seek
advice before I went fooling around with the governor or elsewhere.
I know that on takeoff the power is right on 100%. I don't have much
room for
"sightseeing" on my strip during takeoff but I know it doesn't go over
100%. I
will fly this afternoon again and keep both at FULL forward in flight
and reply
back with an exact reading on that.
Thanks to all who are offering suggestions!!

Pappy, et. al.,
Regarding your post on AP pitch servo installation location we have
determined that the best place is actually under the radio rack area or
"baggage compartment" where you can mount the servo directly to support
frames for the old radio, and more importantly attach the control arm
directly to the bell crank. If you'd like pictures of an installation,
just let me know....
