A question - why does the alternator need a switch that is separate from
the master? I cannot think of any time when I would want one without the
other.
You would always want the battery switch on if you had the alternator on, but
in the rare case that the alternator "runs away" and starts putting out
excessive current you can shut it down without shutting off the main buss.
That's why the "Cessna" master/alternator switch (the double red one) is
keyed so the master can be turned ON by itself, or the alternator OFF by
itself, but not the other way around.
Incidentally, I was at the first flight of Ken Hitchmough's RV6A, and I have
since been for a flight in it - it is fabulous. My workmanship is not of the

I started with about 1 1/2 inches tall in front of cylinders 1 & 2 and went
to just over 3 inches. The 3 inch "dams" increse CHT on the front two
cylinders 50-75 degrees. I remove them in the summer. Still, at reduced
throttle settings, CHTs are a little uneven. At full throttle cruise (at
7,500 or above, 2560 rpms) CHTs even out pretty good, within 50 degrees of
each other. Bob Skinner RV-6 BSkinner(at)ltec.net

The builder's manual includes a list of all the tools needed, and John
Hovan's page links to a list of all the tools you could possibly use.
Somewhere between these two is the probable reality, dictated by your
money, skills, and preferences. I ignored Avery's 'kit' and made up my
own (Avery will give you discounts for spending enough money), based on
the tools I needed to complete the tail kit. Not only did this let me
get started with less money, but also left me with fewer tools to get
rid of should I abandon the project. However, the bug has bit, so I've
bought the rest of the tools I need. Also, what you need depends on
what you already have. In short, you'll have to decide for yourself
what to buy. IMHO, the more power tools, the better.

BestBillo; I've got the same. From asking others over the years, and
somewhere in there a word from Vans, is that it's 'normal'. I don't like
it, because as you say, the 'reversal' when trimming, but I haven't been
able to figure out a cure for it. My trim tab has about 3/8 to 1/2 inch
play in it, and as you move it, you can see the cable moving back and forth,
that is why I feel that the slop is in the cable/vernier part. If I reverse
my trim desire in flight, I just automatically rotate about a full turn and
a half before it takes a bite on trim. If you come up with a cure, let us know.

Ed's comments are true but I would caution readers not to depend upon
an alternator control switch as the primary means for controlling a
runaway alternator. When a regulator goes south, voltages on the bus
rise in MILLISECONDS . . . . Given proper ov protection, you'll never
see an OverVoltage lamp turn on. The alternator should be AUTOMATICALLY
shut down so the first light you'll see is the LowVoltage Warning lamp.
This design and fabrication philosophy should put your worries so
far removed from possibilities that ganging alt and battery together
is an entirely appropriate thing to do. Pullable ALT FLD breaker
is a useful maintenance tool for killing the alternator.

The FAQ has a pretty good list. To sum it up:
1. Avery's big tool kit
2. Drill bit stops
3. 15 or so cleco side clamps -- some of both sizes
4. Lots of Sharpies
5. Riveters tape
6. A back rivet plate of some sort
7. Jewelers files for cleaning up edges of sheared aluminum
8. Small (1-inch and 2-inch) Scotchbrite wheels with mandrel for same
9. Assortment of woodworking clamps
10. Decent touch-up spray gun
11. Fan rivet hole marking guide
I also bought a floor-stand drill press, and I love it. When it's not being
a drill press, the table is being an adjustable height work area for
supporting the opposite end of long parts that I'm working on.

I believe 30 deg up and down is called for. I'd build and place the horn to
spec. One of the Rockets I built had this option, and it didn't seem to have
enough trim on short final (these birds are nose heavy anyway). I adjusted
the tab for proper travel in the nose up direction, and this left less nose
down. Still no good, so I made up a different tab, similiar to the tabs on a
V-35 Bonanza (extended chord), and this fixed the problem. The different tab,
with separate top & bottom skins, was much easier to build, BTW.

I know everyone must think this has been beaten to death by now, but I
had an idea I thought I'd share. The instructions say that one could
use Proseal instead of RTV to strengthen the surfaces if one had a
builder close by with some to spare. I'm thinking that I will put
Proseal between the stiffeners and the skin as well to strengthen this
area. I understand it's quite a good adhesive, and this seems to be an
application where the extra strength would help. If I can't scrounge
some, I'll order it from Van's. By the way, on drawing 7PP on the
RV-8, it looks like the clearance is about 5/16 between the stiffeners
and the trailing edge at the closest point when you transfer the scale

The GPS system is being augmented with a system of ground monitor
stations, a few master stations (I think 2 of them), and the use of
maritime satellites (INMARSATs). The ground monitors will monitor all
of the satellites for proper data, relay the information to the master
stations, which condense the data and relay it to the INMARSATs for
retransmission to all users (GPS receivers). The idea is that all GPS
receivers will be able to receive system integrety messages (eg.
Satellite #17 is transmitting bad data, don't use it).
Additionally (I think), the INMARSATS are being fitted with GPS
transmitters, so that they can transmit the standard GPS data for use
in navigation, thus increasing the number of satellites in the whole
constellation.
The whole thing is called the Wide Area Augmentation System, or WAAS.
That is all.

under FAQ, the question about occasionally exceeding the 2600RPM restriction
was raised. Sensenich's statement is simple: You absolutely must not exceed
this limit. With this in mind, I calibrated my ISSPRO mechanical tachometer
with the aid of an electronic handheld tachometer. The mechanical tachometer
read low in all ranges, from 50 RPM low at idle to 150 RPM low at a static
RPM of 2250. Interpolating from this, I will redline my tachometer at 2400
RPM. I also hope to repeat that test in flight at cruise RPM, and will

Mark (I think this is from you & not Matt),
First of all, I'd spend another $ 240 and get the pneumatic squeezer.
Some other items that are great to have: a hand held belt sander. This is
much faster than files. I also use the belt sander to smooth the rough
shear edge before I use another item that is handy, the double edge
deburring tool. You'll need a flat, smooth piece of steel for back riveting
stiffners (back rivet plate). The jig fixture brackets are handy for
speeding the project along but at $ 21.00, it would be nice to borrow a set
from your fellow builders (see below). The right angle drill attachment for
$39.00 will come in handy. I also use my Scotch-Brite cutting and polishing
kit quite a bit. Buy the same diameter sandpaper discs for use with the same
mandrel. A cheap right angle air drill is handy for use with the above. I
use both the medium and fine 6" Scotch Brite deburring wheels, heavy work on
the medium--finish off with the fine. You'll need some Sharpie marking pens.
Some stuff you could save some money on: drill stops, wrap masking tape
around your bit, instead. Fan space rivet tool, the new kits are predrilled
and there is a cheaper way to accomplish the same thing, anyway. I see the
kit comes with a straight flush set. A lot of builder's are using the flush
swivel set and this does virtually eleminate smileys. I have and use both
but have been using the straight set more and more as I feel it's smaller
head transmits more force to the factory head and less to the surrounding
area. It seems like I get a better job of riveting done with the straight
set, maybe just my imagination. The swivel set is probably a good idea if
you're bucking and have someone who is less experienced driving. (I bought
the swivel so my wife (and me) would be less nervous)
If I'm directing this reply to Mark, if you'd drive to Lexington (and
bring, you know what) I'll give you some further pointers, we'll practice
riveting and I'll give you a RV-6 ride. Bob Skinner RV-6 BSkinner(at)ltec.net

I think limited advertising on this list is fine, so long as it meets two
criteria.
1] The item or service is of direct interest too, and specifically for RV
builders and pilots.
2] It is honest and free of scams.
If someone on this list has developed something that can help other builders
why not talk about it? And, if it costs money, so what? Everything costs
money. I don't expect someone to build a tool or a part for me for free.
Perhaps if that person was my neighbor, I'd invite them over for dinner as a
token of my appreciation for the time they spent on my part. But obviously,
if that person is 1000 miles away, that invitation might be inconvenient. So
instead, I send a few buck so he can get himself a meal in his own town. What
wrong with that? Money is not the root of evil. It is simply our medium of

Oooh boy, I bet this will be a veritable can o' worms! I considered posting
this privately, but I'm sure others are sitting on the fence as well, so
here's my .02:
Mine is a slider and I wouldn't even consider building a tip-up. My main
reason is cosmetic. I just LOVE the way the slider looks and the
silky-smooth operation of it. It's very fighter-pilot-esque, and oh so
jaunty (not to mention a nice breeze) to taxi with the slider back and your
arm on the side rail.
As for the cons, the instrument panel can only be accessed from underneath
once the top skin is riveted on. I believe it's also a little trickier to
build.
These are MY opinions. Lots of people like the tip up - I just like the
slider better.
Happy decision-making,
Ed Bundy

Well, hopefully he'll learn. I remember at one point George and Becki, around
the time they got on the list for the first time, seemed to answer everyone's
questions with (roughly paraphrased) "Buy our tapes, it shows you right
there." but now they are excellent list-citizens and we'd be much poorer
without them.
I think there are two times when an ad like the first (Although without the
Ronco-like sales pitch) is appropriate. First, when a product or service
first becomes available. And second when someone specifically asks for it.
Perhaps Matt should add an advertising etiquette section to the message sent
out to new listers.

Mark, You never heard of the "poor man's rivet spacer"? It's free. Also,
as you said, the new kits are pre-driled. I'd apply the $ 36 ? to a
pneumatic squeezer.

Well, some builders swear by it, but I find it cumbersome to use,
and can scratch unprotected surfaces (I had an early kit withhout the
plastic protectors on the alum. sheets)
So, crass commercialism or not, I will sell mine for 50% of the
current Avery price (plus $3.50 shipping).
It's in good condition (it is stainless) and was made by the
original inventor of the tool - Kit Aircraft Tools, Lawndale, CA - now no
longer in business. It appears identical (can you say copied? ... :^) to
the current Avery model.
So, if you want one, save a few bucks, $19.50 plus $3.50 shipping.

Of course, there are other options if you want to get inventive. I think

Subject: | Wrecked Bonanza parts |
Guys --
A friend of a friend destroyed his Bonanza in a microburst incident 2 years
ago. (Neither occupant was killed.)
He has the option to purchase the wreckage from the insurance company at
what *sounds* like a pretty good price. He would do so in order to
salvage some of the avionics he wants for his replacement plane -- like the
StormScope -- and would sell everything else.
I would *think* this would be an opportunity for me (or other listers)
to pick up a whole ton of items, such as:
1. Lots of radios and such
2. Engine instruments
3. Heated pitot tube
4. The electrical system parts -- the bus, master switch, other
switches, etc.
5. Exterior lights -- strobes and such
6. Misc stuff like Hobbs meters, etc.
However, I don't know how likely this stuff is to survive this kind of
accident. It occurred during missed approach -- they bellied into the
ground, nose high, full engine power, and totally destroyed the aircraft.
The seats, occupants still attached, separated from the fuselage, for
instance.
I also don't know how I would be able to test if it worked, what the
damage to stuff is if it sits for 4 years (2 years since the crash and
another 2+ years until I'll be in the air), or what fair prices might
be.
Comments?
If he buys the wreck, should I do a followup post with the available
items?

I didn't see any other responses to this, so I'll toss in what I know.
Approximately a year ago, an early RV-3 was destroyed in flight. The
plane in question was being flown in close proximity to Van in one of the
factory planes at the time, making the incident even more poignant.
>From bits and pieces I have heard, and some of this information might be
confusing multiple incidents or just plain wrong -- please don't jump all
over me for that -- here is some info.
1. Early RV-3s had a fairly low stick force per G factor. That is, as
you added Gs by pulling on the stick, there wasn't a lot of force
telling the pilot what he was doing. This increases the ease with
which one overstresses the airframe.
2. RV-3s (maybe only early RV-3s) have been shown to fail earlier than
structural analysis suggest they should. Van has identified this as
a problem and provided a fix free-of-charge to all registered RV-3
owners.
3. The pilot of the failed -3 was, if my info is correct:
a. NOT the builder and relatively new to the -3.
b. A medical examiner for the military, used to high-G maneuvers
riding in fancy military hardware. A 9-G turn wouldn't be
unusual to this sort of person.
To the best of my information, this is the only known RV- in-flight
breakup, and it was an early RV-3. The contributing problems in the
-3 do not appear in the -4, -6, -6A or -8.

