At this time of year wait till OSH and either go and get one yourself or get
someone else who is going to get it for you..... I got my 295 there last
year for a price I couldn't match anywhere on the Web and about "half the

I'm building in a 15 1/2 X 21 1/2 (inside dimensions of 16 X 22 garage). I
have mounted one wing at a time to get it final drilled, but just barely
enough room. I think I will be able to get the engine and tail mounted on
the fuselage by angling the plane across the area but I can always wait on
the tail because I have had it fitted and have removed it for ease of
working on other parts/areas. My backup plan to move into my double garage
and move my wife's car outside (but that will have to be her idea and not
mine if you understand what I mean).
Do Not Archive the stuff about the backup plan.

--> RV-List message posted by: Don.Alexander@AstenJohnson.com
Although I am still a fuselage away from ordering my engine, the research
has started. I have a question for the wrenchheads on the List. I am
considering Bart's XP-360 with a slight modification. I would like to have
it made with lower compression jugs to permit the option of using auto fuel
if the need arises. Aero Sport says that this is not a problem and that
the final compression ratio would be around 7.5:1 for an estimated output
of 170 hp in the carbureted version. Aero Sport indicates that 80 /87
Octane would be appropriate. I am planning on using a Whirlwind 150 series
C.S. prop with this engine.
Now for the questions:
1) Is this a stupid thing to do? All opinions are welcome.
2) Any issues with lower compression jugs and prop harmonics. or are the
harmonics a function of higher compression levels?
3) Does auto fuel damage any component of the fuel system?
4) Do the valves need a steady diet of lead in the fuel for any reason,
and if so, would an occasional run with 100LL keep things happy?
5) AeroSport's suggestion of 80/87 octane has confused me. Does this mean
that I could run 89 or 91 octane auto fuel, or is the 80/87 some sort of
avgas that I have not run across yet?
6) Anything else to consider?
I am building a RV-8 (Yes, I have decided to go with the taildragger since
obtaining my tailwheel endorsement last month.) and think that 170 hp
should be enough to keep up with the local spam canners. My ship is going
to be one of the lightest out there due to a secret modification that I am
undertaking. Since you all are going to be generous enough to give me lots
of help with my engine questions, I am going to share my revolutionary
"lightness" design with the List. I ask that you not leak this design to
the media or to anyone outside of the RV community. Here it is:
I have constructed air bladders inside every bay of my wings and tail. I
will do the same for my fuselage. Each of these bladders will be filled
with Helium. (Hydrogen is cheaper, but that Hindenberg thing sort of
tilted the balance in favor of Helium.) Each of these bladders will be
fitted with a bleed-off valve in order to keep the bladders from exploding
as the atmospheric pressure drops at altitude per the latest thread on the
List about carrying liquids with air space in the containers. I will also
fill my tires with Helium for additional weight savings. My calculations
indicate that I will need a person holding down each wing as I taxi to keep
her from leaping into the air.
Seriously, though...my secret to a light airplane is that my genetic makeup
has kept my "gross" weight at 145 lbs. (That's 11 Kilometers to our metric
brothers and sisters) At 145 lbs, I will probably need wing walkers to
keep her down while I taxi!!!
Thanks in advance for the engine help

--> RV-List message posted by: GRENIER@aol.com
The New England Wing of Van's Air Force has determined that June 21th. is the
perfect time to celebrate their second annual RV fly-in. The event will be
held at the Nashua, NH airport (ASH), and activities will start at 10 AM.
This year program organizers have decided to focus on key areas that
influence the completion and safe operation these extraordinary airplanes.
Presentations will include the introduction of new and very cost effective autopilot
system designed by one of our members, a discussion of acrobatic flight
maneuvers, a briefing on the issues leading to the award of the airworthy certificate
and the proper preparation for the first flight and performance evaluation. A
Wings program, Spatial Disorientation, is also being offered and will include
the opportunity for pilots to test their own tolerance in the spinning chair.
A cook out is scheduled at noon and everyone will have the opportunity to
check out a variety of completed RVs and check out a few under construction.
Arriving aircraft will receive specific taxi and parking instructions on ADIZ.
If the weather doesn't cooperate, the alternate date is June 28th. RV pilots
and builders within the region and encouraged to spread the word and their
wings to help us make this event a success.

