Well I am not sure how Dynon does it, but here are what my thoughts were.
As it was mentioned rate gyros have to be integrated to get position and
have errors, thus they need to be reset.
So lets start the game on the ground, we turn the key on/master on. The
first thing we need to know is if the plane is level. Now the old mechanical
gyros would assume so, but I will bet Dynon doesn't. So the first step is to
measure the angle of the plane. There are two simple ways to do this one is
the magnometer which measures earth's magnetic field, however if you are
near a hanger this could be off. The second is an inclinometer, these
devices work similar to capacitive fuel level sensors. That is imagine you
have two level sensors in box with fluid. Now tilting box results in one
sensor reading higher then the other, thus you have a simple inclinometer.
Ok back to the problem so on the ground we will measure the pitch and roll
using two inclinometers. Now we can reset our rate gyros and life is good,
note we are assuming plane is upright which is a fair assumption on the
ground...
Now we take off and the rate gyros have errors in them so at some point we
need to reset them. Well if we assume that we still have the inclinometer
then we could reset them when the inclinometers are level. However this will
not work as that we could be in a banked turn which could throw the
inclinometers off. That is they could think plane is level when we are
really turning. For example a standard rate turn will throw the
inclinometers off.
So now we to know when we can reset the gyros, which will be basically when
we only have gravity vector (and lift hopefully) acting on the plane. So we
look at the gyros and say yes there is some error but does it say all forces
are zero, if so then it might be a good time to reset. Now if we also look
at our magnometer (aka compass sensors) and see if we have been flying
straight then we can be fairly sure it is a good time to reset. That is we
are not in a long banked turn.
Well this works well as long as we are upright, which is not a fair
assumption in the air. Therefore we need to have a sensor, a simple mercury
switch that tells us if we are upright are not. Actually the inclinometers
may have this feature included.
Well this would work quite well depending on the error rate of the gyros,
well if we also had the velocity of the plane we could compensate for some
of the gyro errors. That is if we know we are going 100knts and turning we
can get an idea of what the gyros should read. So lets add air speed into
the mix as well.
Now we have all this data coming in and we want to process it to give
results, and we would like to have a "continuous" reset feature of the
gyros. To do this we take all the inputs we have:
3-axis rate Gyros
Inclinometers
3-axis Magnometers (aka magnetic field sensors)
Mercury switch (inverted sensor)
Air speed
Then we derive equations for our outputs, then we apply these equations
using a signal processing method called a Kalman filter. This will basically
keep the system reset all the time and provide us with our outputs. We also
add some sanity checks to see if the data is in left field and basically
ship the product. That is the magic is actually in the filtering algorithm
for the data.
Now I am not in any way associated with Dynon so this is just a guess. I
would also guess that they use temperature inside their box as well to
compensate the gyros but again this is only a WAG.
If someone wants to pay me to do it I will even make an attempt to see if
this system would actually work. :)

No problem Stein,
In fact, you may have made my day. Looking at my engine mount it does look
like it is only the nose gear mount that gets in the way. I was thinking that
it wouldn't work on any RV.
I am 60 years old, and a fairly low time pilot with no tail dragger time.
When the decision had to be made, I just didn't feel like taking on the risk of
ground loops, etc., along with the performance of an RV. Maybe next time!

Yes, BUT! Tail wheels are known to shimmy. Tail wheels are known to damage
the rudder. Tailwheels also ground loop a bunch easier. AND I own a

Hi Dave:
The value really depends on the condition of the crankshaft and
unfortunately this can only be determined at teardown. I have purchased
engines like this in the past but only on the basis that the owner guarantee
the crank is serviceable.

I was asked to pose this question by a friend who does not go on-line. Reworking
the exhaust system on his airplane, he wants to know the optimum torque value
applied to exhaust stud nuts on an 0-320 when using crush gaskets. He says Lycoming
will not provide this specific information referring him to the exhaust
system manufacturer (which has proved unsucessful) and AC43 merely provides
a generic torque value that most people simply refer to.
This gentleman is a retired flight test engineer and tends to obsess. I said I
would pose the question on forums such as this one and see what I could come
up with. What information can I relay to him?

