18mm gasket probes were included, the Dynon D-180 just showed up one day without
an invoice so I don't know who produced the probes (they were in white boxes
with Traditional Mandarin characters I could not read.) Dynon suggested I shorten
the Stein EMS leads to allow more accurate readings--as it turns out, the
"open" lead problem was solved when I did that. It took me a day of the Dynon
refusing the firmware update to even consider that the 'factory' harness
could be faulty, and the better part of the next morning to find out which two
wires Stein had flipped on the EFIS harness. The EMS leads were about 3' too
long. Don't shorten the gasket probe leads! (The EGT probes were bayonet-type.)

I sent mine back because after power on, it would roll inverted for a few
seconds before righting itself. Factory said send it in.
I have flown my 601 approx 2.5 hours when I determined the engine was having
minor problems. So I figured while the engine was down, I might as well
send the Dynon in during the down time.
My O-200 has new ECI cylinders and they have the holes for the CHT probes.

Wellllllll, now I have to tell you this embarrassing story:
Some time ago I bought 6 pieces of aluminum 6061-T6 extrusion
(1"x1"x0.125"), to be used on the spars.
All but one of these pieces had printed the mill's specifications on them
(alloy, dimensions, mill name...).
While at the time I trusted the vendor was selling me the material I
ordered, later I became disappointed with their services. I am now concerned
about the composition of the unlabeled extrusion.
Further, the parts have been primed and assembled (as in "riveted"), so I
don't know which one is the "suspect". I need to verify the six of them to
be sure.
The alternative is to trash the spars, which includes disassembling a
partially riveted outboard wing.
As you see, the lab test is expensive, but it is the cheaper (effort-wise)
alternative at hand.

Hi,
In a recent message it was reported that retensioning of cables was
necessary after one year. That is odd and should not happen.
For the rudder cables of the tricycle versions,
such retensioning should be done with caution. The reason is the bungee
chord of the nosegear.
When the plane is on the ground, then the nosegear pushes up the bungee
and thus the tubes to which the the steering rods are attached,
are not at the stop.
Now the tension of the rudder cables is maximum when these tubes are
at the stop, and full tension is
imposed only when the plane is in the air. This fact mandates that the
tension of rudder cables is measured only when the nosegear is unloaded,
say using a jack,
and thus the situation in flight is simulated. Otherwise the cable
tension in flight may be excessive.
As for my plane, after 12 years, we have never retensioned the cables.
Happy flying,
Klaus

Carlos,
I'd order another piece from them, requesting certification of the
6061-T6 pieces sent and test what they send you.
Test against the known values for 6061-T6. That's as close as it gets.

But Larry, how would that prove that all the material I bought from them in
the past - and are now part of my spars - are actually 6061-T6?
What I am suggesting is that, when I bought them, someone in the warehouse
pulled one extrusion out of the wrong shelf. (Of course I am hoping it is
simply an honest-to-goodness piece of 6061-T6, just unlabeled).
The only way to make sure is to cut samples form the extrusions and testing
them (BTW, I got clearance from ZAC for cutting samples with these
dimensions from the spars).
Thanks for the input

As a suggestion based on my AF-3400 screens from Advanced Flight
Systems, I plan to dim them to the least brightness that allows them to
be easily read in the conditions of any given flight. In other words,
just as you would not drive you car or truck with the accelerator
constantly mashed to the floorboard, there is no reason that you would
have to always run the screen as bright as its maximum allows. The
benefit of dimming a bit would be longer screen life(?) and lower power
consumption. On the other hand, just like the bigger engine in my car, I
like knowing that it is there when needed if only rarely and briefly.

100% antifreeze will not cool worth a darn. Of course you are posting ab
out oil temps but on a watercooled motor thses numbers do interconnect.
On my watercooled 801 I run 50/50 in the winter and during to summer dra
in out as much of that mixture and add straight distilled water. There i
s still a slight amount of antifreeze in suspension to add lubricity to
help the water pump seal. If I leave the 50/50 set up in during the hot
summer I gain about 15 degrees f in water temp over the distilled versio
n. I also have found my relationship with water temp v oil temp works ou
t to somewhere around for every 5 degrees of additional water temp the o
il gains 10 degrees f.
YMMV

If the backlight is using white LEDs (and not a compact fluorescent lamp

actual liquid crystal panel in not impacted by the brightness.
Battery life is a different story.

Glad we settled that... that extra heat does not effect the screen at all? Cool.
Touch a 400 nit screen after 3 hours of use and then touch a 800 nit after
3 hours of use. Not cool. That extra power draw is turned into heat and light.
The case is the same, the heat goes somewhere and does something.

Ladies & Gentlemen,
I have just received our first 4340 billet crankshaft!
I am proud to say that the workmanship and the finish are top notch and the dimensions
are all perfect.
Our next step is to send a material sample to an independent laboratory for a material
analysis. This will confirm the alloy and the quality of the alloy.
Assuming it passes the laboratory tests we will have the strongest Corvair crankshaft
available any where!
Here is a picture of the Crankshaft.