--> RV-List message posted by: "Patrick Kelley" <webmaster@flion.com>
It all depends on your situation and planning abilities. Luxury would
be a hangar or at least a workarea big enough to hold the assembled
aircraft with 3' all around. However, as others have already mentioned,
many RVs are being built in single-car garages or less. I built my tail
and wings in an apartment living room by having the painting done for me
and moving outside for some operations like prosealing the tanks and
riveting the spars. This required planning to work around the weather
in Michigan. There was not enough room to build the fuselage there, so
I had to wait until I had a garage. Now I am constructing the fuselage
in one half of a two car garage. When the time comes to mate the wings,
I will either do one wing at a time by moving the car from the other
side and moving the fuselage around or I will plan it so that it occurs
during good weather and mate the wings in the driveway. Once the wings
are fitted, they come back off and need not be fitted again until
assembly at the airport. See Dan Checkoway's website for this, or the
Orndorff videos, where George and Becki roll their wingless fuselage
into the back yard, plumb plastic tanks to the fuel system, and fire up
the engine.
Bottom line, a two-car garage of any dimension will work for an RV.

I know this is probably a dumb question but I'm contemplating purchasing
the
RV-7 kit and I'm not sure I have enough room to build. I've read the
standard reference to a '2 car garage' but this is too vague. I have a
newer condo with a two car garage but it only measures about 20'x19'.
Is
this enough square footage? The garage has two separate 'doors' with
about
a 4 foot 'wall' between them so I know final assembly in the garage is
out
of the question.
Thanks....

Just an FYI for the list: I'm currently wrestling with an email virus
and I don't know where I may have picked it up. Since most of my
incoming mail is RV-related, I'm posting this warning so that people
will check out their own systems.
The virus in question creates bogus messages in my email client's
(Netscape) inbox, with blank subject fields and no contents. If those
messages aren't deleted before viewing a real message, then the rest of
the real messages in the inbox will be corrupted or deleted. I've tried
McAfee & Symantec anti-virus utilities with zero success and I'm
starting to get frustrated with this.
If anyone has any idea what this virus might be and can propose a viable
solution, I'd be very grateful. You'd think people would have better
things to do than to cause random mayhem for strangers. Virus coders
should all be stood against a wall and shot.

1) Is this a stupid thing to do? All opinions are welcome.
>>A friend of mine did just that for his Bearhawk. He had an O-360 engine built
with low compression pistons so he can burn Auto-Gas, however he also used the
Angle Valve Cylinders of an IO-360 in his mix of parts.
Q: Does anyone on this list know how much of a difference there is in breathing
capability between parallel vs. angle valve heads, or any other pros & cons
for one over the other ???
2) Any issues with lower compression jugs and prop harmonics. or are the
harmonics a function of higher compression levels?
>>Don't know for sure, but think that a lower pressure powerpulse would make things
easier, (as it has the opposite effect of all the current warnings against
High Compr. & Electronic Ignitions)
3) Does auto fuel damage any component of the fuel system?
>>Only the oxygenated (winter type) fuel's may give you problems with some rubber/plastic
components. Do your research on every component that goes into your
aircraft for compatibility, though.
4) Do the valves need a steady diet of lead in the fuel for any reason,
and if so, would an occasional run with 100LL keep things happy?
>>Run every forth tank or so on 100LL to resupply lead to the valves (or run a
25%-75% mix)
For more deatailed Auto Gas info, see these websites:
WWW.AUTOFUELSTC.COM or WWW.EAA.ORG
5) AeroSport's suggestion of 80/87 octane has confused me. Does this mean
that I could run 89 or 91 octane auto fuel, or is the 80/87 some sort of
avgas that I have not run across yet?
>>Next time you fill up your car look at the sticker on the pump for an explanation
on how Octane is expained/measured (RON+MON : 2)
6) Anything else to consider?
>>A dedicated Saving Account for all the Money saved!

