I would have to agree. I've got a Cherokee with a stock gascolator. I've
never found any water in the gascolator, ever, although I did find a piece of a
bugs(wasp) body lodged in the drain valve causing it to drain slowly. The
only water I've ever found was in the wing tank sumps, and only after washing the
airplane without taping off the fuel vents.(and then, not very much water,
maybe a half thimble full)

I've been watching this thread a little since it's one that pops up at least once
per year. In defense of those who are anti-gascolator types, I'm also one
who doesn't see the need for one. I had one in my old C172 and didn't like it
because it was prone to leaks. My AA-5A Cheetah did not have one. I flew that
airplane for over nine years and didn't crash and burn due to the lack of one.
In fact, I rarely saw water in the bottom of the fuel pump. It had one of
the round Facet types that had a place for settling and a small screen. I really
liked the little screen for catching anything big enough to cause harm.
When I built my -6A, I decided the gascolator was one thing I could do without
to make my fuel system even more simple and more like that on the Cheetah. In
fact, I even used the same kind of fuel pump that the Cheetah had. I've not
regretted my decision. I see very little water in the tank checks and have yet
to see it in the pump at inspections.
I still can't convince two of my friends that the gascolator is not needed. The
project I've just helped to complete has one. I guess it will give him a warm
fuzzy to have it. I'd be constantly worried about when it's going to leak.
Different strokes for different folks, I guess.

Hi, I'm just starting my RV7. I'd like to find a good rebuildable engine
core. I'd prefer an O360 but would consider a 320. I have a really nice
1978 Triumph Bonneville motorcycle. It's valued at $4700 and I'd like to
swap. Runs great, numbers all match (engine/transmission never been
apart), less then 7000 original miles, original except for new paint, seat
cover, cables, gaskets etc. A really fun British classics. Please call
Tony 802-878-7377 if interested. Thanks.

Guy, I don't know how your ailerons attach but the RV series uses a bearing
brackets mounted to the aft spar, one on each side of the aileron. The
aileron is simply removed by removing two bolts plus the rod end bearing
tipped push rod. Pretty much a non event.

Here is my opinion for what it's worth. I would personally have the carb
rebuilt and stay with it. Here's my reasoning.
carb Pro's
1. simplicity
2. less prone to vapor lock
3. easier starting.
4. easier to maintain
5. price for overhaul compared to injection is cheaper
carb cons
1. carb ice
2. must use the scoop on the cowl
3. gums up
4. more labor intensive than injection
injection pros
1. streamlined installation
2. better fuel management to cylinders
3. shouldnt have to worry about carb ice
4. doesnt gum up like the carb
injection cons
1. cost more
2. vapor lock
3. hard starts
4. more plumbing
5. high fuel pressure inside the cabin
6. complicated system
I am sure there are a lot more pro's and cons that I have not listed here.
Injection in my opinion can be a good thing, however I would think about
your application before installing the injection system on your plane. My
mind set is from the old school way of thinking that if a system aint broke
don't fix it. The carb has been around for years and years and the
injection system although proven is relatively still kinda new in the grand
scheme of things. Bottom line is, it's your airplane and in the
experimental category do what you want to with it. Hence the name
experimental. Hope this helps you somewhat.
Regards
Glenn Williams

I considered that possibility several years ago, Kevin, and addressed it by
putting a huge chunk of spray-in-place foam insulation over the back side of
the NACA scopop and the probe body... probably somewhere around R-10-worth of
GreatStuff insulation. I think part of the error is ram, part is hot air
leakage. Perhaps the duct tape test will tell, when I fly with the seams taped
shut...

I cut them out with a fine blade on my band saw, then rounded the
corners and brought them to final shape with a 1 inch bench belt sander.
After that, I smoothed the edges with a Scotchbrite wheel. Seemed to work
quite well.

In this case, measure three times, then cut. Actually lay out the
stiffeners in the position each one will go before you trim the "odd ball"
ones to size.
The elevators are not identical. One has the trim mechanism, the
other does not. This makes the stiffener layout different on each side.

