Ninety bucks more for less? I don't think so. I guessing we'll soon see the Aviation

| Subject: | Attaching QB Fuse to Tailcone |
Getting ready to attach the QB fuselage to my tail cone.
Section 29-2 describes drilling #30 pilot holes for the longeron
attachment using the template provided.
The only issue is that the QB doesn't come with this template, so I have
no clue where to drill these attachment holes.
I know someone else has ran into this issue before me.
Anyone get word from Vans on their proper location?
Thanks,
Phil

I just measured mine, which were drilled using the template. The most
aft
hole is centered about 7/16=94 from the aft end of the longeron. Each
of the
other holes appear to be on =BE=94 centers going forward.
I don=92t think the precise location is critical as long as appropriate
spacing is provided. Btw, you=92ll be taking these bolts on and off
multiple
times later on during the build, so don=92t torque seal them quite yet.

I would affirm Bob's observation. The position need not be exact. Just make sure
that you are centered on the longerons so that you can get the nut on the bolt
(and the bolt tightened). Use the proper spacing to maintain the structural
integrity of the union. Note the position of the rivets that go in on a perpendicular
angle. You have to remove the bolts and nuts to get those rivets in
later, or go with a pop rivet which is ugly.

I like it. I flew in another RV10 that does not have it. It is not really a big
deal to just set the flaps manually. Still, I like the simplicity of the system.
It is easy to install - uncomplicated to operate and relatively foolproof.
I also installed a little Ray Allen sensor (the 1.2" model) that shows the flaps
position on my AFS3500 EFIS. My only note is that the change on the indicated
position on the EFIS from reflex to 0 degrees is too small to show an indication
on the EFIS.

Thanks for the help Bob and Mike!
Can you tell how they determined the center line of the angle?
Does it look like they determined the center line by finding center on
the interior side of the angle or the exterior side?
The angle is 3/4" x 3/4" and 1/8" thick.
If they measured on the exterior and then drilled, the hole moves closer
to the bend by 1/8".
Thanks again......

Tim,
-Thats not exactly right. when you have fuel or liquid mix with vapor or
air,pass by a volume of air you will see a change in pressure due to the co
mpression of the air. That's why you see fluxuation in pressure gauges.
-If you worked in the oil and gas business you see this all the time in p
ipelines. If you look at a trouble shooting manual for this, one of the rea
sons you see fluxuation in gauges due to vapor in the line and one of the f
irst thing it tells you is to get the air out.
-So what I was getting at is the gas(vapor) is getting into the line goin
g to the gauge so as other vapor mixed with fuel passes by your gauge line
it changes press due to compression of the vapor.

Pressure is pressure, it's just the compressibility that is
different.- If the vapor were at 50psi, it would push
down on the fuel at 50psi, and up on the fuel pressure
sender at 50psi, and the fuel would transfer that pressure
to the engine at 50psi.- Doesn't matter if it's vapor, or
what is in the line...it's just a diaphragm that is
displaying pressure.- Think of a manometer..it's using
air and liquid to show air pressure, but inside the
manometer is both air and liquid.- It's all the same when
it's pushing out against something else.- If you have a
pot of steaming water and you plug it, the steam will
build up pressure, and if you puncture the bottom of
the pot, the water will come out at whatever pressure
the steam is at.
So no, it shouldn't have an effect on the pressure reading.

Since you haven't gotten a reply I'll add my $0.02 worth. First the fact that
no one paints the firewall should tell you something. But if you have to do it
I would use hi temp paint. I don't know how hot it gets but the exhaust from
the oil cooler is at least that hot at times and I think the firewall gets hotter
as it sits following engine shutdown. The heater box may cook too. Pick
a color that goes well with oil and dirt since that is what will accumulate
there.

There are only two ways to get vapor. Either the line is hot enough to
vaporize fuel...only going to happen at low power, or if you have a
leak and are sucking air into the line. If the line is sealed, at high
power you will not have any fluctuations because the flow is
sufficient to keep the lines cool. The line from the spider to the
fuel pressure sending unit is sealed, and it will make little
difference whether it contains air or fuel, other than speed of
response.

I recall having a minor problem with my QB. If all the holes on the skins don't
line up perfectly check the longerons for interference. They may be too long.
Trim a little off if needed.

Sure, but when the air is compressing and expanding, the pressure of
the liquid is changing too....it's not staying steady. So if the gas
expands and causes a pressure rise, the fuel pressure will go up too.
The vapor may cause the gauge to move up and down but the fuel
pressure is changing then too.

| Subject: | Re: FireWall Engine Side Paint? |
Another person mentioned that the firewall could become in excess of 200 degree
during shutdown/cooling off period. He also mentioned that using a foil/heat
blanket barrier from Spruce Aircraft Supply on the engine side of the firewall.
So what I think I'll do is remove the existing low temp paint, repaint with
high temp paint and use a barrier material on BOTH sides of the firewall to
keep the sound and temps low and the avionics cooler.

Schumacher chargers are automatic, have an AGM setting and de-sulfating. Their
12248 is also sold at Wal-Mart as model SC-1200A. I bought one today for $45.
Less than half what I saw advertized on several web sites.
If you're using PC680's or other Odyssey models, this looks like the best option
to keep them in great shape.
