Subject: Yak-List: oil additives
Reminds of back in the late sixties (68?). Graham Hill was asked if he
thought using STP (car sponsor) at the Indy 500 (he won that year) was
beneficial. His response: "It doesn't seem to hurt anything and they pay
us a lot of money to put their logo on the car, so we use it."

I have a number of Yk-55 wing sights available from stock. This particular
type is shown in Herbs pictures of G-YKSS and in the pictured number c-4.
Additional pictures are available through the following links
http://nelsonit.net/~rob/55_sight.jpg for a picture of the sight itself
http://nelsonit.net/~rob/55_sight_1.jpg for a picture of these sights fitted
on G-NOIZ Yk-55M
http://nelsonit.net/~rob/55_sight_2.jpg and
http://nelsonit.net/~rob/55_sight_3.jpg for pictures of the attachments
I have several of these in stock, if anyone is interested, please contact me
for details.

Subject: Yak-List: SIghting guage and Yak 55
Here is link to a few photos of a variety of designs.
I would also put a small streamer on the design for tailslides,
torque rolls, and any other maneuvers that are in reverse.
I also included an article that I found by accident comparing the 55
to a Sukhoi. I had searched for info on 55s and never found this
one. I had seen the review by Allan Cassidy before.
The page also has some old videos - 3 years old. I have some new
video of inverted spins and tumbles in the 52. I'll try to post in
the next few weeks.

Oil Additives
Referring to Brian Lloyd's posting, I am not an oil specialist, but was
wondering if Shell and Co. accept an INLET oil temperature of 120=B0C -
i.e. a maximum temperature of possibly over 160=B0C. Is that really the
case?
I am no defender of Russian oils, but the temperature for Yaks and
Sukhois is of course INLET temperature - that is oil that has gone
through the oil cooler; back into an oil tank and then now going back
into the engine.
This cannot be compared with sump temperature on "wet-sump" engines.

| Subject: | Red Stars has arrived |
This past weekend I was leading our Red Stars Team at the Pease AFB
show. The tower was coordinating each act's clearance into the airspace
(a screwed up way to run a show, BTW).
In the middle of our performance the tower asked me how much longer
before we're done. After I gave him the time we needed to finish, he
then told the inbound B-2 bomber that he'd have to hold and wait for the
Red Stars to finish.
I think we're no longer the redheaded step-child when they put a B-2 in
a holding pattern until we finish!!
Interesting side note: that one B-2 was doing a fly-by at FIVE airshows
that day! Hope it's got a good port-a-potty.

Such a tragic ending for such a stupid problem.
Be safe and check that seat belt.

Yes. I spent time talking to one of the aviation oil engineers at
Shell about just this subject. He assured me that their standard is
oil *inlet* temperature as that is what is measured on Continental
and Lycoming horizontally-opposed engines. The oil temp is measured
at the screen/filter after the oil pump but before the oil enters the
engine's oil galleys. I pressed him specifically on this issue and he
concluded that what is measured in Lycoming/Continental horizontally-
opposed engines is indeed what we call oil inlet temperature. It is
the temperature of the oil as it enters the engine and before the
engine has a chance to transfer

Uh, please explain why not? The engineer from Shell certainly thought
it could and so do I. From the point of view of the engine you have
the oil that is pumped into the galleys (inlet) and the oil that
returns to the sump (outlet). In the radial engines there are two oil
pumps: a scavenge pump that picks up the oil from the sump and pumps
it to the oil cooler and a pressure oil pump that takes the oil from
the cooler and pumps it to the oil galleys. In a Lycoming or
Continental there is only one oil pump but it performs both
functions. It scavenges the oil from the sump and sends it to the oil
cooler but since this is a more compact system, there is no second
oil pump that pumps the oil into the galleys. The oil from the cooler
then goes directly to the oil galleys.
Regardless, the inlet oil temp on our radial engines and the oil temp
in our horizontally-opposed engines are measured at the same place:
just before the oil enters the oil galleys headed for the bearings.