They are in fact different. Vans are designed for the normal tires,
Saviers require the smaller "lamb" tire (RV-6A nosewheel tire). I do
like Savier's wheel pants, they LOOK fast. Saviers do appear to me to
be a fair bit thinner and lighter than Vans.
BUT... since I plan to USE my rv, i.e . fly it into grass, dirt &
gravel strips, I'll probably pass on the fancy wheel fairings and small
tires. (This might also have something to do with the fact that I
trashed Ken Scott's fancy wheelpants after the air pressure got a little
low and I bounced it kind of hard....)

Subject: | Where to put the electrical conduit in RV-6AQ |
I'm looking for advice/experience regarding where to locate conduit in my
RV-6A (quickbuild). I bought 50' of Van's conduit (light weight, ridged,
approx 7/8" OD) which I intend to use to house electrical lines running
thru the wings (I gave up on the small factory-installed grommets because

way to run the conduit is right down thru the lightning holes in the main
ribs (behind the spar). The largest lightening hole looks like a good
candidate -- it matches the hole already cut in the fuselage right behind
where the main spar will go. I need to make sure, however, that the
location I pick doesn't end up interfering with the aileron pushrod that
also runs thru the large lightning hole.
Is there a location (top, bottom, front, or rear) inside the large
lightning hole that would accomodate the conduit without interference
from the pushrod? Should I drop back to the second lightning hole behind
the spar, and open up a new hole to the fuselage?
Thanks for your ideas and experience.

I don't agree that this is a good idea. If we were building Murphy's and
some of us were doing biplanes and others were doing SuperRebels,
maybe. But there are enough similarities between the -3, -4 and -6 and

one other model and maybe all of them.

Tim,
I would be very leery about putting anything "in" the first big lightning
hole in the main ribs. If anything came adrift in here it would be muddled
up with bell cranks, pushrods etc. I drilled a hole in the metal between the
top of the spar and the first lighting hole. This is a location I have seen
successfully used in completed aircraft. There has been some discussion
about alternate locations and the archives may be worth a look. A useful tip
(from the archives) is that a piece of dental floss with some rag tied on
the end can be blown down the tube easily with compressed air to provide a
pull through (and leave one in place).

The Lamb tire is a smaller diameter tire, but it fits on the 5x5 cleveland

I'm not sure if the carb air hole can be considered as "alternate air".
My inspector wanted me to put something AFTER the filter. I didn't want
to put another cable into the cockpit so instead fabricated a hinged
door in the bottom of the air box in the centre of the filter and
spring loaded it in the closed position. The theory is that if the
filter gets totally clogged or a bird goes down the thingamy, then the
reduced pressure will pull open the flap and supply air to the carb.
Thats the theory, now whether or not it would work is another story. In
reality I've got the spring rather tight so it will probably never open.

One of the problems with Van's tubing is that you have to have it in
place when you rivet on the last wing skin surface. If you've already
run the tubing down the wing, it may be in the way when you rivet on the
skins.
I used a piece of thin wall PVC tubing that could be slid into the wing after
the skins were riveted in place. I positioned it near the top
skin behind the main spar. Some people are putting this tube in front of
the spare so that they don't have to feed the wires throught the spar box
inside the fuselage.

Absolutly not if you plan on flying IFR...... The regs say that you
need something like 20C rise in ambient for alternate air ( They don't say under
what conditions). I found that the lower cowl air was not
sufficent as alternate air in IFR conditions, so I put a muff around the
cross-over pipes just above the airbox. a short hose is used between this
muff and a new hose nipple on the airbox. Early tests still indicated
that the air wasn't hot enough, so I wrapped a door sping painted with
high temp paint around the pipes under the muff to increase the surface
area. A temp probe in the airbox now indicates the needed ambient rise
in temp. I've not seen any indication of icing since.

The air box is large enough to handle ingestions of this sort. The air

If that little birdie can get in far enough to block the inlet and
carb heat flap, you have a problem. The same is true if you ice your
filter on a fuel injected engine where heat is not supplied to that
flap (alternate air).
I have a problem believing the icing bit. A local inspector did not,
so one local builder had to put another inlet door between the filter
and the servo inlet. This will take care of the birds too.
Not wanting to get caught at inspection, I put a door on the oval
plate that bolts to the servo (part of FAB). There will be a light
spring holding the door closed. Should the need arise, the pressure
differential between the cowl and the intake will open the door.
Setting that spring up so that the door is normally closed promises to
be fun.
The area of these alternate inlets may be less than the carb or servo
throat. I figure that if you are in a position to need these things, a
slightly starved engine will be enough to melt the ice or get you and
the unfortunate bird home. Once again it is nice to have an aircraft
that performs as well as the RV's do.

Hi Mike,
Well, the truth of the matter is that Majordomo (the list manager software)
basically just isn't all that great. It was free and it's a lot better than
just using a basic email alias, but it gives me gray hairs.
The problem you were having is that you were listed as follows in the
RV-List address list:
MIKE_PARKINSON(at)HP9061.desk.hp.com (Mike Parkinson)
Unless you unssubscribe with that exact string, majordomo doesn't have
a clue as to who you are. I notice that the address you are signed up
as bears little resemblence to the one you sent me mail from... ;-)
Your message to me about this has a From: line that reads:
MIKE_PARKINSON@HP-Australia-om1.om.hp.com
In the future, here's how you can more easially unsubscribe from a
majordomo run email list like the RV-List and Zenith-List.
Step 1: Send an email message to "rv-list-request(at)matronics.com" and put
the word "who" in the body of the message - no subject and
no other text. Majordomo will send you back a list of all the
email addresses currently subscribed to the List. Best of all,
the address will be the exact syntax you will need to successfully
unsubscribe.
Step 2: Find your name/email address in the list and send another email
message to "rv-list-request(at)matronics.com", this time putting
the following in the body of the message and no other text:
unssubscribe
Step 3: In a few hours, repeat Step 1 and verify that your address has

Yes, as already stated, you should be using it for hole spacing only, not
edge distance. The spacer is placed over your drawn rivet line to space the
rivets. Also, pull it longer than your spacing and compress it back to your
needed rivet spacing as it is more accurate if compressed to the measurement
than pulled out to the measurement. (Did that make sense??)

I mounted a 2 inch flair to the top of the box for a scat tube from the carb

Subject: | converting to C/S prop |
I'm converting an IO-320 engine to use a C/S prop. In order to do
this, the large plug in the end of the crankshaft has to be removed,
and the smaller plug inside of the crankshaft has to be replaced
because it has been punctured in order to use a fixed pitch prop.
Question, what is the best way of removing the plugs? Does anyone
on the list have any experience on doing this? I've already purchased
the small plug that will go inside of the crankshaft, and I have a
copy of the Lycoming service manual for my engine. However, all it
says is to "remove plugs". It's not very specific about how to do
this. Also, it calls out a tool to use for seating the small plug. Is
there an alternate tool that I can manufacture to do this?

Have you plumbed the return line (not the overboard vent which goes onto the

the dipstick tube and install the hose fitting there? Or where else? A
local Lancair builder incorrectly plumbed the return line to the 3/8" FNPT

from the case filling up the separator, so that can't be right.
Is tapping the current plastic dipstick tube (appears to be .187" wall thk)

If you get flamed I will be very surprised - your start on the path of
the RV brings you into the very spiritual center of this list. This
list is not just about the transfer of knowledge, the sharing of
tricks, and the opportunity to tap the vast technical expertise of
other list participants; it is also about the transfer of
encouragement, the sharing of emotional support, and the opportunity
to tap our collective human character via these cold flickering
phosphor dots to help you and the rest of us keep making headway.
Well, that and the ads.
The human stories of determination and adversity, mistake and genius,
and finally success are the best of this list. The reason we all do
this is that we share a dual passion - to create, and to fly. The
technical details are the means to serve our passion, but getting up
there in something we built is always the goal.
Don't get me wrong, I'm as much into the technicalities as the next
guy, but we're not building go-carts here - these are _airplanes_!
I have been lurking here for a while now, and one of the reasons I am
still here (and one of the MAJOR reasons that yesterday I put in my
first Avery's order preparatory to ordering my first RV-8 kit) is the
uniquely human character of this list. The folks here are people, and
they have no problem sharing with others who share their dual passion.
Contrast this with other venues with similar potential
(rec.av.homebuilt for example, where the primary pastime seems to be
shooting down ideas and the people who have them) and the uniquely
human character here becomes all the more evident.
And after all that if you DO get flamed - well, they (like me) are
just jealous.

Just can't resist sharing a sea story.
Ya know how Cessena has the vent intakes on the leading edge next to the
windscreen? You guessed it. At a younger age I was prone to using aviation
to lure those of the fairer sex out on scocial engagements, I know I'm
probably the only one here that has thought of it. Well, on one occasion I
happened to lure a young lady that was excessively easy on the eyes. The
dashing aviator thing was going as planned, then just as I leveled out at
one thousand; splat. I looked over and her white sun dress is covered with
bird goo. She freaked, and demanded that I land. While tying down the plane
I found the aft section of an unlucky sparrow crammed in the vent hole.
As it was clear that aviation (and me) had ceassed to impress her, I just
told her "aw, that's nothing. Just be glad it was'nt a turkey buzzard, it
takes forever to clean up when you hit those."
Boy, can I digress from a string. You were warned.

Andy, your right. I have been thinking about each and every reply in this long
string. I did't have a particular opinion about advertising on the RV-list, but
I ,too, was annoyed at the advertisment that prompted so many replies. I
believe that most of us (including Elon O.) would never have had a problem
if we percieved the engine(s) being advertised as a reasonable offer.
But, when someone tries to sell an engine whose 1:reputation is
clouded(H2AD), deservedly or not, 2: Tell us it has a zillion hrs. but can
give us a zillion more, and 3: tell us all sales are final, the offer
becomes tainted.I have been on the list for 5-6 months and have not seen any
other adv. that evoked the response we saw last week. And, there have been
plenty of little ads and offers
and even a few very big ads (such as completed RVs for sale). In the end, we
really do want and need some form of advertising on the list. But, as you
and several others have suggested, the products must be desirable and
offered respectfully and in good faith......... Yes, Andy, your statement
says it all.

