--> RV-List message posted by: "Jim Jewell" <jjewell@telus.net>
Hi Paul,
My way:
In order to assure that the bearings inner races and spacers etc are fitted
mechanically tight, excess grease must be squeezed away from between the
various parts. To do this it is necessary to first over tighten them
somewhat.
Turn the axel nut by hand until snug, rotate the wheel. Then use a wrench or
some channel lock type pliers to tighten the axel nut about 1/4 to 1/2 a
turn. While doing this rotate the wheel.
An alternate procedure is to tighten the axel nut only until the wheel
`begins' to resist being rotated. Rotating the wheel at least a few
revolutions while the axel nut is "over tightened" will allow the tapered
rollers to align themselves within the races while under the artificially
induced load.
Once this is done release the load on the bearings (back the axel nut off)
then gently turn the axel nut with the tool of choice until the axel nut
mechanically stops. At this point turning the nut just a quarter flat or so
will apply some pre-load.
After the initial flight/s it will be necessary to recheck the fit and
re-adjust if or as required.
I have had the pleasure of adjusting quite a number of wheel bearings and
have not had any complaints about failures so far, However; I have seen
several opinions as to the finer points of adjusting axel bearings.
Their way:
I therefore suggest that you contact one of the bearing manufacturers or
Vans directly and take the above as a mere guide line as to procedure.

If the Dynon uses "solid state" gyros as part of their stabilization
mechanism then I can see the possibility that the problem could be RPM
related. Unlike the spinning mass gyro the solid state gyro rely on a
vibrating electric element to establish a spatial reference plane. IF
the
frequency of the engine (or a harmonic of the basic engine frequency)
happens to fall within the proper range then it could be influencing the
vibrating element and confusing the processing of the signal from the
that
element. If that is the case, then perhaps better physical isolation
might
cure the problem.
Any correlation between engine type such as the larger 360 causing
more of
a problem than say the 320??

I don't know exactly what it is but the sealer they use for tennis courts is
available in different colors. That is probably better as it is formulated
for it. Lacking that industrial grade epoxy floor paint will stick to
asphalt but as the aslpshalt "flakes" you will get paint colored asphalt

Among all the prior posts on this issue Paul, the following is my favorite: Tighten
until you just start to feel some drag then back off a tad til the drag
is gone. The grease prevents good sensing of end play & the tapered roller bearings
will have a short life if they can bang around even a little. Both end
play and rotational effort take some tactile sensitivity so whichever method
you choose, work at it til you can feel the differences. Don't worry about using
a wrench to tighten the nut.

I have seen absolutely no sensor errors (or heard any reports of them or
any other type error for that matter) with my EZ-Pilot autopilot.
Haven't heard any reports of sensor problems with the DigiTrak, either.

| Subject: | asphalt floor covering |
--> RV-List message posted by: <kbob@cox.net>
Jack,
I second the thin set concrete idea. Here's how I would do it. Sweep and spray
off the area first. Use a detergent and brush on the oil spots. You can get
most of it up.
Then get the bagged thin set tile material, or make a 50-50 blend of fine sand
and cement. Mix it a little on the 'wet' side for easy spreading. Get a broom
and floor squeegee and spread the mix. Work in small areas with small batches
until you feel good at applying it and the right consistency required. It
will take a bunch of mix depending on the voids in the asphalt. A second coat
may be required to smooth it out.
After this cures (keep it moist for one week), get some of the epoxy floor paint
at Home Depot. The industrial stuff is better (tougher, won't peel up under
hot tires, etc.) but is hazardous to apply (use a respirator). The other stuff
is more like latex, which will work fine in low traffic areas, but will wear
and need touch up. The instruction will say to make sure the floor is free
of moisture so it may take weeks to 'dry' depending on the climate.
I sealed my concrete garage floor joints with industrial elastomeric sealant, then
epoxied the floor with the industrial epoxy stuff. It took 4 gallons (2 of
the 2 gallon kits) to do the floor of a 3 car garage. It also took 2 coats
for full coverage. The garage is very bright, spills clean up well, parts don't
get lost, sweeping or mopping makes it look new, wear is nearly zero after
800 hours grinding the metal filings around.
Paint the walls white for even better lighting. All this work is a very worthwhile
investment in the property, ease of construction or maintenance, and pleasant
work space.

