No, the output of an LR3C is intended to directly
drive the field winding of an alternator and it expects
to see a nearly instantaneous response to TINY changes
of DC voltage. The LR3 output varies from as low as 1v in
cruising flight with light loads on the alternator to
some value just below bus voltage. The input signal
expected by an internally regulated alternator is either
fully-on or fully-off . . . and for most alternators,
turning the input command off after the alternator comes
alive has no effect. An externally regulated alternator
brings the field lead out for connection to the regulator
and has a diagram much like so:
http://www.aeroelectric.com/Pictures/Schematics/External_Regulator.jpg
. . . while the internally regulated machine looks like this:
http://www.aeroelectric.com/Pictures/Schematics/Internal_Regulator.jpg
There's LOTS of "stuff" in that box labeled "REG" that
would totally bumfoozle an LR3 or any other external
regulator.

On my RV7 its just not that big of a deal, sure at speed you barely
touch the trim switch to adjust but honestly its not hard to trim it
out.

Subject: AeroElectric-List: Runaway trim
--> <dean.psiropoulos@verizon.net>
Frank is correct:
The folks at the Portland RVators did some testing on the runaway trim
issue and confirmed this. While full up or down trim is difficult to
counter-act when the aircraft is flying at high speed, simply throttling
back and slowing down restores sufficient control authority to the pilot
that a safe landing can be made.
One thing I have not heard mentioned is elevator trim twitchiness in the
RV aircraft. I had heard some folks mention that there is too much
(electric) trim twitchiness at high speed and, trim does not respond
fast enough when the aircraft is flying slow in the pattern. So....I
purchased a trim control module from F-1 Rocket Boy to solve this
(perceived) problem. I have a micro switch that opens when the flaps
are down to send a signal to the trim control module to change the trim
motor speed. One of the design features of this unit is that it has a
runaway trim sensing feature built in. If the trim button is held for
more than 5 seconds (ie. a trim wire shorted to ground), the trim
control module assumes a runaway condition and shuts off the trim motor.
Cycling power returns the unit to normal operating condition.
Does anyone on the list use one of these trim control modules? Is it
worth the time and effort I had to put into wiring it into my system
(the price was reasonable)? And lastly, has it been reliable and does
it always work as advertised? Since the airplane hasn't flown yet I'd
like to know what to expect. Thanks.

No, the output of an LR3 is linear DC voltage intended to
drive the field winding of an alternator at up to 3 Amps;
it expects to see a nearly instantaneous response to TINY changes
of DC voltage. The LR3 output varies from as low as 1v in
cruising flight with light loads on the alternator to
some max value just below bus voltage. An internally regulated
alternator expects a fully-on or fully-off command signal;
not a 'throttled', variable DC level. Turning the input
command off after the alternator comes alive has no effect
on most alternators.
For external regulation the field lead is brought out for
connection to the regulator and has a diagram much like so:

Sounds like what I've got on the back of my SL-70.
If it is, Garmin-AT will probably sell you one for an arm and a leg.....
Otherwise - I don't know....
Regardless, I may be looking for the same thing as I am having some trouble with
my SL-70 and want to do some testing.......

Subject: | Re: AeroElectric-List Digest: 17 Msgs - 11/08/07 |
This runaway trim issue interests me because I had it happen in my RV-4 on
takeoff. Handled it by slowing down to the new trim speed, but now I'm
building a faster, more powerful airplane and am looking for protection from
a potentially more difficult situation. The TCW system sounds good but I
have a TruTrak ADI Pilot II and was wondering if they are compatible and if
there is any sense in which they would work against each other. Does anyone
know how these two systems would work together? Does the TruTrak provide
any protection from runaway trim itself, or would it be better to have both?
Thanks and regards,
Lee...

Bob,
Does this unit allow independent control of multiple units? I'm considering
a solid-state relay deck for control of my trim actuators, one of which can take
up to 5A. This may be the right device for me.
Thanks,
Dan

Sounds like the slip-fit coax connectors
crafted back in the 60's to allow a radio
to be easily removed from the panel for
maintenance leaving the harnesses attached
to the tray. See if this isn't the critter

No doubt the supplier listed is but one of

Matt's lists cost you the sight of a couple of donation-request emails
per year. Contribution is voluntary.
On the other hand, it's pretty hard for me to think of dealing with the
clunkiness of Yahoo as 'free'...

I know I shouldn't reply to issues like this, because my feelings and
emotions on the matter and my way of wording replies sometimes gets me
in trouble, but here goes anyway. Flame suit on. (If necessary)
Gary;
#1 Very kind of you to append the whole of today's digest messages to
your reply. (see Matt's rules of conduct for use of these lists)
#2 How considerate that you think Matt should fork out the mega $$$$$$
it costs to support/run/host these lists without any consideration from
those who benefit from their existence. (You and me. Matt's not the one
gaining here)
#3 I, for one, appreciate the ease of use, and especially the freedom
from clutter/adds that these lists provide. They are FAR easier to use
and follow without all the annoying junk found on Yahoo. (your example
alternate)
#4 I'm not yet building (Falco F8L), but only presently lurking (with
the occasional post) and gathering, what I consider to be, volumes of
valuable knowledge. (and in my opinion some of the most progressive
knowledge going. Between Bob Nuckolls, Stein Bruch, Eric Jones, and even
sometimes gmcjetpilot, to name just a few of the knowledgeable souls on
this list, how can you go wrong???)
#5 The entertainment value alone is worth the token amount Matt requests
of us each year. Heck he doesn't even specify how much, leaves it
entirely up to you what you feel is fair.
#6 When this list provides information or assistance to you which saves
you time , $$, $time$, or damaged components, (more$$$$) maybe you
should consider giving that money to Matt.
#7 Maybe the cost of the electrical course you don't need to take
because of subscribing to this list should be forwarded to Matt????
#8 Maybe the $$$ you save by not having to have someone else sort your
electrical issues should be sent to Matt?????
#9 Or maybe, just maybe, you should consider sending your token
$10-$20-$30-$40-$?? like most others for one of the most valuable,
convenient, informative lists going. Where else can you get Bob N's sage
advice for so little??? Certainly not on Yahoo!
Rant off.
Matt, some of us do appreciate the format. Thank you so very much. The
$$ is well worth it.