Subject: | Alternator On/Off Switch |
Following the recent thread about alternators with interest and I have some
pre-conceived ideas about alternator switching, those of you with more knowledge
may be able to set me straight.
It has been my understanding that automotive alternators are inoperative
(switched off) when the ignition key is in the "start" position. I read
somewhere that this is to keep the little alternator from getting a hernia
trying to bring the system voltage back up to 14 plus when the engine is
cranking.
It is also my understanding that when the automobile engine is stopped and you
want to listen to the radio you use the accessory position of the ignition
switch. This position does not send power to the alternator field. Again, we
don't want the alternator field circuit telling the alternator "get busy and get
that voltage up".
The same scenario happens on shutdown, automobile key off, engine ignition and
alternator field power go off together - on our aircraft mixture is pulled out
and the engine stops, and until the master switch is turned off alternator field
circuit screams at the alternator to "get that damm voltage back up!"
Another reason for some form of alternator control, be it switch, circuit
breaker or whatever, is to reduce the electrical load in the event of a
alternator failure. One example - if the alternator drive belt failed you would
want to shut off that pesky screeming alternator field circuit because it would
be shouting "give me more juice and I will get that voltage back up for you".
Anyway it is my understanding that automotive alternators do not get as many
hernias as aircraft alternators and actually live longer.
In my case alternators may be obsolete by the time I get to my electrical
system, however if I do use a alternator I will plan a control switch and
automotive type fuses. My alternator will remain off until after engine start
and be shut down before the engine is stopped.
Now go ahead and make your day, I really need the info.
Thanks

It has been my understanding that automotive alternators are
inoperative (switched off) when the ignition key is in the
"start" position. I read somewhere that this is to keep the
little alternator from getting a hernia trying to bring the
system voltage back up to 14 plus when the engine is cranking.
It depends on how the ignition switch is wired along with
other considerations about the engine systems management
functions built into the computers under the hood. Actually,
at least from an airplane perspective, it matters not whether
the alternator is on or off curing cranking. The thing
only uses a couple of amps compared to hundreds of amps
by the starter. Further, it puts no unusual stresses on
the alternator . . .
It is also my understanding that when the automobile engine is
stopped and you want to listen to the radio you use the
accessory position of the ignition switch. This position
does not send power to the alternator field. Again, we don't
want the alternator field circuit telling the alternator "get
busy and get that voltage up".
It isn't just the alternator. Fuel pumps, ignition systems,
some cooling fans, etc can run in the IGN ON position that
are disabled in the ACC position. The consideration is
not one of taking care of the alternator but one of reducing
standing loads on the battery to a minimum.
The same scenario happens on shutdown, automobile key off,
engine ignition and alternator field power go off together -
on our aircraft mixture is pulled out and the engine stops,
and until the master switch is turned off alternator field
circuit screams at the alternator to "get that damm voltage back up!"
No big deal . . . the field current rises to it's max
value of about 2 amps. If allowed to stay in this
condition for too long (no cooling air) you can overheat
the field winding but we're talking about tens of minutes
before things get really hot.
Another reason for some form of alternator control, be it switch,
circuit breaker or whatever, is to reduce the electrical load
in the event of a alternator failure. One example - if the
alternator drive belt failed you would want to shut off that
pesky screeming alternator field circuit because it would be
shouting "give me more juice and I will get that voltage back
up for you".
Same, same . . . with broken belt (no cooling air) why
waste a limited resource (battery) on keeping an alternator
warm? In case of a passive failure of this type, you need
to reduce loads on battery to a minimum. In my designs
this included shuting off the battery contactor. That
critter draws about an amp all by itself . . . if we're
willing to shut down an alternator to save a 2 amp draw,
how can we tolerate the battery contactor with a 1
amp draw? Both loads represent wasted energy that once
dumped into the atmostphere as heat, cannot be tapped to
run a radio.
Anyway it is my understanding that automotive alternators do
not get as many hernias as aircraft alternators and actually
live longer.
First of all . . . there's no such thing as an "aircraft"
alternator . . . at least on the airplanes you and I can
afford to fly. Virtually all the alternators flying on
single engine airplanes are slightly (if at all) modified
version of an automotive design. The problem is that
"aircraft" alternators as we know them are based on designs
certified back in the 60's and 70's. One of my consulting
customers takes brand new Nipon-Dienso alternators and
opens them up to remove built in regulators, machine the
brush holders to allow direct grounding of one brush,
ballances the rotors to VERY tight specs and re-assembles
them with the other brush holder brought out for connection
to an adjustable regulator with ov protection.
In about 7 years of selling these products in a 40 and 60
amp version, fewer than a dozen of over 1000 have been returned
for repairs . . . due to owners washing the grease out of
the bearings while they were cleaning their engines! I've
gathered enough flight test information from flying these
products on experimental ships that getting STC's for
certified installations should be a no-strain task.
In my case alternators may be obsolete by the time I get
to my electrical system, however if I do use a alternator
What else would you use???
I will plan a control switch and automotive type fuses.
No problem >>> EXCEPT <<<< you want to avoid designing
a system where the alternator can be left on after the
battery is off . . . most alternator/regulator combinations
do no run well with a battery off line. This is why I
bring alternator and battery on and off together with
a single switch. Since I use crowbar ov protection,
I use ONE push-pull breaker as the TRIPPED device for
the crowbar ov module. This breaker can then become the
device for shutting down the alternator during maintenance
when you want the ACCessory position on your switches.
My alternator will remain off until after engine start
and be shut down before the engine is stopped.
It'sa no biga deal . . . Since I control with a single
switch, my alternators are ON during cranking . . . and
I don't care when the master is turned off . . . . you
can turn it on and off in flight . . . it shouldn't
be a consideration for sequence during shutdown. There's
a lot of ol' mechanic's tales wandering around out there
looking for good minds to polute. Every time I've
asked a proponent of any particular method to explain
why it's used, the answer invariably is, "that's what
I was taught to do." One never knows who taught the
teacher . . .
Now, go ahead and make your day . . . .
I think you read it wrong . . . to make my day you need to
show ME where I'm wrong. If I propose to be a source for
good information, I'd better be able to stand against the
wall and defend it. If it cannot be defended, it needs to
be removed from the playlist. . . .
I like to turn off my alternator once and awhile (field)
just to see what my battery is putting out (amps) and
to see what voltage it will sustain for a minute or so.
This kind of a test is pretty meaningless because it's
duration is so short. There are two battery considerations.
CAPACITY (ability to run minimum goodies for duration
of fuel on board - 4 hrs is ideal) and INTERNAL IMPEDANCE
(ability to crank engine). These two attributes were pretty
well linked to each other in the good ol' flooded battery
days but the newer RG batteries can be way down in
capacity and still crank an engine.
It's interesting that we overhaul engines when compression
gets too low, replace belts and tires when they are too worn but
we run a battery until it's dead, Dead, DEAD . . .
If you really want a battery to be your most reliable
source of energy, you need to CAPACITY check it. On a nice,
long, day-VFR flight, turn of battery master, close alternate
feed to essential bus and start you watch. Whe battery
voltage drops to 11.0 volts, see how long it ran carrying
just your essential loads (which, by-the-way, should be
less than 4 amps . . 3 is better). If it didn't run for
4 hours . . . then consider replacing the battery.
IMHO a circuit breaker or fusable link is need in the
alternator output lead to protect the rest of your electronics
from the alternator in case of voltage regulation failure.
No breaker or fuse can be depended upon to protect a system
from a runaway alternator. Alternators are by their physical
limits, unable to put out more current than they are rated for.
(Exceptions are when they're really cold where a 60 amp machine
might put out 65-70 amps until it warms up). So, let's assume
the regulator is blown and the alternator is full fielded.
It goes into immediate current limit at what ever it was
designed for which will be LESS THAN the trip value of any breaker
or fuse in it's output lead. Now, all your airplane NEEDS
is perhaps 10 amps out of the 60. Guess where the rest goes?
The battery will try very hard to suck it all in but eventually
it looses the battle and bus voltage climbs. If the battery
is soggy, runaway alternators can product voltages of 50-100
volts on the bus . . . and never trip the b-lead breaker.
This is why GOOD ov protection in the field circuit is
essential.

Couldn't resist this------ I ordered a throttle cable from ASS. It arrived
but was bent at a 45 degree where the flexible cable joins the rigid sheath
just forward from the knob. I called the ASS representative; of course, on
my own dime, can't use the 800 line except for orders. They told me to call
UPS and have them pick it up and return to ASS. I did that. I also asked
ASS to send me a new throttle cable to replace the damaged one.
After about a week I received a new undamaged cable.
To this day I have not received credit for the returned cable. I PAID for
two cables; one damaged cable that I returned and one that was ok. I have
talked to both the telephone people and to Irwin at the Arlington Airfair.
To this day ASS owes me $50 for the damaged cable.
This was only one of the problems that I had with ASS. I'd order 5 items
but instead of shipping them all at once they'd send them one at a time.
It's really irritating to be charged $5.00 shipping on a $4.00 item. I
ordered fuel gauges and senders (can't recall the brand). The gauges
arrived; no senders. I called them. They said the senders were
discontinued, no longer available. What good are gauges without senders???
At least they did take them back. Of course, I had to pay the UPS charges
to send them back.
Am I unhappy with ASS?? You bet your bippy I am. I'd pay twice as much
anywhere else rather than order from ASS. The only good thing they have is
the catalog. Shop locally whenever you can and if you have to order call
Wicks first. Even if it isn't in the catalog maybe they have it anyway.

The Christen system returns to a "T" fitting screwed into one of the oil pan

It seems that when you get to this point (final assy), you're supposed to
intuitively know how to perform an assembly sequence (ie: throw the
instructions away). It seems you've discovered this, and knowing something
about airflow & how things should fit together, want the thing to fit and

Given the .020 controls skin thickness of the -8, and the revised

trailing edge, I have opted to build my controls without the RTV. Van's
folks don't think its needed to prevent cracks. Also, on the elevators it
provides little dams to collect water between the stiffeners at the trailing
edge. In short, I believe that it's unnecessary and can actually encourage
corrosion.

It is my understanding that Van intentionally designed the air inlet with an
increasing cross-sectional area. As the air enters the inlet, the diverging
walls will cause the velocity of the air to go down and the pressure up,
similar to why a NACA scoop works. This results in a high pressure area
around the carb, and an increase in power at altitude. You can almost call
this arrangement a poor man's turbo-charger.

My similar experiences with suppliers led me to adopt this policy:
Whenever possible I pay for goods with my AOPA mastercard. When the
product turns out to be defective and the supplier fails to credit my
account I simply send a letter to the mastercard bank telling them that
the product was defective (or returned, or whatever) and that I'm refusing
to pay. I've won every fight of this sort that has come up. The AOPA
mastercard agreement gives me 60 days to dispute a charge, and it doubles
the manufacturers warranty on most items. That's pretty good protection,
and it's free (assuming I pay the bill right away).
Yeah, it adds a couple of percent to the vendor's cost of doing business.
I've been burnt enough times that I don't care about a 2% hit to the
vendor. I'm interested in protecting myself from the sort of $50 rip off
that ACS inflicted on John.
The only exception I've recently made to my "credit card only" policy was
the pitot tube mounting bracket that I bought from Warren Gretz. I sent
him a check in the mail, and the pitot tube bracket showed up in about 1
week (pretty fast service IMHO).
Oh, by the way, I ordered a pitot tube from ACS two weeks ago. At the
time they told me it was in stock. Today they told me they'd have it in
a couple of weeks. Hmmm, where'd I put the phone number for Wicks....

