| 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:
http://www.matronics.com/MattDralle-ListComputerCenter.jpg
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!

That's a good idea, that I'm going to copy, so would you be so kind to post
or send me the electric schematic you adopted to install that "Activate
Co-Pilot's Grip" switch.
Thanks

Bob, I chose to provide full functionality to the co-pilots stick but I also
have a Activate Co-Pilots Grip switch on my panel. The co-pilots stick
functions (Trim/PTT/Flip-flop/AP-Off/Flaps) are all inactive unless the
panel switch arms the co-pilot controls.
I did the same for the 8A which was a mistake. Just too complicated for the
few times they may be desired.

"Safety Trim" is a commercial product. As stated above, it is an electronic
control box which will not allow the trim to run for more than 3 seconds at
one button push, to guard against a runaway trim situation. This could be
due to a stuck top hat switch, or some have reported a passenger leaning on
the right stick trim switch. (For this reason I opted not to install a pitch
trim switch on the right yoke.) This is more critical for pitch trim, which
is much stronger than the spring loaded aileron trim. I don't know anyone
who has the Safety Trim box powering their aileron trim.

It seems you have a similar solution as Robin's, but it can be different, so
would you post or send me your electric schematic on this "Pilot / Co-pilot
control switch" you installed.
Thanks

Safety Trim is used as a replacement for relays and such. I have the trim
top hat on the control stick going to the Safety Trim box, then from the box
to the aileron and elevator trim servos.
On the "co-pilot messing with the trim top hat on his/her stick" problem, I
added a Trim/Flap control switch on the panel. It has a Pilot and Co-Pilot
position. This way the co-pilot cannot inadvertently operate the trim or
flap switches on co-pilot stick unless selected. It has a side benefit of
isolating the pilot stick switches if one fails and allowing trim/flap
operation from the other stick as a backup.

trim)
Assuming you are using something like the Infinity Grip, there is a common
wire for the trim top hat switch. Following the Safety Trim wiring
instructions you connect this common wire to the safety trim. To add the
Pilot/Co-Pilot selector switch you insert this (DPDT) switch between the
pilot and co-pilot common wires and the Safety trim. The other four wires
from each top hat switch all go to the Safety Trim - not through any switch.
I did the standard (momentary) on-off-on toggle switch on the Infinity Grip
to operate the standard Van's flap actuator. This toggle switch also as a
common wire. Use the other half of the DPDT Pilot/Co-Pilot to switch the
common wire connection between the pilot and co-pilot.
For other pilot/co-pilot switch configurations:
PPT - this is controlled via the audio panel as to what radio the pilot or
co-pilot controls.
Flip/Flop - I wired the pilot stick to control Comm #1, co-pilot controls
Comm #2. This is very limited value for me to add another switch to change
the pilot flip/flop between the radios. If the pilot needs to flip/flop
comm. #2 then use the button on the radio.
AP disconnect. Both sticks are wired to disconnect the AP. Considering the
Dynon EFIS as an auditable "autopilot disconnected" alert, I will always
know if the co-pilot hit the button.
I used miniature locking toggle switches in the 8A and the 10 for all but
heavy current applications (and I used switch breakers for those - such as
pitot heat and landing lights). They have performed well. Here is an
example of the DPDT on-off-on locking switch:

I just hooked up my aileron trim springs to the left wing pushrod. I wouldn't drill
holes until final pushrod alignment when the wings are on as it's possible
that things won't line up the same as when the wings are in the cradles. I did,
however, pre-wire and mount the servo on the wing access panel long ago.
Cheers,
Jay

agree. Put the alierons on and get the angles up and down completed before
doing the trim for them.

| Subject: | "Co-Pilot Grip activation" switch (was Electric aileron |
trim)
Carlos,
It's a nice way to go but unfortunately I have no schematics which I know will
be shocking for some on this list to believe. :-) But as Tim said " The one single
switch basically disables the ground on the co-pilot side, so one panel switch
can remove all control from the co-pilot." Simple solution. BTW on my 8A
I even placed the Co-Pilots arm switch under a safety switch cover. Up is arms,
down is disarmed.
Good luck,
Robin
