Over a glider no-less!
For people who have done that, is there a difference between a stopped prop and
just at idle you think?

Absolutely. A windmilling prop creates more drag. Next best thing is a
feathered prop. Next best thing is an engine developing power :-D .

Does anyone have a picture of a 'powered' rudder trim for an RV-10 install?
I'd like to take a look at how folks did it while I'm working on the rudder.
Thanks....

| Subject: | 51% Rule Interpretation |
Have you written you letter yet? Don't procrastinate any longer. Here
is my contribution for whatever it is worth.
I am very concerned that the rule interpretation proposed by the FAA
will create a bureaucratic obfuscation of the 51 percent rule to the
extent that it will discourage many potential builders and inhibit
technological developments of current and future builders. To establish
a clear delineation between fabrication and assembly is impossible. To
force such a distinction will result in builders following much more
conservative practices to insure that their aircraft will meet the 51
percent rule thus eliminating much of the dynamic development that has
been a hallmark of the experimental world. This would be a great loss
to the aviation industry.
Requiring each task in building an aircraft to be designated as either
fabrication or assembly would require extensive documentation of these
tasks creating a mountain of paperwork which at best could only be given
a cursory review by the FAA. Creative people are not known to have the
inclination or the time to spend on documentation. Thus this
interpretation would likely drive some very bright people into other
avenues of development than aviation.
If the FAA is concerned about cheating on the 51 percent rule, it should
tighten up enforcement of the existing rule. It has worked well for 55
years. If there is a problem now, update the enforcement, not the rule
that has served us well for so long.
I am an A & P who has not practiced since 1965 due to a change in my
career plans. I have recently retired and am in the process of building
an RV-10. It will be a fine airplane and I will certainly put in more
than 51 percent of the effort to make this aircraft airworthy. The
project is an excellent refresher and I am updating my knowledge of
aircraft construction and equipment; e.g. we did not use fiberglass in
the early '60s.
There were 20 RV-10s lined up at AirVenture this year. While the RV-10
is a recent, standard kit, no two of the RV-10s were the same. Each was
altered to meet the needs and dreams of the builder(s). Some
alterations were minor and some were major, but all demonstrated the
spirit of experimental in aviation.
Sincerely,
David J. Fritzsche

| Subject: | Fwd: Bill O'Brien |
Just got an e-mail from AMT Online, in it was this attachment. Any of
you that are IA's have undoubtebly heard of him, some of you may know
him.
Prayers for Bill
AMTA
I am writing to you all to inform you of some sad news and I would
like to ask for your assistance. I have been told that Bill O'Brien is
in the hospital and he is in very bad shape. Many of you know Bill and
what he has done for our craft. For those of you who do not know Bill
let me just say that he is certainly one of a kind. Bill recently
retired from the FAA after a long career of championing the AMT craft
& profession. His accomplishments are many and Bill would be the first
person to down play his importance because that is Bill's style. He
never did anything for selfish reasons. His ultimate goal was helping
the AMT. One of the things that Bill did was create the FAA's Charles
E. Taylor Master Mechanic Award which recognized AMTs having FIFTY
YEARS of working experience, with 30 of those years being licensed.
This is a very prestigious award that recognizes those men and women
who helped shape our craft into what it is today. Without Bill's
energy there would be no such award.
Bill also worked with Eastern New Mexico University to not only
recognize that the A&P license is worth 72 credits towards a college
degree but also helped ENMU create the four courses necessary for a
licensed AMT to take in order to earn an Associates Degree. It is
because of this that I am going back to school, as are many others, to
finish my education. Bill also advocates AMTs to earn their I.A.
certificate because AMTs should be as knowledgeable as possible. He
has also written a wonderful monthly article in AMT Magazine
addressing issues concerning AMTs with an informative, direct and
humorous approach.
These are just some of the many positive impacts that Bill has had on
our craft. Bill is a mechanic's mechanic. He needs our prayers and I
would like to ask each of you to do just that. The Lord listens and if
we all talk to Him, wishing for a speedy recovery for Bill, I am sure
that Bill will be back doing what he has always done... fight for
AMTs. Cards can be sent to Mr. Bill O'Brien, 12508 Lt. Nichols Road,
Fairfax, VA 22033. Even if you have not heard of Bill he would be
happy to receive a card from you. With all that Bill has accomplished
if it was measured in the number of get well cards the USPS would have
dedicated trucks just for him. Please tell your fellow AMTs about
Bill's need for prayers and words of love and well wishes. Sincerely,
Kenneth MacTiernan Director AMTA

| Subject: | Air compressor tripping circuit breaker |
Hey Deems,
I apologize for not getting around to this earlier. It's been a busy
week.
Another idea is plugging it into a fairly hefty computer UPS. I will
bet that it will buffer the current draw during the startup and reduce
the draw on the circuit.
It's just another idea to consider. It would be a really easy and big
startup capacitor.
I apologize if this possible solution was provided earlier.
Just a thought.
Phil

Well, Thanks to all for the suggestions. I made a trip to the hangar
this am. Jason, I found the compressor is equipped with all of the
features you mentioned (bleed valve & capacitors), I removed the belt
guard, and checked tension which appears 'normal' (?) then removed the
old (black) oil and replaced it with new compressor oil from Lowes, gave
it several turns of the flywheel manually to lubricate the cyls then
plugged it in directly to the outlet vs the extension cord and.........
Viola! it worked!!!!! no tripped circuit ?!?!? I should mention that
there were no other folks out in the adjacent hangars today. I checked
with airport nazis ops about the possibility of changing/modifying the
service........ I think they are still laughing, glad I could make their
day. They told me that there were up to 3 other hangars on the same
circuit, so who knows how long this will work, but it should suffice for
the intermittent needs for final assembly and maint at the hangar

Robin,
Your rudder trim is the cleanest to date short of some of the knob and scre
w systems, how about a little info on the modifications you did such as rei
nforcement of the trailing edge, additional ribs inside the rudder...anythi
ng you can think of that would make this easier for us to duplicate..right
now I'm fixin to do the hinge method but some details of your design would
be great...I get the tray setup and the servo but what did you do internall
y to preserve the trailing edge integrity=C2-above and below the tab? I r
eally want to go this way, the only thing I may do different is a composite
tab instead of the aluminum one...and yes I have stared at your pictures f
or at least a year or ever since you posted them...just getting ready to ge
t off the pot and cross this one off my list of TODO's but a bunch of newbi
es to the list will start asking this question, which one just did, hence m
y request...So how bout a little writeup. Only address the stuff that is no
t obvious in your photos unless you're feeling expressive!!=C2- :)

Very cool, I just bought a new GE washer and dryer today...Does that mean I contribute
to the cause??? You can almost smell the grass and smoke oil watching
