Subject: | Who is Matt Dralle & What Are The Lists? |
Dear Listers,
Who is Matt Dralle and what exactly are these Lists anyway? I've been working
in the Information Technology industry for over 28 years, primarily in computer
networking design and implementation and more recently as an embedded software
engineer. I have also done a fair amount of work in web design and development.
I started the Matronics Email Lists way back in 1990 shortly after I started building
my RV-4 with about 30 fellow RV builders from around the world. Since
that time, I have added many other types of aircraft related Lists to the line
up and numerous other List related services such as the Forums, Wiki, Archives
and Search Engine just to name a few.
For flexibility and reliability, I have chosen to run all of my own servers locally.
Other List-related systems include a 1 Gigabit, fully switched network
infrastructure, a commercial-grade Netscreen firewall, a Barracuda spam filter,
a local T1 Internet router, and a bonded dual T1 commercial-grade business Internet
connection with full static addressing.
The computer servers include a dual quad-core Linux server for List web services
with 24GB of memory, a quad -core Linux system dedicated to the email processing
List functions, and another standalone Linux system serving as a remote storage
disk farm for the archives, databases, and for an on-line hard drive-based
backup system with multi-terra byts of online storage. This entire system
is protected by three large, commercial-grade uninterrupted power supply systems
(UPS) that assure the Lists are available even during a local power outage!
Speaking of power, imagine how much electricity it takes to run all of these
systems. On the average, the elctric bill is in the neighborhood of $7000-$8000/yr
and the newly upgraded dual-T1 Internet connection runs roughly $6000/yr.
A while back, I upgraded all of the computer racking infrastructure including new
power feeds and dedicated air conditioning for the room that serves as the
Computer Center for the Matronics Email Lists and followed that upgrade up with
a second rack upgrade to house the MONSTER web system that didn't quite fit
into the first rack! Here's a composite photo of the List Computer Center prior
to the addition of the second rack:

As you can see, I take running these Lists very seriously and I am dedicated to
providing an always-on, 24x7x365 experience for each and every Lister.
But building and running this system isn't cheap. As I've mentioned many times
before, I don't use commercial advertisments to support any of these systems.
It is supported 100% through List member Contributions! That means you...
and you... and YOU!
To that end, I hold a List Fund Raiser each November and ask that members make
a Contribution to support the continued operation and upgrade of this ever-expanding
system. Its solely YOUR Contributions that keeps it running!
Please make a Contribution today to support these Lists!

Europaphiles,
=C2-
Yesterday was a breakthrough day for myself and our Jabiru powered Europa Mo
nowheel Classic kit #A012. =C2-After making some changes in the cowl my CH
T issues have improved greatly enough for me to take the aircraft and to fin
ally experience what can only be described as a delightful flying machine.
=C2-I flew for 1.2 hours and took our "Gladys" (In honour of my English Gr
andmother) up to 5000 feet to get more familiar with the handling characteri
stics of the aircraft. =C2-I am pleased to report that I was able to trim
the aircraft =C2-and fly hands off and the airplane flew like she was on a
rail!
=C2-
In a best rate climb from 4000' to 5000' =C2-she climbed at 1600 fpm. =C2
-I also saw 126 knots indicated 123 ground at 2750 RPM burning 6.2 gallons
an hour. =C2-Control forces are balanced and responsive. =C2-Slow fligh
t, S-turns, turns around a point all very predictable. =C2-My landings are
getting better and i'll leave it at that...
=C2-
Pulling the cowls today and going to give the aircraft a real close inspecti
on and hopefully the weather and winds allow me to get up this weekend.
=C2-
Cheers,
=C2-

Subject: | Re: heavy left wing |
Something to check for with your "heavy wing problem". I had a similar problem
with my plane following a major wing repair, not my Europa but my Citabria.
It sure seemed that one wing had notably more lift than the other. The incidence
was equal wing to wing with no visible or measurable difference between wings
but it would not fly straight without input pressure on stick and rudder,
it wanted to roll. Because it seemed to be a wing problem, I proceeded to adjust
the washout/washin to correct the difference in lift, this can be done with
a high wing by adjusting the struts. I could get it to fly hand off but then
one aileron was 1 inch up and the other down. Needless to say, I sure didn't
like the stall characteristics with unequal washout. Scratching my head and
deciding to look outside my box, the problem turned out to be a misinstalled
tail wheel spring inputting rudder pressure to one side. This was not an intuitive
place to look for me but it sure was the problem. Correcting the spring
and rudder, it was then easy to get the plane tuned up and flying hands off straight
and level. So you might check if your rudder linkage is inputting pressure
to one side.

about 1 to 1 1/2 inches is straight and level flight. The right is up about
1/4 to 1/2" . I had been thinking since I weight in at 250 pounds that was the
cause, but today I added 150 pounds to the PAX seat, Sand Bags!. It helped,
but not my much.

Subject: | Across UK Stanstead zone |
I used to frequently get permission to route across Luton, London City and even
Heathrow (Ascott - Burnham) zones but haven't tried since the Olympics. Has anyone
had a route across any of these or Stanstead (say NW to SE) recently?
