Len,
How much oil are you starting with???
Many of these Lycomings will "blow out" the 8th (or even 7th) quart of oil.
I have found that once they get around 6.5 quarts, the bottom seems to
remain clean and the perceived oil "consumption" seems to stabilize.
Your mileage may vary.
James

--> RV-List message posted by: "George McNutt" <gmcnutt@intergate.ca>
--> RV-List message posted by: -------
--------------big snip ---------------------
It just irritates the hell out of me when I hear people say well I might
be in a situation where I can't help flying into some kind of adverse
weather, that is total BS, anyone with their eyeballs open can see what
kind of weather they are flying in and take preventative action.
Anyone that flies into know weather conditions beyond their experience
or the ability of their aircraft should maybe take up basket weaving.
I guess with this one I better get out the old flame suit.
-----------------------------
(1) Eyeballs!
Yes - since you suggested it here is your flame, and possibly a new
discussion.
- It would not be good PR for flight schools or the aviation industry to
advertise the fact that the human visual system is one of the weakest
components of our VFR flight system. There are many situations where you, or
myself, could fly into the ground, water, cloud or another aircraft without
being able to detect same with our mark one eyeballs!!
If you disagree try flying across Greenland without your altimeter.
The next time you line up on the runway remember that your depth perception
system reaches all the way out to the first runway light, your judgment of
how far away distant objects are is based on experience not your eyeballs,
judging your distance from some cloud is impossible.
Unfortunately life is to short to experience all the lighting, weather, and
optical illusions that one can encounter in flying, however experience and
training can prevent many of the risks associated with our inadequate
(20/20) mark one eyeballs.
(2) Carb Heat
- the FAR's say that at 30 degrees F. your carb heat must produce a 90
degree F rise at 75% power, I have never had a certified light aircraft
(with CAT gauge) that could produce that much heat.
I would be interested in hearing from others how much temperature rise their
RV's (with CAT) are getting when carb heat is selected on.
In flight my carb temp shows about 10 deg F cooler than the OAT gauge and I
get about a 15 degree F rise in CAT in flight when the carb heat is selected
on. On run up on my 6A (0-320) I have a 30 RPM drop when carb heat is
selected on. I have a custom heat muff about 8" long on one crossover pipe
and plan a new larger carb heat muff surrounding both crossover pipes.
In flight I am getting higher carb temperature readings with carb heat at
low power settings (approach) than I do at cruise power.
(3) And the answer as to when carb heat could raise the temperature to the
point where carb ice could occur, - when flying in ice crystals.

I've taken some still photos and movies shots (mpgs) recently from the back
of an RV 8 and most if not all the "outside the cockpit" shots came out fine
during the daytime but not very well at night. I used an Olympus D510
digital camera. I didn't use any special settings but you might try
ensuring your camera is as perpendicular to the canopy as possible, as close
to the canopy as possible and maybe even preset your focus to infinity.

Thanks for the report. With the information available at present, I will opt
for the Whirl Wind 150. Weight reduction is the main inducement.
In your report, above the TOP SPEED table, you say "lower OAT will yield
higher power" . How do you account for the 10 degree OAT difference in the
cruise table?

Many of you are aware that I have been in search of a prop upgrade for my

compiled as to how it compares with the Hartzell HC-C2YK-1BF. The updated
info on this process can be found at...
www.rv-8.com/Prop.htm
This is only the first half of the process, as you will read on the above

Hope you find it informative and/or useful.

Dan:
First guess is that brake master cylinder return springs are not fully
pushing the plunger all the way back up. Try this when you encounter the
problem again. Reach down and grab the brake pedals and pull them all the
way aft. If you feel them move and if this solves the problem, you have
isolated it to the return springs. See what happens and advise.

I just bought the one from Van for my -8A and it works fine. However, I intend
to modify the skirt portion, which is a little on the loose side. May sew in
some darts and/or add a small bungee cord.

I am having a little trouble picturing this setup. I think you are saying that
this FAB has one mesh screen at the point where the scat tube from the carb heat
muff enters the FAB and a second one on the base of the carburetor. If this is
the setup, I'm puzzled at the existence of the screens. In the current design,
all flow to the engine has to pass through the air filter anyway, so what are the
screens supposed to accomplish? Maybe I just did not get a correct mental
picture of this air box.

