| Subject: | List Fund Raiser |
A couple of years ago I implemented an automatic "squelch button" of sorts for
the Fund Raiser messages. Here's how it works... As soon as a List member makes
a
Contribution through the Matronics Fund Raiser web site, he or she will instantly
cease to receive these Fund Raiser messages for the rest of the month! Its
just that simple. Don't you wish PBS worked that way! :-)
I really do appreciate each and every one of your individual Contributions to support
the Lists. It is your support that enables me to upgrade the hardware
and
software that are required to run a List Site like this. It also goes to pay for
the commercial-grade Internet connection and to pay the huge electric bill
to
keep the computer gear running and the air conditioner powered on. I run all of
the Matronics Email List and Forums sites here locally which allows me to
control and monitor every aspect of the system for the utmost in reliably and performance.
Your personal Contribution matters because, when combined with other Listers such
as yourself, it pays the bills to keep this site up and running. I accept
exactly ZERO advertising dollars for the Matronics Lists sites. I can't stand
the pop-up ads and all other commercials that are so prevalent on the Internet
these days and I particularly don't want to have it on my Email List sites.
If you appreciate the ad-free, grass-roots, down-home feel of the Matronics Email
Lists, please make a Contribution to keep it that way!!

Degreasing is the most important step. An industrial detergent, not
dish soap.
Second, a scuffing with either 400 paper or scotchbrite pad.
Third, a light coat with rustoleum automotive spray can primer will do.
Never let any primer sit and get hard for more than a few days or you
will have to at least re-scuff it.
BB, MkIII, no peels, no flakes.

... but it IS airplane related. Found on another list, some spectacular
photos from Alaska. Sadly the pilot/photographer, Shaun Lunt, is no longer
with us after a low altitude stall/spin earlier this year.

Hi Grant,
Thats great news on your 503, your performance numbers are impressive for a MK
III with that engine, being light makes a much bigger difference in Kolbs than
I would have ever thought. I am surprised to see that you are flying with 20
pounds of ballast when alone, I weigh the same as you do and have never used
ballast, but my empty weight is about 650 pounds empty, the 912-S is heavy and
changes the way weight and balance works out quite a bit... I adjusted my elevator
trim with fixed aerodynamic tabs so that my Kolb flys straight and level
with me alone using no spring trim. I add spring trim in depending on the
weight of the passenger, I have carried a 220 pound passenger and still have
some trim range to spare.
One other thing that surprised me about the Kolb was how much flap rigging can
affect roll trim, use great care to get each flap at exactly at the same angle
to keep them from inducing a roll. In the end, I used a digital level to rig
the flaps perfectly level with each other and used Kolbs adjustable Rear attachment
brackets to adjust each wing at exactly same angle in relation to the fuselage.
This resulted in a my airplane flying level with no trim tabs needed
on the ailerons, I have trim tabs on my ailerons but they are neutral... My
Kolb flys straight hands off and stays level in a stall. I am not home now, but
I will post some pictures I took of the adjustable brackets from Kolb when
I get back. I also have some cool videos I will edit and post as soon as I am
get to my computer.