Here's what worked well for me. I didn't have much luck using the tin
snips, I kept getting wrinkles along the cut that were hard to get out. I
wanted something that would make the cut in one shot and discovered the
hedge clippers hanging about six feet from my work bench.
http://home.teleport.com/~dianas-rv9a/ConLogR/ConLogR20030703.html
Scroll down a few pictures and you'll get to the part about the hedge
clippers. If you don't have any they are probably less than ten bucks at
your local Home Depot or equivalent. Read all the way through the trimming
part as there is a right and wrong way to do it and now I have some extra
scrap for my experimentation efforts. Drop me a line if you have any
questions.

This guy makes a plate you can buy that is the same width as your radio
stack and has the 196 cutout already cut... You would then just mount the
196 to this plate and mount it to your panel... I just got one from him for

Since it's apparent that the NACA duct is not a good place to locate OAT
probes, what kind of success has anyone had with other locations? Several people
have mentioned the wing root, but it seems to me that if there is enough
airflow to give reasonable response time that hot air leaking from the cowl will
still be a factor, true or am I missing something (again)? Anyone out there got
any real data on that location?

Why not put the OAT Probe behind the Pitot underneath the left wing?
It's (mostly) a shady location, and away from any engine generated heat leakage.
And there is a little disturbed air anyway where the pitot enters the wing, so
why not put one more protrusion (OAT-Probe) right behind it?

Since it's apparent that the NACA duct is not a good place to locate OAT
probes, what kind of success has anyone had with other locations? Several people
have mentioned the wing root, but it seems to me that if there is enough
airflow to give reasonable response time that hot air leaking from the cowl will
still be a factor, true or am I missing something (again)? Anyone out there
got
any real data on that location?

Hi Scott,
First let me say I'm not flying quite yet, so my advice is not from first-hand
in-flight experience with the specific hardware in question here, but instead
based on a lot of research into the options, the experience of others, and my
perspective as an avionics systems engineer:
1) For the wing leveler, I bought the Trutrak Digitrak unit. It's only a little
more expensive than the Navaid, weighs about the same for the whole system,
and has two big advantages over the Navaid: the control head is solid state,
and the servo has no clutch. Bottom line is (all other things being equal) the
Digitrak will last a lot longer (not as many moving parts to wear out) and operate
with greater precision. I know some of the guys using Navaids are happy
as a clam with these units and this is not meant as an insult to them, I'm glad
they're happy with it. But I know others have had some trouble getting them
set up to work well, and I have a friend with one in his Long-EZ who wants
to replace it with a Digitrak. The reason we put digital solid-state autopilots
in bizjets, fighters and airliners isn't just because it sounds sexy and high-tech
and costs a lot of money, it's because there are decided advantages that
have made spinning gyros obsolete. The Navaid used to offer a good value in
that it offered acceptable performance and was the only thing available in it's
price range that would keep you right side up and more or less on course.
Now you can get superior technology at a very competitive price...the Digitrak.
2) I have an EIS-4000 because of the outstanding reputation from its many users,
and my firsthand experience with Greg Toman at Grand Rapids who has been a
pleasure to work with and has incorporated some custom features in my unit at
no extra cost. I think this unit is the best thing going in the "bang-for-the-buck"
category of digital engine monitors. It's capable, easy to set up and
use, light, inexpensive, reliable, and takes up minimal panel space. The only
disadvantage is that it doesn't have gauge displays like the bigger, pricier
monitors....they are easier for the eye to read and spot trends at a glance than
digital characters alone, but the importance of this is not as great when you
incorporate the limit alarms that the EIS features. The fancier displays are
nice but not necessary.
Fuel probes: the EIS-4000 will work with almost any fuel probe out there, ask
Greg Toman if you want to be sure before buying. I installed Van's float sensors
but then Greg started offering some nice Princeton capacitive probes that
are custom bent and fit for RV tanks, so I bought them to retrofit before I put
the wings on for final assembly. Whatever you do I'd go capacitive...it's not
much more expensive and it should mean you'll never have to service it (as
opposed to the floats, where more than one RV'er has had to pull them out and
change them...not a fun job).
Bottom line is if you want to spend more time flying and less time fixing things,
and save weight and increase reliability, go solid state and eliminate mechanical
moving parts wherever possible. This applies to autopilots, fuel probes,
vacuum pumps (horrors!), gyros of any kind (I've got a Dynon, and no spinning
masses of any sort in my panel), engine instruments, etc. The only exception
to this rule that I can think of is for a prop...the rule still applies in
that a fixed-pitch prop (no moving parts) is more reliable than a constant-speed,
but unlike the other things I've listed, the constant-speed prop has a decided
performance *advantage* in it's favor. I've got fixed-pitch now, but C.S.
is in the long-term plans...
Just my humble $.02, no offense to any vacuum-sucking, steam-gauge-loving, clutch-clinging,
spinning-mass aficionados out there : )