I don't know about a guy in Michigan, but are you maybe thinking about
the Headsets Inc people? They are in Amarillo, TX and have a mod for
Dave Clarks which turn them into ANR headsets. If this is what you have
in mind .. more info can be found at http://www.headsetsinc.com/.
If this is NOT what you have in mind, then what does the guy in Michigan
do with DC headsets?? Just curious.

see where it would stop putting out oil on the belly. I now keep it at 6
quarts but still get it on the belly. I got a note from Kyle about the
orientation of the bevel in the breather tube and I am going to check that
next.

Good question, I don't know how to mathematically compensate for it. Van saw
my data and said that he thought it wouldn't make that much difference, and
that when taken in context with the rest of the tests he thought it was
probably an accurate reflection. Of course there's always a +/- tolerance
involved, none of this testing is perfect.

Gee Gorge I guess maybe if that is the case I just as well put on
blinders and go fly. :-) Yes eyeballs can be tricked, BUT in the end
it is still a see and be seen environment. I am not talking necessarily
about judging distances from clouds I am talking about seeing the damn
thing in the first place. It is not judging distance from them that is
the problem it is idiots sitting there in the cockpit fat dumb and happy
and pushing into weather they or their airplane have no business flying
into. My goal is to have people set limits for their themselves based on
their experience. If a person does not have experience to judge how far
they are from the clouds or any situation they don't have experience
with stay away from it tell you can make a informed decision. I agree
with you that experience and training and I might add common sense are
the key to long flying carriers. If it seems I am harping on this
weather and ability thing it is because I have lost more friends by
flying into weather situations than any other aspect of flying.

Are you using the FAB from Van? All the heat in the world well not do

In thinking over the situation I can see how a alternate air source may

I had an airplane one time (not an RV) that kept what I thought was
blowing oil out of the breather. What I discovered was that the breather
tube was to long and a venturi effect was sucking the oil right out of
the engine. Once I shortend the breather tube it stopped.

The venturi effect is exactly what happens if you create a venturi by
misinstalling the breather tube and by providing a source (such as a loose
dipstick) so the venturi can draw air and oil through your engine.

You have hit on a problem that has bothered me too for a long time. I just read
over a synopsis of RV accidents from about 1996 through 2000 and was amazed at
the
number of them caused by either poor judgment or outright stupidity. And the sad
part is that this has gone on in aviation since Day 1.
For instance, how do you convince an individual to land with an hour fuel
remaining as a way of never landing with dry tanks? We all know this and yet you
would not believe the number of airplanes in the listing that have come to grief
because of this exact problem. Many times the pilot later said that the fuel
gauges said he had fuel! We are taught not to trust fuel gauges but to use them
against time and known start quantity as a cross check. What causes pilots to
continue to do this?
Another high item on the list is accidents involving buzzing one's house, business
or gathering of friends. I have read these scenarios so many times that I can't
help but think about them anytime I have notions about doing this. Yes, out in
the boonies I'll get low and fast after looking over the area first from
altitude. But I actually think about it and realize that I have read the results
of doing this without good planning and options.
Options -- to me that is the real issue. If you could only teach pilots to
maintain options and evaluate them when necessary you would go a long way to
addressing these safety issues. After all, isn't judgment primarily maintaining
a
list of options and then going to the best one when the situation dictates?
Flying into lowering weather with diminishing light, mountains ahead and a
temperature/dewpoint spread of zero in a VFR airplane has pretty well taken the
options list down to one -- crash. It had been much longer earlier.
After 9/11 and the restrictions put on our flying (many I think unnecessarily),
I
have become more aware of how free we are to fly and how much we have to lose.
If
John Q. Public learned that a person could build an airplane in his garage, meet
a
test flight regimen and then without anyone's permission or clearance fly right
over the top of LAX as I do a couple of times a week, he would be up in arms and
demand that government "do something about it."
If somehow we could magically reduce the stupid pilot stunts and the foolish
squandering of one's options down to one, we could much better insure our freedom
to fly for a long time to come. How that can be done has been, is now and will
continue to be one of the toughest challenges in general aviation, at least as
I
see it.

