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!

Many thanks to all of you for your help.=0AI=B4m clear now, NO FLAPS..... R
ight now I fisnished the vertical tail and elevator, all the ribs done and
planning to begin with the spars.=0AIt sounds great the speeds you mentione

List: CH601HD flaps=0A =0A=0AMarcos,=0AI have a Jabiru 3300, no wheel pants
and built per plans except I=0A added the forward tilt canopy.- If
you stiffen the baggage locker=0A doors (check the list archives) and
add extra Dzus fasteners (I=0A have a total of 8) then there is no mov
ement in flight.- With the=0A 3300 there is definitely no nose high
attitude.- Most people are=0A finding the need for slight nose up tr
im or slight adjustment of=0A the horizontal stab.- but it is a weig
ht and balance issue only.-=0A Move the battery fore or aft to get t
he W&B in the center then=0A no problem.- I have leading edge fuel t
anks with 15 gallons in=0A each plus an 8 gallon header tank.- With
a fixed pitch Sensenich=0A prop I fly at an indicated of 105-110 mph a
t 2700 to 2750 RPM, at=0A a fuel burn of about 5.5 gal/hr.- If I inc
rease RPM to 2800 I get=0A about 115 MPH but fuel burn goes up to 6 -
6.5 gal/hr.. At 2650=0A the fuel burn goes below 5 gal/hr and the crui
se is about=0A 99-100mph.- I still say no flaps needed for the HD.
- If I pull=0A power and set for 60-65 indicated I can land in less
than 700 feet=0A with little braking.- The descent angle is quite st
eep. I normally=0A do final at 70-75 and slow to 65 over the fence and
still land in=0A less than 1000 feet.- Good luck it's a fine plane.

o Jerry, thanks a lot for your info. I=B4m a begginner with only about 50 h
ours of flight.=0A>I flew about 40 hours on a Tecnam P92 to get my Permit t
o Fly=0A and about 15 hours on my homebuilt Minimax. I have no probl
ems=0A with my Minimax as it land at about 40km/h and like you said,
=0A just cutt off engine to iddle and down...But with P92 you need
=0A to approach very high to avoid the trees (there are always=0A
turbulences up there) and after, you eat a lot of the runway=0A
even with flaps. I compared it because the approach speed is=0A sim
ilar to CH601HD. Another reason is the nose up attitude that=0A let
the flaps. I flew 4 hours for practice on a Zephyr 2000=0A (faster a
irplane) and you need almost the entire track......=0A>I have an Jabiru 220
0 engine for it, that=B4s the reason I choose=0A the 601HD instead o
f the XL.=0A>Just some more questions, I read a lot on the net about this
=0A airplane but:=0A>-What=B4s the real cruise speed?=0A>- Is true t
hat in flight normally takes a nose high attitude?=0A>- Is true that baggag

r your comments and sorry for my poor english..=0A>My Best Regards=0A>Marco
