--> Zenith-List message posted by: "Richard Shults" <shults@anvilcom.com>
I've ordered the wing kit for the XL and included in the order is the
ZAC-supplied Nav-Strobe lights with the position light on the rudder.
I saw a Nav-Strobe-Position light set on the Aeroflash web site.
http://www.aeroflash.com/aeroflash_nav_strobe_position.php
I don't have access to a XL wing tip to see if this light assemble
will fit on the mounting area. The light base is 1.759 X 5.565 inches.
Would someone mind seeing if this light assembly will be usable with
the ZAC-supplied wing tips? Any other concerns I'm missing?
Thanks..........

I believe it is for the 3300, when I bought it from Jabiru I ordered one for
my 3300.
+++It will fit either the 2200 or 3300. It's the motor mount that will be different.
Of course, the RamDucts will be for the longer six-cylinder 3300.

I have had nothing but trouble with Aeroflash units over the last 6
years. I would not buy them again.
The main capacitor in both power supplies leaked and I was told to send
them back at $50 a pop...No thank you.
You can replace the capacitors yourself...I've gone thru 3 sets in 6
years.
The heads seem reliable though.
Of course they may have been improved since I bought mine

Jeff, Tony brings up a good point:
"You might check your UP flap setting. I find that just a few degrees of
flap can easily give up 5 kts top speed."
I actually adjusted one flap which wasn't going quite exactly up as far
as the other (measured at the trailing edge) - now they are exactly the
same. I've not done much performance testing since, but some extra knots
are apparent.

Hi Bill,
I didn't know that the prototype was that heavy! It does have a bunch
of old rotax engine wiring, maybe that's it!!. ...and I'm unpainted at
the moment, with no wheel pants. I'm very light in the engine/panel area
I think. My panel is mostly devoid of heavy steam gauges too, and the
electronics are very light:
http://lancegingell.com/planebuild/DSC06352.JPG
The skyshops seats I have are VERY light. definately lighter than the
leather demo ones (which I held).
I will be adding some carpet and firewall insulation I expect (and
paint), which will bring me closer to yours!
Cheers,

Since there has been so much interest in the pre-heat subject,
thought I'd share the following website which shows an electric milkhouse
heater application for the Zodie 601HDS. It also works with wheelpants,
just need to trim it to fit at an angle. Heats the engine to above 50 F in
about 20-40 minutes, depending on the outside air temp. Cost about $30-$40
dollars, and takes 2-4 hours to build. The original idea came from the
Jabiru USA website.

I don't have access to a wing tip yet to measure but I did ask a factory
rep this very question the day I flew the factory plane. The other
concern I had was the mounting areas angle forward a bit so I was
afraid the rear facing white lights might be obstructed from the rear.
They assured me they work fine and several builders have used
them successfully. Now I'm not sure about the brand, I was also
looking at the ones from Whelen.

For the last year we have been using the GS-Air LED position light / strobe
light combo. We like them a lot. The LED position lights are brighter than
the Whelan or Aeroflash and only draw 250 milli amps of power per side. The
strobe is a triple flash and appears just as bright as any of the others.
Cost is much less than Whelan. See them at www.gs-air.com.

Greetings from Seattle-
I'm beginning the 701 plans building adventure and have been pouring over my plans
for several weeks and have a question or two.
I notice that the fuselage is wider at the bottom than at the top. Anyone know
why it's not truly square? Same for the fusealge sides and top. They bow slightly
in the middle.
Thanks for everyone's contributions to this list. It's been amazing what I've been

I think that the capacitor problem is not a buy or no buy decision maker, because
all of them use a capacitor of some sort to make the flash.., and as any
electrical part can fail any moment. I have Aeroflash for about 3 years (2
in the box and almost one flying) with no problem (knock wood).
In case of capacitor fails, well we just will buy another one and carefully change
it, like the light bulbs...

I have a MAC electric trim (from ZAC). The LED indicator used to work OK, now
as you change the trim some of the LED's don't come on, they are blank and then
the next one will come on. The ones that don't work are always the same, about
4 out of 10. It looks like there are 3 signal wires and 2 power wires to
the indicator. Does anyone know how the signals work, are they a voltage level
or what?
Thanks,

This has been a problem for some time with MAC LED trim indicators. They
have replaced several for free for friends of mine stating they had received
a batch of bad units. Give them a call and see if they will do the same for
you. http://www.rayallencompany.com/
BTW, I believe the LED bar graph is a single unit and not individual LEDs
that you can replace. Similar to:

Capacitors driving xenon flash tubes are not off-the-shelf capacitors.
I believe
capacitors suitable for flash units have less internal Resistance. I
would think
the internal heating effects would be especially important in a strobe that
repetitively fires.
"Please note that the above electrolytic capacitors generally do well
only with
flash durations at least half a millisecond, preferably a millisecond. For
shorter flashes likely with repeating strobes, I recommend laser energy
storage
capacitors or a bank of AC-rated motor run capacitors."
(http://members.misty.com/don/xebig.html#c)
"All capacitors should be rated at a minimum of 350V (preferably 450V). The
storage capacitor can be a standard electrolytic, but its life will be limited
due to the high discharge current. You might be able to get hold of a few
disposable cameras and nab the capacitors from these (they probably won't last
very long either, but they're cheap :-)"

--> Zenith-List message posted by: "Zodie Rocket" <zodierocket@hsfx.ca>
Hi Chris, Nick or Chris Heintz are the best people in which to get the
facts from concerning your question. But that doesn't stop any of us
pondering it and offering suggestions as to the design choices.
The CH701 does one thing exceptionally well! It has a STOL performance
which is hard to match by any other aircraft including the planes
clones. Originally the CH701's design called out for a 503 power plant
and a 68-72 inch prop. My line of thinking is that the fuselage was
designed to allow the most thrust from the prop with the least amount of
power. By bowing in the middle, I believe that it allows the plane to
perform better in the STOL conditions in which it was designed for. Now
with the design changes and the increased gross to accommodate the Rotax
912 series I doubt that this design portion is still a necessity. But
knowing Chris Heintz, simplicity rules and why change for change sake.
Well that's my 2 cents, sounds good in my grey matter. Though I could be
totally wrong, when I see Chris later this month I will ask him.

