Smitty,
I can try e-mailing it. Either zipped or not. You might also try the
suggestions by Fred of right clicking and Saving Link (or Target) as a pdf
file. That has worked for me before on large pdf files that I otherwise had
trouble viewing in a web browser.

Hi all,
I have a Garmin GNS 480 (formerly CNX 80 of UPSAT) install kit I'm trying to
get rid of. It was wired by Stark Avionics (the famous 'John Stark') and is
ready to be installed in your panel during construction. The 'black box' can
be slid into the tray at a later date when needed and money is available.
Make offer, anything considered! Please respond directly.

I just spoke to Tom at Van's and he claims that changing one of the
aileron rod lengths should have no impact on a heavy wing. He is also
negative on compensating for a heavy wing by lowering one of the flaps.
His only suggestion for the nine, is to figure out what is out of rig
and fixing it, or putting a wedge under the aileron of the opposite
wing. His plane is out of rig so he has an aileron wedge, and he
decreases fuel for takeoff in one wing when flying a passenger.

No, I meant 'flap' (singular, as in one-side only).

To say that trimming a flap would have no bearing on a wing-low condition
is silly IMHO. The flap is aerodynamically similar to a huge aileron,
aside from being further inboard. A tiny amount of differential adjustment
makes a noticeble correction. It has worked fine for me and those who
recommended it to me. I don't have any way to verify the original source,
but I was told the advice came from Vans and that it is a common tweek. I
can say with 100% confidence that it worked like a charm for me! It's
likely that many cases of "heavy wing" (assuming the scales don't back it
up) are really nothing more than a minor rigging issue with flaps or
ailerons. When you watch your ailerons in flight, you come to realize what
a huge effect a tiny movement has.

Several comments about the fix for a heavy wing on a RV9 have been posted. Ailerons
fly in trail, Flaps are fixed. As suggested, adjusting the length of the
aileron actuators will provide neutral effect.
The fix for a heavy wing on RV6 etc was to pinch the trailing edge of one of the
ailerons, I don't remember whether to pinch the heavy or light aileron.
Finding the "out of rig" element can be problematic given the muriad of places:
Wing tips, flaps, wing incidence, to name few. It would be particularly difficult
when looking for a measuremnt of 1/20" or less.
For discussion sake, lets say that I found one flap to 1/20" out of true and corrected
it. I find it less offensive to do that than to "scab" a triangle shim
on to the bottom of the light aileron. It is difficult to know the tone the
Tom was using when he gave his answer, but why did he not find the offending
out of rig element and correct that?

John, to a first approximation, changing the length of one of the flap
push rods should not have made any difference to a heavy wing since the
flaps fly in trail. However this will change the neutral position of the
control stick. A difference in position of the control stick will change
wing balance since the aileron trim will now be pulling one way or the
other.
My heavy wing required a short wedge under the "light" aileron. There
was not enough adjustment in the aileron trim to compensate for a
passenger and a fuel loading imbalance.

I experienced a slightly heavy wing on the
first flight which I was able to trim out until landing for final adjustments.
1 turn in on the opposite flap push rod (1/20") has it flying straight.

..of course, RV-9's have 'unpinchable' trailing edges built up from wedge
rather than rolled like the 6's. I agree, it doesn't take much!

--> RV9-List message posted by: Matt Dralle <dralle@matronics.com>
Dear Listers,
I'm very proud to announce a completely new BBS interface is now available for
all of the Email Lists at Matronics! This is a full-featured system that allows
for viewing, posting, attachments, polls - the works.
But the best part is that it is *completely* integrated with all of the existing
email tools currently available at Matronics! What this means at the most basic
level is that, if you post a message to List from Email in the traditional
way, it will show up on the BBS system *and* get distributed to everyone currently
subscribed to the Email List. By the same token, if you are on the BBS
and post a message to a given List-Forum, the message will not only show up on
the BBS, but also be distributed to everyone on the Email List!!
It is really a very nice implementation and I am very pleased with its operation.
All of the tools you have come to know and love such as the List Search Engine
and List Browse and Download will still be available and contain all of the
latest posts. Think of the new BBS interface as just another method of accessing
the all of the Lists.
You can use the BBS to view all of the latest posts without having to do anything
except use your browser to surf over to the site. You can view and look at
all of the various List's posts. If you want to post a new message or reply
to an existing message from the BBS, you will have to Register on the BBS. This
is a *very* simple process and will only take a couple of minutes. There is
a small icon in the upper righthand side of the main BBS page labeled "Register"
to get you started.
I strongly recommend that you use the exact *same* email address you are subscribed
to the Email Lists with when registering on the BBS. Also, while not an
absolute requirement, I would really appreciate it if people would use their full
name when choosing their Username on the BBS (for example "Matt Dralle").
This just makes it easier for everyone to know who's posting. Also, I have enabled
the ability to upload a small user picture with your profile called an
"avatar". Please use a *real* picture of yourself *with* your cloths on! Thank
you! Maximum size of the bitmap is 120x120.
You can either be subscribed to the BBS, or any number of Email Lists, or both.
Registering on the BBS will allow you to email directly to all of the various
Lists. However, to receive direct List Email, you will need to be *subscribed*
to the various Lists as you have in the past. No changes here in operation.
I have added numerous links on the BBS pointing to the Email List subscription
page.
I've had the BBS connected to the Lists for about a week now, so its already loaded
up with a fair number of messages. You can post photos and other documents
directly to the BBS and links to them will appear in the List Email distributions.
Also, when any messages posted to the BBS are viewed in the List Email
distribution, there will be a URL link at the bottom of the message pointing
back to the BBS.
And here's what you've been waiting for -- the main URL for the new Matronics Email
List BBS is:
http://forums.matronics.com
Please surf on over, Register, and have a great time! I think this will be the
dawn of a whole new era for the Lists at Matronics!
Best regards,
Matt Dralle
