My bad [Embarassed]
Yak-52 M-14P.
Thank you to those who responded, that will help.
Ttail, that is a big difference between the pods. Am I reading it correctly? The
one with arrow (7) is 199deg C and the others thus higher?
What is the highest? Can't make it out on the photo.
What I noticed on the last flight and I am not sure whether I am imagining things,
but it felt like the cockpit was warmer than normal, after stopping engine
and climbing out and walking around the YAK, that the left as standing in front
of the plane is warmer than the left.
Is that normal?
That is why I thought I'd like to check the temperature probes, where they are,
etc.
If it is measuring the coolest cylinder, some of the others may become very hot
indeed even if the coolest is still in spec on the CHT gauge.
I don't have a monitor system to measure each cylinder. Pretty much a stock YAK.
What I also found is that it is smoking a bit while on idle even after flight from
righthand side exhaust plus the righthand side exhaust have a little oil on
the outside which come from between the most bottom piece and the next one up,
ie most bottom joint. But it doesn't look like the normal oil that is black
and drip out of the exhaust when stationary, so it could be smoke system oil,
but I somehow doubt it. Smoke system off and still oil doesn't seem possible.
AMO reckons rings might need to be replaced.

BTW, there is a long-wing Yak 55 in Illinois which is currently listed for sale
on Barnstormers. It was previously based in Europe, where it had some decent
competition results in both the Intermediate and Advanced categories.

Thanks for the heads up on the Illinois long wing. Last week I was in touch with
the seller. I'll be back in the States tomorrow, and hope to work out a time
to go see it next week. There is an M out in Oregon that I'm interested in as
well. That's why I was looking for impressions from people who have time in both.
I really like the way the M flys, but what if I like the 55 better? With
a nice example of each type out there, it just seems like its a sign from the
Gods!

Yes, both the Oregon and Illinois planes would be worth looking at. I suspect
additional 55/55M's will come on the market this winter. Earlier this year there
were 3 or 4 listed for sale at the same time. There was one in western TN
that I was interested in, but it sold before I was able to get out and take a
look. Good luck.

| Subject: | Re: Yak 55M vs Yak 55 |
Please let me start by saying my interest in acro predates my doing acro by a long
time. The interest started in music, ballet, figure skating, and flying for
the Navy. But I did own a long wing for ten years, and she was my love.
Like skating, all acro routines start with 100 and lose points there after. We
all strive for 100, but how can we measure it from the ground?
The ideal is a machine that combines power, agility, and gives the pilot the possibility
of adding grace to achieve winning scores, no?
But grace is subjective, and scores are not.
Having owned a 55, I have known the grace, and traced the accuracy possible via
smoke, of what they can do. I know a 55m or a Su26 have their own. They support
support faster everything, and that may be important.
But I fear that scores have become primary, and worry that grace has suffered.
For people that attend ballet, the analogy is clear.
Imagine a brick, a flying brick. Something with remarkable spin, climb characteristics.
Something that could trace out Aresti curves in 3D with complete fidelity.
Is that what we want to pilot? The community sets categories, sportsman,
intermediate, etc., but i don't know if it is possible to include the subjective
into the categorization process.
Fencing, saber fencing, has also endured a debate between form and scores. I left
that scene years ago and don't know the outcome, but the argument is similar
in that some things score, but are ugly. Who can judge ugly, yet we recognize
it when we see it.
I suspect the future of aerobatics lies in the use of drones to show what happens
when a pilot and his mount, are one. Besides the tracing of 3D curves, future
scoring systems may also include a factor for artistry or whatever. None
of these ramblings are new ...
So back to the issue, and thank you for allowing the preceding digression:
Know what your machine can do - and design your program accordingly ...
For me, the ballet capabilities of my 55 outweighed the scoring potential of other
machines.
She still is in my dreams!
Best wishes for straight lines, and calm winds.
