I have one down here in the Ventura area. I'll be transferring up to WA, and might
be able to bring it with me, but that wouldn't be until October. Or, you can
meet me half-way in the Fresno area in July, and I could bring it with me when
I hit the High Sierras. Email me off-list if interested.

Are you sure the hole is for pitot? The Katana has a hole in the leading
edge for stall indication. The Pitot is a blade under the wing.

I think the answer is no, it can not, unless the ball is stuck or not
functioning correctly, but I'm no expert.
You may want to experiment with a yaw string however to get a second opinion
from your turn coordinator. A yaw string is simply a short piece of string
secured on the centerline of your fuselage that is visible from inside. If
the airplane is slipping the string will angle off to the side indicating
the centerline of the plane is not lined up with the slipstream. Just my two
cents worth. Something to try.

Careful where you place it, though... If it's on the deck in front of the
canopy, you could get slipstream effects from the propellor, which would
push it to one side. Also, if it's too close to the canopy, you could get
effects from the stagnation point at the intersection of the canopy and the
deck.
The best place I would suggest would be on the canopy over the rear seat
passenger (far enough back to minimize slipstream yet still be visible).

Rob makes a good point. A yaw string seems pretty simple. There was one on
the T-33s that I worked on back in the 60s. But wait a minute, that was a
jet! I am under the impression that the prop causes the air over the whole
fuselage to rotate, hence the need for vertical stab offset. Uh oh, I hope this
doesn't start anything.

Steve and Weasel
The yaw string will work fine on a pusher, sailplane, or conventional twin,
but I am very doubtful that it will give a true indication on a tractor due
to the prop swirl effect. Does the turn coordinator have a true ball in a
liquid filled curved glass tube or is it a ball "symbol" hanging from a
pivot shaft in the instrument ?

I am finally at the point where I can raise and lower a (nearly)
finished tip-up canopy AND can install the seat cushions just delivered
to me from D.J. Lauritsen. (She does nice work, BTW.) I'm very normal
size - about 5' 10" and was surprised at how little room there is
between the top of my head and the canopy. Probably less than 2
inches. I certainly wouldn't want to sit lower than this for visibility
reasons. With D.J.'s booster cushion installed, there's less than an
inch, but I like the visibility. (I remember that Van's tips for
landing an RV advise pilots to sit as high in the saddle as possible.)
This was all done with the seat all the way back, which helps a bit.
I then looked at my old David Clark headset and realized it would
definitely be rubbing against the canopy because the "bridge" piece that
goes across the top of my head is more than an inch thick. The
references in the archives to headroom seem to mostly be from people who
haven't picked which plane to build yet.
So for those of you who are flying, here's the question: Do you use
headsets with very thin bridges? Which ones? Or do you all have
scratches on your canopies above your head?
On the plus side, a low canopy is probably one the reasons these things
go so fast. There's lots of compromises in an airplane design.

--> RV-List message posted by: RVEIGHTA@aol.com
All, my IO-360 has begun to run strange at low rpm after it has warmed up. I
noticed this when taxiing into the FBO yesterday - the engine would run
smooth, then it would drop rpm then pick back up again. At any thing above about
1200-1300 rpm the engine is fine.
Any thoughts about what could be the cause? Improper idle mixture adjustment
maybe? The engine should show a slight rise in rpm when the mixture lever is
brought back to idle cutoff, but doesn't, which is an indicator of idle
mixture problem (I think).

For those flying with an Altrak:
Did you hook the module into the static system or did you just leave it open?
The manufacturer directions indicate it can be done either way and I'm
looking for what other people are doing.

Hi Walt,
Just a quick thought....have you flown your plane during the "warmer"
months? I'm not bein sarcastic, the only reason ask this, is that nicely
warmed up and hot IO's (on warm days) can have a tendency to run rough at
low RPM's due to the fuel boiling before it reaches the injector. This
usually only happens with low fuel flow and goes away at higher RPM's and
Fuel flows becuase their is cooler fuel to the injectors and more air moving
through the cowling.
At first glance I wouldn't worry, but I'd make sure you have firesleeve on
all the fuel lines, especially the line from the servo to the spider (that
will help), and the line from the engine driven pump to the servo covered in
firesleeve also.
Just my 2 cents, but I notice this phenomenon (IO-360) also during the
warmer summer months.
Cheers,
Stein Bruch
RV6's, Minneapolis.

Hi all...
I decided to weigh my -8A again after the upgrades I just did... When I
weighed it after I built it I had some temporary seats installed, and did
not have the wheel pants and gear leg fairing fairings installed.....here's
what I got:
Empty weight without wheel pants and fairings: 996 lbs
Empty weight with wheel pants and fairings sitting on the wings and cowl:
1005 lbs
After a year and a half and the upgrades:
Empty weight now with interior, all fairings, new panel, and heavy starter:
1029 lbs
Still pretty light I think!
I am going to be install new "H" pistons in the next couple weeks, along
with a light weight starter. I am going to weight everything and redo the
W&B accordingly and will post the results...

