Does anyone know of a source of small Acme drives? I'm looking for
something to be manually operated with an operating range of 1.5 to 2
inches, about 3/16 or 1/4 inch diameter. I plan to use it to load a spring
for a manual rudder trim in a Glasair.
Thanks,
BJC

Anyone know what type of electrical system was on the Voyager? Just curious
how they handled the redundancy question.

Good Morning Gary,
I don't know anything about the Voyager, but it has been said that the very
first Twin Beeches (Model 18) had two entirely separate electrical systems.
One for each engine. I have never seen one in that configuration. Most were
converted to a balanced system along the way. I was told that each side had
it's own twelve volt battery in the wing near the nacelle. Some of the
electrical components had single pole, double throw, center off switches.
The pilot could select which system would supply the equipment. Others were
only connected to one side or the other. For a twin, that has possibilities!
Happy Skies,
Old Bob

Don't know of an 'Acme drive' that small, but the Ray Allen servos would
probalby fit the bill and they are designed specifically to be trim servos.
They may not have quite the travel that you are looking for but the are
torquey little beasts and you could rig a small lever mechanism. This is
the way the aileron trim is done on the RV's.
Here is a picture of the aileron trim servo installation in my RV-7. I
don't know if you can tell exactly how it works from the photo but it may
help...

Done it twice. Peltors. Works good last long. The second one showed some
improvements. Good company. Need a soldering iron, and bout $200. A
little less for other brands. The ANR performance is at least as good as
the others.
If you have a headset you really like, it is the way to go. If you are
starting from scratch it is a tougher choice to make.

Don't know if Bob designed the system/s but I think it had B and C
alternators/PMGs, and regulators.
He has mentioned it here, but only briefly if I recall. Bet he could
tell us lots about that plane.

Take a look at "Small Parts". It is a great resource. We purchase a lot of
items from them. Prices are not great, but if you only need a few of
something they sell in small quantities. I purchase stuff from them often
for a project because I can find everything I need at one place.

Bob designed the regulators that were used on the Voyager, the LR-1's.
This was the predecessor to the LR-3 that B&C now sells. The
alternators were not original B&C designs. I believe that B&C procured
some OEM type alternators from AeroElectric in Wichita, (now a Kelly
Aerospace division called Turbine Rotables, no connection with Bob's
AeroElectric name), and performed some type of modification to them. I
have no idea how the power distribution system was configured on the
Voyager, Bob probably does.

The National Institute of Technology and Standards (formerly known as the
Bureau of Standards) gives this value for Avogadro's number:
Avogadro constant 6.022 141 99 x 10E23
Standard uncertainty 0.000 000 47 x 10E23
See

er
Since this is the government speaking, that must be right, huh? Actually,
the NIST site, http://www.nist.gov/ is a good source for conversions factors
and constants of all sorts.

Hi all,
I believe Jim Weir also esigned some antennas and maybe some parts of the
electrical system too.

Bob, yep, I get the "clunk" when I turn on the master. I also checked my
installation and the ground wire to the firewall is there, so that's not the
problem.

--> AeroElectric-List message posted by: "royt.or" <royt.or@netzero.net>
Another encoder option to consider, especially with GNS430 is the
microEncoder
from Rocky Mountain Instruments. http://www.rkymtn.com/. At $879 for the kit
version, it is not cheap as encoders go, but it is inexpensive for the added
capabilities it enables in the GNS430. In addition to being an encoder, the
microEncoder displays and can supply the GPS with altimeter setting,
airspeed, vertical speed, OAT, and with the optional $250 compass module,
the magnetic heading. Not having to enter this information manually into the
GPS sure seems like it will reduce pilot workload. I just completed my 3rd
flight on my (over equipped?) plane and it was cool to have the wind vector
arrow in the GNS430. The Air Data computers reviewed in May '03 The Aviation
Consumer cost ~$3000 to provide this information. Granted the $3K air data
computers supply fuel flow/capacity information also. Too bad the fuel
totalizer in my EIS does not output information for the GPS also.
My panel was built by Pacific Coast avionics. I'm using a Garmin GTX327
transponder. I'm not certain which communication interface goes between the
units, but I don't believe there were any diodes included. I can get more
details if needed.
One other Garmin feature: I have my GNS430 linked to my portable GPSMAP 295,
so that the flight plan in the GNS430 is automatically loaded into the
GPSMAP 295. That way if I lose my GNS430 for some reason, my GPSMAP 295 has
my flight plan. If the GPSMAP 295 loses ships power, it switches to it's
internal batteries AND has my flight plan loaded.