Don,
I am no "wrenchhead" but why don't you just get the "regular" engine from
Bart and use "premium" autogas?
You **WILL** wish you had that extra 10 or so HP at some point.

I would be prone not to believe someones data plate. I believe the engine
is probably putting out more like 160 h.p. If the engine has sat for
awhile, it probably is okay if he kept the oil in it. However to give you
my personal take on it. You are going to be the one flying behind that
powerplant. An 0320 is a good engine (as long as it has two independant
mags. I would after purchase dissassemble and send the case halves, sump
and accessory case to Divco in Tulsa, have them line bore & size the cases.
send the crank and cam and connecting rods also and have them NDT'd and
magna fluxed. replace all bearings and purchase a cam outright brand new.
Put everything back together and you will have the knowledge and comfort of
knowing that the engine is sound.

If I build another I will build as much of each component as possible in
the garage. The garage is close to the house. My progress on Valentine
(N7HK) declined very sharply when I moved to the hangar. I should mention
that the hangar was an hour and a half away.
The builder's most important tool is persistence. Ideally, one would have
a workspace with a cot and someone to serve food, coffee, beer etc. And a
portapotty. At the airport, attach wings, engine etc and go.
Others who have done it -- is it reasonable to haul a modern nosewheel
airplane with engine mounted?

--> RV-List message posted by: "Randall Henderson" <randallh@attbi.com>
When I first got my plane flying fuel pressure with the aux pump off
generally ran pretty low, spending much of its time betwen 1/2 and 3 PSI.
But lately it's been creeping up, and the other day I saw it pegged up at
14PSI. What's going on? This is a normally aspirated Lyc. O-360 (carb,
magnetos, no primer). Indications are with the electric fuel pump OFF. FP
gauge is a Mitchell "steam-gauge" type, with a remote sender on the firewall
plumbed to the carb fuel intake. No other problems detected, just the high
reading.

80/87 is the red-dyed avgas. I guess it is rare enough these days that there

I read an article that I can't find right now that basically said that the ONLY

and therefore get more horse power. EVERYTHING else
about the lead was bad for your engine. If I remember right he said that the only

Just a note on the "spinning chair". (1) Make sure the pilots are well
strapped in--even very experienced aviators have a tendency to throw
themselves to the floor and keep on spinning, once the chair stops--(2)
Have *lots* of barf bags--(3) Be very nice to the folks after they

Sounds like a John Deakin article which can be found on AvWeb. If you want
to see it, the URL is http://www.avweb.com/news/columns/182149-1.html though

Randall,
Yes, they are adjustable but they all seem to be different. The one I
got from Van's was off about 8 mph and I was able to correct it so it
was pretty close across the scale.
You'll just have to look at it and figure out how it's adjusted. Mine
has a flat spring with a series of set screws along it, each one
adjusting a different part of the range and you have to start at the low
end. I've been fiddling with instruments for 30 years and I don't think
that I've run across 2 ASI 's that were the same yet.

The virus in question creates bogus messages in my email client's

If anyone has any idea what this virus might be and can propose a viable

| Subject: | Propeller choice |
--> RV-List message posted by: Chris W <chrisw3@cox.net>
I was reading about this engine that, unlike most talked about, is a
true alternative to the standard Lycoming. It is able to produce a
maximum of 200 hp at only 2,000 RPM. Granted it may never be a reality
but I was wondering if it were, what would that mean for propeller
choice? Would you just increase the pitch or increase the diameter
(obviously there is a limit there) or maybe 3 or even 4 blades? Would
the lower RPM have a significant effect on propeller efficiency?
After rereading my post I think I need to explain what I mean by "true
alternative" engine. Almost all of the engines talked about on the list
are basically the same thing we have been using for the past 50+ years.
Nothing of substance has changed. Sure there are now better alloys,
manufacturing processes, higher tolerances, and the odd minor refinement
here and there but it is still the same basic engine design.