Ed, From the inlet of the scoop you'll be fiberglassing a tunnel to mate up
with the FAB airbox. The distance between the tunnel you make and the FAB
airbox should be around 1/4". The tunnel length will vary according to carb
location and the diameter of the tube may very well increase over this
length. BTW, I made my inlet on the cowl scoop a little larger than
received from Van's.
When doing the fiberglass work, I'd put some tape over the carb inlet so
you don't get FG dust up your carb.
One suggestion you might consider that will ease lower cowl installation
is to do the rubber seal on the FAB box a little differently. I put the
rubber seal on the top of the FAB airbox (horizontally). For the curved
portion, I attached the rubber seal to the "tunnel" that is part of the
cowl. When you put the lower cowl on, the FAB box nests into the rubber "U"
on the cowl. This beats the dickens out of trying to route flaps of rubber
through a 1/4" crack. Also, I made removable horizontal baffle seals to
help ease cowl installation and removal. Bob Skinner RV-6 BSkinner(at)ltec.net

ebundy2620(at)aol.com
=======================
Ed, The air box opening and scoop sizes are different. Your to fabricate a
diverging tunnel to mate the two shapes together. I think someone posted a
method recently refering to: glueing foam on the scoop and carving/sanding
the foam to match the air box. Then laying fiberglass cloth onto the foam
and blowing up a balloon into the opening to form a smooth finish with
minimal sanding. I guess a condom could be used in place of the balloon if
you feel you need protection....... :^)
ps. don't forget to wrap the airbox with baffle material to form a socket
to seal around the scoop ducting.

equipment backed up. Of course if the whole GPS sattelite network
decides to go down for some reason then you'd be SOL, but that seems
kind of unlikely. As for coverage -- if the FAA is really committed to
obsoleting VORS with GPS, then there will HAVE to be enough satellites,
or the whole system will break down. I imagine that before very many
VORs are decomissioned, they will make sure this issue is worked out.
I am not just thinking hypothetically here, I am trying to plan for an
IFR panel in my RV that won't be obsolete in 10 years, and it seems to
me an IFR GPS with a VFR handheld for backup will make a good, minimum
IFR panel.
This may mean I can't make precision approaches at places where they
still require a localizer/glide slope receiver, but I'm not really all
that anxious to get into situations requiring hard IFR to minimums in my
RV anyhow.

Just order one of everything in the catalog and you'll be fine :-)
Here's my $.02 worth:
WHen you rivet the elevator and rudder skins, You'll need to have
something like the Back Rivet Plate.
I've found the 1/8-inch diameter 3/32 female dimple die to be priceless
when I drilled a hole in a rib too close to the web to get the full-size
dimple die in there.
When dimpling the elevator and rudder ribs down at the trailing edge, a
3/32 vide grip dimpler comes in awfully handy. I've used the pop-rivet
dimpler, but it is a lot harder.
I've used the 3/32 pop-rivet dimpler more times than I can count.
Number 3 Unibit.
Get the 12-inch center-finding rule and save yourself a lot of mental
arithmatic.
AN Bolt guage
A pair of aluminum ships or shears that do not leave a serracted edge. I
use the Andy, but I prefer the Robin, which Avery does not sell.
A box of scotchbrite pads
The "Scotchbrite cutting and polishing wheel kit" is GREAT for deburring
lightning holes.

Subject: | Importane Lycoming Service Bulletin: Fuel Pumps |
As I recall, someone posted some information a few weeks ago about failing
Lycoming fuel pumps. Mandatory Service Bulletin 525 on this issue arrived
today, and I though I should spread the word.
I'll not reproduce the entire SB here, but instead try to summarize it:
SUBJECT: Inspection of High Pressue Fuel Pump P/N LW-15473
MODELS AFFECTED:
(1) New, remanufactured and overhauled fuel injected engines from Textron
Lycoming with P/N LW-15473 fuel pumps shipped between 7/18/95 and 8/14/96,
inclusive. Models included are (L)IO-320, 360, 540; AEIO-320, 360,540;
HIO-360 and O-540-L.
(2) Diaphram fuel pumps P/N LW-15473 purchased between 7/18/95 and 8/14/96
inclusive.
TIME OF COMPLIANCE: Before further flight of the aircraft.
Textron Lycoming has determined that a number of high pressure fuel pumps,
P/N LW-15473, manufactures between June and October of 1995 may have
manufacturing defects that may result in engine stoppage. Several
instances have occured where the retaining washer gasket has become
separated from the pull rod assembly and lodged in the pump outlet valve
restricting fuel flow.
If your Textron Lycoming engine has a P/N LW-15473 high pressure fuel pump
installed, with identification/date code scribed on the pump as 154739506,
154739507, or 154739510, it must be inspected, as follows, before further
flight of your aircraft.
======
I'l stop here, but that gives you enough to figure out if this SB applies
to you. This SB WILL NOT apply to most folks here on the rv-list because
it applies to the fuel-injected engines only.

Hello, Mike, and welcome to the club. Very well said. I was up this
morning at 5:00 and managed to fabricate a couple of rudder stiffeners,
but I'm taking tonight off except for cleaning up the shop and reading

never to work when tired. This project has really got me going.

My trusty Lycoming parts catalog states both the low compression E2A and the
high compression D2A (actually all the B and D series) use the LW-12416
nitrided cylinder and head assembly.
Sounds ok to me to simply replace the pistons.
Your E2D uses a LW-12417 plain cylinder; maybe the plain cylinder was
tapered but somehow I doubt it.

John, You might want to check another source like Lycoming or a larger,
reputable overhaul shop. My information is that this is a matter of
changing pistons. When we overhauled my 150 hp O-320E2A, the cylinders did
have choke in them. Unfortunately, I went back with the 150 hp pistons. I
was thinking of using car gas at the time, which I later elected not to do.

From: | Vanremog(at)aol.com |
Subject: | Crotch Strap Retro-Fit |
A few weeks ago I unwittingly passed on some bogus info to the list from
AM-Safe on the issue of adding the crotch strap to the standard Van's issue
503086-405-2855 harness. Don Grego @ AM-Safe had thought that they had a
buckle tongue that was approximately .250" longer than the standard in order
to accommodate the additional thickness of the crotch strap bracket.
This turns out to be incorrect and Don has confirmed that AM-Safe has no
buckle tongue with the friction bar adjuster that can accommodate the
combined thickness of the shoulder belt and crotch strap brackets. The
longer tongues which are available from AM-Safe do not have the friction bar
adjuster feature and require that the adjustment feature be designed into the
strap (not at the tongue). This feature is designed into the 4000# rated
5-point systems they sell.
For the 1500# rated system that Van's sells, the only option for those of us
adding crotch straps is to modify the existing tongue. This is easily
accomplished and will reduce the strength of the tongue by approximately 25%
(from its rated 4000#).
The following procedure will guide you step-by-step:
1. Remove the tongue side strap from the aircraft.
2. Using a .058" dia drill blank or pin gauge in an arbor press gently drive
the spring pin from the friction adjuster (that knurled bar in the tongue
that the strap snakes around). Just drive the pin far enough that you can
get it beyond the edge of the tongue.
3. Remove the bar, the strap, the clip and the leaf spring (noting their
proper orientations.
4. Clamp the tongue (marked 500535) in a padded vice with the small (mating)
end up.
5. Using a .250" dia round file, reduce the shoulder from the stock 1.325"
dimension to 1.175" (2 places). Maintain the original tongue width (no more)
all the way to the new shoulders, then dress the shoulder areas flat and
round the new corners to match the existing radii.
6. Grind the open ends of the stainless steel clip (marked 500535-401) from
the stock .425" dimension to .350". Round new corners to approximately their
original radii.
7. Complete the assembly in reverse order of disassembly and drive the spring
pin home using an arbor press or channel lock pliers. Done!
You are on your own to engineer the crotch strap anchor point in the seat
area but it needs to be in the rear of the stick cutout area. It really
doesn't have to be that strong as the crotch strap merely reduces the
tendency toward performing the humanoid harness limbo and helps keep the lap
belt low and comfortable on the hips
When donning your new five point harness, install the crotch strap bracket on
the tongue first then the shoulder strap brackets, then buckle. The twisted
geometry of the crotch strap bracket will nest better against the relieved
tongue shoulder than against the shoulder strap bracket.
Any other Qs, E-mail direct.

Subject: | Re: How do I lift an RV6A with engine for wing and landi |
Hello All....
Just my $.02 on this subject - maybe it'll help someone...
The fuselage will probably be on the gear using the wooden "dummy
spar" for a long time while you are getting the fiddley stuff done, -
fairings etc ..etc...and also while you move to the airport for wing
attachment & final assembly. - O.K. - This is what Greg Bordelon and I
did on mine.....
The actual move was "painless" actually... after toying with the Idea
of using extended trailers or similar, we opted to call the local
wrecker company to do the deed. They arrived with the specified big
"flatbed" type of truck,.. you know.., the ones' where the bed slides
off the back, then winches back on. He charged 75.00 for the move
(about 8 miles and 45 minutes T.T.) and it was worth every dime.
Amazingly enough, he said that it was not his first plane move!! The
wings travelled along with us - in their cradle in the bed of a pickup
truck.
As for the big day when it is time to put the wings on - not too tough
really. We used a couple of 2x8 planks about 8 ft long, resting on 4
saw horses. The saw horses should be about the same height or just a
little taller than the bottom of the fuse. Position the first horse
next to and parallel to the fuse and put one end of the plank on it.
The plank is now placed under the firewall bulkhead, and covered with
blankets/ pillows to cushion your vulnerable bottom (oops). Remember,
it is 8" wide so the load is well distributed also. Take a deep
breath, Cinch up your Jockstrap, and lift the other end of the plank -
and up comes your bird - WOW! - wheels up for the first but not last
time - and slip another horse under the second end. The plank will
bend a bit - but don't be alarmed! Repeat using another plank and 2
horses at the tail to get level flight condition (longeron horizontal
at the cabin rail) so that you can align the incidence angle
accurately - as per the manual.
FYI - We found that final wing attach - installing all those the spar
bolts to be a real bitch...( unless of course you are deformed -
double jointed and with strong 5' arms, with 2 elbows per arm would be
about right I think).
Well, mainly Due to excessive beer sampling duties in a previous
existance - my own large, 2X, manly frame simply would not bend to the
alkward angles needed to lovingly, gently, and tenderly beat the
requisite amount of **** out of those bolts. So I somehow got Greg to
do it -- (Thanks again Greg!!). Took about 3 Days and a lot of messing
about with the legs to get final bolt alignment, and many bad words.
(mostly directed at me by Greg).
Anyways up, I went on for longer than I wanted to - but what the hell.
The above worked well for us - and even with the bird painted we
didn't mess up the cosmetics one bit.

Rob Lee

Subject: | Re: Future of Aviation Navigation |
I've been assuming they'd retain the VOR transmitters for those rare cases
where you just happen to have inadequate satellite coverage. You need a
back-up system.
======================================
The system is composed of 24 satellites and 3 spares. In concept they will
bring down the old sats and launch new ones as future technology improves.
The orbits are inclined in 6 planes around the earth. In the air my GPS
almost always locks onto 6 satellites and only rarely has it been 5. The
Russian GLONOSS system is said to be more precise because they do not have
SA(selective availability). SA is the US military requirement to degrade the
signal (i.e., positional accuracy). However, the military has announced
they will turn off SA by 2010. With WAAS (mentioned earlier on this list)
and Deferential GPS, the use of SA becomes irrelevant for general and
commercial aviation. Each satellite has its own atomic clock and each clock
is updated every day. There is already redundancy built into the system. I
don't know the odds but I feel much more secure that a satellite will be
waiting for me 200 miles down the road than when I am tuning in the next VOR
and listening for that dit dit da.
In the future you will most likely see a system that integrates both the
Russian and US systems. Aschroft now sells a expensive GPS that will lock
onto BOTH systems. How do you say "back-up" in Russian?
Ground based nav-aids are old technology, frequently broken, and expensive
to maintain. Just think - there are more than 400 VORs in the US alone and
now 24 satellites are giving you world wide coverage. I was surprised to
hear that a part of Australia lacks occasional coverage. I would like to
learn more about that.

John; First off, I'm not an authority, but I will tell you of my experience
when I and an experienced guy were rebuilding my engine (320 E2D). I had
already had my cly. checked etc, the guy asked do you want to make this a
160 hp? I asked what it entailed and he said different pistons and wrist
pins (piston pins). I asked if the wrist pins were different wouldn't that
mean different connecting rods, he said no, the connecting rods were thicker
walled but the same diameter. There was nothing about redoing the cly, just
ordering different pistons, and since we had not yet ordered the pistons, he
said the price would be the same. Since I'm an old hand at rebuilding cars
to 'original'. I elected to keep my engine 'original'
Hope this helps some.