Feel the disc (carefully) if they are REAL hot, you may have the pads

Well said Bill, I have been thinking about this alternate air source a
lot and agree that it could be benificial. I just do not like what I
have seen so far. I do not remember if it was yours or someone else's
that has the hinge inside the filter that makes me nervous knowing how
these hinges wear with vibtation it would certainly have to be a high
inspection area. There has to be a way to do this with some type of
filtering system for the alternate air. I know of one airplane that did
serious engine damage by injesting parts and I have had emails from
others on the list saying they know of others. These are not all RV's
but the results are the same.

Nope, not mine. In fact, I do not yet have an alternate system installed. I am
standing back on the sidelines, seeing what Van and everyone else does, and learn
from
that. My defense right now is just that I understand the problem. With that
as a
known factor, I make weather decisions accordingly.

I've been flying since 1967. Mostly Mooney. PPL ay 70 hrs IFR at 90 hrs flown
48
states, Caribbean, and Canada.
My personal opinion... for what it is worth.... No VFR pilot should be up in anything
less than absolute CAVU unless he is trained and comfortable under instrument
conditions. This includes night VFR.
I have had at least three incidents when rain started to fall from high overcast
into
high humid air and the visibility went to 1/4 mile in less than a minute. 300
radios
all screamed at Center for vectors to the nearest AP and all center did was repeat
over and over "Stay VFR until you have clearance, file with blah blah blah" In
each
case I wanted to get out of all the blind traffic so shot a VOR APR at the nearest
field and broadcast my intentions in the blind on APP and then TWR freq.
I have had the same thing with the beginning of snow, unperfected, and maybe it
evaporates before reaching the ground, but don't count on it. Flying at 8 or 10,000
ft you can't tell either the extent or density of what may occur in any direction.
Please. get IFR training (I don't care whether you get certified so you can file
IFR
flight plans) but that way, we and the non flying public won't have to read about
another fool that "flew, controlled flight into terrain under ICW conditions".
It
hurts all the GA survivors.

Dan, is this a new airplane? The brake disks come from Van's with a
coat of paint on them, which should be removed with lacquer thinner or
similar before being used. Paint goo could be the problem.

My engine is fuel injected so carb heat as such will not be needed but I may
design such for anti intake ice?
I will install a flapper or similar device which will switch to a totally
alternate air supply, probably air drawn from within the cowl. An
snow as well as FOD or birds could totally clog the main intake, fine, switch
to the alternate. The alternate does not have to be efficient or filtered, it
just needs to provide enough air to keep the engine happy.
I have an Instrument rating. What I learned from getting an Instrument rating
is that I want no part of flying in clouds/poor conditions in small airplanes
as if I did not know that before. Flying in ideal conditions is not possible
all the time but pilots must set limits and then adhere to them.
Yes, landing with a 45 minute reserve is a good idea and the worse the
potential weather is the more conservative that number should become. Do Not