Lead is used in fuel for lubrication purposes. It helps to lubricate the
valve guides and keep the valves from sticking. It is added at the fuel
farm when they brew the fuel. If you are going to use unleaded gasoline it
is recommended that you use a top end lubricant in the fuel to aid in
lubricating the valve train. Most people I know use Marvel mystery oil or
an additive that is available at FBO's that they place in their unleaded
fuel, prior to pumping it in your plane.

Axial compressors in a turbine use wing shaped blades to impart velocity
into the air molecules then the stators act like diverging ducts to convert
the velocity into pressure.
Centrifugal compressors are similar but they use certifugal force to impart
velocity rather than Bernoulli's principle, than a diverging duct for the
pressure rise.

Ahh... I looked at that one about 5 years ago and got really interested
in it. Talked to the designer a bit and it appears it's a real design
having originated within his Master's program. He told me they had a
few things yet to work out and they expected to license it for
production or maybe limit production to in house. Said heating had
been a problem they were working on still -- don't remember what else.
I can't think of a good reason this would not be a very valid AC engine
given a proper shakedown before production. At the time I talked to
them he was estimating about $25K, which seemed to me to not be a good
strategic price to attract the pioneers he would need to get it kicked
off right. Don't know if he ever made it into any real production or
not but assumed he probably did.
As for propellers, it should handle very large props, multiple blades
and heavy pitch very well. This engine has massive torque and really,
really likes to operate around 12-1500 rpm and is just pickled tink to
idle around 150 or so.
For some newer technology and a much better history of reliability and
cost/performance, I'd be much happier with modern rotary engines
myself. In fact, that's very likely what I'll use. JMHO...

No joy on the pictures, those were among the group of pictures that I lost due
to... ok stupidity long story. Sorry I couldn't help you out. When I take the

The only thing that Tetra Ethyl Lead every did was to enhance octane. The
rest is Baloney from the sales department. It fouls plugs, dirties oil,
sticks valves, erodes exhaust stacks. Lubricate, nonsense. IF it did,
valves would not stick.

I attended a forum at SWRFI last weekend on engine break-in put on by ECI
and in their test cell hangar. When asked about auto gas and lead, his short
answer was there was currently no substitute for lead because of the valve
temps we run. I'll probably butcher his explanation but he said the valves
and seats used specific metallurgy that created an oxide layer from the lead
that turned molten and provided thin film lubrication at the normal valve
temps we run. He said if you took a brand new engine and ran it only on auto
gas, it would destroy itself in short order. He recommended break-in on
avgas only. Then if you run unleaded auto gas to run avgas every 3-4 tanks
to restore and maintain the oxide layer. He was spouting science and test
results (ECI makes engine parts) so I'd judge him to be more credible than
Deakin and his mostly anecdotal evidence, at least as for valve lubrication
- octane is another matter. Your choice but remember it ain't fun when the
fan stops.

You wouldn't just increase pitch because you want to stay near the max L/D
for the blade airfoil. That means more blades, diameter, chord, airfoil or
other design change. A CS prop optimized for cruise at 2450 would probably
suffer at 2000 rpm trying to absorb the same horsepower. Just for reference,
my Navion's GO-480 prop is turning 1764 rpm at my cruise engine rpm of 2750.
It's turning a 93 inch 3-blade prop with 295hp.

And all along I thought "Ethyl" was a better grade of gasoline. In the '50's
it was an additional cost item that raised the price per gallon of gasoline
and then when the oil companies were forced to remove/eliminate same we were
told that leaving it out would again raise the price per gallon. Next we'll
be told that doing nothing will also increase the price per gallon. Huh...
That's what Gov. Davis is telling us in California. 8*) KABONG (GBA) Do

P.S. : I picked the '50's 'cause that's when I started buying gasoline, I
think Ethyl was about .23 a gallon in 1956 but then again at my age I.C.R.

