| Subject: | November is Matronics Email List Fund Raiser Month! |
Dear Listers,
You've probably noticed that there are no banner ads or pop-up windows or spam
from any of the List and Forum services at Matronics. These include, for example:
The Email List Postings - http://www.matronics.com/listbrowse
The Email List Forum Site - http://forums.matronics.com
The List Wiki - http://wiki.matronics.com
The List Search Engine - http://www.matronics.com/search
This is because I have always enjoyed a List experience that was completely about
the sport we enjoy - airplanes - and not about advertising!
But running a high performance, highly available service like this isn't free and
a fair amount of money in terms of computer upgrades, business-class Internet
connectivity, and electricity. Consequently, many similar sites turn to advertising
to support these costs. Advertising that you have to look at each and
every time you read an email message or browse the their web site.
Rather than subject my List community to another constant commercial bombardment,
I have chosen to hold a PBS-like fund raiser each year in November to support
the continued operation and upgrade of the List services. It's solely through
the Contributions of List members that the Lists and Forums continue to be
possible!
During the month, I will be sending out a Fund Raiser reminder message every few
days and I ask for your patience and understanding during the month throughout
these regular messages. Think of them as PBS' Pledge Breaks... :-)
To minimize the impact of the Fund Raiser on the List community, I implemented
a new feature late last year specifically related to making Contributions. If
you are an Email List subscriber, once you make a Contribution using the online
web site, you will no longer receive the email from me regarding the Fund Raiser!
There are a couple of exceptions to this, however. If someone replies
to a Contribution message I've sent, you might receive that. Additionally, the
messages will always be posted to the Forums site. To a first order, however,
once you make a Contribution, you won't get my email messages about the Fund
Raiser for the rest of the month. For Contributions by check, the squelch
will take effect once the check is received.
There is a whole new line up of really great Contribution gifts this year! When
you make a qualifying Contribution, you can select one of the many free gifts
that are available during the Fund Raiser. These gifts are provided through
the generous support of a number of our industry's leading supporters including:
Bob Nuckolls - AeroElectric - http://www.aeroelectric.com
Andy Gold - Builder's Bookstore - http://www.buildersbooks.com
Jon Croke - HomebuiltHELP - http://www.homebuilthelp.com
Please visit these guy's respective sites, as they have some great products to
offer and are generously supporting the Matronics List Fund Raiser.
You can make your List Contribution using any one of three secure methods this
year including using a credit card, PayPal, or by personal check. From the Contribution
site, you can select any one of this year's free gifts with a qualifying
Contribution amount. The Contribution page is pretty loooonnnnng this year
in order to list great selection of great gifts available so be sure to scroll
all the way to the bottom of the web page to see everything that's available!
Please make a List Support Contribution:
http://www.matronics.com/contribution
I would like to thank everyone in advance for their generous support! Your Contributions
truely keep this operation afloat!
Thank you,

I solved the problem. The diodes that are installed to isolate the switches
on the panel from the relay were the issue. I also hooked the stick
switches up to the diodes but it won't work that way, switched it around and
all is well. Ray Allen is not sure why it won't work that way but they said
to try switching it and see if it works.

I don't think it negates all possibilities....with both the relay
system, and the Safety-Trim system, I had a panel mounted Elevator
switch (Ray Allen Type), and 2 stick switches, and all 3 switches
worked fine. You just have to piece together the proper diagrams
from Ray Allen and then it all works together. I know someone
mentioned diodes already, and I think I had a pair in my install
too, but I haven't taken the time to re-think how I put that all
together....but I do know it works.

William, doesn't the DPDT switch takes the place of the need to have two
SPDT switches on the panel, i.e one way for forward trim and the other for
aft trim?
The SPDT switches on the pilot and co-pilot sticks each look after forward
trim or aft trim individually. I would have thought the intention would be
to have all three switches operating exactly the same, the only difference
being a fore and aft option in one convenient switch on the panel.

The caveat was IF YOU WILL BE USING A RELAY DECK. Without the relay deck, yes
you would need two SPDT switches. The momentary switches in the pilot stick are
SPDT. Replacing the DPDT (center off) panel rocker switch with a momentary
SPDT makes all switches the same. Your panel switch will just be another switch
like the ones in the stick.

Yes, but with a relay deck you can use the original panel switch, and
2 regular sticks switches like the infinity grips use, and use
them all together with no problem. Same with Bob's trim system.
One question William...your pilot/co-pilot switch....when you flip
yours, you disable the pilot if it's on co-pilot. Don't you want
the pilot to always have control, and just have the co-pilot only
be dis-connectable?

Do you remember the value of the resistor? I would like to slow my trim
in cruise as well, this looks like an inexpensive solution.