Don,
I Painted my flaps first, then installed the tape, no problems in 400 hrs. Be
very careful installing the tape it is as sharp as a razor blade, and once it
touches the surface of the flap it's stuck. If you try and peel it off you
ruin it. Get some help with this.

I read a post a while back, I think it was from Bob Skinner, about 3" X .020
UHMW tape, instead of the stainless. It lets the color show thru. I tried it,
and it's holding up just fine. Looks a bit less flashy that the stainless....
Otherwise, prime & paint under the stainless, IMHO.

Put the tape on an unpainted flap. The RV's that I have seen had the top
surface of the tape unpainted. The movement of the flap would surely wear
ugly lines into a painted surface in a short time. Hey, it's stainless
tape, I wouldn't worry about corrosion.

I'm ready to begin riveting my leading edge wing skins. I've heard that back
riveting is a good option. It would seem that you can't back rivet if you put
the leading edge skin in the jig cradle for riveting. I would assume that you
leave the skin attached to the ribs on the main spar when back riveting. Is
this so? Do you usually back rivet the top leading edge skin and remove the
skin and put in the jig cradle to finish riveting the bottom of the leading edge
skin with a bucking bar. My thinking of this process may be a mess. Would
appreciate someone straighting me out.

Elon, The top of the cylinder is a few thousanths less in diameter than the
rest of the bore, I think around 6-8 thousandths. This choke occurs in the
last 2 inches of travel. This area expands in operation because of the heat
generated in this area. If the bore were not "choked", the piston/rings
would slop around at the top of the stroke. This causes wear in the top
compression ring and it's groove. My information source for the above is:
the "Sky Ranch Engineering Manual" by John Schwaner, a book I highly
recommend, by the way. Bob Skinner RV-6 BSkinner(at)ltec.net

Don, I see Mark mentioned the UHMW tape. You might consider this instead
of stainless tape. My roll of stainless is still on the shelf. The tape
Mark is referring to is .010" thick and comes in widths of 1/4" to 5" (up to
17" widths can be ordered) and the roll is 54 feet long. The 3" x 54' roll
is $ 39.15. This will do a lot of flaps. I also put a 3/4" strip of this
under the wing skin where it contacts the flap. Whether you use stainless
or the UHMW on your flaps, they will eventually scratch unless you were to
wipe the flap and bottom of the wing skin each time before you retract your
flaps which is pretty impractical. Scratches in the UHMW aren't very
noticable whereas they are very noticable with the stainless steel tape.
BTW, I installed the tape on the flap after it's final coat of paint and
after 300 hours, it's still stuck good. The adhesive on this tape is really
sticky.
I've found a lot of other uses for the UHMW tape. It can be used anywhere
things rub together. Landing gear fairings and top and bottom cuffs, wing
root fairings, on the tip-up canopy side skins where they over lap the
fuselage. I'd guess this material would work well on the aft deck of the
RV-4 where the canopy rubs the fuselage. I've used it on the engine mount
where there is a possibility of something rubbing the paint off the mount.
I used a couple of small pieces on my six where the rudder cables exit the
fuselage. It's handy for stuff around the house, too. I put some on my
Nordic Track skis when the little "bumpers" wore off. That was two or three
years ago and it hasn't worn through yet.
For anyone interested, the name of the company is United Plastics Corp.
and they can be reached at 1-800-537-9724. Get their catalog, they've got a
lot of other interesting stuff in there, too. Bob Skinner RV-6

The cables that I ordered are considered "special order" by ACS and were
quoted with a one week lead time, not a month. They still haven't been
manufactured yet!!! The three cables will have a threaded steel sleeve
swaged on the casing where it penetrates the firewall.
The following cables were ordered for my RV-6A with an O-320 D1A engine and
Woodward governor. They will be installed horizontally under the instrument
panel. I will not be using the vertical arrangement as specified in the plans.
Throttle cable:
A-800 Black friction lock control (ACS#05-08648), 48" long with a threaded
steel sleeve located 24.0" behind the panel nut. The cable will penetrate
the firewall through the slanted surface of the governor box, on the right side.
Mixture cable:
A-750 Red Vernier control (ACS#05-07848), 48" long with a threaded steel
sleeve located 24.5" behind the panel nut. The cable will parallel the
throttle cable.
Prop Cable:
A-750 Blue Vernier control (ACS#05-07960), 60" long with a threaded steel
sleeve located 32.5" behind the panel nut. The cable will penetrate the top
left side of the firewall.
The controls are still on order, so I haven't actually installed the cables
with the above dimensions yet. If a dimension is in error, I will post it
to the list.
ACS quotes a price of $6 for the threaded steel sleeve. The cables were
ordered along with many other items. They billed me for the shipping on the
in-stock items that were shipped. I was billed an additional $15 for
shipping of the cables. This policy was NEVER explained either in their
catalog or when the order was placed. The $6 sleeves wound up costing $11
each when the additional shipping is added. The $15 shipping charge that
was billed to my credit card is in excess of the rates published in their
catalog. For the shipping to be $15, the cables would have to weight a
total of 27 pounds!!!!!! IMHO, this borders on credit fraud. They have
already charged my credit card, the bill has arrive from Mastercard and I
have to pay for them or face finance charges, even though THEY HAVEN'T BEEN
MADE YET.
Wicks has the same cables, without the sleeves, in-stock with the exception
of the throttle cable, which is on back order. If ACS had been up front
with me from the start, I would have ordered stock cables and put a grommet
with shield at the firewall penetration. If I had known then what I know
now, the stock cables would have been ordered from Wicks. Hopefully others
on this list will keep this in mind when ordering their MTP cables. ACS
isn't the only supplier out there.

Couldn't pass this up . . . . in my experience, too many builders
put off consideration of electrical system issues until the airplane
is about done and they're ready to start stringing wires. I'd encourage
every builder to start gathering information early . . . the range
of options is tremendous. I'd like to believe that when the time comes
to start stringing wires and drilling holes in the panel, you've had
it all planned out for some time.
Whether the 'Connection is involved in your project or not, try to
develop an awareness and appreciation for things that are hidden
by sheet metal, paint and upholstery. If you see an airplane done
by a real craftsman, ask if they documented their electrical system
and the materials used. Quite often they're willing to share it.
You're not necessarily looking for a system to clone . . . but you'll
be surprised how easy it is to make decisions about your own airplane
after you've researched a dozen others.
If you're an AutoCAD user, I have uploaded a wire book "seedling"
disk to the maintenance library of AVSIG on Compuserve. The same
data will be downloadable from our website in a few days . . . I'll
post a notice when it goes up. This disk contains a wire book in process
for a client's airplane. It has the forms, symbols library and lots
of systems pages already drawn . . it can save you HOURS of work.
Search on "nuckolls".

Ron, The main skins, not the leading edge & fuel tank are what is back
riveted. I've never heard of anyone trying to backrivet the LE. However,
it sure would be neat if someone would try it and report back to us:) I
speculated on the list some time ago about doing this and when I get to that
point on my wing construction, I'll check it out for myself. I thought it
might be possible to leave the LE clecoed to the front spar and all of the
ribs and, starting at the bottom of the ribs, start back riveting and work
toward the nose as far as you can go. The idea didn't seem to generate much
discussion on the list and it may not be worht the risk to a lot of builders.
They do make a right angle rivet gun, which is quite expensive. Also,
there is a very short barreled, straight rivet gun that uses a special,
short rivet set that looks as though it might fit inside the LE and tank
while it is off the airplane and in the craddle. It's priced at $ 320.00
from U.S. Industrial Tool & Supply.
On the main skins, back riveting seems to work very well. I didn't do
this on my first RV but bought the back riveting stuff for my second. I
helped a RV-6 builder in CO back rivet his wings and it worked out well and
I sure intend to do my main skins on my second RV. There are also a lot of
places on the fuselage that back riveting will work. Bob Skinner RV-6

The report from this accident was written up by the NTSB who stated

By the way, there is a large list of these reports linked to the NTSB web

I just back rivited the top main skins and not the leading edge skins.
I just put them in the cradle, reached inside with a small bucking bar
and rivited from the outside. It helps if you have long arms near the
front radius or a friend to hold the bucking bar in these areas.

Elon,
I should have posted to the whole list, I provided some info on this to
someone else.
The GPS satellite system is biased towards the continental U.S. and the
Northern hemisphere. As you built the system we cannot really complain. For
this reason the orbital planes are established to provide optimum coverage
for the U.S and Northern hemisphere. There are occasional periods in the
southern hemisphere when there are insufficient satellites in view for a GPS
to maintain its RAIM function. This does not effect GPS as an aid to VFR
navigation but does effect its licensing in Australia for sole IFR use.
There is much discussion by our local aviation authority as to means of
providing sufficient systems integrity to enable GPS to be used as a sole
IFR aid for en-route navigation and non-precision and precision approaches.
For us even one satellite is a big ask although one geo stationary satellite
over Australia would provide the requisite wide area augmentation.

Was reading thru AC43.13 last night, it has this to say on trim tab
free play (Chapter 2 Section 1 para 55e)
The total free play at the tab trailing edge should be less
than the following. If the tab span does not exceed 35%
of the span of the supporting control surface, the total free play
shall not exceed 2% of the distance from the tab hing line to
the trailing edge of the tab perpendicular to the tab hinge line.
If the tab span equals or exceeds 35% of the span of the supporting
surface, the total free play is not to exceed 1% of the distance from
the tab hinge line to the trailing edge of the tab ...
So, if I read this right, going by my plans, the free play should be
less than 0.11" or slightly under 1/8"

I would have posted this to you privately, but you gave no email
address, (I dont post generally to the list anymore, too many snobs
ready to "sharp-shoot" what you're doing and your motives . ). but I thought it might be important enough to break this
rule to advise you to check your jug hold down nut torque. It may be
that the cracks in the pipe are due to the jug moving about on it's
mount. I understand Lycs are noted for this. Just a thought.... (I'm
certainly no expert, nor am trying to sell you anything).

Subject: | Cylinder Choke...Explanation |
For Elon...and others....
>From Light Plane Maintenance's Book, TOP END, Chapter 2:
"...In aircraft, choke is the difference between normal TBO and a premature
top overhaul.
In an aircraft-engine cylinder, when the crankcase end points up, the
clyinder wall taper toward the "head" end of the barrel. This taper is the
cylinder"s "choke".
Why taper a barrel this way? In an air-cooled engine, a fairly extreme
temperature gradient exists from the base of the cylinder to the head during
normal operation. Thus, if the cylinder barrel did not incorporate a slight
taper when cold, it would assume a negative taper or "tulip out" when hot
due to thermal expansion at the combustion end. This, in turn, woiuld lead
to irregular, rapid ring wear, poor oil control, and loss of combustion
efficiency. This why a new Lycoming and Continental cylinders leave the
factory with as much as .010-inch taper at the head end of the barrel.
It doesn't take much choke to do the job......... Lycoming's direct drive
Table of limits doesn't contain new-limits choke specs, but does set a
service limit of .0045-in (for-and-a-half thou) on old barrels. ......"
My old 1969 Lycoming 320 in my Cessna 172 has about 5900 hours since new,
has been overhauled twice, has 1900 hours since last overhaul, and on my
trip to from So. Cal to Alaska and back this summer, used 5 qts of oil in 55
tach hours (11 hours/qt). Whoever last overhauled it....got the choke right!

