Without a whole lot more fairly specific data I have to take exception to
the logic that because one unit grays out where another doesn't makes it
worse.
There are only a few of these sensor technolgies out there, and they are all
limited by similar factors. The fact that one manufacturer doesn't find the
data acceptable at a certain extreme and so installs an ergonomic response
to that data may mean that their product is far more safe then the units who
don't do this.
I am inclined to favor this feature because it tells me the manufacturer has
tested the specifications of the components sold to them, and won't deliver
those flaws without warning. That's an attitude I can trust to be looking
out for my well being.

Miguel,
this is the second time I have heard of this, in the last case the FP needed
to be replaced.
The unit was installed with an Ellison carb and the excessive pressure
caused it to run very rough. (I'm guessing rich, but I didn't get to see it
run)
The only thing we could think of was either the diaphrams stiffened up or
the spring that sits between the lever and the diaphram plate got guued up
enough to not be as springy.
In any event a new pump fixed the rough running. If you have an M/S carb the
rough running shouldn't happen, but I don't know what the rest of the
failure pattern is for the pump, as it was changed out right then.
The other note was that the change wasn't gradual. One flight it was OK and
the next flight it started up just south of Vans, and they landed in Salem.
Certainly would consider a different gauge for an instrument check. Also
passed this by a good ole boy in Schellville who made a living for many
years rebuilding things like fuel pumps and he had never heard of it.
If you keep flying that pump, make sure the boost is solid and can flow
bypass the engine pump.
W
PS, sorry for talking about an RV problem, I'll try to avoid that in the
future. :{O
Lets see,,, RVs spin better with a tailwheel, interior primer, tip up cigar
holder, but to recover you must nuke a fat gay whale for Jesus while singing
galic ballads in hebrew and while attempting the Heimlich manuver on your
knee that is opposite the direction of spin.
And they pay people to train you how to do this.

Subject: RV-List: High Fuel Pressure
--> RV-List message posted by: "Kosta Lewis" <mikel@dimensional.com>
I have for years been running between 3-5 to 6 pounds of fuel pressure
depending on I don't know what. Lately I have noticed it keeps at the
high end, 5.5 to 6 at cruise, with a slight increase (needle width) with
adding the boost pump. At idle, it inches towards 7 to 8, which is
redline. No change with fuel tank selection, no change in climb power,
take off performance, fuel consumption. No fuel flow meter, so don't
know that. Fuel line to the carburetor is clear; screens are clear;
nothing in the gascolator screen or sump. I would assume if there was a
blockage before or in the fuel pump(s) the pressure would be low.
Nothing blocking the lines from the pumps to the carb. No leaky fuel
lines. Only recent change: fuel selector valve (nylon innards) that now
is very smooth, as opposed to the old one (brass) that had to be lubed
every 10 or so hours. Hmmmmm. Ideas?

Not to second-guess you, but two EFIS Lites take up no more space (or not a
significantly greater amount of space) than a conventional AI and DG. I
Googled "RV4 panel" and came up with this image:
http://www.techass.com/csimpson/rv4/rv4_98.jpg
So there can be room on an RV4 panel for two EFIS Lites *and* conventional
pitot-static instruments. Of course, that doesn't mean your panel is laid
out like that....

As you say it's your airplane...and your hide...but going without any steam
gauges is not true redundancy. What you've got if you do that is two systems
that have the exact same failure mode. If you have an electrical fire behind
the panel you could very well wind up with an airplane that has no
instruments at all.
Conventional pitot/static instruments continue to work even with no power in
the airplane whatsoever.

I just want to clarify something from my earlier post. It implied that the
person from BMA doing the badmouthing was Greg Richter. It wasn't, it was
someone else. Not sure who.
Also, while BMA may have released less than production ready stuff. I don't
know of anyone who was actually "screwed" by them. I know several people
who suffered through the frustration of getting everything right, but as far
as I know everyone was eventually taken care of.
I used to work in the s/w business. There were a lot of brilliant people
who could create great stuff. Greg is one of those people. I'm guessing he
misjudged the amount of additional effort and expertise necessary to go from
a one-off in his Cozy to a fully reliable, fully supported, efficient to
build, production enviornment.
Just trying to be fair.