Capacitors are not magical devices. They are incredibly simple
electronic components which are made to specifications. If a
capacitor meets all the specifications for the design it is acceptable for use.
If you want to replace capacitors in Aeroflash brand products, then
find out what the original components were and use the same ones. As
an alternative, get capacitors meeting the exact same complete
specification. Aeroflash may tell you which vendors and specific
products have been approved for use in their system if you just ask them.

| Subject: | Nav strobe lights |
--> Zenith-List message posted by: "neitzel" <n963wb@frontiernet.net>
Greetings all
I recently purchased nav/strobe lights that are similar to the ones by gs-air.
The lights I bought also include the white light on the back side (and only weigh
3 oz ea) so I will not have to run a wire to the tail and put a light on
the rudder. The price for these lights with the power supply was $329 (shielded
cables extra and not that expensive 20 foot cables $12.65 ea). The power supply
(17 oz) is extremely versatile as it is programmable to perform 12 different
flash patterns of your choice. If you are not satisfied with the flash sequence
it can be easily changed. The power supply pulls 40 watts and the LED
position lights draw next to nothing. Warranty seemed pretty decent too at two
years on power supply and LED's and one year on strobe bulb. I was also impressed
with the dealings I had with the owner Rob Rollison. When I placed my order
he was out of power supplies and said he would ship as soon as he could.
I explained that I was getting close to closing the right wing and would need
the lights and cables shortly. He volunteered to send the cables at his expense
just to keep me building. Thought that was pretty decent.
These lights can be see at:

Happy building everyone!

Who said anything about magic? Resistence is a very real unit of measure.
Explain this to me - what is the difference between a ceramic disk
capacitor and
a mylar capacitor of the same value?
Yes, what part of the specifaction describes their internal rssistance?
Batteries are also incredibly simple devices. Try this test:
short-circuit your
car battery and then short-circuit a 9 volt radio battery. What explains the
differnet results? Amp-hours? Nope. Voltage? Nope? Internal resistence? Bingo.

If you still don't believe in magic then perhaps you should read this
(especially the part that says "Strobe capacitors use amorphous alumina rather
than the usual crystalline alumina"):
"Strobe capacitors are used at high repetition rates. In the case of
low-voltage
units, the repetition rate may be very high, high enough for use in
party strobe
lights and in automotive tachometer lights. High-voltage units
generally cannot
be operated in full charge-discharge mode beyond about 2 or 3 Hz repetition
rate, or rep rate. High-voltage aluminum electrolytic strobe capacitors use a
different alumina dielectric structure than their photoflash and filter
counterparts. Strobe capacitors use amorphous alumina rather than the usual
crystalline alumina. This is accomplished through the forming process when the
foil is anodized. Different pre-processing, process temperature and current
density, and different electrolyte chemistry is used. The resulting dielectric
is unfortunately much thicker than its crystalline counterpart. For this
reason, strobe foil has larger tunnels and strobe capacitors suffer in energy
density and cost by a factor of about four against their crystalline cousins.
But their repetition rates may offer a factor of twenty improvement, and their
life duration may approach 1,000 times the number of sustained
charge-discharge
cycles. When one only needs a fractional discharge, such as discharging
from 400
V to 250 V, instead of full-discharge, hybrid capacitor designs can be
developed
which offer high repetition rate, long life, without the sacrifices in
cost and
size required by amorphous foil."

--> Zenith-List message posted by: Gary Gower <ggower_99@yahoo.com>
The bow in the middle, is part of the "structure rigidy" of the "box" fuselage.
Just remember the experiment of the egg, will not brake as easy pushing from
the ends that from the sides... also how an arc in a bridge "works" as a structure
when weight is aplied in the center (this is a very looong arc).
This type of structure "trick" is used to lower the caliber (and weight of course)
of the aluminum chanel used as longerons...
Al this (including the bunch of "Ls"), are part of the rigidity of the semi monocoque
type of design of the Zenith Airplanes.
Yes, Mr Heintz is a Genius. Is extremly dificult to design Simple and Efective
things...

Hi Chris, Nick or Chris Heintz are the best people in which to get the
facts from concerning your question. But that doesn't stop any of us
pondering it and offering suggestions as to the design choices.
The CH701 does one thing exceptionally well! It has a STOL performance
which is hard to match by any other aircraft including the planes
clones. Originally the CH701's design called out for a 503 power plant
and a 68-72 inch prop. My line of thinking is that the fuselage was
designed to allow the most thrust from the prop with the least amount of
power. By bowing in the middle, I believe that it allows the plane to
perform better in the STOL conditions in which it was designed for. Now
with the design changes and the increased gross to accommodate the Rotax
912 series I doubt that this design portion is still a necessity. But
knowing Chris Heintz, simplicity rules and why change for change sake.
Well that's my 2 cents, sounds good in my grey matter. Though I could be
totally wrong, when I see Chris later this month I will ask him.

>> I don't have access to a XL wing tip to see if this light assemble

>> Would someone mind seeing if this light assembly will be usable with
