What is so great about this list . . ..
Even when a person offers a seemingly minor contribution to safety . .
like the use of magnets to catch screwdrivers, vice-grips, and steel screws that
are used in Yak52 etc. . .
(And obviously a magnet doesn't catch plastic or ally (alloy) .. thank you for
helping me with that. . . )
This list is so great because you can be heckled from each and every corner of
the world!
If we're going to think about this problem truthfully, maybe a committee is needed
to collect and evaluate ALL the ideas.
The "Drain" hole in the fuselage
The "pushrod" control tubes
The "cowmagnet protocol of 2003"
The "FOMBARS (Fabric Or Mesh Bulkhead Access Restriction System)"
The "Clear lexan inspection panel cover referendum of 2003"
The "great zues fastener to remove the inspection panel quickly design model of
Arizona"
The "Lets try all of them approach"
The "Lets try none of them approach"
The "Clean pockets and flight suits approach" . . no . . scratch that one . .
.
The "Clean pockets and wear a flight suit only if you want to approach"
Ahh. What the hell. Why waste our time ..
The FAA will figure it out for us

Good point. That is what makes a gently used battery last longer than one
that is abused. The effect is minimal unless you run one cell completely
dead. In that case that cell is reverse charged and it's life is
significantly shortened.
There are two basic strategies for charging batteries: constant voltage and
constant current. Most simple and inexpensive chargers for lead-acid
batteries are constant voltage. So is your plane. Battery shops sometimes
have constant current chargers (the batteries are all in series and the
charger increases the voltage to whatever it takes to get the 2 amps or
whatever it is set at).
I know some batteries have very intricate charging instructions (NiCads in a
King Air for example). The airplane electrical system can't possibly jump
through all of the hoops that the mechanic is expected to (admittedly the
$4000 ground charger does this automatically). This may be why NiCads don't
last long when used in real life applications like airplanes.
It seems to me the battery engineer's job is to design a battery suitable
for the conditions in the plane, rather dictating a lot of impractical
charging or ground servicing requirements. The great advantage of an
experimental plane is that you can use what works instead of buying the bill
of goods that Wichita wants to sell you.

Hi Gang,
Still out flying around on the B-24 and B-17. Presently in Lancaster S.C. where
the FBO is letting me use his computer. On our way to Camden next.
Just pick up a rumor that the TSA sent a number of jet Warbird owners that their
airplanes were grounded until they got clearance from the TSA. Don't ask me
where the hell they have the authority to do so. It seem this message was sent
via FAX and not a letter. Something don't sound right here.
Anyway has anyone else heard this?

Yes this is true. After 9/11 there was an FDC NOTAM 2/5167 which
proclaimed that instruction and/or proficiency flight in aircraft
weighing more than 12,500 lbs or turbojet powered aircraft was
prohibited. In order to fly, we had to apply for a waiver from the FAA
which made you fill out a form stating the steps taken to secure the
aircraft and how you were going to screen passengers etc etc. Us warbird
owners were allowed to apply for a blanket waiver. Now the TSA has sent
out a fax to all of us requesting that we re-submit the information. I
did it the same day then received a call from a nice lady at the TSA.
She thanked me for my prompt response and said my new waiver was being
sent out....I haven't received anything yet. There was never any
language however stating that we were grounded.

Correction, the fax said that we had 30 days to re-apply. If they don't
receive the application within 30 days then the original blanket waiver
will be cancelled.

--> Yak-List message posted by: "Jorgen Nielsen @ Mweb" <jorgen.nielsen@mweb.co.za>
Lead acid type batteries want to be charged using constant voltage. As the
battery is charged, the internal voltage increases, thereby automatically
reducing the current that flows into it. Nicads prefer a constant current,
but unless using a sophisticated charger (like the $4000 one mentioned)one
cannot easily control the charge. You can build a simple circuit using an
adjustable voltage regulator to create a homebrew constant current charger
for ground use, but this would be limited to relatively small currents.
Most nicads are ruined through overcharging, so unless flying every day
rather go for a small current.
A trick I have used previously (on a seldom used motorcycle & on 2 boats) is
to fit a fused DC plug with cover somewhere convenient, then made up a long
charging lead connected to low capacity charger. When not in use, simply
plug it in and keep it plugged in, then its always ready for use. Should
work fine on a plane. Just keep the charging current down so you don't fry
the battery, or fit a regulator in the circuit so that as the battery
reaches charge, the current reduces to float. If you dont have power in the
hangar use a solar panel or 2 in series for 24V.
This is the same problem yachties have, good info on the web.
Hella make a great DC plug that is waterproof with a positive locking
action, and can handle around 10A. I think its designed for rally style fog
lights, and works really well for this type of application.
When choosing a battery work out the total drain (e.g. xsponder + comm) in
Amp hours, multiply by how many hours you want, double it and thats what
size battery you need. E.g. 1.5AH X 3 hours + 4.5AH, you need a 9AH
battery. You will never get all 9AH out of it and shouldn't discharge
totally anyway, plus you get a bit of reserve.

The aircraft chargers use two methods constant current till the battery reaches
1.36 volts per cell than switches to pulse charge for toping charge. The other
method is pulse charge of varying duty cycle. The NiCad has to be temperature
monitored as if they have a shorted cell they can reach thermal overload and
can burn there way out of the aircraft. I have seen several batteries short cells
toward the end of charge on a monitored Christie charger and fill the shop
with acrid smoke.
The charge current of a lead acid battery is limited by the difference of potential
between the regulated voltage and the battery voltage with the series resistance
being the leads and battery internal resistance. As the battery voltage
reaches end of charge the current is reduced because the difference of potential
is reduced

Two bladed V530 props run from NEW $4500 to used $3000 if you can find them.
Finding them is the challenge, many have been chewed up this year with gear

The "hot rock on the block" is the new and improved MTV-9-B-C/CL260-29,
released 8/20/2003. I think I remember Larry Schlasinger of MT quoting me
12k for the new -29. Larry is taking in trades (MTV-3 and MTV-9-with -27
blades) and not giving us much for a trade. I know a MTV-9-260 -27 blades
that is going in. Larry's e-mail mtprop@hotmail.com
Better yet...if you are interested in an MTV-3-250 with brand new overhauls
(4/03), all AD's cw. I have two that I would sell for $8,500 obo each to
allow me to get the new -29 (and swipe some of Larry's resale profit). I
need all the penetration I can get... Vertical for aerobatics, potty minds.