Subject: | Main skin overlap. |
A few weeks ago I looked over an RV6A that was an excellent example of
workmanship.
I noticed that the builder had used a unique approach where the inboard &
outboard
top skins overlap. I wonder how unique this is.
The technique: Where the top main skins overlap, the outboard is on top of the
inboard skin.
This causes a small uneven area, due to the thickness of the metal. This
builder trimmed
back the area that was sitting over the spars from the inboard skin. This let
the the outboard
skin lay flat against the spar over the inboard skin, the un-trimmed part.
Now before I confuse you more, there is a double set of rivets in the area where
the skins meet.
One row runs down a rib the other just goes through the two skins. He did not
trim this area,
just the area over the main spar and rear spar. This allowed the skin to lay
flatter and
be less notable.
Here is a cryptic diagram in an attempt to clarify the above description.
-------------| main spar |-----------------------
-----| |. . Z
Inboard . .| |. . Outboard Z
Top . .| |. . Top Z
Main . .| |. . Main Z
Skin . .| |. . Skin Z
. .| |. . Z
. .| |. . Z
. .| |. . Z
-----| |. . Z
-------------| rear spar |-----------------------
^
|- Inboard and outboard skins meet here.
Now if you slide these together, with the outboard over the inboard skin you
will see what I mean.
He did not do this to the bottom skins, no one pays them any attention anyway.
Even with a relief cut/hole in the corners of the cut out areas, it looks like
a good place
for a crack to start. IMHO
Just how unique is this? Have any of you seen or done this to your skins?

I've heard that the pegging of the "G" meter may not be all that
significant. The centrifugal force imparted to the fuselage when the
wing seperated could have easily caused the meter to peg and freeze. I
think that the ultimate conclusion is correct, overstress of the wing,
but not that all the "evidence" is conclusive.

Louise, Deju vu for me! It took 4 or 5 times welding in different places
before those d### exhaust pipes didn't crack anymore. The final fix for me
(800+hrs,no cracks) were two braces from eng to pipes and a crossover brace
pipe to pipe just to the rear of where the eng to pipes braces would be.
The vetterman pipes have some good press but I have no personal knowledge.
Good luck!

Hmmm. Geostationary satellites are over the equator, and up at roughly
27000 miles. What orbital height are the rest of the satellites at? I
wonder how that would effect accuracy.

Louise, This is common on the Allan Tolle exhaust system. I had bought a
Tolle system but after hearing of all of the problems, sold it at a loss and
bought a Vetterman 4 pipe system made of mild steel. I just didn't want to
take a risk of catching something on fire with the Tolle system. I bought
the four pipe mild steel as it was the cheapest and I figured I'd already
tied up enough money in exhaust systes.
The homebuilt bulletin board in K.C. is full of problems with the Tolle
system. Alan is a nice guy but his systems stink. Some of the fixes tried
include gussets, slip joints and saddle links (like Vetterman uses). Also,
the interior of the tube must be flooded with argon. (This is a tidbit stuck
in the cobwebs of my mind, don't remember who told this to me.) The main
problem area of the Tolle system in on cylinder #4.
I now have the Vetterman stainless steel crossover. The reason for the
change from 4 pipe to crossover was to obtain more cabin heat. So far, I've
not heard any complaints about the Vetterman system.
By the way, I still have the Vetterman 4 pipe and will sell it for $ 150.00.

A box of scotchbrite pads
Don't buy scotchbrite pads from tool or paint suppliers.
You can use the regular green dishwashing ones from your local
supermarket... heaps cheaper.
I originally bought one each of the red and grey (coarse and fine) pads,
but have only occasionally used the coarse one, and never used the fine one
I buy my scotchbrite pads from local industrial tool suppliers.
I buy only the red ones and scuff the whole plane with these prior to
painting. They are not very coarse, ie. no deep scratches (the green ones
just piss me off). Additionally, I purchase them by the box or
case.....what ever it's call. After using them for a while you will be able
to tell when the one your using is worn and needs replacing.

James this is standard practice on the top two piece wing skins, just
round the corners where the cut outs are and there will not be a
cracking problem.

When attaching stainless steel tape to Flap leading edge should the flap

Also is is best to leave top surface unpainted or has anyone painted it

Don Pfeiffer RV6

=========================
Don,
On my friends (Rob Lee) plane we painted the top side. The steel tape is in
place and seems to work fine once you get it on right. "Check Six Mark" has
a supplier of a semi-clear plastic tape that looks real nice.
I'm planning to us the semi-clear tape on my plane but I don't understand
why we can't apply the tape to the underside of the top wing skin. I think
this would work just as well and it would be out of site.
Any comments?

Subject: | Oil Separator Return Line/Ugly Goop |
Why would you want to return that ugly goop to the crankcase?
Some builders have been collecting the oil return in a f-wall mounted
container and periodically draining it. This will keep the stuff off
the belly of the plane. The cowls come off at oil changes. Does
anybody have a feel for what volume is required (25 hour intervals).
David Fried
dfried(at)dehavilland.ca
=====================
David,
The volume of oil in the seperator is unique for each engine. Engine
blow-by is a good indicator of the overall health of the top-end. This is a
case where less is best. Every engine will have some blow-by. What is
normal volume? I don't know and it depends on how much money you want to
spend in the top-end. Most a/c I've seen seem to have a one to two pint can
mounted to the firewall.
Maybe other listers can inform us concerning how much oil they are
trapping. For example: my Cessna used to have a oil slick on the belly
continuously, I replaced the pistons/rings and cylinders and now I have a
clean belly.......a/c belly that is .

G meter readings in an aircraft that has hit the ground after an in flight
break up mean little to me. What do you think the G meter did when it hit
the ground?
Unless something pinned the meter in flight as the aircraft broke up it's
readout could be altered when the wreckage impacted the ground and thus
rendering the data useless.
I would think more reliable information can be obtained by the observations
of those that saw the incident. The deails in the NTSB accident synopsis
were "The pilot of the RV-3 initiated a steeply banked right turn, after
following another aircraft in a rapid climbing maneuver. During this turn,
which was described by witnesses on the ground as extremely tight, the right
wing was seen to separate from the fuselage."
So who knows what the G load really was. Unfortunately it took this accident
to uncover the potential problems with the 3 wing. Van has taken the
necessary steps to insure the 3's are modified to withstand his original
design limits.
The wing is different from the 4 & 6 wing and those have been tested.

You're right Vettermen is the only way to go if you can't build your

When an aircraft hits something as hard as the ground it will usually
stop or leave an imprint of where the needle on the gauge was at time

Geostationary sats in the Clarke belt are 22,300 miles. GPS sats orbit at
one half that at 11,000 miles. There are of course numerous low orbit spy

Subject: | canopy frame details |
Okay, guys and gals, a question I need answered ASAP, if you please:
I'm at the point of cutting the plexi for my 6A tip-up canopy (gasp, tremble,
swallow hard). Before I do, I want to get (at least) one thing straight.
The canopy must transition from sitting atop (outside, if you will) the fwd
canopy skin to a position inside(below) this same skin as it wraps around the
sides of the canopy frame. (i.e., the plexi must cross the plane of the
aluminum skin at some point in order to fit in the groove on the side pieces
of the frame, since the aluminum skin becomes the outside of that groove at
the sides, yet sits below and inside the plexi up front over the instrument
panel). Is that clear as mud?? Those of you who have completed this phase
will know what I mean.
As I see it, one of 3 things must happen: the skin must be notched or the
canopy must be notched where the two pcs cross over, or the skin must be
dog-eared inward at the corner to lie flush with the canopy frame side pcs
and let the plexi pass over at that spot. Any of the above would then need
to be concealed with the figerglass fairing strip. My detasiled study of the
latest update of the manual and plans has shed no light on this geometry.
The photos are of the prototype parts which only vaguely resemble the parts
before me. Vintage Van's documentation, for sure. Boy, if they had *me* to
do their manuals, I'd make sure they were thorough and we could *all*
understand everything . Well, they haven't offered me the job, so that's
everyone's loss, and Frank Justice will just have to fill in for me :-)
Any suggestions on how to fit the canopy and skin happily together would be
appreciated. I hope to forge ahead with the Norton wheel tonight!

Jerry, Unfortunately, I also put my freshly re-pitched prop back on the
airplane at the same time that I switched exhaust systems. There was a
minor performance increase, however, I would give credit to the prop change
for this change. My gut feeling is that the exhaust system change didn't
accomplish much (except give my wife some much needed heat in the cabin) and
I believe that Larry Vetterman thinks the same thing, if I remember the
conversation I had with Larry, correctly. Boy, that Vetterman SS cross-over
is a thing of beauty, isn't it?

I would have to say that the G meter being stuck at 9.2 g's would have to
mean that a 9.2g force from either acceleration or deceleration would have
to be exerted on the meter until the meter was catastrophically impacted in
such a way that the device locked in that exact indicated position. IMHO I
would have to say that a 9.2g force created from a control input would not
"lock" the meter in that precise position. In addition, I don't believe that
the forces generated by a nasty in-flight break-up would lock this guy in
position either. I would say that the forces required for such a thing to
happen would be much more likely to occur from the rapid deceleration of the
device as it impacted the ground or another object of large mass. Now if a
person were doing a hard pull-up into a cliff or something obvious like that
it might be plausible. Sounded good though.

Bill; The dog eared inward is the way I went. The plex. is on top until
that point, which is at the rear edge of the forward skin, and really, it
stays on top (the outside until covered with the side skin) back behind
there. The front skin I bent inwards to fit as close as possible to the
canopy side frame that has the indentation along the top. The plex. fits in
the indentation and then the side skin fits over that. It was a little
tricky getting that blend there, but without the fiberglass fairing, which I
did not use, it worked out fine in the end.
The reason I did not use Vans fiber. fairing, They told me at the time it
was as difficult fairing it in as it was to just start my own fiber.glass
filling.
If I didn't make it clear, let me know.

Subject: | Back Riveting -Wing Skins |
I back rivetted the top surface of the leading edge of my left wing and it
turned out great - much better than my right wing that I did in the
traditional cradle method. I clecoed the top leading edge to the spar to be
sure everything was properly aligned, and then removed the clecos from the
bottom surface so that I could lift it up to back rivet. After the top was
back rivetted, I clecoed the bottom surface back on, removed the leading edge
from the spar and finished the rivetting job in the cradle. I used the extra
long back riveting set and dumb-bell bucking bar obtained from Bob Avery. I
started at the bottom and worked up, rivetting in the same basic sequence as
I drilled. The last couple of rivets near the leading edge were a little
touchy, but it worked ok. I recall that I left the forward most cleco on the
bottom side in place as long as I could to help keep the top skin tight to
the ribs. Bucking the bottom of the inboard rib was also a little tight, but
my hands were small enough to get it done. Would I do it this way again?
You bet, the result is worth it.

Ron, The main skins, not the leading edge & fuel tank are what is back
riveted. I've never heard of anyone trying to backrivet the LE. However,
it sure would be neat if someone would try it and report back to us:) I
speculated on the list some time ago about doing this and when I get to that
point on my wing construction, I'll check it out for myself. I thought it
might be possible to leave the LE clecoed to the front spar and all of the
ribs and, starting at the bottom of the ribs, start back riveting and work
toward the nose as far as you can go. The idea didn't seem to generate much
discussion on the list and it may not be worht the risk to a lot of builders.
They do make a right angle rivet gun, which is quite expensive. Also,
there is a very short barreled, straight rivet gun that uses a special,
short rivet set that looks as though it might fit inside the LE and tank
while it is off the airplane and in the craddle. It's priced at $ 320.00
from U.S. Industrial Tool & Supply.
On the main skins, back riveting seems to work very well. I didn't do
this on my first RV but bought the back riveting stuff for my second. I
helped a RV-6 builder in CO back rivet his wings and it worked out well and
I sure intend to do my main skins on my second RV. There are also a lot of
places on the fuselage that back riveting will work. Bob Skinner RV-6

If you have used a G-Meter then you understand that they have three
needles one for +G one for -G and one that locks at either the highest
positive or lowest negative G reached during a maneuver.