Unfortunately, We are sending back our Digitrak 200VS for the second time
now for sensor errors. Both times for the roll sensor.
The first time the autopilot would send the aircraft off on some unknown
direction. Trying to override it caused the shear pin in the roll servo to
shear. Trutrak fixed both the servo and controller quite promptly and we
had everything working prior to Arlington.
The second time was about two weeks ago on a long X-country flight. The
aircraft started wandering about 5 degrees left and right of the flight
path. As time went on it got worse. I contacted Jim at Trutrak and he
confirmed that the roll sensor has gone crazy again.
Trutrak has also sufferd a big blow this last week. One of their chief
engineers was killed in a car accident. According to them it is going to
slow things down for a few weeks until they can get the work load
re-organized.

The new software indeed seems to have fixed the problem on the Europa. This involved
a change in the sampling rate. Here's a copy of the note from my Europa
friend to Dynon:
Hi John and Nick,
I have just returned from my first test flight after loading version
1.09.04 to my D-10. I am pleased to report that I ran the plane straight
and level at 100 rpm intervals from 5800 engine rpm ( 2386 prop rpm for
take off) to 4000 rpm, ( 1646 prop rpm for low speed approach descent).
I did not see any instability at any speed. The attitude indicator
appeared to be indicating correctly during the whole flight. The turn
indicator also showed no oscillation or erratic indication. This is a
preliminary feedback, of course, but my problem of erratic horizon and
turn indication.appears to be cured.
With best regards,
John

Hi all,
Can someone straighten me out on a minor landing gear issue? The
manual says to tighten the axle nut until all "side play" is removed
but the wheel still turns smoothly. Frankly, I don't see any side
play even with the axle nut removed, and the wheel turns pretty
smoothly regardless of how hard I tighten by hand.
So... how tight is tight? My intuition is to tighten it just barely
snug, fingertip tight...?

An RV-4 pilot here had that kind of trouble with his TruTrak Digiflight 200.
He experienced the problem within a few weeks of installation. Excursions in
pitch, as I recall. He said that TruTrak suspected it was vibration related
and had him return the unit for new gyros and software. TruTrak told him
that this was not the first instance of this problem on RV-4's.
He has it back from TruTrak but hasn't flown it yet because of other work on
the aircraft.
This is all second hand info so it would be best to contact TruTrak directly
for the straight skinny.

| Subject: | TruTrak Roll Error was Solid State gyro Dynon D-10 errors |
--> RV-List message posted by: "Ross Mickey" <rmickey@ix.netcom.com>
I had similar symptoms but the problem was not roll sensor error but
repairman error. It all started on a bumpy flight to Scappoose in which
the shear pin broke on the aileron (roll) servo. This was one of the
early shear pins that were manufactured to break a bit to early. The
new ones are more beefy. TruTrak shipped me a couple of new shear pins
(post haste as they always do) and I installed it a few days before I
left for Oshkosh. During the entire flight, the autopilot would first
rock left then right then left then right.....you get the picture. I
was mystified because in the 60+ hours I used the TruTrak it had always
been rock solid. At Oshkosh, Jim Younkin came out to my plane and found
that the shear pin on the aileron servo was not tightened all the way
into the hole on the servo arm. To help you understand this more, the
shear pin is a brass screw with a large barrel head that has been
machined down a bit right below the head. The head of the screw has to
go all the way INTO the hole of the servo arm. Apparently, I had
installed the shear pin so that the head of the screw was on top of the
servo arm (like every other screw on the airplane). What was happening
was that the servo arm had about a 1/16" play on each side of the shear
pin. The rolling I was experiencing was just the servo taking up the
slack. I installed another shear pin at Oshkosh and on the return
flight the unit was rock solid again. Another thing to remember if you
replace the shear pin. Don't over tighten it. Snug it in with a bit of
blue lock tight. If you put to much torque on the shear pin it will
weaken it at the machined point and it will shear to soon...like during
moderate turbulence at 1500 feet over North Dakota...but that is another
story all together.
Now my TruTrak DFC 250 is rock solid again.