Ed,
I got the GPS 18 as a test unit from a friend that works at Garmin so I did not
have to worry about the warranty. But I split the case and removed the four
magnets so I could mount it just in front of the compass. I was surprised how
strong those little magnets were. You definitely don't want them near your compass.

On one hand, I agree with you, but I have seen a very limited electrical
fire in a 182 that melted through the pitot system lines. It wasn't
serious, but very interesting to note the difficulty it would have caused
IFR. One thing about building is that each person has to determine and
accept his or her own level of risk. That is unlike certified aircraft
where you are expected to assume that all the possibilities are accounted
for. I have simply determined what I think is the right level for me and my
type of flying. I don't think you can expect that a real "behind the panel"
fire wouldn't affect the all the instruments, but I fly anyway....

Don,
Your clarification more closely parallels my experience with Blue Mountain.
I would be willing to bet that the guy who did the badmouthing was their
one-time general manager. I bought before he came on board and was relieved
to see him leave. Besides the bad taste it leaves, I don't trust people who
badmouth their competition. I have never heard Greg Richter do that.
My experience with Blue Mountain has been mostly good. On the plus side, my
EFIS/one is a much more refined product now than it was when I bought it a
couple of years ago. They have continued to improve the software (which I
think was excellent to begin with), adding some features and improving
others. They now can sell a package of engine sensors, which wasn't the
case when I started with them.
On the other hand, I really liked their open and free-wheeling discussion
board, until I had one of my rare posts that was less than complimentary of
Greg's book Aircraft Wiring for Smart People removed from the discussion
board. My post was to point to the location of Bob Nuckoll's devastating
paragraph-by-paragraph review of Greg's book, so it is understandable if not
acceptable to me that my post was removed. Up until that point, I had great
confidence in Greg's integrity. And I have been waiting for almost a week
now to get a return authorization number from them to ship my CPU back for
repair. Somehow I screwed up a software update and they tell me it has to
go back to Tennessee to be restored, but they seem to be too busy getting
their latest generation of the EFIS/lite out the door to deal with me. To
be fair, I did tell them it's not a big deal because I am a long ways from
flying yet.

That's good to hear! :-) I called a couple of weeks ago
to see if the EFIS/Lite G3 is shipping, and they said if I
ordered then, it would go out in about 2-4 weeks. Does
anyone know if the new EFIS/Lite G3 is actually shipping?
I probably won't "need" it for another couple of months,
and I want to order as late as possible.
Thanks,
Mickey

Questions for those who have done their fuel lines.
When screwing in an elbow to a pipe thread connection
What do you do if the elbow does not face the right direction
when torqued? Back it of or torque it more?
Also does anyone put sealer compound on
the threads?

I know some won't like this idea because it adds one more fitting in the
mix, but over all I think it is much better solution and less likely to
leak in the long run. I use a straight NPT to 37 degree flair fitting
then use a 37 degree swivel elbow so I can face it anyway I need to.
This method lets you tighten the NPT fitting the correct amount with out
worrying about having to turn it in another 180 or 270 degrees to get it
where I want it. The 37 degree flair fitting with two tapers forced
together make a very tight seal, much better than a pipe thread in my
opinion. An advantage to this is you can remove or readjust the swivel
elbow as much as you need to, where a pipe fitting should be tightened
once and never moved, if it must be removed, it should be replaced. The
only disadvantage I have found to this system is it takes a little more
room, and sometimes clearance can be a problem. In my perfect world, we
would use SAE O-Ring boss fittings instead of pipe threads.

I always use thread lube on these fittings. " Parker Fuel Lube " is the
standard of the industry,but there are others. Just put it on the male half of
the joint,so you don't get it into the line - it plugs things up in there.
The fuel lube prevents seizing and lets you adjust the angle easier,plus it
seals against leaks.