Applying carb heat will richen the mixture a little. Sounds like you may be
a little lean on the idle mixture so a quick and easy way to verify that
would be to put on the carb heat and see if that improves things.

Good point. Well, it would have a a quick and easy way to check the mixture
if it had a carb!

Applying carb heat will richen the mixture a little. Sounds like you
may be
a little lean on the idle mixture so a quick and easy way to verify that
would be to put on the carb heat and see if that improves things.

All, my IO-360 has begun to run strange at low rpm after it has warmed
up. I
noticed this when taxiing into the FBO yesterday - the engine would run
smooth, then it would drop rpm then pick back up again. At any thing
above
about
1200-1300 rpm the engine is fine.
Any thoughts about what could be the cause? Improper idle mixture
adjustment
maybe? The engine should show a slight rise in rpm when the mixture
lever
is
brought back to idle cutoff, but doesn't, which is an indicator of idle
mixture problem (I think).

I hooked mine up to ships static.
In hind site, I would not.
I have had my static get water in it in heavy rain and clog the system.
Delivering erroneous results while IFR. Yuk!. Has happened to me twice
and neither time was any fun partial panel woth static blocked with a
drop of water.
I have since installed a quick pull device to vent ships static to the
cockpit. My fix on that is in the archives. Simple I have a small piece
of r/c fuel line with an r/c bulkhead fitting, 1/8 inch. Through the
panel. When I want an alternate static, pull it off and presto, venting
to cabin.
But I do not think there is any up side to connecting the Altrak to
ships static.
There is a down side to doing so as my experience dictates.

Before, I worked out most of the heat issues on my plane. It would
sometimes run rough and even quit once during the taxi back. Now when I
hear the first hint of roughness, I turn on the electric fuel pump and the
additional pressure seems to keep enough pressure inside the fuel lines so
that they don't "vapor lock". It is worth a try. Good luck.

I asked the folks at TruTrak about this and they said that the accuracy is
better with the static connected. As I recall the difference was plus or minus
20 feet. I could be off there.

--> RV-List message posted by: "Harvey Sigmon" <rv6hes@comcast.net>
Tom: I will give you my humble opinion on canopy clearance. Background
information on myself, I am 6'4" a Bubba size frame, tall in the waist
flying a RV-6, my first RV-6 was a tip up canopy, my solution was use the
back hinge position and do not use the seatback upper securing attachment,
let the back of the seat rest on the cross channel. By doing this it gives
you a slightly recline position and for me that give about 1" clearance
using a David Clark headset. I did not notice and rubbing of canopy, but in
turburelent air you must keep the shoulder Harness snug or the head could
hit canopy. On my present RV-6A with a sliding canopy I have about the
same clearance as the tip up but it seems the seat back is slightly forward,
not as comfortable as the tip up position. The seat cushion is the normal
1" temple foam, but the back rest has minimum thickness. with your height
it should be a piece of cake, but you might need to shop for a head set that
does not have such a thick headband.

The placement of the pitot tube in the flow field around the airplane should
not matter much. According to theory, any local increase in the velocity of
the air (due to the shape of the wing, for instance) will cause a
equivalent decrease in local static pressure so the total (static plus
dynamic) pressure will remain unchanged. If this is compared to an accurate
static pressure source, the difference is then dynamic pressure which is
then fed to an ASI or whatever to show an airspeed indication.
The reason for the long, skinny, forward-projecting pitot tubes on some
aircraft is to move the static vents on the pitot head clear of the flow
field and get an accurate static pressure reading. If the static pressure is
sensed elsewhere, then no need for this. Look at an F-86 sometime, the pitot
tube is buried inside the engine intake duct and works fine (some models
anyway).

Walt: A leak in the intake manifold will make it run irregular at low
speeds, also clogged fuel nozzles will sometimes cause the engine to run
irregular. As you noticed above 1200 the fuel schedule is more consistent,
and most fuel injected engines the fuel servo meters much better above idle.
Check fuel pressure, clean fuel nozzles and maybe even clean main fuel
screen if it is a Bendix Servo. As some listers have said if the engine is
hot after starting they will run irregular until you get clean fuel to the
engine. My view only hope this helps.

I am 5'6". I also have DJ seats with the booster and the child cushion. At
first I only used the booster, but was not making the best landings. I then
tried the child booster cushion and my landings greatly improved.
I still have about 1" clearance between my head and the canopy. I have
bumped my head 2 or 3 times in very turbulent air. Really not too much of a
problem in the seatbelt and harnesses are sinched down.
Van is correct in assesment of sitting a tall as possible.