You're right, Cheryl. You might not need it and it would be easy enough to
add later. You could always try just dumping the "air" on to an exhaust pipe
and see how you get along. I put an oil/air separator on my six and the
bottom of the fuse stays pretty clean. My separator came from a salvage
yard and was out of a Cessna. Don't forget to put a "breather hole" in the
crankcase line to prevent pressure build up in case the outlet freezes (not
likely IMO, but considered a good practice).

Hmmm. Geostationary satellites are over the equator, and up at roughly
27000 miles. What orbital height are the rest of the satellites at? I
wonder how that would effect accuracy.
Keith S. Barr
=====================================
GPS satellites have a 12 hour orbit. Not knowing orbital mechanics - or even
a good A&P, I won't assume that they are at 1/2 the altitude of geo-sync (a
24 hour orbit). However, they are a heck of a lot lower. And that's the
problem with geo-sync. Because of the great distance the signal strength is
abysmal. Besides, the most populace part of Australia is 30-45 deg from the
equator. Not good geometry.
Maybe the United Nations should coordinate a Civilian GPS system funded by
all of the users of the world. (note, I said "users"). The horrendously
costly learning curve has already been paid for by the military so
commercial start-up costs should be much cheaper. Let the military have
their own system. Problem is you know many countries will be fearful of
security (you heard the scenario...an auto pilot, GPS guided C-172 homing in

Yes --three needles --BUT
One needle shows current g loading.
Another locks in the highest positive g reading, and
Another locks in the highest negative g reading
The last two can be reset to the 1g reading by pressing a button.

The skirt overlap (at the longerons) on the -6 slider is something I'd like

think Allen Tolle is still making his systems, but there are quite a few of
them out there since he was the only source of RV exhausts for a quite a few
years. Maybe Santa will stuff a Vetterman down my chimney.

There are three needles on my g meter too and I think you may have missed
the point. Final indication of the meter is either when the last force is
imposed on the meter (impact with mother earth) or, if the manuever
indication is to be believed, the g meter would have to be catostrophically
locked in place where it could not respond to the impact with the ground.

Subject: | 150 hp to 160 hp upgrade |
There are two things to consider when modifying the **-320 series engines. I
paid $7,840.00 to learn this. My engine was tagged IO320B1A, and I was
assured it was. I put 430 hrs on it, on top of 568 sfreman. It started to
foul plugs badly on 1 and 3 cyl.s, so I pulled them to have them checked out.
By the time the engine was back on the plane, it would suffice to say the
"case" was the only thing that was good. IMHO, put out the cash for a new
engine; the chances are real good you will end up like me and a lot of others
with an equal amount of money in a "bargain" engine. I bought my engine 6
years ago for $5300.00, spent $7840.00 for a MOH this year, and new engines
from Van were $14,000.00 at the time.
1) The cylinders for the 160 are tapered. I highly recommend using these
cyl.'s when doing a 160 hp. engine. Even in new, tight conditions, I am
getting more power than I ever did with the straight cyl.s that were in my
engine (which were supposed to be tapered).
2) If you are doing this to an -E series engine,such as an 0320E2D, bear in
mind that the front main bearings are the same as the 0-290 engine and are
not as strong as the factory 160 hp. engines. The people that did my
overhaul, Premier Aircraft Engines in Troutdale, OR ( who are engine gods in
my view), and also an author that I forget, do not recommend using 160 hp
pistons on these engines because of the higher pressures. And if you are
going with a CS prop, there is even more reason.
I'm not on the list, so if you have any Q., email to me.

I don't think Larry would fit:) I was pretty miffed after I had bought my
Tolle system and found out that several "in the know RV people" knew of the
big shortcomings of this system and yet, nothing was said. The true facts
were not widely known and this resulted in the installation of a pretty darn
un-airworthy exhaust system on a lot of airplanes. I considered it a
dangerous system. Hot exhaust gases blowing on anything in the engine
compartment is not a good thing. The final straw came for me at S&F when a
RV-4 pilot from California taxied back in after the system let go during run
up. I was around his airplane as he was removing the system and he was not
a happy camper. From the bits of conversation I picked up he'd known of the
problems with this system and had yet to change over to something airworthy.
I sold the brand new Tolle system at a pretty good loss, but it was a good
trade as far as I was concerned when you consider the alternative. (And
yes, the purchaser was very much aware of the short comings of this system
but it was priced right and he figured he could re-work the system and have
something acceptable. I was so mad, I never wanted to see it again, even if
it could have been made to work.)

Bob:
I have an Alen Tolle system That crackes Twice in the first 20 Hr
also. I had a top Knotch welder look at it and "fix" it so it wouldn't
break again. He put in wedges off the #4 cylinder flange and rewelded
the whole thing with argon gas inside the pipes. (He said that most of
the problems were due to the poor welding job.) That, coupled with the
proper bracing to the engine to control vibration, and I haven't had any
more problems in almost 800 Hr of use.

Subject: | RV-6 tip-up canopy cutting |
Looking back, I guess I was doomed before I picked up the cutoff wheel. I
never knew what hit me til it was all over...
I was going to be oh, so careful, too. Measure three times and cut once, as
they say. But now I can write a sequel to Ken's "Traps in Cowl Land."
If you haven't begun the successive-trimming butchering of YOUR canopy yet,
let me warn you. Don't make the assumption I did. The beautifully-molded
compound curve in the front of the canopy is the scrap; the simple curve in
the rear is the part you want to save, and measure your initial trim
distances from. Don't ask why, it just is. Maybe they did it to torment
you. I can attest to one thing: if the canopy blank is carefully trimmed
along the front mold line and then measured back the suggested distance, it
will indeed look like a good fit in the making. You cannot tell much at this
point, since the canopy must sit atop the fwd fuselage skin in the rear, but
ultimately must be trimmed to fit beneath it. Because if the varying top
curvature, the canopy will not lay properly atop the rollover structure
without much of the front plexi trimmed away (takes forever in small passes)
and by the time you do that (or at least by the time I did that)- voila! the
rear of the plexi has moved forward as well as upward as the front is nibbled
away. Very anguishing to watch this happen and be helpless to stop it. Now
your canopy is lined up (no more vertical gap in the back) but the aft edge
is sitting 3" in front of the fwd fuselage (turtledeck) skin!!! A permanently
open sun roof! How neat! Know what time it is now? Time for a new skin,
one you can trim to match the remaining plexi and fashion your new, much
smaller rear window!
Fear not; Airparts will sell you a suitable 48x72 piece for around 50 bucks,
and not only will the service be faster than Van's but the crating charge
will not double the cost of the order! Next week I learn to drill off a skin
and use it as a template for a new one. The missing plexi I need is in the
scrap pile, gone on the initial trimming, and in retrospect looks like it
would have fit the turtledeck very well indeed. :-(
Why not leave the rear a bit long at first? It will hit the baggage bulkhead
in the rear unless trimmed before first fitting; the mistake I made was to
assume the front mold flange was the initial starting point. If I had it to
do over again, I would trim the rear flange conservatively and make the first
big chop in the front, in that beautiful sensuous compound curve that your
instincts tell you is to be conserved at all costs- WRONG! Done properly,
you will end up cutting much more of the front away than the rear. At least
I think this is so. I haven't done a canopy properly yet, so I'm
speculating.
So, next time I want to lighten the aeroplane and shift the c.g. forward, I
think I'll leave off an elevator, instead. ;-)
Thanks to all who responded to my earlier canopy querry, but now I've got
bigger concerns.
Regards, all.

Bill, Before dirlling your skin off, it might be worth a call to Van's or
their canopy manufacturer to see if they: 1. Have a damaged canopy from
which the rear part could be slavaged or 2. Have them lay up a rear portion
on their mold. This is assuming that the old mold is still around as I'm
certain that the newer canopies are "free blown" and not molded. Whatever,
maybe a couple of phone calls can save you a little work and allow you to
"shed a little light" into your baggage compartment.

Subject: | Re: Exhaust failure #4 cyl.on 0-320D1A-Tolle design |
I have a couple of ideas about the failing exhaust systems that I would like
to share.
It sounds like what is happening is high cycle fatigue if the pipe(s) and
the point of failure is the pivot point of the moving mass. A couple of
things to keep in mind for a problem like this: The natural frequency of the
pipe(s) is probably in the same range as the frequency of the exciting
force(eg. engine, prop and other moving objects)or it could be a 2nd, 3rd,
4th, and so on, order harmonic of the exciting force. This will account for
why there are varying failure times in relation to the same design on a
different airplane, as there are differences in the rpm and engine types and
prop types. This means there are a couple of ways to stop this problem as
follows. 1) change the mass of the pipe(s) to change it's natural frequency.
2) determine the frequency range and node locations (if harmonics are
involved) and brace at the node(s) to reduce the effects of the vibration by
dampening and stifening. 3) determine at what rpm the damaging frequency
occurs and avoid prolonged running at that setting thereby avoiding exciting
the pipe(s).
If you want to know what the natural frequency of your exhaust sytem really
is it's a matter of placing an accelerometer on the system with the engine
off and taking a small deadblow hammer and rapping the pipe. A peak will
occur indicating the natural frequency. With that information in hand one
can simply do the math to learn about what frequencies could be exciting the
system. It's not really as difficult as it sounds and really the people who
manufacture these systems should study there design in this way and design
for success BEFORE they ever sell the first system. groberts(at)telcomplus.com

that includes seven pictures and a complete description of how I was able to
fit my slider canopy by myself without any help except to put the canopy on
the frame a couple of times. It turned out to be one of the easiest parts of
the project because I came up with a better way to do it. I did not follow
the directions!!! The canopy fits perfectly with no gaps anywhere. It was a
piece of cake. There is also an article with two pictures and a sketch of a
complete rudder trim system that will keep your cables taut and provide for
rudder trim at all speeds, plus lots of other good tips, hints, tools, etc.

Hi all:
Sam James sells a much higher quality set of pants- the one set of Klaus's I
saw were worse the the Van's two pc, and those are BAD. Could be the set I
saw slipped thru QC, but...
Tom Whelan (Bounty Hunter RV-4), Dave Anders (230+ mph RV-4) and others are
using Sam's pants on their birds. Unfortunately, I already had a different
style (Nemisis copies) on my bird when I found out about these.
2 pc pants, $150 plus shipping from FL
James Aircraft
941-675-4493
Ask for a brochure with pics of his root fairings, too. These are fiberglass
compound curve things that slip onto the -4 or the -6, eliminating all that
fussing with the other two styles supplied by the factory.
Check six!

Hi Tim. Stands for "ultra high molecular weight", usually used with

Subject: | Report of incident |
I would like to report two items to the list. I have RV-4 kit #3933
which was first flown in April 96 and currently has 85 hrs.
1 - At about 60 hours I had the cowl off doing some minor maintaince. I
happened to notice two bends in the firewall, about one inch above the
lower engine mount attach points, both on the corners of the firewall,
the 90 degree bend in this area is for the rudder peddles to move freely.
A friend and I inspected the motor mount, rivets, weldments inside,
longerons and could find nothing unusual. I called Van and talked to Tom
Green about it. He indicated that this has been reported before on
RV-4's with the longer gear legs and that he feels it is some sort of
stress relief which is taking place and that the area should be
re-inspected during annual. I had the cowl off at 85 hours adding break
fluid to the reservoir (sp?)(see below) and the area seems to be the same.
I don't believe this was apparent during my 50 hour inspection as I
changed the oil at that time and believe I would have noticed it. I don't
remember any landing hard enough to be suspecious. I will continue to
monitor the areas every time I have the cowl off.
2 - Just after landing 9/15/96 my left break peddle "went to the floor".
I was able to safely taxi to the ramp and pulled the wheel pant. Break
fluid was dripping on the left wheel. Upon inspection I discovered the AN
fitting that attaches the AL break line to the 90deg elbow was finger
loose. After re-tightening it the breaks functioned normally. When I got
back home I checked the reservoir and found it to be about 3/4 low on
fluid, I filled it back up, checked #1 above, replaced the cowl, pulled
the other wheel pant and checked the other break (it was ok but I could
tighten the fitting about 1/8 turn) and declared the A/C airworthy for
the Roswell fly-in next weekend!
If anyone has any comments on either incident (good or bad) I will
certainly welcome them.