Randy,
I took a look at your comparative data, and offer the following rough
corrections for the differences in temperature and weight between the
different configurations:
Climb data - the mid-altitude for your climbs was 3500 ft. The
Lycoming power chart suggests the full throttle MP would be about
25.5", and the power would be about 166 hp for both sets of tests.
The RV-6A CAFE report suggests about 138 lb of drag for an RV-6A at
1650 lb. Assuming that drag varies linearly with weight, that gives
a drag of about 143 lb at 1704 lb. The RV-8 should be a tiny bit
cleaner than the RV-6A, so I'll assume 142 lb of drag for the tests
with the Hartzell. 120 mph CAS at 3500 ft at 40 deg F gives about
125 mph TAS, or about 125 x 5280 / 3600 = 183 ft/sec. 142 lb x 183
ft/sec / 550 ft-lb/sec/hp = 47.3 hp required to maintain level flight.
You measured a temperature of about 40 deg F, which is a bit colder
than standard temperature. With non-standard temperatures there is a
barometric altitude error to correct for (i.e. 1000 of barometric
altitude change is actually a bit less than 1000 ft real altitude
change). You measured a barometric climb rate of 1659 ft/min with
the Hartzell. We need to multiply your measured rate of climb by
the ratio of actual temperature to the standard temperature for this
altitude, with both values express as absolute temperatures. Using
degrees Kelvin, this translates to a real climb rate of 1659 x (277.6
/ 288.12) = 1598 actual feet per minute.
Now, rate of climb = excess power (x 33,000 ft-lb/hp) / weight. Or,
excess power = rate of climb x weight / 33,000. 1598 x 1704 / 33,000
= 82.5 hp. 47.3 hp required for level flight + 82.5 hp excess for
the climb = 129.5 hp that must be produced by the prop. If the
engine was producing 166 hp, and the prop produced 129.8 hp, that
means the prop efficiency was about 78.3%, which is quite believable.
On a standard day, the engine would be producing a bit less power,
and the TAS would be a bit higher (which means a bit more power is
required to maintain level flight). That translates to a predicted
rate of climb at 1704 lb of about 1575 ft/min, or about 23 ft/min
less than at the test conditions.
With the Whirlwind prop, I calculate a real rate of climb at the test
conditions of about 1645 ft/min, and a prop efficiency of about
76.8%. At 1704 lb on a standard day, that gives a predicted rate of
climb of about 1525 ft/min. So, if you assume the test data is 100%
accurate to a gazillion decimal places, you would say the Whirlwind
150 produced about a 50 ft/min rate of climb loss compared to the
Hartzell. In reality, there is always a bit of inaccuracy in test
data, so the actual performance difference could be a bit different
from this calculation.
I'll attack the cruise data later - my wife has a long list of things
she thinks I need to do, and I've avoided her about as long as I can
get away with for now.
Cavaet - I haven't done this type of calculation since test pilot
school - now days I let my flight test engineer worry about crunching
the numbers. So, there is certainly a risk that I've fouled this up
slightly, and some careful guy may be able to point his finger at an
error.

It can be done.
The installation manual describes how it is done.
I have done this, except mine goes into the SL15MS... but the GX65 will
allow it also.

Bernie Kerr, 6A flying, 9A rotary building, SE Fla ( ice is not my
expertise )
Bernie is correct. You will not increase the likelihood of forming ice by raising
the temperature of a given mass of air. The reason one sample of 45 degree
air will form carb ice, and another sample of cooler air will not would be because
the 45 degree air has more moisture in it.
If you take a mass of air at a lower temperature, and heat it up without adding
any moisture, the relative humidity goes down, and so does the chance of forming
ice.
Rather than modify the system to bypass the filter, I would rather install a carb
heat system which effectively raises the air temperature. The systems I see
on many RV's look poor in that respect to me. It appears that most of the heating
is due to the air having passed over the cylinders, not due to briefly
passing the exhaust pipe.
I guess these systems have been in common use because Lycomings are not very susceptible
to carb ice due to the intake design.
I plan to make a carb heat muff that will do a more effective job of heating the
air.

Oh, I really hate to read that kind of opinion. I'm a 1860+ hour VFR pilot
who has never turned in a claim on my insurance and has never dinged an
airplane other than normal wear and tear. I've got almost 1000 hours of
cross country time and quite a bit of night flight, as well. I think I'd
rather be in command of the airplane I'm in than to be in one with a IFR
pilot who flys every once in a while. Let's not forget those professional
folks who fly their Bonanzas into the soup and kill themselves and their
families just because they have that IFR rating. Be careful how you express
your opinions on this list. The toes you step on may be the ones who will
come back to haunt you. It's not what ratings we have that counts. It's
how we use them.

Len,
I don't think this was mentioned.........but most folks have a
'whistle hole' in the breather tube. This will break any 'venturi' effect
created by the passing air. I have a 1/2" ID metal tube about 16" long bent
at about 70deg that the breather hose goes into. The other end is clamped to
the upper 'side' of the exhaust pipe per Vans. The 'whistle hole' (1/4") is
on the 'inside' at the start of the radius of the bend. No separator......no
venturi.......no oil on belly.

Air-box advisory, carb heat & mixture subject: As any of you know who
have flown with me or listened to my talks, I am the original "mixture-EGT
nut". The point I try to make is that declining EGT is usually your first
hint of carb ice. Carb ice is likely to make the mixture richer and cause
the EGT to drop. This will usually be before you detect any loss of power,
as the richer mixture will mask the power loss for awhile. Keep in mind that
EGT is necessary to get rid of the ice!
EGT is just like money: you need it most when you don't have any! OK,
I'll get off the soapbox now, but I wouldn't fly without good visual
indication of EGT. Your mileage may vary!! Paul S.