--> RV-List message posted by: "JOHN STARN" <jhstarn@verizon.net>
Would need a bit more information BUT depending on how many degress of
turning is still required. IF you use fuel lube or other pipe dope it will
reduce friction and the fitting will nornally go in further without over
streeeing the fitting. It's never a good idea to "backoff" a fitting. There
are times that just removing the fitting and reinstalling it will allow up
to a 90 degree tighter fit. The use of "pipe dope/fuel lube" on the MALE
THREADS ONLY should work up to 270 degrees. Lube it, install, tighten,
backoff and retighen until it points where you "must" go.
I didn't spend the night at a Holiday Inn but I did spend 20+ years as a
Plumbing & A/C contractor.

Questions for those who have done their fuel lines.
When screwing in an elbow to a pipe thread connection
What do you do if the elbow does not face the right direction
when torqued? Back it of or torque it more?
Also does anyone put sealer compound on
the threads?
I use a pipe thread compound (Rectorseal #5) for the fuel lines, brake lines,
and oil lines. Been using this product for years in the HVAC business & I trust
it! Put on pipe threads only, and don't use for metal to metal flare fittings.
FWIW, my brake lines have not leaked in 3 years with this product.
As to backing off a thread, I'd only back off slightly. As to additional torque,
it's a question of how tight you figure it already is. You can always back
the elbow out, put some new pipe compound on & try again. Results will vary.

| Subject: | gas struts pull canopy frame fwd |
--> RV-List message posted by: "Wayne Pedersen" <wayne@pedersentransport.com>
I just finished installing the gas struts on my -7a tip up canopy. Worked
great until I noticed that the pressure from the struts in the closed
position pulled the canopy frame 3/16's of an inch forward ! This movement
ruins all the trimming filling etc and there must be an easy solution.
I have yet to install the canopy. I plan on installing the canopy without
the struts hooked up and when the canopy is in it permanent position will
it hold the frame in the proper place ?
Thanks for the help

Wayne:
Have you installed the canopy stiffener kit yet? I recommend it. It
works pretty good.
Failing that I do know one builder who installed some nylon blocks just
forward of the canopy frame on each side to take the force when the
canopy is closed. Mine hasn't been on enough to tell, but I don't think
I need the nylon blocks.

| Subject: | Air Flow Performance bracket interference |
--> RV-List message posted by: "thomas a. sargent" <sarg314@comcast.net>
I just positioned my IO-360--B2B (still on the engine hoist) up against
the engine mount on my 6A. So, it's close to, but not at, its final,
mounted position. It looks like there is going to be some interference
with the 6A engine mount tubes and the AFP throttle and mixture cable
mounting brackets. In fact I vaguely recall the guys at AFP mentioning
to me a few years ago that there would be a minor problem here.
I realize I have to wait until the engine is mounted to make any
adjustments, but what is necesary? Do I just grind away the interfering
portions of the brackets? Does any one have any pictures of what they
did with their 6A + IO360 + AFP configuration?
Thanks

Tom,
I recall the same thing. I cut away as necessary, and I also fashioned a
strut to stiffen the AFP bracket. Seems like this strut went up to a sump
mount bolt.

I noticed the same thing. What I did was to put a 1/4 inch bolt in the
tooling holes bulkhead forward of the panel, with the heads facing aft.
Put nuts on the bolt on either side of the bulkhead, so you can adjust
how far aft the head is. When the canopy closes it will contact the
bolt heads and prevent it from being pulled forward. It does take some
trial and error to get the bolts adjusted right. I wish I had a picture
to make this more clear, next time I'm at the airport I can take one if
this doesn't make any sense.

Excellent idea! I absolutely DETEST pipe threads!
Your idea is a great way to get the correct torque on
the pipe fitting, & use a real fitting to give you the
proper elbow orientation!!!