A couple of things here, and maybe we can lay this issue to rest...
I've been an accident investigator on two Air Force A-10 accidents. In
each case, we were able to ascertain the G forces PRIOR to impact by
obtaining "capture marks" on the G meters. As Jerry Springer explained,
the needle makes a small but definite mark on the guage on impact with the
ground. In the case of the G meter, we could tell the maximum positive and
negative Gs the pilots had pulled by those marks. Mr. Roberts is incorrect
in his statement that ground impact will cause the final readings on the G
meter. The impact marks on the G meter will show the current G as the
aircraft hits the ground. The needle is "captured" before it can actually
move to show impact forces. An aircraft hitting the ground in a situation
as described in the RV-3 accident would most likely impact with more than
9.2 Gs, more likely 30-40 Gs. Bottom line: you don't look at the
needles...you look at the marks the needles left in the face of the guage.
Another issue. In the A-10 and most, if not all, jet fighters, we have two
positive G limits: symmetrical and asymmetrical Gs. Our symmetrical limit
is 7.33 positive Gs; asymmetrical limit is 5.0 Gs. A symmetrical G is one
where the acceleration is essentially through the top of the aircraft,
either straight and level or in a steady-state turn. An asymmetrical G is
one where the aircraft is rolling; not necessarily turning, but in the act
of rolling. (You aero engineers can probably explain this better.) In the
RV-3 situation, where the pilot was in a hard left roll, the right wing was
no doubt pulling more Gs than the left. The pilot may not have felt like
he was over-pulling, but the aircraft sure felt it!
It's interesting we don't hear about symmetrical and asymmetrical Gs in the
civilian world (at least I haven't). IMHO, it's important to consider that,
while rolling, the G meter might say "9 Gs" but the outside wing is
pulling 11 or more.
Let's be careful out there!

Dan, my hangar mate has an RV-4 (standard gear legs) and the same thing
happened on his firewall. The aircraft is well built and there have been no
"hard" landings. He noticed his firewall problem at about 10 - 15 hours. He
now has over 300 hours on his aircraft and the bends have not changed at all.
I have not seen this on the other 2 RV-4 in my hangar or any other RV that
I've looked at. It seems to be a cosmetic problem (after the stress is
releived from the firewall that is).

Good point! As our G-meters tend to be in the center of our aircraft they
are only showing us the AVERAGE force of gravity be exerted on the aircraft.
Personally, I get uncomfortable pulling more than 4.0 to 4.5 G's. Does
anybody pull more than this on a regular basis? If so, what the heck are you
doing? (I really do want to know).

My dad always told me that the purchase of new tools was the reward for

find a project to justify its purchase. Seems logical to me ;-)

Fellow RVers,
Although I only live 110 miles from York, NE, home of Craig Bairs award
winning RV-6, until the Sat. Fly-in at Harvard, NE I had never seen the
plane. We missed each other by one day at S&F. His six was awarded best
low wing at S&F this year and is featured in the Sept. issue of SA. It's a
beautiful airplane. The leather interior is really well done (and smells
good, too.)
You can read all about it in SA. One of the things that he'd done that I
thought was pretty clever was mentioned in the article. It's the joggle
that he put in the rear of the forward fuselage skin. The forward part of
the tip up nests into this joggle almost perfectly and because he used the
goose neck hinges, he said he has absolutely no air or water leaks. Of
course, this idea would not work if you choose to have the canopy side skins
overlap the fuselage. Craig's canopy butts against the fuselage side rails,
per plans.
I told Craig about the RV fly in at Burlington, CO on Sept. 28th and he
said he'd try to get there.

Guys,
Jerry Scott (the 85 day Oshkosh 95 RV6A) also does something
similar, but slightly easier to fabricate. I saw several RV6 fuselages in
his shop during the Chino, CA fly-in and they all had the following
modification.
When he fabricates the F-668 bulkhead (the aft end of the fixed
forward top skin), he places a strip of aluminum (about 7/8 wide - 0.025 or
0.032) in between the top flange of the F-688 and upper deck skin. With
about a 1/4 inch of this strip exposed after the skin is attached, a nice
'ledge' is formed for the canopy forward skin to close against. This is
instead of the canopy forward skin resting on the 3/16 radiused corner of
the F-688. It also gets around the 'disappearing' 3/16 radius as you get
closer to the longerons (caused by the taper of the forward fuselage -- see
the archives). Since the F-688 is spliced from L and R parts, and notched
for the longerons, it can be easily adjusted to allow for this extra strip
over the F-688.
It seemed a really good idea to me, but unfortuneately came to late
for incorporation on my fuselage .... :^( .... it would have also saved
quite a bit of "fiddle time" and well as looking neater and providing a
better air/water seal.
... hope it helps someone else ... Gil (too late) Alexander

Bill has other problems, but I thought I'd pass this on for other tip-up
canopy builders ....
I had asked the same question, and got three equally good
responses. The concensus agrees that the plans are deficient in this area
and something is needed.
1. Just crease inwards (mash in) the canopy deck where the transition from
side to forward deck occurs (the Bob Skinner and John Darby approach).
2. Cut a vertical notch similar to that shown on the plans for the sliding
canopy in the same area (the Jim Stugart approach, I think)
3. Cut a slit in the forward canopy deck that is just (about 1/16) below
the edge of the plexi. Start the slit at the aft edge of the forward
canopy deck, and cut it about 4 inches long. End it in a nice stress
relieving hole. At the aft end, just above the slit, pull in the aluminum
and rivet it with a flush rivet to the canopy side rail. The blending you
need will now occur smoothly along this 4 inches from the canopy side rail
to the end of the slit. (the Alexander approach - suggested by another
RV-list member)
... hope this helps other builders ...

I'm getting ready to install the flaps on my quickbuild RV-6A when I
notice that the factory installed the piano hinge upside down... on both
flaps. The hinge extends about 1/16" below the wing, when it should be
tucked up inside the wing. Hmmmm 1/16" times 56" flaps times 2 wings
equals 7 square inches of drag from this little factory snafu. What would
you do? Drill out 80 rivets? Accept the drag? Comments welcome!
Thanks,
Tim

One feature that surprised me about the LOM engine I am flying is the
crankcase breather tube. It is about 3/4" I.D. and is about 6" short of
reaching the cowl air exhaust outlet. After 100 hours of flight, the inside
of the tube is still dry.
These new dry sump engines are really different from the old "wet sump"
engine design. :-)

It use to be that after the number four cylinder pipe cracked the first time,
you would send it back to Tolle for a slip joint in this pipe. I don't know
if they are still doing this.
BTW, I seem to remember that this occured on about 10% of the Tolle exhaust
systems.

A heavenly scene in the far distant future:
Van went to Heaven upon his death and was given a warm welcome at the
Pearly Gates. St. Peter, after completing the formalities, asked him how
he would like to spend his time. Van, the great inventor, asked to see
some of the inventors before him. So St. Peter printed out the list of
all the inventors currently (doing time) in heaven.
As Van started to go through the list, he came across the name Adam. He
queried if it was the same guy who discovered Eve, the woman. St. Peter
confirmed that indeed Adam was the man credited with the invention of
women. Van requested an audience with Adam, as he had a few things to
straighten out with him.
When the scheduled meeting took place, Van was all over Adam, attacking
him for the flaws in his invention.
"Your invention is the most stupid work of engineering I ever saw. There
is too much of front end protrusion, the rear end wobbles too much, it
chatters at high speeds and the intake is placed too close to the
exhaust."
Obviously, Adam doesn't like it too much. He thinks for a while and then
leads Van to the Celestial Computer. He works with the enormous
data-banks and in a few minutes there are beeps and all that, and out
come a few charts and graphs.
"Look here, Van. Despite all the flaws you pointed out, data shows that
there are more men riding my product than yours."

RVers, I just got off the phone with John Stewart concerning the Fly-in on
Sept. 28th in Burlington, CO. This fly-in sounds like it's shaping up to be
a pretty big deal. 19 RVs from Texas, Bob & Judy Avery and GEORGE and Becki
Orndorff (right George?), Keith Ellis and others from Boone, Iowa and I'm
sure, a host of others, maybe even a few from Nebraska. It's shaping up to
be an exciting event.

I've seen this on more than a few -4's. All continue to fly with no problems.
I have no explanation, except that where the gear legs tie into the center
floor ribs might have been a bit out of whack, previous to the aircraft
adjusting itself. Do to this being a possibility, I'm suggesting the
following:
When you jig your fuselage, attach the motor mount to the firewall, and jig
that as an assembly. In assembly, attach the floor ribs to the 063 angles
previously riveted to the firewall with #8 washer head screws, same # and
spacing as rivets. Due to the method for attaching the inner/upper gear leg
mounts on the -4, any minor mis-alignment here will stress the firewall/floor
rib area. If you have your fuselage already built, shim the area mentioned to
take up any slack- do not simply tighten the bolts.
Comments?
Check six!

Subject: | Re: Upside down flap hinges |
The step created by the hinge is rounded and located well back on the
surface of the wing where the boundary layer begins to thicken.
The frontal area is 7 inches (.05 ft^2). The equivalent flat plate
area is the product of Drag Coefficient CD and frontal area.
It is the latter that slows you down. I would be surprised if CD for a
step like this was greater than .1 giving a flat plate area of .005
ft^2.
At 175 knots the dynamic pressure is 103 lb/ft^2, the drag of this
excrescence is on the order of .5 lb. Total airframe drag is about 200
pounds. You probably wouldn't notice it.
Since you have the quick build kit and have not developed the shakes
at the thought of having to do yet another thing over, go ahead and
fix it. Besides, it builds character.
Drilling out AN426 3 rivets is not too difficult. Practice on a dozen
set in scrap first. Either a new hinge or a .063 packer under the
original will restore the surface.

Gosh, Ernie, I didn't think I was advocating not putting in the notch:)

a good practice). <
I probably should have left off my "IMO". I have a "blow hole" in my
installation. However, I've seen homebuilts certified that do not have this
"whistle notch" (but then, I saw a RV-6A certified that didn't have the two
bolts holding on the mechanical fuel pump safety wired. It didn't have the
blow hole either. Guess the Feds can't inspect everything). When the
discharge is located 1/4" from the exhaust pipe, I don't think there is much
chance of a freeze up and just because there is a whistle notch does not
mean that the system is 100% protected from freeze up. Also, putting the
notch in the tube might not be as easy as it first seems if you are going
"by the book" . It seems that I've read that there is a specific size/shape
and/or location that these should be for proper operation. Can't remember
where I read the specs.
The best way I've found to prevent condensation from freezing in the
breather line is to fly the dickens out of the RV-6 and burn that moisture
out of the oil:) It's worked for me, so far, anyway. Bob Skinner RV-6

======================
Hi Capt Tim,
I think I would go ahead, drill it out and install it correctly. Simply
because when you'll wash your award wining bird the rag will snag on the
end of the hinge....... This will come to annoy you. Besides it will look
better and you have confidence knowing you did it right. Am I picky are
what?
ps. don't forget to rivet the new hinge assembly in with the pin and
opposite hinge in place to help keep things lined up.
happy building
