WELCOME!
Tales
from the DAR Side
I'm amazed that an entire year has gone by
since I wrote my first column for Experimenter,
yet here we are celebrating its first
anniversary. Putting Experimenter together is
fun, but it's also a significant undertaking.
The fact that the newsletter has been so well
received by the homebuilder community is both
satisfying and invigorating. Our goal is for you
to continue to enjoy Experimenter as we go
forward, and we hope you'll spread the word to
other homebuilders who may not yet be enjoying
the newsletter, EAA members or not. Read

Paul's
Pick
EAA
is not only an organization of builders, flyers,
and enthusiasts; it's a voice for the aviation
community when policy is being made in
Washington, D.C. While EAA works hard to study
current and upcoming policies and regulations,
Paul Poberezny wrote in his column from the
March 1973 issue of EAA Sport Aviation
that members may want to be proactive about
policy changes in the works instead of being
reactive after they are enacted. Paul also
suggested that buyers beware and understand how
aircraft are licensed in the experimental
category and how they can be used before making
a purchase. Read

Looking
at the Facetmobile From a New Angle
As
I get older I have learned to count my
blessings. One of those blessings is our
abilities as EAAers to walk amongst the giants
in aerospace and talk airplanes, their design,
or to just share a laugh. When we meet these
fellow EAAers, they are our Wayne Gretzky, and
what they share with us is often akin to getting
stick handling lessons from Gretzky himself. Read

From
Odd to Awesome
This
Aerosport Quail fits the bill
Being
exposed to homebuilding and experimental
amateur-built aircraft at an early age, I could
consider myself to have a leg up in my knowledge
of various types of light-experimental
airplanes. So it would stand to reason that when
the time came for me to actually consider
finding or building a plane I could call my own,
I could almost say that I already knew just what
I wanted. Read

Turbines!
Is it turbine time for homebuilts?
In
the upper power regimes of commercial and
military aircraft, the gas turbine variants have
taken over. Does this mean that turbine power is
ready to dominate the amateur builder field as
well? Although thirstier than piston
equivalents, the lower initial cost and light
weight are major selling points. However, in the
200 to 300 hp region, where most of the builders
live, the picture is not nearly so rosy; the
road appears littered with snake-oil salesmen.

How
to...
Connecting
Rod Balancing
I
recently received a letter from an Experimenter
reader seeking advice on “blueprinting” his
VW engine conversion. Put in the simplest of
terms, blueprinting is the same as “zero
timing” an engine, paying close attention to
the specific tolerances prescribed by the
manufacturer. To help achieve this you must
balance your engine components as I did with my
connecting rods. Read

EAA
Homebuilt Aircraft Council Seeks New Member
The EAA Homebuilt Aircraft Council's (HAC)
mission is to ensure EAA's continued focus on
programs of benefit to current and future
homebuilders. This council of EAA volunteer
leaders represents the homebuilder and provides
a conduit for information between EAA
headquarters staff and the homebuilder/craftsman
community within EAA.
The
HAC is looking for an experienced homebuilder
who has a background in marketing and public
relations. If that's you and you would like to
serve on the HAC, please send your résumé to hac@eaa.org.

EAA
Survey of Zenith Owners Published
Between November 25-30, EAA surveyed Zenith 601
XL and 650 owners to gauge their awareness of
the special airworthiness information bulletin (SAIB)
issued by the FAA, their awareness of the
service directive/safety alert issued by AMD,
and their intent to comply with both. EAA
identified 165 owners of the 601 XL or the 650
within its database and sent survey invitations
by e-mail. Read

