Dana, I didn't notice any problems with your skins a couple of weeks ago.
Why do you ask? Did I create some? :-)

Guys:
I just want to say thank you for all your support. I am
thankfull that there are people who support our veterans and for those of
you who have responded personally to me, I want to give a heart felt thank
you to all of you. I have had mixed emotions about going over there to do
my duty. I may not have to go but if I do I will carry your thoughts with
me. I guess every soldier would like not to go to war, I am one of tose who
do not want to go. However If called to active duty I will go and do my
best to get back home in one piece. I will not dodge this responsibility if
called like some ex president we had. again to all of you, God bless and
thanks.
your friend

--> RV-List message posted by: "Frazier, Vincent A" <VFrazier@usi.edu>
I recently bought a chute for my Rocket from Paraphernalia. They will send you
a chute or two to try for size and comfort.
I ended up with a seat pack wedge. Not to be confused with either their seat pack
or their wedge, i.e.it was a seat pack packed in a wedge shape.
In the Rocket or the 4 there isn't any room to put the chute behind you. And most
seat packs are too tall. Very difficult to find a chute that will fit in
there. BTW, I'm 5'10" and 170#
The seat pack portion of my chute extends forward past the 404 bulkhead for thigh
support. I had my container customized with velcro on the butt portion so
I could add Temperfoam cushions as needed to tweak the fit.

| Subject: | Re: Drill Size??? |
--> RV-List message posted by: "DAVID REEL" <dreel@cox.net>
The right drill size to use depends on what goes in the hole. For example, a 3/16
drill is nominally .1875 inches in diameter. But AN3 bolts have some variance
in size between individual bolts, and usually increase in diameter a little
as you move up the shank and get close to the head. I have found that some
bolts will slip right into a 3/16 inch hole whereas some bind up. In the latter
case, using a #12 drill which is nominally .1890 inches in diameter, eliminates
the problem. So, Van's advice to drill all holes with a #12 makes sense
since it increases the chances that any bolt will go in any hole. Unless you
are using precision bolts, as are used in the wing spar, there is little benefit
to reaming standard bolt holes as the variation in bolt diameter defeats the
goal of achieving a close, and therefore long lived, fit. The kit is engineered
with standard construction practices in mind so there's no need to lengthen
build times by making beautiful holes. But, if you get pleasure from the
way a bolt slides into a precisely fitting hole with just a little friction telling
you the fit is fine, well then, enjoy.

I suggest you guys look at the FAA AC 43-4 about corrosion inspection.
1100 aluminum can corrode is when it is poorly covered, like in bad paint or
plastic coating.
Its called filliform corrosion and is caused by the fact that oxygen is semi
kept away from the aluminum so it can't form a uniform oxide barrier.
Therefore it continues to corrode under the paint/plastic.

Yes. Typically the engines will not be run for more than one or two hours at "the
factory" - which means the same break-in considerations still apply.

If you're serious about getting a real world IFR ticket that will give you the confidence to launch off into the weather on your own once you "graduate" then you need to check out the following link: http://www.ifrwest.com/
I completed this course in 1995 and it gave me the skills and confidence to take
my family into the soup in busy class C airspace with fast-talking controllers.
Morey's west coast IFR training course is unique among concentrated courses in
that it takes place on a long cross country trip starting from Middleton, WI,
heading to the pacific northwest, down the CA coast (thru San Francisco and SoCal
airspace), across the desert southwest, across the Rockies and finally back
across the bread basket to WI. Morey takes two students in a turbo C182RG complete
with every bell and whistle imaginable (HSI, TCAS, Stormscope), Garmin
530, autopiolot, etc. etc.). Morey has 30,000 hours and is a designated examinar
so your last three legs of the trip home are your checkride (Morey's father
was a pioneer in WI aviation history. His pilot certificate was signed by Orville
Wright). This course has been written up in AOPA Pilot and other aviation
periodicals.
You need 20 hours of actual or hood time to enroll and need to know the basics
of shooting approaches. To start you spend three full days in WI getting checked
out in the plane, flying a Frasca simulator, shooting a significant number
of approaches, and lots of time in ground school. Then you are off for the one
week cross country. Each student does 50% of the flying. You get as much
actual as the weather allows. Much of the actual is flown partial panel. When
you are in the clear, it's all hood time with full panel.
The greatest thing about this trip is the wealth of experience that Morey has as
well as the chance to fly in a new environment for every approach.
Morey even has a graduate course now that goes to Alaska. You need your IFR ticket
to even sign up for that one.
Morey gets a significant number of "repeat offenders" that use his course as a
refresher or a proficiency check. Most of his students come from around the country,
not just Wisconsin.
Contact me offline if you'd like any more of a testimonial.

