Greg, Dave, Mike and others:
I've been reading your posts on Aeroflash strobes. I'm fortunate to NOT
have purchased lights yet. I have been kicking around the idea (maybe out
of ignorance) of purchasing an emergency vehicle strobe kit for my wing
tips. Can anybody tell me why this would not work (flash rate, power usage,
etc.) I am surprised I haven't seen mention of this. There is a small
strobe that is mounted inside the headlight bucket on emergency vehicles
that flashes. The electronics and capacitor can be mounted just about
anywhere.
Has anybody thought of this and shot down the idea?

I just wanted to make the comment that Aeroflash is not the only one to have
problems with electrolytic capicitors in storage. In the nuclear industry we
run into it all of the time with spare parts. The solution being we have
procebures to take them out of storage and power them up every 6-12 months,
to reform the capicitors. Do you have to, no but if you do you improve the
odds that you won't have a problem. Electolytic capicitors are still
generally considered to have only a 5-10 year life although many last much
longer.

In response to the builder who wanted a glove box on the outside of the
plane to conveniently hold his fuel cup, saw a Piper Colt where the owner
installed a couple of clips on the firewall to hold his fuel cup. When he
opened the cowl to check the oil, there it was.
Lot better than adding another device or opening on the aircraft.

Scott,I don`t know about the ones you refer to but I
have heard of useing unites salvaged from school
buses.Also Great Planes Aircraft sells a neat strobe
kit for about $30.One needs to come up with a mounting
box (Radio Shack) and a houseing for the bulb.This

--> Zenith-List message posted by: "Bima, Martin" <mbima@hydro.mb.ca>
Hello all,
I fitted my elevator skin last night and had to make an adjustment (pulled
the bottom skin aft about 8mm) for the trailing edges to meet correctly so
that I could trim off about 5mm of the bottom (not bent) edge as per the
manual.
I found the center of bend of the skin lined up correctly with the
centerline of the rib rather than the center line of the radius of the nose
as in the manual and drawings.
Everything worked out fine apart from this deviation. Anyone else have the
same problem? Could there possibly be an error in the manual and plans, or
did I just bend the skin in the wrong place?
Thanks and have a great new year!!!

Hello Zed,
The oil tank holds OK in the bottom with the oil hose, maybe because if
the size and wall thickness, we made an aluminum "omega" clamp for the
neck and hold it with bolts, it can be unscrewed easy if the tank has
to be removed, we put a piece of rubber betwen the clamp and the neck.
Results are great, hope to have it flying Jan or Feb.
Happy New Year to All!

ERROR ??? in a ZAC manual ???? Ya, like it will be a new year tomorrow... You
have probably got the bend a little off. I would not worry about it, it
sounds like you are close enough. Happy New Years to all you builders out there,

Hello Johann,
I think there is always some twist in the tail cone, depends in how
much offset is present, is dificult for the first time builder to be
aware of all this little details, in ours is dificult to notice the
twist.
What you should do is to put the rear spar channel 7F5-3SP of the fuse
prefectly horizontal, then try to offset a little the holes of the
rudder hindges to have the rudder perfectly vertical, depends in the
twist, in ours making the holes 2 mm to each side of CL was enough.
Same happens when you install the stabilizer, one side holes of the
angle supports will be a little higher than the other side (no one will
see both sides at the same time :-), just keep the stab level with the
rear spar channel.
Remember, acording to the photo manual, we squared the fuselage in the
luggage area with the piece of wood, the tail part should be squared by
the aluminum pieces 7F1-3 and 7F1-4.
I dont think that your fuse is to twisted to be a problem, only if
offsetting the holes doesnt help with the squared tail surfaces, then
check the amount of twist in the tail section (degress or distance off
vertical) and ask advise to ZAC... maybe in some cases, is needed to
make "offset" hindges 7F4-1 & 2 for the rudder, but I dont think any
fusselage will end that twisted...
Happy New Year to you, your Family and ALL in the LIST!

Thanks Gary,
This should be the type of aswer we should recieve from the Aeroflash
people, and also should be in the instruction paper...
How long should we make them work every time... we have a start
booster box from JC Whitney (the one that has the cables in the side) I
can make them work mean time the wings are in storage, looks great
inside the shop with rock music :-)
Thanks once more for the advice.
Saludos
Gary Gower
PS. The ones still in the box, should recieve the same 6 month
treatment? Do you advice to make a fake instaltion to make them work
twice a year? Not a dificult thing to do in a plyboard with dates of
running marked in it...

The main thing will be to check/test one and see how far is visible...
some units are not powerfull enough to be visible during day light when
airborne.

I experienced twist caused by the top skin not being
congruent about the centerline of the skin. I caught
this in the cleco stage. I layed out another skin and
made sure it was exact. the twist can be due to any of
the skins ,sides not being exactly the same, top or
bottom skin not congruent, or the ends not properly in
line. Once it is rivited it is extremely stout axially
and a small ammount can be compensated for by rudder
hinge placement and horizontal stab bracket
adjustment. Level the fuse at the rear wing attach
points and drop a plumb bob from the top rudder hinge
to see where you're at, if the hinges wont attach
safely to the longerons and maintain a purpendicular
relationship to the wing then look closely at the
skins.
hope this helps.

I believe the FAA has a specification for luminance levels for these (I read
it somewhere once). I'm certain they don't need to be TSO'd but you would
have to meet the specification (which might be described in the TSO)...

Hello, folks
There is some info on this subject in the Whelen catalog, page 3:
http://www.whelen.com/pb/11015.pdf
Here is an extract:
---
ANTI-COLLISION and POSITION LIGHT
REQUIREMENTS, LOCATIONS,
& DISTRIBUTION PATTERNS
All aircraft must have an approved anti-collision light and position
light system for nighttime operations. The position lights consist of an
Aviation Red on the left side, an Aviation Green on the right, and an
Aviation White tail-light (REF. FAR 23.1389).
The anti-collision lighting system is required under FAR PART
91.205(c). There are different requirements affecting different aircraft.
These aircraft are categorized by the date of application for type certificate.
Home built aircraft are determined by the date of issuance of
the Experimental Operating Limitations. The different categories are
as follows:
...
Aircraft for which type certificate was applied for after
July 18, 1977:
These anti-collision systems must produce a minimum of 400 effective
candela in Aviation Red or White (REF. FAR 23.1397), 360 around
the aircrafts vertical axis, 75 above and below the horizontal plane
(REF. FAR 23.1401).
*The position lights must be wired independently of anti-collision lights.

Maybe this will work!, wire a second wire via a 24volt bulb, when the panel has
juice to it, reduced power will go the strobe unit slowly charging the caps
.
So the normal circuit would be in series via the 24 volt buld and when the strobe
switch is turned on it would be in parallal .
Why a light globe it is just for resistance and cheap.
Untried, but as the strobe manufactures have poorly designed products it may be
worth a go.
If I remember Jim Weir published a strobe design a few years ago .
A few years ago there was a stolen formula a huge amount of pc board manufactures
were caught with the faulty caps, maybe the same capacitors?
You can read a little about it here in adobe pdf file.