--> RV-List message posted by: Hopperdhh@aol.com
Very good reply Glen. I would like to add a few things. I just finished my
RV-9 replacement rudder for my early RV-7A.
1. Be sure to trim the stiffeners enough that they don't touch the opposite
skin near the trailing edge. This will be automatic if you draw your line
toward the center of the marker holes.
2. Use a 30 degree triangle (drafting type) to set the forward angles --
although not critical.
3. As was posted earlier, round the corners with a file until the marker
holes disappear.
4. Use Pro-Seal on the trailing edge, let it cure plenty long. AND
alternate rivet directions to keep the trailing edge straight. I didn't use Pro-Seal
and my trailing edge is "wavy." Alternating rivet directions kept this from
becoming a big curve though! But, I think Pro-Seal would have kept the
aluminum from opening up at the trailing edge. It's also possible that I countersunk
too much.
5. Just before you close up the trailing edge use some Pro-Seal to "glue"
the left and right stiffeners together. This will prevent the skin from
cracking which was a problem on some RV-6s.
I'm definitely not an expert, but this is what I wish I had done. I will do
it better next time!
Hope all this helps you get a good job. Take your time.

BREAKING NEWS
SECOND SUCCESSFUL ROCKET-POWERED FLIGHT FOR AMERICAN SPACESHIPONE TEAM:
Hot on the heels of receiving it's FAA licence, the American SpaceShipOne
team had a perfect rocket-powered flight today, April 8, reaching an altitude
of 105,000 ft.
Behind the controls of SpaceShipOne's second successful powered flight
was pilot and future astronaut, Peter Siebold.
The engine burned for 40 seconds and reached a speed of approximately
Mach 2, making it the first privately built space vehicle to accomplish this
feat.
"105,000 feet down, 223,000 feet to go!" exclaimed an excited onlooker,
as he watched the ship fly overhead.

On my 4 I just started with a wedge of balsa wood, attached with two sided
tape. Started long...cut progressively to the right length and then painted
to match the rudder. Stays on with the double sided tape. I have mine
below the horizontal stab, and although it might not be as effective there
it is much less noticeable.

is a link to the D-10 OAT installation I have done, it includes a link to a
spreadsheet showing the data from tests at 3500, 5500, 7500, and 9500 ft TAS
vs IAS Vans steam gauge vs D-10 with OAT/TAS/DA.
I installed mine in the inspection panel behind the aoa/pitot, so the wire
length was ok since my EDC-010 is in the wing leading edge.
Although this was done with a test version of their software, the latest
build, 1.09.00 includes these features.
I have also proved that the RV-6 side mounted NACA vent OAT is about four to
five degrees hotter than the wing OAT. They are both equal on the ground,
but differ in cruise flight.

Mark,
I hung the two coils on the engine mount using adel clamps. This required
longer leads which Klaus made up for free (exchange). It's pretty straight
forward but I can send pics if you like.

--> RV-List message posted by: JEREMY C ROBINSON <k2akwjere@juno.com>
Request a recommendation for/against Tom Waters, AIR-TEC INC,
Orlando, FL.
I am finishing up RV-6 kit # 23833 originally bought and started by
another builder.
He purchased an AIR-TEC engine in 1998 which I have installed in
the RV-6. It is a 160HP fuel injected Lycoming O-320. It has an
O-360 crankcase with O-320 cylinders.
Questions:
1. In 1998 was there a shortage of O-320 crankcases? In your
opinion, does it add or subtract anything using an O-360 crankcase?
2. What has been your experience with AIR-TEC engines, good
or bad?

This is really quite simple folks,
up there in Washington there is a small hole that goes to the very center of
the universe. They have installed a small, unobtrusive wire to the very
center of the universe with an all sensing relative spatial sensor that
transmits to the other end of the wire where there is an oriented magic
node.
Then its a simple matter of installing another uniquely tuned oriented magic
node in the back of each unit that receives the data relative to the center
of the universe through the hyper space time continuum. Then the rest of the
parts just calculate the Earth's relative orientation to that of the center
of the universe and display that all on the screen in a nice format that's
easy for us dumb pilots to interpret. And because all the magic nodes are of
the spherically oriented type it doesn't matter where you are relative to
the mother magic node (ie upside down on the south pole or right side up on
the north pole).
Now the beauty of this is that once our RV's get pressurization and rocket
engines we will be able to use our D-10s in space.
Now that wasn't so hard to understand.