Carlos,
I had a friend in a similar situation.
Fortunately he is a structural engineer at the navy ship yard and had access to
all of the facilities assets in this discipline.
The test that he settled on was a hardness test.
His thinking was that if the aluminum was not 6061 t6 it was a 3xxx series and
would be way off. so using a known 6061 t6 sample he got a base line measurement
and then tested the suspect sample.
He was surprised to find that not only was he correct in his theory but also that
the difference is staggering!
I have been able to simulate this test with out the expensive machinery by using
an automatic center punch. Punch a piece of 6061 T6 and notice the divot left
by the tool. Then punch the sample you suspect. If there is no noticeable difference
the chances are excellent that you have the same alloy.
If you have a substandard alloy the divot will be noticeably deeper.
Obviously this method is not completely accurate or totally reliable but it is
enough to tell you if you are with in the extremes.
Hope this helps,
Brady

Terry,
I think you might want to know what the cable tensions and hinge play are also.

"plastic substrate based displays"
I think if you check the panels used in the Dynons (along with other flight
gear and most consumer equipment) are glass-based.
But anyway, the article writes about "environmental conditions". I won't
deny that higher temperatures correlate with increased failures. But how
high and from what heat source? If the Garmin 496 specs are to believed they
are happy to have you operate it up to an ambient temperature of 170F (too
hot to touch). And if it is like a lot of active matrix color displays (like
the one in my Palm Treo when I leave it on the dash of my car in the sun) it
doesn't have a hard failure at elevated temperatures - it simply becomes
unreadable. Let it cool and it works fine again.
Here is a link to a flier on Sharp's LCD displays:
http://sharp-world.com/products/device/catalog/pdf/ia_lcd200802_e.pdf
On pages 11 and 12 (as Acrobat sees it or marked as "19" through "22") there
is a column headed "Operating Temperature". Two kinds of temperatures are
listed: "ambient" and "panel surface" in centigrade. Listed high ambient
values range from 40 C to 65 C. The upper limit of panel surface temperature
ranges between 70 C and 85 C (again too hot to touch). And this is without
even selecting for panels designed for harsh environments.
If you google "active matrix mtbf" you find figures in 10 of thousands of
hours. And many of those hits specifically cite this as the MTBF of the
backlight. Even assuming you are on the wrong side of the bell-shaped curve
you are still going to put a few engines in your plane before the LCD in
your panel fails.
Look at it from a practical business point of view (end-customers, Dynon and
their panel supplier). The designers say "we can build you a brighter panel
but you will see more customer returns". Who in the supply chain would want
such a product?

Craig, instead of tying up this list with speculation, why don't you come up with
the data you have, I will see what design/longevity/failure data/info is publicly
available from CASA as to their "approval" of Dynon equipment in Australia
and we can talk about it at the Zenith dinner on the evening of 7/31?
P.S. I have a feeling the D180 will be a little bit down on the pecking order as
to issues the attendees will be talking about.

Sadly, I'm going to miss the dinner as I'll only be at OSH Monday and
Tuesday. Since I won't be seeing anyone I'll state for the record that I am
6 foot 4 and surreally handsome ;-)
But I'll check with another source which you can interview too. Rainier
Lamers is the head and chief designer at MGL Avionics - makers of the Enigma
(5.7" diagonal), Voyager (8.4") and Odyssey (10.4") color glass EFIS systems
- with some of the largest, brightest displays in this area. The Enigma Mark
II is going to offer 1800 nits while the Voyager's display is rated at 1200
nits (although I believe everyone lies about nits). You can read Rainier's
postings on these specs at the MGL User Group on Yahoo:
http://groups.yahoo.com/group/stratomaster_users_group/
Anyway MGL is based outside of Cape Town, South Africa so Rainier doesn't
attend OSH that often. But he will be manning MGL's booth (at least some of
the time) this year. Rainier is unbelievably open about his products and
development plans. Google the "osborne effect" to see why this is at the
other end of the risk spectrum from say Dynon. Anyway drop by booths 2139
and 2140 in hanger B and talk with Rainier - everyone. I think you will
learn a lot.
I'll ask Rainier about the relationship of display brightness, reliability
and MTBF on the Yahoo group and see what he says. Someone else can ask the
same question on the Dynon-owned forum.

Full disclosure: I own an Enigma and started the user group but I have no
financial interest in MGL.

The key here is that the case and electronics were designed for 400 nits and a
maximum temp of 122 F.
I am sure Mr. Lamers could design a panel that would put out 2000 nits for 20 years
at 170F ambient. That is not the question.
The rub here is: What is the effect on longevity of the D180 as a whole when you
double the nits without redesigning the case, the cooling, the other components
inside? Especially where such a low ambient temperature was speced in the
first place.
You can attend Women Soar on Monday and Tuesday if you want! You will find me
hanging out with the RRL guys Tuesday afternoon.
It would be a pleasure to meet you.

In that case it is a question that can't be answered by looking at panel
specs in isolation. Only Dynon can answer it. I guess we would need an
official response to resolve the conflicting unofficial responses.

I may not make it. But I'll see if my ugly brother can.