| Subject: | multiple terminal boots, same terminal |
--> RV-List message posted by: "Dan Checkoway" <dan@rvproject.com>
I'm wiring my engine ground strap to the firewall, and I'm bumping into
something that has come up a couple of times so far...two or more wires
going to the same terminal, and a conflict when you try to use terminal
boots/nipples on all of the wire ends.
I'm sure it's something very simple I'm missing, but what's the trick for
getting multiple ring terminals protected when they're on the same terminal?
Do most people just protect the "top" terminal?
I may not even bother with a terminal boot here, since these are ground
wires anyway...but in some cases there are hot (positive) terminals that I
do want to protect, and I've been settling for kind of kludgy fits of
terminal boots.
Any tricks?
Thanks in advance,

I have been on this list just about a year now, (didn't know it existed
before--sure could have used it during building my 6-A) and I have read many
posts during that time asking advice which was well covered in the builders
manual THEN! Makes me wonder if manuals issued since mine (before 1995) have
the same info.The cut and paste below is an example:

In my manual, Section 15,--PREPARATION AND INSPECTION OF THE
ENGINE.---there is a note, quote:
"---A serious engine break-in problem faces some amateur builders for which
there is little guidance. For example, a newly overhauled engine with
chromed cylinders, or a new engine, must be broken in properly. That is, the
engine needs to be operate at high RPM and the temperatures kept low* or the
piston rings will never seat Unfortunately, this means that the engine
temperatures during initial ground operation will be critical and often the
engine operations must be severely limited. This usually precludes prolonged
taxi testing and high speed taxi tests------"
*(This should read "high". See following paragraph.---H):
"---When engine break-in is a concern, perform flight testing without the
wheel fairings and gear leg fairings. This will add around 15% to the
airframe drag and cause higher engine temperatures at any given forward
speed.----" --Unquote.
So my question is: Do the later or newer manuals cover the above and if
so,-- are builders neglecting to READ THEIR MANUALS!!
Cheers!! ----Henry Hore

| Subject: | Really Nice Comments... |
--> RV-List message posted by: Matt Dralle <dralle@matronics.com>
Dear Listers,
We're nearing the end of this year's List Fund Raiser and I wanted to share
some of the really nice comments members have been making about the Lists
and what the Lists mean to them. Please take a moment to read over some of
the thought's members have shared with me in the last couple of weeks
regarding the Lists. Its pretty awesome.
If you haven't taken a moment to show your support for the operation and
upgrade of these services, won't you do so now? These Lists are operated
solely through the $20 or $30 contribution you make each year. Without
your yearly support, the Lists may cease to exist in the future. It takes
your resources to keep these systems up. Remember, there's no advertising
budget to keep things afloat. I think pretty much everyone appreciates the
fact that I don't have any pop-ads or flashing banners of any kind on the
List. Your support assures it will stay that way.
Please make your contribution today and, in one small, way fight off the
every increasing commercialism creep that is taking over the Internet!! :-)
The SSL Secure web site for making your List Contribution can be found here:
http://www.matronics.com/contribution
Thank you to everyone that has already showed their support for the List!!

And then there is intergranular corrosion. Sometime this cant even be seen until
the damage is done.

Yeah, and then there is "just ignore it" corrosion, sometimes initiated
by bird droppings, not wiping off "love bugs" or flying too low over
salt water (I never did that, tho)--sometimes the corrosion is related
to how flat the tires are or how much accumulated dust/dirt is on the
canopy/windscreen.
I guess I'll have to move my electron microscope out to the hangar to
figure it out.