I just got the great news that my wing kit shipped today, and I am need to make
some "wing" decisions. I would appreciate any feedback on the following:
1) Wing-leveler (Navaid vs. Trutrak) - Based on bang for the buck (one of my most
dominant considerations), everything I have read in the archives sounds like
the Navaid is a better choice. I do plan to fly IFR, so I will definitely get
one or the other. I would appreciate hearing from anyone that strongly supports
the Trutrak as a better option.
2) Guages (fuel monitoring) - Based on the reputation of some of the Vans-labeled
guages (and installation benefits), I think I will be going with the Grand
Rapids EIS-4000 for engine monitoring. I would appreciate hearing any "dislikes"
people might have with the Grand Rapids (haven't heard many). Also what type
of fuel senders they require (Van's resistive, Van's capacitance, other).
FYI...the fancy ones (Vision, ACS, etc.) are out of my price range.
Thanks,

Hey Kevin, that's some really interesting stuff...I had NO idea that ram rise could
amount to several degrees in an RV, I would have guessed it would be too
small to measure! I'll add that to my list of things to impress spam can pilots..."yeah,
she flies so fast I have to subtract several degrees from the OAT
reading because the probe heats up so much..!" Try THAT in your Cessna 150!
He he...
So...where would you recommend putting the OAT probe on an -8 or -8A? I was planning
to put it in the NACA vent in the lower right wing (or duct connected to
it). My thinking was that way it would be shaded, but not enclosed within the
structure such that it would heat up excessively when sitting on the ramp in
the sun. And it would not be affected in flight by heat from the exhaust or
engine. Seems to me that putting it in the wing root fairing for example would
probly work great in flight, but when sitting on the ramp wondering what your
density altitude performance is going to be for that hot/high takeoff, the probe
may be reading much higher than the real air temp due to the air space within
the fairing heating up. Whereas if exposed to the open air in the lower
NACA vent it should be more accurate, at least on the ground??
Where are you putting it on your airplane?

Just pondering - Bill figures the high OAT indications are telling
him that the air coming into the NACA scoop is warmer than ambient.
Perhaps it is, but I'm not sure why that would be (other than the ram
temperature rise, which I'll discuss later). I wonder if what it
really means is that the temp probe indications are affected by the
temperature on the back side of the probe - i.e. the cockpit. The
air in the cockpit is often quite a bit warmer than ambient due to
the green house effect, so perhaps this is what we are seeing. Or
maybe not.
Note: there is a bit of ram rise at play here too. The maximum
amount of ram rise in deg C is equal to TAS
2/7592, where the TAS is
in kt. So, if we are at 170 kt TAS, the max amount of ram rise would
be 3.8 deg C. Our temperature probes don't recover the full amount
of the ram rise though - the probe recovery factor is probably
somewhere between 0.7 and 1, so the actual amount of ram rise at this
condition is likely between 2.6 and 3.8 deg C.
So, depending on whether Bill has accounted for the ram rise or not,
the amount of error might not be quite as much as he reported.
However, it is still an error, and it makes sense to not put OAT
probes in NACA scoops.

Hey Guys, I just started looking at the installation for my RV-8A cowl. I
don't see anything that supports it at the front end near the prop hub.
Does it just rest on the baffle seal fabric? The plans show the front of
the cowl being located 1/8" higher than the prop hub, what holds it up
there?

OAT probes reading high in the NACA vents???
In my experience, when you're OAT probe is any where close to that 400 pound oven
on the front of your plane, the readings will be high.
Take a thermometer and stick it anywhere near the firewall. What do you get?
HOT!
If you want an accurate reading for OAT, you'll need to install it far out on the
bottom of your wing, insulated from stagnant air inside the wing, yet not really
in the slipstream where all of that friction will warm it.
Is it worth the trouble.... nah!