Chris,
That's FINE! It's 01:01 then! So it's John Deakin's vs. Peterson Aviation's
statements.
Did you actually read the material on what I supplied you links for? Do you think
Peterson Aviation did their homework and therefore "sound very credible" to
you also (P.A. claims to have sold over 30,000 STC's based on their actual research
on AutoFuel)?
No offense man, but you know what you know, and whatever you know is just FINE
with me.
Can you explain to me the following Statement made by John Deakin in his report
under *Lead Myths* (I did read a quick few parts of it):
" . . . I do have one report that high-output marine engines had some valve problems
when switched from mogas to unleaded fuels, but that same report said that
hardened valve seats took care of that problem. . ."
That sounds like increased wear after dropping the lead that does not lubricate,
right?
Sincerely,
Konrad

The article that I read says that lead does not help in lubrication. I found

I didn't read the whole site but I did read the section on lead. And yes he does
sound credible but I didn't see him quote any studies or data that contradicted
what was said in the article on avweb. I'm not really trying to say that
one is right and the
other wrong, I am just trying to add fuel to fire, as it were, in an attempt to
see if anyone can produce more evidence one way or the other. I would like to
see more that is written on the subject.

Reply to number 5 is as follows which was picked up from the EAA web site:
The term 80/87 describes the ob-served
actual performances (resis tance
to detonation) when the engine is
operated with a lean condition (80-
octane) and then rich condition (87-
octane).
Automotive fuels are not rated in
this way but use an antiknock index
and an average of the research octane
method, and motor method.
The antiknock index posted on
autogas pumps is approximately five
points higher than the actual octane
rating of aviation fuelthus an an-tiknock
index of 87 posted on an
autogas pump would equate to about an
average 82-octane aviation fuel.
Autogas STCs for 80-octane aviation
engines require a minimum of 87-
antiknock index.

Dear CY,
I don't know nottin' (nor do I care to!) about the air-cooled VW's and their specific
failure modes at whatever mileages.
Unless the Beatle is airworthy and has a Lycoming in it, I'd say let's leave it
out of this Lycoming related Discussion.
Also, our two Mercedes' and the Subaru don't care much for 100LL, as they were
*DESIGNED* for unleaded fuel from the start.

That is what I was told by a retired Engineer that work for the Ethyl corp
during development and retired from Deere & Co. The lead may facilitate heat
transfer from the valve to the seat but lubricate? How? Sticks valves very
well.

How about inquiring directly with the engine manufacturer, i.e. TEXTRON LYCOMING,
to see WHY they specify whatever grade of leaded or unleaded gasoline for
their products? They should be able to give us a straight answer (at least its
a good guidance for warranty purposes down the road!)

I didn't read the whole site but I did read the section on lead. And yes he
does sound credible but I didn't see him quote any studies or data that contradicted
what was said in the article on avweb. I'm not really trying to say that
one is right and the
other wrong, I am just trying to add fuel to fire, as it were, in an attempt
to see if anyone can produce more evidence one way or the other. I would like
to see more that is written on the subject.

| Subject: | Reversity? NON RV |
--> RV-List message posted by: "Konrad Werner" <Connywerner@wans.net>
Dear Matt,
Sometimes I receive an answer to someone's question on the List's I subscribe to,
before I even get the original question??
I am not a PC-Guru, so I' thought I'll ask you how this works? NON RV RELATED and
do not archive.
(Could it possibly have to do with high speed / low speed connections of the individual
users, or what?)
Any insight would be appreciated, and do not archive.
Thanks,
Konrad

Dear Chris W. / Cy G., etc.,
Did you ever read this EAA Document in regards to the subject (...courtesy of Larry
in Indiana / Thanks Larry)
http://www.eaa.org/education/fuel/autogas_vs_avgas.pdf
See the bottom right corner (next to the pic of the DC-3) for a little insight
on lead's qualities in regards to Octane vs. Lubrication.
Don't stop there, but rather read the whole 4-Pages to make an educated decission
for yourself.
