Les,
I believe most respondents interpreted your question correctly, and
were answering what to use on the NPT threads, not the flare fittings.
PTFE tape is to be avoided, because it leaves threads of PTFE on the
fitting when removed, and can migrate into the system when
reassembled. Fuel lube serves as a sealant that is not soluble in
typical hydrocarbon fluids. Pipe seal paste can be used, but residue
left on dis-assembly is still a concern.

For the panel builders, I found EZ Lube to be just the right stuff to
dab on the end of a screwdriver to hold those pesky screws in place.
Very handy.

For those that are using the Matco Parking Brake valve.=C2- If you are us
ing the old style rectangular valve, they have been known to develop an int

on.=C2- It is very slight, but was a source of trouble that took some tim

run-up at a busy airport and was able to get help from one of the FBO's.

Subject: RV10-List: Re: Fuel Lube on Brake Line Fittings?
I used fuel lube on my brake line fittings and had good luck with all excep
t two fittings at my Matco (after market) parking brake. I had one heck of
a leak (very messy brake fluid) on the floor of the pilot footwell. It was
a real mess. I finally used Permatex non-hardening sealant on these fitting
s and finally got the leak sealed. If you do not have a parking brake just
use the fuel lube. If you have the Matco parking brake valve (I love it) us
e Permatex on those fittings. I think that it is Permatex #2 but not sure -
it is a non-soluble sealant.
See my prior post (over 1 year ago) on the Matco brake.

Les, I'm still confused here. You said you were not referring to
compression fittings, but your Wiki example was .... compression fittings.
So,let's start by dividing the fittings. Compression fittings are used
on tubing without a flare. I've never seen blue anodized compression
fittings ..... but that doesn't mean they don't exist. Compression
fittings are typically brass, and found in the aviation isle of Ace and
others. They need no pipe dope or teflon tape on the compression side
or the NPT (National Pipe Thread)side, but some lubrication with fuel
lube or brake fluid can't hurt. The rest of the fittings we, in
aviation, use are 'AN' fittings, and come in steel, and in blue or red
anodized aluminum. The flare fitting gets it's seal from mashing the
flared tubing between the fitting and a sleeve, pressure applied by a
"B" nut. This isn't your standard hardware store 45 degree flare. It's
a 37 degree JIC flare, and is standard in hydraulic applications. This
joint doesn't NEED anything else, but some lubrication doesn't hurt.
Now onto the fitting side. Since we've covered flare fittings .... and
some AN fittings have flares on both sides, we're going to focus on
those fittings that screw into something hard, like an aluminum block.
These fittings use NPT (National Pipe Thread) which is a tapered thread.
This NPT fitting doesn't usually need anything to seal it. Sealing is
done in the taper. Leaks are caused by poor threading .... either the
fitting, or the part it's screwed into.
After all that, what about Teflon tape, or Teflon pipe dope? Why use
it? You have a leak??? Well, the fitting isn't tight enough ....
either in the taper thread side, or the "B" nut side, or there's a
manufacturing problem. But, you still want to put something in there. I
don't know why, but you do. Teflon tape isn't recommended since it can
migrate into the tubing because when you've changed the fitting, and
some string of Teflon tape got pushed into the hole .... and plugs
something up down the line. Pipe dope isn't recommended for the same
reason .... but the pieces aren't big, and stand less chance of plugging
something up. Fuel lube or brake fluid on the threads for lubrication
is OK, but by design the fittings are made to go together dry.
Sorry for the long post, but I want to see us be safe and fly for many
years without damage to people or aircraft.

Hi Linn
Apologies for the confusion. My original post was referring to the NPT
connections at the Matco brake. My follow up was because there were a couple
of posts recommending fuel lube on all the brake line fittings - this would
encompass the blue anodized flared compression fitting. It is my
understanding that flared fittings are a type of compression fitting
although not all compression fittings are flared. I stand to be corrected
though.

Now, I think I understand. Compression fittings usually have a .....
barrel, thimble .... whatever your favorite is .... that deforms to seal
on the tube, and also forms itself to the fitting and the nut. Flare
fittings aren't in the compression fitting category. They seal by the
mating flare and the surface area of the flare. They will, in some
cases, seal just fine with very little pressure. Most all flare
fittings I come across are way overtightened, and actually cause the
flare material to flow outwards, which causes premature cracking of the
now-thinner material. Do not ask the gorilla to tighten the B-nuts.

Hello fellow listers!
I am building an RV-10 and have been lurking here for a while. I have come
to a point in the build where I have to make a decision soon and I'm looking
for some input from those who have gone before me.
I'm building my wings and I am considering not including the stock stall
warning system. I am planning on installing a Dynon EFIS system with the
dual-holed pitot probe to provide AOA indication. I'm thinking that should
provide all the stall warning information that I would need. Am I
overlooking something? Is there a good reason to go ahead and include the
stock stall warning system?

Being one that worries about stalling, I installed mine along with an AOA
and the GRT stuff. You can never have to much stall warning in my book.
It is not a lot of work and I am sure it does not make my airplane go
slower...
I would recommend doing it..
What I did decide against doing was putting in two...one is each wing.. J

Hi Stuewe=2C
One thing to think about is if your piltot tube gets plugged. Not only woul
d you loss indicated airspeed but also your stall warning with the exceptio
n of airframe buffeting and control feel. Just something to think about.