That sounds like a great idea. If you must spend more money for an
effective tool, try a band saw with a fine-tooth blade. It worked fine
for me, but I already owned the saw. If you know someone who owns one,
ask to use it for an hour or so. Cutting them to length can be done
with regular tin snips. I used the non-aviation type, cutting just a tad
long from each edge toward the bend. It probably took a little longer on
the scotchbrite wheel, but no deformed angles.

If you want to really impress them, put in a Mach meter :) And quote
your speeds in km/hr - "Oh yeah, this thing really goes - it cruises
at 320".
I came to the same conclusion you did about where to put the OAT
probe - mine will go in the under wing NACA scoop. I still expect
there may be some error when sitting on the ground on a sunny day, as
the ramp typically warms up above ambient temperatures due to the sun
hitting it, and it probably warms up the air close to the ground. I
really don't expect hot/high T/O performance is going to be a
problem, unless I deliberately go into some stupidly short strip, or
some place with crazy obstacles. Of course the hot/high performance
will be greatly decreased compared to std day/sea level, but it
should still be very acceptable.
Take care,
Kevin

I'd like to add that recently, Nelson which is another lakeside
airport, was threatened with closure much the same way as Meigs, however
city council listened to the many letters of support for the airport and
kept it open for at least another year.
This would be a good opportunity to show them that it is valuable
resource and source of tourist revenue. As I expect to be flying and have
test hours flown off by then, I plan to attend.
Hope to see some of you there!

Don,
I recently completed a panel re-build that included a Garmin 196 mounted
in the panel. I disassembled the yoke mount that came with the 196 and
used the plastic bracket (from the yoke mount) as a holder for the 196.
I made a U-bracket out of 0.040" aluminum (about 2.5" wide) and riveted
it to the back side of panel. The plastic holder was attached to the
U-bracket with screws. The U-bracket was bent so that the screen of the
196 would be perpendicular to my line of sight. I used a full-sized
layout of my panel and a small mirror to determine the bend angles for
the U-bracket.
The 196 is inserted into the plastic holder through the panel cut-out.
To remove the 196, I reach behind the panel and pull on the holder
release lever. For power, I cut the cigarette lighter power cord and
installed a plug that plugs into a power jack mounted on the instrument
panel support bracket.

Hi David
I am not an expert on this topic but have not seen any other replies so will
take a stab at it.
My aircraft is 0-320 with carburetor and also has a little stumble when
power is slowly applied and about the 1500 - 1700 RPM range. Only happens
occasionally, generally when leveling off from a descent. It is over before
you have time to do anything but skip a single heartbeat.
I have been told that this occurs at the carburetor change-over point
between idle and main jet and is not uncommon. I talked to Lycoming rep. at
Arlington and he suggested two things (1) experiment with linkage on
accelerator pump if it has different holes on the linkage (2) check idle
mixture for 30 RPM rise at idle cut-off.
Good Luck

| Subject: | Re: of OAT probes and NACA ducts... |
--> RV-List message posted by: "David.vonLinsowe" <David.vonLinsowe@delphi.com>
I ran into the higher than normal temps in the NACA duct too. Even with a tight,
honeycomb cowl. Because I was setting up to do some prop testing I needed
to get accurate air temps.
First the old analog gage had to go. The scale was so coarse you'd be lucky to
read it within 5 degrees.
The gage I went with is a Davtron 655. It's a digital volt meter, outside air
temp in F or C, it ties into the encoder and gives you pressure altitude and density
altitude. A little pricey, but what the heck it's in the name of science
:-)
The techs at Davtron told me the probe has to be 4 feet from the fuselage to get
an accurate reading. They told me that Cessna tried mounting the probe on top
of the windshield and couldn't understand why the readings wouldn't match the
readings from the test probe out in the wing tip. They moved the probe away
from the fuselage and the readings agreed.
I mounted the probe in the aileron belcrank inspection plate. It works great out
there. For now it sticks out in the breeze. Once the prop testing is done
it's going to be remounted with a delrin mount I turned up so only about 1/4"
will be exposed (gotta reduce that drag).