One
year down and many more to go
What do you think of the new EAA
Sport Aviation? Contrary to the rumors, Sport
Aviation is alive and well as a print
magazine, but it is offered in digital form as
well. Click
here to see it. But before you go there,
read this message
from Adam Smith; it will help you understand
what EAA is trying to accomplish.
My
answer to that question is that I'm pleasantly
surprised. When I heard there was going to be a
change I cringed; I'm old enough to be
considered one of those who is "set in his
ways" and old enough to know that change
usually isn't for the best. When I heard that
the changes were going to include more general
aviation (GA) stuff, I wretched. But now that I
have the issue in my hands and have read
virtually every article (and ads), I've done a
180; I feel that the publishing staff and all
those involved in shaping this new product have
hit the mark. Is it perfect? Nope. It needs
improvement and will get it. Is it
"better" than past issues? Absolutely.
Am I blowing smoke up your skirt because I'm on
the EAA dole? No way. I honestly believe that
this is a huge move in the right direction and
an improvement over the past two decades of Sport
Aviation.
To
see what people are saying and to add your
comments and analytical review of the
publication, check out the forum
on Oshkosh365. Not a member and can't log on to
365? Then please send your comments to feedback@eaa.org.
The
thing that impressed me the most is the
seemingly exhaustive (by comparison) amount of
homebuilder info, especially from a hands-on
perspective. And the hands-on stuff that is not
specifically aimed at the homebuilder translates
well. Expect this to be the same in all future
issues; it's not a fluke. The GA stuff works
well too, as in addition to being builders we're
GA pilots as well.
Expect
also to see a closer tie between Experimenter
and Sport Aviation as time goes on. And
if light-sport aviation (LSA) or ultralights are
more to your liking, be sure to subscribe to the
new EAA e-newsletter, Light Plane World
which, like Experimenter, is meant to be
an extension of Sport Aviation. A full
list of all e-newsletters and the link to
subscribe to them are listed
here. We will certainly continue to do our
best to feature homebuilt LSA and ultralight
aircraft in future editions of Experimenter,
but if you are after factory-built LSA info,
this is not the place for that, Light Plane
World is.
We
continue to need your submissions and always
welcome your comments and opinions. Feel free to
contact me directly or leave your contact info
with your comments in our monthly survey if
you'd like to hear back.
I
have truly enjoyed bringing Experimenter
to you the past year and certainly look forward
to years of continued success, with your help.

Sport
Aviation, October 1994
The Facetmobile
Sport
Aviation had this to say about the
Facetmobile after it showed up at EAA Oshkosh
1994 and promptly won the Dead Grass Award.
"The
Facetmobile is, in fact, a research prototype
for a family of personal airplanes intended for
the real world private pilot. . .the person who
flies only 30 or 40 hours per year, basically
for fun, and who rarely ventures out more than
two or three hundred miles."

Q&A
Got a
question? Send it to us at Experimenter@eaa.org.
Whether you're building, restoring, or just an
enthusiast. we want to know what has you
stumped.
Q. I
am considering homebuilt aircraft with an eye
toward building or buying something that meets
the light-sport aircraft (LSA) definition so
that I can fly it as a sport pilot. How do I
know if the aircraft I'm looking at will
qualify?
A. This
is actually a complicated question. Homebuilt
aircraft are so individualized that no two
examples of the same design are the same, and in
many cases one particular aircraft may meet the
LSA definition while another seemingly identical
example won't. This being the case, a person
planning to buy an already-flying homebuilt
needs to be very familiar with the LSA
definition and very diligent in studying the
aircraft records to make sure the prospective
purchase indeed meets the requirements. Read

Glossary
Confused
by a strange aeronautical term? EAA's online
Aviation Glossary can help.
BRAYTON
CYCLE - A thermodynamic cycle consisting of
two constant-pressure processes interspersed with
two constant-entropy processes. Also known as
complete-expansion Diesel cycle, or Joule cycle.
It is named after George Brayton (1830–1892),
the American engineer who developed it, although
it was originally proposed and patented by
Englishman John Barber in 1791.

For
aircraft buffs, this is a keeper. It's an

the world: old, new, military, civilian. Browse
this site for a few minutes. You will be
amazed at what has been accomplished in airplane
design.