Stuewe,
I have a similar set up. I chose to remove the
mechanical stall warning system on my -10 in favor of my Back Up Dynon
internal AOA and stall warning system. I have gouged myself more than
once on the mechanical warning tabs. It seemed like the perfect solution
to me (too). I also have the Dynon dual hole heated Pitot tube. Please
keep in mind I have had several other RV's w/o any audible stall warning
onboard. When trying to program the Dynon we have been unsuccessful at
properly setting up the warning system having followed the set up
procedure three different times. Please know that the set up procedure
is a series of intense stalls in different flight configurations. Trying
to do more than two series of attempts at setting up the system is
plenty enough stalls for one afternoon. Especially the power on stalls
that have you looking straight up will all the power available on our
ships. An assistant is a must for this set up.
The best I have got the system is to warn on stall
(pretty darn well) plus display the AOA. Unfortunately on the ground it
also displays full stall and warns even though I am on the ground
holding short. The system is speed sensitive and should not warn while
slower than some reasonable number (I forgot the number). To solve this
I have turned off the audio component making the unit useless at this
time for me. Please keep in mind I have not called Dynon to discuss
this as I was going to try one more time to refresh my memory on the set
up procedure before asking for help. Also know that I can be digitally
challenged having complained about updating the G900X due to it's DOS
like update procedures and pathetically non-specific (or accurate)
instructions. I have since updated the Garmin and have been pleased with
the results. I will get to the Dynon AOA over the winter.
Seems if one were interested in a simple and proven
solution keeping the mechanical stall warning would be a good choice.
Good luck,
Robin

I am building an RV-10 and have been lurking here for a while. I have
come to a point in the build where I have to make a decision soon and
I'm looking for some input from those who have gone before me.
I'm building my wings and I am considering not including the stock stall
warning system. I am planning on installing a Dynon EFIS system with
the dual-holed pitot probe to provide AOA indication. I'm thinking that
should provide all the stall warning information that I would need. Am
I overlooking something? Is there a good reason to go ahead and include
the stock stall warning system?
Thanks,
Stuewe

I have AFS and use their AOA and elected not to have a stall horn. I've struggled
getting the thing calibrated correctly even having done it 3 or 4 times. It's
still not correct. However, the -10 really is very docile and gives huge
warning about stalling so I really don't think it makes much difference what
you do, maybe unless your hanging it on the edge going into the jungle with a
very short runway and like the sound of the stall horn or the AOA and hope their
correct!!!! larry

I thought the same, but I bought someone else's kit and it's already
included ..... so I'll put it in.

I would agree, as long as the AOA is set up correctly.

Welllll ..... I really don't think you NEED either. If you stall
inadvertently .... then you aren't paying attention, and you're a
passenger. You should have plenty of warning .... turbulence on the
wings from air that is almost separating (a stall strip will help
here).... and the sound of the airplane ...... there are a lot of clues,
notwithstanding the airspeed and attitude indicator. The stall switch
is relatively cheap compared with your Dynon's AOA capability. I'll
have both .... the AOA probe which I'll make myself, and the stall
switch will be part of my MGL Odyssey installation.

I would personally recommend including the mechanical stall warning.- Hav
ing flown 4-fighters over the-20 years I have a deep appreciation for A
OA and lived by it.- However,-while I realize a lot of people get prett
y excited about-having an AOA indication-in the RV-10 I think it's unne
cessary in this airplane as the stall speed does not vary that much with th
e range of weight we carry and there's not a lot of aggressive maneuvering
going on.- More importantly, the mechanical system is simple and works de
ad on every time, I'm very impressed with it's accuracy and reliability.-
If you want the AOA system, go for it, but in my opinion there is no benef
it to not having the mechanical system tied in to the supplied buzzer.

Keep Van's stall warning system. Because when the buzzer go's off it will wake
you up. And it does not need a heated pitot tube and a glass screen to operate.

I was pretty sure I was going to go with steam gage airspeed, altimeter, plus a
TruTrak ADI for EFIS backup. But now that Dynon has their D-6 for $1600, I wonder
if that's a better route. I'd like to hear comments from users of either
system.

I installed neither the standard stall warning or an AOA system. The
Cheltons start warning below 70 KIAS and 60 KIAS. By far the most noticeable
is the elevator caused stick buffet. If you miss the physical
characteristics of the stall onset, you are comatose. Your AOA plans are
well sufficient.

Give some thought to the fact that Trutrack is not a standard EFIS.
It does not display pitch in degrees above/below horizon....and the
Dyon is. So your brain would have to switch between what the display
meant on one vs the other. I'd look long and hard at the Dyon Skyview
for primary and a D-6 for backup if you can't afford a second Skyview
screen.

I am surprised to hear that you are having calibration problems. Mine
has performed flawlessly right out of the box. I thought that the
unit comes from AFS set up for particular models of airplane? I seem
to remember Stein telling me something like that a couple of years
ago when I was building.

I think the main consideration of any backup flight instruments is
independence. All these electronic boxes have a dependency which has to be
there or it does not function normally or at all. For instance the GRT is
independent of GPS but the magnetometer is required. Some EFIS systems
require GPS for the PFD/MFD to give normal readings. The main concern should
be having two systems with different dependencies so that any single failure
of P/S air, GPS, or magnetometer does not jeopardize the safety of the
aircraft. Then the only common dependency is electrical power. That can be
handled by multiple batteries and power generators.
Dual Cheltons XBOW AHRS primary
GRT Sport GRT AHRS backup
Trutrak DF II VSGV second backup
Autopilot system selection switch
Single alternator, 3 (680)s primary and essential buses.

Just thought about this....
How often do the batteries in the Dynon's need to be replaced and are
they something you could buy locally or would you have to go back to the
Dynon for them?

I used to have one eyebrowjoined in the
middle by a deep furrow shaped like a stall warning vane.
Certainly got me to lower the nose, and I shook like s@#$
I went with a dual eyebrow system