I know of two RV-6s, one with an IO-360 and one with an IO-320 which have
automatic, spring loaded doors in the induction system downstream of the air

First of all quit taxiing and start flying. If you have a new or
overhauled engine taxiing is the worst thing you could possibly do to it.
As for the brakes; Depending on how old your parts are there was a mess
of Cleveland cylinders with weak springs that needed replacement. The
matco master cylinders (internal spring) is now standard and this
problem does not apply. I find that many builders install all the
hardware a little to tight on the pedals so to keep the loose play to a
minimum. This is about the only place where you want everything a little
loose so that there can be no binding of the pedals. Make sure
everything is loose, and if you have the external springs then maybe you
need new replacements.
One post mentioned the paint on the disks as a possible problem. I think
the paint rubs off on the first application of brakes but this could
possibly add to the problem. Also if the brakes are dragging so bad that
you cannot push the plane then they are real hot too. This can be hard
on the seals. I had one dragging and it got hot enough to melt the
elastic insert in the fiber locknuts. Ruined the internal seal too.

The crosslink is a necessary component. You can calculate the ratio for mix

Mike,
I know that you found your problem but just a comment about the "whistle slot"
for others that might have a similar
problem.
The whistle slot also breaks the suction that you will have in the tube if it exits
in a low pressure area. I had this
problem on my Stinson and it was completely cured by the whistle slot. The slot
should be well up into the cowling in
an area of relatively high pressure.

John Harmon of Harmon Rocket Fame and his wife stopped by Apple Valley

he stated that there was a hangar fire and three Harmon Rockets under

Sorry, I don't remember where and don't know any of the names, but my best

The Lycoming performance chart has in fine print a 0.1" mp correct for each
10 degrees f of temperature difference for the standard temperature.
So for your 10 degrees difference in OAT (degrees f?), it would be the same
as 0.1" mp. Higher Temp = lower MP. Lower Temp = higher MP.
My interpretation of the Lycoming chart is that engine performance show be
based on density altitude. I been using full throttle at 7,500 feet density
altitude as a performance standard.

| Subject: | Sensenich Prop (was Prop testing data posted) |
--> RV-List message posted by: "Stein Bruch" <stein@steinair.com>
Hey guys,
Speaking of prop testing data, I have a similar (but different) question. I
know this thread has been about C/S props, but mine is about the FP
Sensenich. Here's my question,
Has anyone twinted these beyone 85"?????
I ask because of my data:
I have a 180hp AEIO-360/B4A Lyc swinging an 85" sensenich.
Static RPM 2250 - Full throttle up to 10.5K I can easily run to 2750-2800+
RPM.
I have a solid (aerobatic) crank, so I can't use a C/S, but I'm wondering if
I can put in a couple more inches of twist without harming the prop.
#1) Is this wise?
#2) Would I lose too much static RPM to offset the top end gain?
Basically I'm just looking for a way to utilize some more hp at slower
RPM's. I don't cruise around at 2750-2800RPM, usually around 2500. My
engine is used, came off a Pitts, and I suspect it may be putting out a bit
more HP than I originally thought. The logs are a bit vague about what was
done at the last OH (600hrs ago), so I don't know if it's stock or not, I
just know it runs like a banshee!
Thanks in advance for any tips,
Stein Bruch
RV6, Minneapolis.
Oh, and YES the C/S guys can out-climb me, but I keep up just fine (or
better) on the top end.

Yes, I haver seen similar designs, thanks for the tip. This alternate air
thing is an obvious need and I am sure I will be corrected but on aircraft
such as single engine Cessna aircraft the alternate air is the unfiltered air
supplied via the carb heat. Just because carb heat is not a needed item on a
fuel injected engine does not mean I cannot install a similar two-way box,
one inlet from the air filter and the other straight from within the cowl.
This is not rocket science, it is really very simple, and nothing against
Vans or anyone else but since I am the manufacturer mine will have alternate
air regardless of what Van or anyone else does with theirs. I saw a bird
jammed in the inlet of a Grumman once, a grackel, darned if that Grumman
wasn't mine, there was a couple of more that wound up on top of the engine
also and a bunch of feathers and some bloody spots on the wing, that carb
heat did fine for me. Do not archive. JR