| Subject: | Dynon D-10 errors |
--> RV-List message posted by: "Jamie Painter" <jdpainter@jpainter.org>
All this talk of the Dynon solid state gyro problems has led me back to a
project I worked on a couple of years ago. We prototyped a forklift workload
automation system for a large (huge) sugar-water company. The general purpose
of the system was to assign work to the drivers and to warn them of safety
hazards such as the forklift getting off-balanced or warn them of another
forklift coming around the corner. Yes, it was collision avioidance for
forklifts...very fun stuff.
At any rate, we experienced a similar vibration issue with some of the gyros.
Our solution was not to simply change the sampling rate, but to randomize the
sampling rate and apply weighted averages to the readings. In other words,
instead of deciding we were going to sample the gyros every 100 milliseconds,
we decided that we would sample them every 100 milliseconds plus or minus 0-20
(determined psuedo-randomly) milliseconds. The gyros still displayed some
random data in the the form of vibrations (taken care of by the weighted
averages), etc. but the problem of momentary gyro 'drift' was taken care of.
This solution worked beautifully and was rock-solid.
I'm not familiar with the hardware in the D-10(a) but I wonder if they've
tried that approach yet (or if it's even possible with their sensors).
Another approach Dynon might try would be to somehow detect vibration
frequency (is there such an instrument?) and alter the sampling rate
accordingly in real-time.
Now, with respect to the D10(a) in airplanes, my first impression would be
that people with EI's should *probably* see the problem more than people with
dual mags, since the engines run smoother (read: more stable, less random
vibration frequencies)...but this is merely a (semi-)educated guess.

sure, accelerometers could be used to detect vibration but then that's more hardware
and more $ so not a good solution for Dynon and us.
SW solution is fine and if you can't see a drift that's adequate.

The new software indeed seems to have fixed the problem on the Europa.
This involved a change in the sampling rate. Here's a copy of the note
from my Europa friend to Dynon:
Hi John and Nick,
I have just returned from my first test flight after loading version
1.09.04 to my D-10. I am pleased to report that I ran the plane straight
and level at 100 rpm intervals from 5800 engine rpm ( 2386 prop rpm for
take off) to 4000 rpm, ( 1646 prop rpm for low speed approach descent).
I did not see any instability at any speed. The attitude indicator
appeared to be indicating correctly during the whole flight. The turn
indicator also showed no oscillation or erratic indication. This is a
preliminary feedback, of course, but my problem of erratic horizon and
turn indication.appears to be cured.
With best regards,
John

There have been reports of similar errors with the True Trak units,
although I have not seen any on 'the list'.
Early in the development of the Trio unit they experienced similar
errors with a particular type of gyro. They delayed deployment, at least
one year, until a new gyro, MEMS I believe became available to them.
According to them ( I have spoken with them this week to inquire
specifically on this mater), and my experience to date, they have not
received one single report of any gyro errors of this nature.
The Mems gyros are used in inertial reference systems on certified
aircraft.

If the Dynon uses "solid state" gyros as part of their stabilization
mechanism then I can see the possibility that the problem could be RPM
related. Unlike the spinning mass gyro the solid state gyro rely on a
vibrating electric element to establish a spatial reference plane. IF
the
frequency of the engine (or a harmonic of the basic engine frequency)
happens to fall within the proper range then it could be influencing the
vibrating element and confusing the processing of the signal from the
that
element. If that is the case, then perhaps better physical isolation
might
cure the problem.
Any correlation between engine type such as the larger 360 causing
more of
a problem than say the 320??

I am installing a Bob Archer VOR antenna in the fiberglass 7 wingtip. I
have individual strobe power units which I also intend to mount at the
wingtips. Has anyone had flight experience with such a setup and have there
been problems with interference (having the power supply so close to the
antenna)?
The instructions say to route the navlight power cable along the front of
the antenna, but I am somewhat reluctant to run the strobe along the same
route because of the high voltage. Any experience with this?
I plan on mounting the strobe power supply on the last rib with wires
running to the wingtip cutout in the typical location. I've been scratching
my head about this for a few days and feel stumped because there is no way
to test it until the bird takes wing. Any help -- any ideas -- are better
than where I am now .....

