David & others,
I recently had some CAD files in DWG format sent over from another lister,
and discovered that CorelDraw could import them. Okay, it doesn't do the
best job in the world, but it's all there and looks exactly as intended.
Personally, I can't make head nor tail of most CAD programs, so it was a
blessing to discover that Corel could understand the format.
Hope this helps.

Thanks for the comments. You're right about the origin of .dxf files being
AutoDesk. It is still the accepted standard and about the only way one can
have a reasonable chance of getting various programs to read vector
drawings.

If one considers the goal of achieving "gas tight" joints
between metal strands of wire and metal wire grip barrel
of terminal, then the terminal and wire become one piece
of metal. It stands to reason that the wire or terminal
will break before you pull the strands from the terminal.
If a pull test does release the strands from the wire
grip, then there is a mis-match between tool, terminal
and/or wire . . . or the tool is worn out (which is rare).

Your experience reenforces the idea that folk
who promote a superiority of solder or crimp+solder
over crimping alone simply don't understand how the two
systems work and what their respective limits and
capabilities are.
Thanks for sharing your observations and conclusions.

Sounded good but..... Unsure what figures 'gain' based on and 19 AMPS
current drawn. That probably uses up any useful gain in HP.
Maybe I'm wrong.

I would recommend not spending your money on this item. While it just might
be possible to get 2 psi pumping from this motor into a closed duct (or
box), however, there is no way it would maintain 2 psi in the manifold of an
engine sucking 200 -300 + cubic feet per minute of air. In fact, the
airflow of the engine sucked throught the fan would probably cause it to
spin faster, but actually impeding air flow..
It would consume approx 266 watts of electrical power (14 Volts x 19 amps).
This equates to approx 0.357 HP. IF it could provide the 2 psi claimed and
you had a 160 HP engine, then the 2 psi would equate to 2+14.7/14.7 *160 180 HP
or a 20 HP boost (actually it would be somewhat less due to the less
denser air caused by the 2 psi compression process). So here we have a
device consuming 0.357 HP and resulting in a 15-20HP gain, not bad in my
book, in fact too good to be true.

We use a viewer available on the Autodesk site called Voloview. The
full program costs money ($49 until Jul 31) but there is a version
called Voloview Express that allows viewing and printing DWG files and
is free. We use it at our business so people without AutoCAD on their
systems can view and print drawings. It seems to work just fine for that.
I would list the correct URL, but it uses cookies and would probably not
work. So... Go to www.autodesk.com , choose United States and then
click on "products" in the upper left hand box. At the bottom of the
subsequent window Voloview and Voloview Express is listed. Click on
whichever one you are interested in and proceed. The download is 24MB
so hopefully you have a broadband connection :-) . The latest version
will run on Windows 98Se or better so if you are still running Windows
95 it won't work. I do have a previous version that works with the
latest AutoCAD (but not the new version 2004) and Windows 95 that I
could provide (somehow).

If it really provides 2 psi (IF), that is an increase of 13% over over
sea level atmospheric pressure. Which (in a perfect world) would
provide a 13% increase in HP output. Even assuming that their lower
predictions (+10 HP) is correct then the modest 19 A @ 12V (228W or .3
HP) only uses a small percentage of that. Of course, the conversion
from motor HP to blower HP is not 100% efficient, but even assuming 30%
efficiency, that still is only 1 HP lost to power the blower for a net 9 HP.
I am certainly not endorsing this product, but at least it looks like it
could provide more output than it takes (at a cost of more gas of course
:-) ).
YMMV...

Hello Gang,
This might sound a little bit strange, but after it
has happened six times in row I feel it is justified
to bring it to your attention.
Last year we installed in our LongEZ an EGT and CHT
from Aerospacelogic in Canada. For those who are not
familiar with
these units, they are 4 channel digital instruments
displaying the hottest cylinder or step from one to
four. They work
very nice and besides having some trouble with the
installation we are very happy with them. When I
originally installed them
they worked fine with the alternator turn off, but
with the alternator charging the gauges showed extreme
low temperature or
COLD. I tried to fix the problem with additional
grounding. (close but no cigar).The Aerospacelogic
customer was very helpful
and ultimately they send me two replacement units with
a different grounding system. After solving this
initial problem EGT/CHT
we have flown 100 hours and the instruments are
working fine and wouldn't have anything to complain,
but since the installation
of the gauges they failed every single time in
approx.15NM radius around Bakerfield(BFL) , showing
the same symptoms as described
above. The Burtday trip really took the cake, our
standard EGT/CHT malfunction came with soundtrack.
Mysteriously we heart
a Mexican radiostation in our headsets. A glue to the
EGT/CHT malfunction might be the microwave tower
depicted on the chart
in this area. I am wondering has anybody encountered
similar problems in this area or similar problem with
the Aerospacelogic instruments.
Thank you for all your help.

Common problem with thermocouple instruments that
do not isolate the thermocouple electrically from
the engine . . . "additional" grounding wouldn't
have helped but I'll be that moving the instrument's
power ground from the ground bus up front to a crankcase
ground would have solved the problem. See first
column of page 5-7 in the 'Connection. This is
a very common problem with canard pushers.