I put the probe in one of the wing inspection plates under the right wing.
Small hole drilled with the probe exposed and glued in. Seems to be pretty

--> RV-List message posted by: Stuart B McCurdy <sturdy@att.net>
We are reposting the info for the Mason City (MCW) Pre-Oshkosh Formation
Clinic 26-28 July to ensure all who would like to attend get the word.
If you know of some who would be interested but may not be on the list,
please pass on to them. So far we have a good group signed up, but
there is room for more.
The plan is to cater to inexperienced on Saturday by flying them with
experienced. Sunday will concentrate on 4-ships with more experienced
and those who have done well on Saturday. On Monday we will work
advanced formations and large formations. Evaluations will be worked in
as recommended. This will also be an Oshkosh practice for the large
formation passes scheduled for Friday, 1 August, during Showcase.
All,
Stuart McCurdy has agreed to hold a Pre-Oshkosh formation clinic at MCW
Clinic. Stu McCurdy of FFI will conduct the clinic with assistance from
other FFI flight leads.
We have a great facility with big wide runways, no tower, limited
traffic and our airport is away from the city with lots of wide-open
space. Just like Oshkosh, Bring your own tiedowns and ropes.
We have a cafe on the field for breakfast and lunch. Our airport is
situated between Mason City, 4 miles east, and Clear Lake 2 miles west.
http://www.airnav.com/airport/KMCW
We have good ramp space plus acres of nice grass for parking and
camping. There are restrooms in the EAA Chapter office and 1 shower
available in my hanger.
The FBO, North Iowa Air Service http://www.ccaero.com/, will give a
$.35 discount for fuel. Today the discounted price would be $2.30
The Headquarters Hotel will be the Best Western Holiday Lodge in Clear
Lake. They have a Bennigans bar and restaurant in the hotel. Several
other hotels are listed below. Rooms are tight act now!. Rooms
blocks are only reserved until July 11th Reservations are on your own!
Call the hotel and make them today!!!!
There will be a social registration fee of $30 per person which
includes a Saturday night BBQ and Iowa Sweet Corn feed at the Hanger and
Sunday evening meal ($20 for one night). We will need RSVP by July 23
to dougr@petroblend.com with "RV Clinic Reservation" in the subject
line. Please do not respond on the RV-List so my email program can sort
it out. Include the names of all attending and whether they are flying
formation or""copilots" This is not a hotel reservation, food and
clinic space only!!!!!
If we discover several spouses are coming we will try to organize some
spouse activities, but at this late date, that will be a shoot from the
hip operation..no promises...
We (or the hotels) will provide transportation to and from all the
hotels listed below. Again, don't look for limo quality service, but we
will get you there. There is Hertz car rental on the field.
There is a lot to do and see in North Iowa, check out the local websites
at:
http://www.masoncityia.com/
http://www.clearlakeiowa.com/
Please understand that this is being organized at the last possible
minute and some things will be fluid.
Thank you for coming to MCW! We look forward to a great event.

They are usually the lowest price for 100LL in the Columbus area.
They had 80 octane, but I think it is gone now.
Madison Co. is located about 25 miles west of Columbus about 3 miles south

Van's would still have to price the tanks close to or less than what Evan

Pretty sure his price is $975 for both tanks.

The cowl's only support is from the hinges at the aft end (connection to
the firewall). The forward end is 'free floating'. At least that's the
way the RV-6 works...

Hey Guys, I just started looking at the installation for my RV-8A cowl.
I
don't see anything that supports it at the front end near the prop hub.
Does it just rest on the baffle seal fabric? The plans show the front
of
the cowl being located 1/8" higher than the prop hub, what holds it up
there?

Lucky, I just received my SL40 yesterday. According to the SL40 owners
manual, you may activate just the pilot's mic, just the copilot's mic,
or both from the front panel. You can separately adjust the squelch for
either mic, also from the front panel, and that should take care of
unwanted noise.
You need to install a separate switch to select between the intercom
function and the monitoring of a secondary frequency.
I bought the SL40 because John Stark said that is a higher quality unit
than the xcom 760.

" 2. Both pilot and copilot mics are opened when anyone keys the PTT
circuit.
Almost all modern intercoms activate only the mic of the person speaking
to
eliminate unwanted noise."