I'd be carefull of comparing the ongoing Dynon issues with any TruTrak
units....I just spent a good deal of time on the phone with Jim Younkin
today, and one of the subjects we discussed was this very issue.
Trutrak used a completely different set of hardware and software. Before
discussing anything that "looks" similar, one should call Jim directly.
He's happy to tell you about anything he's found, how his units work, and
any failures or in-accuracies they have found or know about.
His opinion is NOT to hide any known defects, but rather publicize them so
no-one gets in trouble and so he can get them fixed. He's one of the most
honest people you'll find, and has forgotten more about this stuff than many
of us know. Same goes for the people at Trio.
Anyway, I wouldn't hesitate to all TruTrak directly and ask.
Cheers,
Stein.
P.S., Mike...you should have bought a SteinAir Dynon harness and your
software load would be going smoothly :)

0.70 RCVD_BY_IP Received by mail server with no name
--> RV-List message posted by: "John Wiegenstein" <n727jw@hellerwiegenstein.com>
At the risk of drawing unwanted attention from the list police for posting
improper material (Herr Ashcroft and his boys will probably be putting me
into some database now.....), I am VERY pleased to report that RV-6 N727JW
has finally taken flight. I began work on this slow-build tipup 6 in early
1995. Family, law practice, and other hobbies meant that the project
stretched out longer than many, but I kept at it. N727JW finally received
its airworthiness certificate on 9/6/2004 from DAR James Devany (Joyce, WA),
and on 9/8/2004 at 0951 PDT I lifted off Rwy 17 at Tacoma Narrows Airport
(TIW) in Gig Harbor, WA. The 40 minute flight went smoothly, with no squawks
except a slightly heavy right wing, and the need for a small amount of right
rudder trim. Power is a new O-360-A1A with a new Hartzell "blended airfoil"
C/S prop, both from Van's, so takeoff and climb performance were impressive.
Panel is "not quite IFR", and empty weight without paint or wheel/gear leg
fairings ended up right at 1,000 lb. Mike Seager's transition course was
worth every penny, and helped to make the flight as "routine" as could be
expected. An absolutely fabulous feeling and experience!
I'll say it again, even though its been said many times before: to all you
guys (and gals) still building, keep pounding those rivets and pressing on,
whatever the hardships and temporary setbacks. It WILL be finished some
day, and when it is and you have taken flight, you will have joined a very
small, elite group, and will experience a level of personal satisfaction and
accomplishment that few people know. You will also have learned a
tremendous amount of information about your aircraft specifically, and
aircraft construction, certification, and design in general. To me, that
can only make you (and me) a safer, better educated pilot once the bird is
ready to leave the nest.
And, to those who have posted advice, comments, etc. on this list and in
other forums (fora?) over the years, thanks for the good information. The
'net and broadband have allowed us all to wallow in way more garbage than we
might like, but it also has nuggets of great information, and this list has
had many of those over the years for a lurker like me. I cannot imagine
how our forebears created homebuilts before the internet and before the kits
that we all enjoy today. My hat is off to them.
Gotta go fly now!

Kathleen,
I have Bob's VOR antenna in the wingtip of the -7 along with the
strobes--but not the power supplies. I would also give Bob Archer a call,
he was very helpful when I called him about my installation. Mine works
perfectly and I doubt that having the power supplies on the outboard rib
would have much effect at all.
Bob will want you to run your strobe wires along the leading edge of the
antenna along with the nav light wires. I believe this is the way he shows
it on his schematic.

Kathleen: I have exactly the set up you describe in my RV-6 wing tip. I
was also concerned so I called Bob Archer directly, which BTW I would urge you
to do as a confidence builder. Anyway, Bob assured me that I would not have a
problem so long as I grounded the shield of the high voltage cable to the
power pack as described in the instructions. Give Bob a call at 310-316-8796.

Have had the setup you describe and it works great for the past 7 years.
See Sam Buchanan's web site for what it did. Looks like a very similar set
up to me except I have the Wheelen power supplies in the wing tip instead of
the Aeroflash. http://home.hiwaay.net/~sbuc/journal/sportcraft.htm
I can drive over to Bob Arche's house and ask any question that you may
have.
The 2nd Nav antenna that I have is used for the FM signal to my

My compass has run low on fluid after 3.5 years of slooooooowly losing fluid somewhere.
No idea where the leak is, because I've never noticed a drip, a damp
spot, or anything other than a slowly falling fluid level. Anyway, what's involved
in re-filling it? How does it come apart? How does it go back together?
How tight should I torque the fasteners that hold it together? I'd appreciate
the whole run-down if someone can give it.
Based on advice from the list and other sources, I'm going to refill it with low
odor mineral spirits.
Thanks in advance,

For anyone interested here is a link to an Analog Devices iMems data sheet.
I have no way to know if this is the device used but the 3dB Bandwidth
of this part is 40Hz which corresponds to 2400 cycles per minute. At the
engine rpms some have said to be problematic there will be a significant
signal content, and down only 4-5dB.
As I said before this will need to be removed to prevent the alias
errors. Oversample->LowpassFIR filter->decimate->good data. Easy as long
as they have sufficient CPU clock cycles spare.