--> RV-List message posted by: "Cory Emberson" <bootless@earthlink.net>
Hello everyone!
With Matt Dralle's blessing (thank you, Matt!), I'm pleased to post this announcement
for a terrific aviation fly-in weekend. SMXgig (in Santa Maria, CA) has
become the year's largest face-to-face get-together of electronically networked
aviators. We hope you'll plan to attend because we expect this year's gig to
be the best ever.
People come from all over the country (and sometimes overseas) to attend, and most of the sessions qualify for FAA Wings cards. The dates are 4/30-5/2/04 (Friday-Sunday) - it's a lot of fun, and a great chance for pilots from all over to mingle and share aviation stories, ideas, etc. The announcement below contains most of the crucial information, and you can get the rest from the website (www.smxgig.org). If you have any questions at all, just let me know, and thanks!
~~Cory Emberson
KHWD
>>> NOTICE TO AIRMEN! <<<
Announcing the Sixteenth Annual SMXgig
to be held on April 30 - May 2, 2004
at the Radisson on the Santa Maria (CA) Airport (aka SMX)
www.smxgig.org
SMXgig will be April 30 - May 2, 2004, at the Santa Maria Radisson. This year,
our featured speaker after Friday night's dinner will be Rod Machado!
"MACH 2 WITH MACHADO" is the byline Rod Machado has earned for his rapid fire delivery
at his lively safety seminars and keynote speeches. His programs are information-packed,
energetic, and humorous. He has spoken in all fifty of the
United States and in Europe sharing his fresh approach to aviation education.
If you can make it, please do. It's going to be pretty special. More information and the announcement/ registration info is available at www.smxgig.org You may also contact me by email at: cory@smxgig.org.
All technical sessions will be held in the Enterprise Ballroom at the SMX Radisson.
Each session will last about an hour. We schedule four tech sessions on Saturday
morning, and four on Sunday morning. Most of the speakers are set (I'm
still firming up a couple of slots - I'm working on a session about Experimentals):
MIKE BUSCH - The Art and Science of Troubleshooting
Your A frequently, that person is you. That's particularly true of problems that
occur only in-flight and/or are intermittent. This session offers methodology
for troubleshooting aimed at aircraft owners who aren't A&Ps.
ED WILLIAMS - GPS - How It Works, and How to Work It
Ed is a nuclear physicist working at Lawrence Livermore Labs. Ed does a
remarkable job of making physics phun!
BRENT BLUE, M.D. - Pilot Medicals: How to Avoid Problems with the FAA
Brent is an AME Advocate, who specializes in helping the tough cases renew their
medicals. He's a former member of EAA's medical advisory committee.
DOUG RITTER - Equipping Yourself To Survive - Personal Survival Gear for Pilots
Doug is a survival evangelist, personally driven to help pilots live through whatever comes next. www.equipped.org
PAUL MILLNER - The Future of Avgas
Paul works with ChevronTexaco, and is right in the middle of the industry developments
regarding our fuel of choice.
MARY DUFFY & UWE LEMKE - Flying in Europe
Mary and Uwe are a Scot and a German who live in the San Francisco Bay Area, but
return "home" often.
As always, each qualifying session will get you a WINGS Safety Session card.
Our Saturday evening event should be a delicious one! At 5:45 p.m., the BFUB (Big Fat Ugly Bus) will arrive at the Santa Maria Radisson to bring us to the Far Western Tavern for dinner in beautiful Guadalupe (www.farwesterntavern.com).
DOLLARS AND CENTS
Just as in previous years, there will be one flat all-encompassing "gig" fee that
covers all events that involve significant out-of-pocket costs for the organizers.
The fee is $160 per person, and will cover:
- Friday afternoon welcome party
- Friday evening dinner banquet
- Saturday and Sunday tech sessions
- Saturday afternoon lunch
- Saturday evening dinner at the Far Western Tavern in Guadalupe
- Meeting rooms and coffee service at the Santa Maria Radisson
- Transportation to (and from) the Far Western Tavern
Lodging at the SMX Radisson will cost $89.00/night for either a single or double
room, which is far below the regular hotel room rate. Be sure you check in as
a SMXgig attendee and get the special rate. We have our definitive preference
listed with the hotel for rampside rooms - early registration can only help,
but of course, the rampside rooms are subject to availability depending on how
many existing guests are in those rooms.
You do not need to register with the hotel - just give me your preferences, and
I will take care of the reservations.
Important: This year, our final rooming lists are due to the hotel on April 11,
2004 (the even of Sun 'n Fun), which will guarantee space and the group rate.
The hotel will accept additional room reservations after that, on a space- and
rate-available basis. They will try their best to accommodate us after that
date, but the hotel is already sold out for the weekend.
The website (www.smxgig.org) has detailed information about the schedule, meals, hotel accommodations, and online registration. If you'd like your own announcement/registration emailed to you, or have any other questions, just let me know. (cory@smxgig.org or bootless@earthlink.net ).
Thanks, and see you there!
best, Cory Emberson

Ok, so if I understand correctly, a hidden pitot with the front flush with
the leading edge and a static source on the side of the fuselage should work
just fine. (All theory of course) So the next question would be....if I
figure out how to heat the pitot with an element like the one in my standard
heated pitot.....is this a problem in a confined space? We are no longer in
200 mph wind. How are these things thermally regulated?