Fellow listers,
Thru this recent thread regarding a trim switch/relay problem I've
offered some troubleshooting ideas to help solve the current issue at hand
and have not brought up any of my commercial interests regarding
Safety-Trim. Now that it seems to be sorted out and the root cause was
determined to be an issue with diodes and the Ray Allen trim switch I'm
inclined to chime in. I realize different folks want different levels of
complexity in the aircraft and I fully support that. As a fellow RV-10
builder and a Glastar builder I have enjoy making the decisions how my
airplane will operate and how complex or not it would be.
I'd just like to make you all aware that one of the benifits of the
Safety-Trim electronic servo controller is that the switch wiring required
to accomplish multiples points of control is greatly simplified over that
traditionally done with a series of relay decks. All of the switches
used in a Safety-Trim system only need to be SPST for each function, each
is just a simple closure to ground. Safety-Trim handles any comflicts
between the pilot and the co-pilot and/or a panel mounted switch asking for
different directions. This benefit is in addition to that of the
run-away prevention technology and 2 speed preset functions also found in
our controller.
For all the details and to see our instruction manuals, please visit

Thank you,

I installed my system last week (its the latest version with the wheel and cable),
and had the exact same issue. I just shortened the spacer to the length that
made it work. Let me know if I missed something.

I only have about .28" of space between the bellcrank bracket and the MM-3-300
rod end bearing. The TruTrak Pitch servo plans call for a (supplied) .438"
spacer in that space. If I put in that thick of a spacer the whole thing would
be very cattywhompus and would stress the drive on the servo and the bearing
on the bellcrank. (Yes, I did double check to see that I reinstalled the drive
wheel properly)
If anyone has had the same issue please let me know.
Also, as this has been an all day ordeal - calling Zach at Trutrak three times
today, I intend to post installation instructions for the servo tomorrow.

Right now it is variable. Until I'm flying I won't have a specific value for the
resistor.

That is; if you will be installing a relay deck, replacing the provided
DPDT rocker switch with a momentary SPDT switch, simplifies the wiring greatly.
I built my own relay deck and incorporated a simple two-speed (Normal/Cruise)
switch. The switch places or removes a resister in the power path to
the servo motor.

| Subject: | Re: Trim troubles |
Tonight I went about the task of hooking up my rudder trim. Last
week when I finished the Safety-Trim I didn't know 100% that I'd
be adding rudder trim. I just plunged in after I finished
that project. So tonight I finalized the wiring and tomorrow the
entire job will be done.
To do the rudder trim, I decided to run that trim servo through
Bob's controller, instead of aileron trim. I think the elevator
is the axis in desperate need of speed control, but I think the
rudder would be likely to get the 2nd vote, just because you
want to fine tune it so much. Aileron trim I believe would
not benefit from speed reduction. So, I removed the aileron trim
from the Safety-Trim controller. Very easy since it's just 4 wires.
Then, I wired in my rudder trim in it's place. But, I wanted the
stick hat switches to run the aileron trim as before, so those
went to that system instead. I used the standard Ray Allen
switch for the Rudder Trim switch using Bob's box.
That brought me back to the old days of wiring the switches and
how I accomplished it. I believe with relays, I used diodes
on that switch. On Bob's box it's simplified beyond that.
What you do is to hook the RED wire to ground, and that switches
that line to either side of the switch to ground the system
and drive the controller. I think this is what I did on the
panel mounted elevator switch, but I used diodes because the
relay system required it. Using Bob's controller though,
even though those 2 white wires tie together in the neutral
(non-activated) position, it causes no problem with the trim
controller, so it was Red wire to ground, and a white to each
of the 2 wires for rudder trim input. Then it was just a matter
of the 2 wires to the servo, and done.
So anyway, it was a quick job tonight, but now all 3 axis are
trimmable, with the aileron and elevator on the stick (elev.
on the panel too), and the rudder on the panel only.
Can't wait to give it a couple thousand miles of testing
next week.

Yeah, you got me there!!! :-( . It does say 'trim troubles'
doesn't it???
Some folks really do read my drivel!!!
OK, now back to the question:
Why are there TRIM switches on the stick AND the panel???

I haven't been following the TT pitch servo thread but whatever you do make
sure that the servo can not get into an over center lock. A locked elevator
means pruning of the gene pool.

I had a look at my spacer on the servo last night and I would say it's
definitely closer to the .438" size rather than the .280" as Mike has
described.
All is square.
I would check with TruTrak until they can identify to your satisfaction,
what has changed.

| Subject: | Alternate static switch |
Hey all -
a bit of discussion awhile back about ways to do alternate static air,
and i promised i'd report back on my findings. The long and short is
that the toggle valve from clippard seems to be super cool. seemingly,
it works well with the Safeair1 static quick connect kit. i've
blathered on about it on my site here:
http://www.perfectlygoodairplane.net/Perfectlygoodairplane/Alternate%20St
atic%20switch.html
anyway, the part# for the clippard toggle valve is the TV-2SP. I
Haven't actually installed it and done a static system leak test or
anything, but hopefully when i do it won't leak :)