At the risk of drawing unwanted attention from the list police for posting
improper material (Herr Ashcroft and his boys will probably be putting me
into some database now.....), I am VERY pleased to report that RV-6 N727JW
has finally taken flight. I began work on this slow-build tipup 6 in early
1995. Family, law practice, and other hobbies meant that the project
stretched out longer than many, but I kept at it. N727JW finally received
its airworthiness certificate on 9/6/2004 from DAR James Devany (Joyce, WA),
and on 9/8/2004 at 0951 PDT I lifted off Rwy 17 at Tacoma Narrows Airport
(TIW) in Gig Harbor, WA. The 40 minute flight went smoothly, with no squawks
except a slightly heavy right wing, and the need for a small amount of right
rudder trim. Power is a new O-360-A1A with a new Hartzell "blended airfoil"
C/S prop, both from Van's, so takeoff and climb performance were impressive.
Panel is "not quite IFR", and empty weight without paint or wheel/gear leg
fairings ended up right at 1,000 lb. Mike Seager's transition course was
worth every penny, and helped to make the flight as "routine" as could be
expected. An absolutely fabulous feeling and experience!
I'll say it again, even though its been said many times before: to all you
guys (and gals) still building, keep pounding those rivets and pressing on,
whatever the hardships and temporary setbacks. It WILL be finished some
day, and when it is and you have taken flight, you will have joined a very
small, elite group, and will experience a level of personal satisfaction and
accomplishment that few people know. You will also have learned a
tremendous amount of information about your aircraft specifically, and
aircraft construction, certification, and design in general. To me, that
can only make you (and me) a safer, better educated pilot once the bird is
ready to leave the nest.
And, to those who have posted advice, comments, etc. on this list and in
other forums (fora?) over the years, thanks for the good information. The
'net and broadband have allowed us all to wallow in way more garbage than we
might like, but it also has nuggets of great information, and this list has
had many of those over the years for a lurker like me. I cannot imagine
how our forebears created homebuilts before the internet and before the kits
that we all enjoy today. My hat is off to them.
Gotta go fly now!

Aircraft Spruce sell a repair kit and refil kit that should help you
out. Try this link but it looks like it deals only with the Airpath
Compass. I'm sure you could find a kit for your model by contacting the
Mfg. The kit include the fluid and diaphram. I had mine fixed by my
local A&P before I new I coiuld do it myself.

No idea where the leak is, because I've never noticed a drip, a damp
spot, or anything other than a slowly falling fluid level. Anyway, what's involved
in re-filling it? How does it come apart? How does it go back together?
How tight should I torque the fasteners that hold it together? I'd appreciate
the whole run-down if someone can give it.

Same thing here, KB. My compass is flopping around with very little visible
means of liquid support. Never saw a drop of fluid anywhere. Must be
seeping out and evaporating. Took five years to do it. I ordered a
refill/repair kit from Spruce. Bummer is that I installed the thing in a
horrendous location without some form of captive nut or those grasshopper
nuts thingeys. (How DID they get them off the grasshopper and what did he
think about it?) Gonna be a bear to remove. Won't do THAT again on the
RV10 that's for sure!

Hi Ed
I'd be interested and I'm certain that Dynon would as well to know what
engines are in the planes that are experiencing these problems. As you & I
both know, even the smooth rotary has it's own harmonic vibrations, however
in almost 40 hours of flying my Dynon I've yet to see any errors (but I'm
watching closely). I'd like to hear what engine/prop/ignition combinations
are involved to see if there is a common thread.
When I first received my Dynon, I brought it to work at a large mill (had
to show it off to the other instrument mechanics:-) and when turned on it
immediately showed a ~30 degree right bank and a ~10 degree down pitch. The
error remained steady at all times within the shop at the mill. The shop is
solid concrete and feels rock steady, but there was something in there that
was affecting the Dynon. At home it performed flawlessly again, so I brought
it back to work the next day. Same error again. At that time I began to
wonder if vibration or quite possibly electromagnetic interference from all
the industrial equipment was the cause. After installing it I'd pretty much
forgotten about that until now.
Just another bit of info to consider.....
Todd Bartrim (Love my Dynon)
