Scott, we have a 55 with the original cooler ducting, I could take pics for
you next time its out the hangar. Let me know.
Sights, we could make these also but you wont like what's happened to the
USD vs the GBP, again a picture may help you.
In the cooler months 50% covering of the cooler is the norm in the UK
whatever the YAK type.
Cheers, MJ

Does anyone have pictures showing what the doors/louvers at the front/rear
of the oil cooler on a Yak 55 look like. Mine has none and its going to be
getting cold soon in the Northeast and I am curious what was originally
mounted. Duct tape for now but I would like to also know if what was
originally in place is available anywhere.
Also, any recommendations on aerobatic wingtip sights, mounting, sources,
experiences etc.
Thanks, Scott

This year we have had to B530 TA D35 propeller blades (on different props)
written of due to water ingress. Water entered at the leading edge between
the guard and the blade, this caused the wood to swell.
If you have the opportunity to use the Hoffmann leading edge do, it will
alleviate this type of problem.
Now winter is coming I strongly recommend that propeller covers are used. If
not water will get under the leading edges and then freeze lifting the
surface, them more water can get in etc.

My only concern would be for the oil to cool too much and congeal in
the cooler. At that point you would end up with a high oil temp
problem even in the middle of winter. (Actually, the middle of winter
would be when the problem would happen.) You still want to make sure
you do your winterization to reduce cooling air flow through the oil
cooler in winter. Multi-vis oil with a low temp pour-point below
ambient temps will help too.

SECOND AIR ACES PLANE LOST
A Texas air-combat simulation and upset-recovery training center has
temporarily suspended operations after losing a second aircraft in just over
a year to an apparent wing separation. The Texas Air Aces T-34 went down
Tuesday about three miles from where a similar aircraft crashed on Nov. 19,
2003. In both crashes, the two people aboard the aircraft were killed. And
in both tragedies, witnesses reported seeing one of the wings snap off
before the aircraft spiraled into the ground near Lake Conroe.
...THIRD IN FIVE YEARS
A similar crash in Georgia in 1999 prompted an Airworthiness Directive (AD)
requiring thorough periodic inspections of the wing spars on T-34s. After
the AD was issued, several alternative methods of compliance (AMOCs) were
approved. After the 2003 crash, the FAA's preliminary report suggested that
the aircraft wasn't in compliance with the AD, but FAA preliminary reports
can be wrong. The FAA report on Tuesday's crash incorrectly identified the
aircraft as a Beechjet (hopefully this has since been corrected) and also
says only the pilot was on board. Texas Air Aces spokesman Dave Hollaway
told the Houston Chronicle he didn't know if the aircraft was in compliance
with the AD.
Always Yakin,
Doug Sapp

I have experienced carb ice on my M14 powered CJ6.
On Canada's west coast at this time of year we quite often experience high
humidity with temperatures hovering around freezing,
I kept the CJ6 warming horns which seem to work well showing a good temp
rise with carb heat selection.

| Subject: | Yak 55 Oil Cooler |
--> Yak-List message posted by: "Doug Sapp" <rvfltd@televar.com>
My 5 cents worth:
If the temp by pass operates the way I think it does there is a possibility
(on a cold day) for the valve to bypass the cooler for long enough time for
the oil to congeal in the cooler, then the engine oil temp increases and the
valve opens, forcing hot oil into the cooler and a wad of the congealed oil
into the line, the pressure builds in the oil cooler and if the oil is thick
enough, the oil cooler pops like a overripe tomato.
Always Yakin,
Doug Sapp

SNF Troops,
Good news, *almost* everything will be the same for next
years Sun n Fun except the EAA name will be missing. WOA
will be there but maybe with slightly different ground
pounders and airshow changes. See below message.
I have LOTS of rooms on hold at Zephryhills (ZPH). I'll post
tel numbers after the holidays. Expect to have a good time!
Great facilities, only a 35 min drive from LAL, at good
prices too. Can't beat that!
Craig Payne
December, 2004
Dear Warbird Enthusiast,
As many old timers will remember, Sun N Fun began
as a small event, under the banner of EAA. As Sun N Fun
has grown, they have become more self sufficient and
independent. As of this year, they will assume full
responsibility for all aircraft flight and ground operations
including those related to Warbirds. We will be going back
to Sun N Fun as EAA Warbirds of America and we will
be organizing the activities that we have always done there.
(social, hotel arrangements, judging, awards banquet, etc.)
The activities we will no longer be controlling will be
ground operations (flight line) and the airshow for which
Sun N Fun will be responsible. I would urge all of the
flight line and airshow volunteers to become Sun N Fun
volunteers. Everything we always did in relation to
aircraft operations will now be under the Sun N Fun
banner instead of the EAA banner at Lakeland. This
will not have any effect on anything we do at Oshkosh or any
other EAA Warbirds of America event anywhere else. As an
organization, EAA Warbirds of America will give our full
support to the Sun N Fun event and we are planning to
have a great time. All of the support that warbirds
received from Sun N Fun will continue as before.
The Leeward fly out will take place on Friday this year and
Jimmy Leeward plans to make it an expanded event with busses
available to take interested members out to the nearby Drag
Race Museum. There will be no warbird airshow on Friday so
there will not be any pressure to try to get back early to
fly the show. There will be an aerobatic box available and
time can be put aside for formation flying as well. We will
have our awards banquet on Saturday night, April 16, at
Kermit Weeks Fantasy of Flight Museum in Polk City.
From myself, the Warbird board of directors, and Bill
Fischer, our Executive Director, have a great end of the
year holiday and keep em flying.
Sincerely,
Michael Schloss, President
EAA Warbirds of America
3000 Poberezny Road
Oshkosh, WI 54903-3086

I have a Yak 55M, and it does not have carb heat. Anybody know why...just
curious, as the Yak 52 evidently does.