To answer the original poster, yes, at 5' 9" it is a problem, and I do have the
aforementioned scratches all over the inside of the canopy, over my head and
the passenger's head. It's not an area of the plexi you look through very often,
maybe during a roll if you want to get woozy, but it is noticeable when looking
in from outside on the ground. I have Lightspeeds, which have a very thick
padded headband.
I'm very interested to hear what Larry says about product performance with the
in-ear headset he uses, in particular boom mike stability issues. I have had
the Lightspeeds come off my noggin when pulling G in a turn and leaning my head
back to look for the guy I'm dogfighting. Has happened several times in fact,
So I am curious how well an ear spud can stabilize a boom mic in the aircraft
environment.

<<I am 5'6". I also have DJ seats with the booster and the child cushion. At
first I only used the booster, but was not making the best landings. I then
tried the child booster cushion and my landings greatly improved.
I still have about 1" clearance between my head and the canopy. I have
bumped my head 2 or 3 times in very turbulent air. Really not too much of a
problem in the seatbelt and harnesses are sinched down.
Van is correct in assesment of sitting a tall as possible.

I got mine last year at OSH, $325 I think? Stereo. They perform well
and are very comfortable. As if I'm wearing nothing at all....on my
head, that is. I have the generic foam plugs. You can get custom ear
molds too.
On the downside, they are a little tricky to get positioned exactly
right-- the placement in the ear determines where the mic boom ends up.
Sometimes the mic is just right, other times I have to try again. They
can also be pulled out of adjustment if I turn my head far and the cord
catches on your collar, for example. But these are minor annoyances,
IMO. I like 'em. They are the only headset I've used since OSH last
year (but I still have my David Clark's too).

The in-your-ear headsets may have issues in a dog-fight type scenario.
Lots of extreme head movement and big G's will like take it out of
'alignment'. But for more sedate flying and hours of cross-country,
they are perfect.

I don't have a picture, but I can tell you that mine was absolutely
beautiful and the quality and service from Ed is top notch. I have called
Ed on the weekends before. If you call him tomorrow I bet he has some
pictures he can send you.
I had mine done with alternating laminations of cherry and maple, or was it
cherry and birch? It really added a lot to the appearance and didn't cost
any more.

| Subject: | Re: hidden pitot tube |
--> RV-List message posted by: Kevin Horton <khorton01@rogers.com>
I'm not convinced that it is quite this simple. I suspect there are
at least two potential issues:
1. There should be some energy lost in the boundary layer, so the
pitot pressure may not be quite as high as it should be.
2. The stagnation point (the spot on the leading edge where the
velocity comes to zero) moves as the angle of attch changes. So I
think any hole location would only work properly at one angle of
attack.
If it was so simple to use use a hole in the wing leading edge,
manufacturers wouldn't be spending money on pitot tubes.
It would be an interesting science experiment to have a normal pitot
tube, and a hole in the leading edge, each hooked up to an ASI. Then
we could compare the readings from the two different pitot locations.
I would be very hesitant to use a wing leading edge hole as my only
pitot source until we can find definitive proof whether it would work
properly or not.
I would love to see a good picture of the F-86 pitot source that Jim
Oke mentioned. Is it a somewhat conventional pitot tube inside the
engine inlet? If so it would sidestep the boundary layer and
stagnation point issues I mentioned.

I'm surprised that no one has metioned Peltor. They have a very thin

Tape a several strings about 6 inches long each across the top of the engine
cowling - they will show local airflow, which will probably be
affected/modified by the spiraling prop wash. We had a single yaw string on
the nose of the F-84F which was quite informative - of course we had no prop
to "modify" the straight back flow of air. It was good for showing yaw.
On a tractor prop plane, starting with several strings may reveal that 1
particular one would be best - might even try taping a second row on the
front area of the canopy - further aft from prop - but airflow will be
"splitting"/going around the canopy so don't know how true the reading will
be. See how the strings compare with the slip indicator. You might find a
combination that gives you confidence that you are flying straight.

At 6'3" using Peltors I have no problem with head room. Yes I am close