Plastic airplanes are "wide open" when
it comes to ingress of external RF sources. FM
and TV stations are particularly vicious because
of there VHF and higher frequencies, high power
transmitters and antennas that focus transmitted
energy into a flat disk radiating toward the horizon.
Since you're aware of this problem, I'd let
it ride. It's a relatively rare, short duration
event that affects readings that do not help
you fly the airplane. The time and effort
to eliminate the problem could be extensive and
will only drive up parts count (drive down
reliability and could affect accuracy).

Ferg-
The crimper I purchased is good for AMP PIDG style connectors/terminals
that fit into the color coding scheme of Red, Blue, and Yellow. Off the
top of my head I believe this covers the 12 to 24 Gauge wire sizes (give
or take a couple gauges). These are the most common style of
connector/terminal used when wiring and are needed if you plan on using
BK's fuse panel design and/or the switches available at Aero-Electric. I
don't have it handy, but if you'd like the part # at Mouser/DigiKey
and/or a link to Tyco/AMP's website just let me know.
With that said, it will not work for crimping larger
connectors/terminals - like 4 guage battery leads and so on.
Because of various other projects and so on, I think it's well worth the
investment to buy one. That way when your dealing with common wiring
connections, you'll have the right tool for the job. I would also
recommend buying an assortment of the AMP PIDG connectors/terminals.
Nothing like have a box full of connectors to make the job go easy.
As a side note, I've also fallen in love with the mil spec pins for DB
style connectors. I never knew making these could be so darn easy.
That's another crimp tool that I'm happy I purchased and learned about
on the Aero-Electric site and directly with BK. Except for the cost of
the pins which for small projects is manageable, I can't see any reason
to pull out the smelly old solder iron for most projects.
Good Luck,
Don

Don,
You sum up your last message,
"Before I was trying to avoid crimping connections, now I can't imagine
not crimping a connection." ...... but you don't say what size/type
connection it is. Is this $120 crimper good for all usual terminals,
plus 9/15/25 AMP-style subminiature connectors?
Just curious before buying/renting/borrowing for
connections. Cheers, Ferg

Unfortunately claims can be made about anything (for a while) regarding
performance, but 800 CFM! that is more airmass through-put than a 350 CID
V8 can suck at 6000 rpm.
That means that little fan must flow (at 800 cfm) 1.15 pounds of air per
second, 70 pounds of air per minute or 4, 144 lbs in one hour. Furthermore,
if the exit airduct is 3" in diameter = 7 sq inches, this unit must
accelerate that airmass from sitting still to approx 300 ft/sec in what
appears to be approx 6" distance. Now, if they have a little 1/3 HP motor
that can do that, then I want to buy stock in the company producing these
units. .
Anyone is certainly free to spend their $$ for such items, but you will be
disappointed. These units have been advertised on e bay running from $49 to
$249, so pick the cheaper one if you are really interested in one. It would
be nice as I am currently looking at putting turbocharger on my engine and
will eagerly jump on such a device if it would give me even 1.7 psi at 800
cfm, it would be well worth the money. But, unless somebody has repealed
certain phyiscal laws, it sadly - ain't gonna happen

Ferg,
The Pro Crimper II tool can crimp D-sub type pins, Mate-n-lok, BNC, PIDG and
a whole bunch of others. The dies for the different pins have to be bought
separately though.

Bob,
I'm trying to source the B-crimp style terminals used in connectors for B&C (and
similar) alternator field connections. I've tried everywhere from Radio Shack
to Digikey.. I'm probably searching using the wrong name.. Can you advise a
name, P/N and/or source?

"b-crimp" . . . the term I know is applied to the manner in
which this tool:
http://www.bandc.biz/BCT1info.html
folds the wings of a sheet metal pin down on the wire
as described in this article on Mate-n-Lock connectors:
http://216.55.140.222/articles/matenlok/matenlok.html
Note the shape of the female side of the die in first
photo of the article. The "butt-cheeks" shape of the
die produces the "b" shaped crimp around the wire strands.
Terminals that mate with the B&C alternator field connections
are 1/4" Fast-On tab terminals described at
http://www.aeroelectric.com/articles/faston3.pdf
and sold down near the bottom of the page at:
http://www.bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?12X358218

I'm clearly confused by your reference to the second bus in Z14 as the
"fantasy" bus. I am using that bus for critical items such as my backup
electric gyro and essential items that the smaller of the two
alternators can safely run. Otherwise most of my critical components,
including the FADEC are dual-homed so they will work off either bus
without having to throw the cross-feed.
Are you implying that the 2nd bus is unnecessary in an all-electric
aircraft? If so, how can I feed one primary bus with two alternators
etc. and an automatic cutover?
On the FADEC issue, there is no question they are erring on the side of
caution (and their STC) as you are well aware producing SPAM cans for
the general public. I suspect they have no choice.
I as most builders on the other hand am striving for a much better
electrical system design than most production aircraft ... one that
brings the aircraft into the 20th century. Just like the FADEC finally
brings engine technology into the same. I'm stuck in the middle trying
to strike a balance between the two ... thus my questions to experts
such as yourself.
Regards,
David

I also searched everywhere for these. I finally gave up and called B &
C and they agreed to send me a couple extras in the mail. I suggested
to them that a couple spares included with the alternator might be a
good idea. They did say that these are not even on their website, but
they do stock them. Give 'em a call.