Hmmmmmm!! Would that be the same black hole that all your tax money
disapears into?
Up here in Canada our Black hole is not at all that small.
Could it be that yours would be smaller due to this modern age of technology
what with "all sensing relative spatial sensors and magic nodes" and stuff
like that. WOW what will they think of next?!!! {[g-)
keep the good stuff coming Wheeler,

Reworking the exhaust system on his airplane, he wants to know the optimum
torque value applied to exhaust stud nuts on an 0-320 when using crush
gaskets. He says Lycoming will not provide this specific information
referring him to the exhaust system manufacturer (which has proved
unsucessful) and AC43 merely provides a generic torque value that most
people simply refer to.

I have an O-320E2A in my -4 and it's only 150 HP. I'd like it to be 160 but
I heard the bearings won't take the high compression pistons. If this can
be done would you ask your friend if he knows how they got 160 hp. out of
his E2A so I can get it out of mine?

Listers,
Although I saw no mention of it in the plans, do we need to be sealing the vent
line, fuel pickup, and fuel drain fittings somehow? I saw in the archives that
some sealed them with proseal, but others said they would never come apart
if that was done. Is FUel lube the right thing to use? If so, which fittings
should this go on? This seems like great info for the instructions.
Thanks,
Scott

===================================
Rick-
IMO, there really is no one optimum torque value one could state, considering
the variables (exhaust system flange strength, gasket crush force required
and such). You obviously want a torque that doesn't cause distress to the
flange or studs (5/16", IIRC). Tony Bingelis in his book "ON ENGINES" recommends
a
torque range of 160 to 180 lb-in (13 to 15 lb-ft) but I have a range of 100
to 140 lb-in (8 to 12 lb-ft) listed in my POH, and I got that from somewhere
else (maybe Larry Vetterman's instructions).
I would try around 10 lb-ft to start, then inspect for leaks and retorque
after 10 or so hours at operational temps.

Jeremy,
If this is the same AIR-TEC from Florida that sold me an engine about 10
years ago I suggest extreme caution. The engine I purchased was represented
to be 200 HP and overhauled with new cylinders & internals(
pistons,rings,valves,springs, etc.) and the lower end rebuilt to overhaul
standards. The engine I received looked good to my uneducated eye on receipt
but I was concerned in that there was no Data plate and the log book
contained only one entry to the effect that the engine was rebuilt for an
experimental aircraft. An A&P friend removed one cylinder to inspect and
found old parts bead blasted to look new and reinstalled. The cylinder bore
was miked and found to be worn and just passable. My friend called the
engine" a paint can overhaul".I contacted Lycoming with the serial number
which was still readable and they advised it was 180 HP.The FAA advised the
log book with the one line entry was not in violation since the engine was
for Experimental use.
My lawyer advised I had a good case but that action would have to be brought
in Florida and that the legal bill could be in excess of the engine cost.
Luck was with me in one regard. Air-Tec , at my request, put all their
initial representations and offers in a letter sent via Snail Mail. The USPS
advised that the situation described could be Mail Fraud and to send the
case to them.
I contacted Air-Tec and outlined the above and they agreed to a full refund.
The gent I corresponded with was a Dick Waters at Air-Tec.
Alls well that ends well so they say but I had a rough few months. I suggest
caution .

Fun is the filtered air box!
The length of the FAB is determined by the ability to get the lower cowl
on and off, right? But I can't go too short, or there will be no room
for the carb heat door, right? The plans say 16.5" to start, but that
looks to be too long. It's best to have the prop on for a true cowl
on/off test, right?
Thanks,

This Brings up a good point....
You can slap the 160hp pistons in most any O-320, and many people have with
no problems, but -
1) The narrow deck cases that aren't using hold-down plates have been known
to crack at the cylinder bases with the higher compression pistons. You
can't simply just "add" hold down plates to a narrow deck engine that didn't
originally use them without putting longer thru-bolts(-360 ones) in the
case.
2) The main bearings didn't change much in the cases, but the nose and
flange bearings are a bit beefier in the original 160hp ones.
3) Most of the wide deck engines have no worries about throwing in the 160hp
pistons (which are standard -360 pistons).
So, it's very feasable to get 160hp out of most any old -320 (and it's been
done to most every series), but that doesn't necessarily mean it's a great
idea! FYI, I know an engine builder who does some racing engines for the
"fast glass" crowd, and has done a number of -320's that dyno'd at
190-200hp, and -360's with 230-250hp!! These engines get into radical cam
grinding, different lifters, over 10:1 pistons, ported and flowed heads,
etc...I wouldn't want to guess about the TBO though! I've personally seen
one of those engines running 10.5:1 pistons with the cylinder blown clean
off the engine!
