Yes, I will get an Odyssey battery, guys.
Yesterday I wrote to Rex, in a direct email, that Norway is a small country and
it is not easy to find special items. As an example, I had to go to Sweden to
find 3130 steel pipes.
But, this morning, I typed Odyssey in a Norwegian search engine and yes, they are
here, in Oslo! So, I picked the phone, called them and, after explaining my
problem, they recommended the PC 680 model, that is pretty close to your PC 625,
Steve.
Thanks again, everyone and especially Rex that has sent me direct a lot of info
about batteries and Odyssey. What a great list!
So, I am left with one question, guys: In your opinion, what are the pros and cons
to have the CG* within the limits but rather forward of the middle point?
Thanks in advance,
Michel

The time is approaching when we will mount the wings and start connecting
things up. As space is
limited in our hangar we will probably have to fold the wings again fairly
soon after putting them on.
Over a year ago I printed off a check list from Kurt S. for wing folding.
(Pause here to mention what
a great list this is because of things like Kurt's check list.)
Kurt's list refers to a couple of devices we do not have. Here are the
points.. (and keep in mind we have never wing-folded a Kitfox or seen one
wingfolded)...
13. Install wing holdback fitting to tail
14. Install wing leading edge support rod.
15. Install flaperon support.
Question is, where do we get these 3 devices? Are they so simple that we
just make them?
Are there any pics out there? Thank you very much in advance.

Rick,
I haven't yet flown mine yet, but there are others on the list that have the same
unit that I have. I've got Elbie's RiteAngle IIIb unit. It's VERY well made.
Support has been exemplary. John King I know has one on his model 6.
As for the numbers...Try getting those from John. His model 6 should be pretty
close to your airplane. His engine is lighter (912 vs. your Soob), but regardless,
the AOA numbers should be fairly close.
RonSeries 6...still building.

I will chime in on your CG question. I have experimented with mine all over
the range. My CG is currently slightly forward of center area. This position
gives good stable flight characteristics and especially a pleasant and
predictable glide while in the flair. For a while I had the CG almost to the
rear limit. Control was VERY crisp, but, I really had to be on the ball with
the throttle during the flair because the aircraft exhibited a tendency to
suddenly drop out. Not a good thing for short field operations as it would
extend the landing by quite a margin. I would begin at that point...after
you wring out the bird then you can begin playing with a 5 lb. chunk of
lead. Move it around a bit to see how the airplane feels.

| Subject: | any Kitfox-builders near Geneve? |
--> Kitfox-List message posted by: "Koen Van de Kerckhove" <nestofdragons@hotmail.com>
Hallo,
I am visiting Geneve next monday. Will be busy before noon, but will be free the
afternoon and evening. I hope ... and pray ... to be able to visit something
that is related to airplanes. But, no museum of airplanes. Grrr. So, now I am
searching for persons who lives near Geneve and who are building a airplane.
Somebody told me that there are Kitfox-builders near Geneve. Can I visit you and
your airplane that evening, pleeeeaaaase?
Who am I? I am Koen Van de Kerckhove, the webmaster of the "Nest of Dragons" site.
Site is dedicated to the design and history of weird designs. Also about low
budget airplanes. Each time I see some kind of construction I get a wave of
inspiration to sketch some new concepts myself. I am wondering what kind of wave
seeing a Kitfox-airplane ... and builder will give me.
Keep that brain spawning wings,
Koen

Kerry, for routine folding while working on the airplane you don't really
need the leading edge support rods. Those are mainly for transport. It's a
little easier on the pivot points if you remove most of the gas though. The
flaperon supports can be most anything you have around. I just use bungies
with some padding between the flaperons and rudder. For transport I'd come
up with something a bit more substantial. The wing holdback brackets at the
tail should have come with the airplane kit. You sure you don't have them?

Now tell me, if while flying, I tossed that 5 lb. ball of lead into the air,
would it be affecting the CG or not? ;-)

Here's a side pic of my IV's tail that shows the wing
holdback struts (blue). They should be in your kit.
http://www.foxflier.com/kitfox/Trailer/HPIM0253.jpg
The flaperons really only need to be kept from
damaging the vert stab/rudder. I use the same setup
on the vert stab as that on my horiz. stab to secure
the elevator. 1" PVC pipes covered with pipe
insulation as a cushion with a 1/4" carriage bolt and
wing nut at the back pulling the two ends together.
The pipe insulation keeps the flaperons away from the
stab/rudder and protects the paint.
The wing LE supports are shown here
http://www.foxflier.com/kitfox/Trailer/HPIM0250.jpg
I made'em out of EMT conduit. They've worked for
years...
Regards,
Ted

For hanger use, just put some towels or something to keep things from rubbing.
IMHO, you have other concerns when first folding the wings. 1. If you have
the room, I'd recommend raising the tail to a near in-flight position. That
way, when you pull the wing pins the wing will stay right where it is and not
swing back on it own weight. If you must leave the tailwheel on the ground,
get someone to help you on the first couple tries. When the wing starts back,
go real slow and watch the flapperons area around the turtledeck area. You
will have to move the flapperons very carefully to avoid banking them on the
turtledeck attach points. Go very slow and it will become apparent. Once you
get
past that hurdle, gentle move the flapperons straight up as you continue to
fold the wing back. Be careful during the first part. 2. If the tail wheel
is on the floor, CHOCK the front of the mains. The weight of the wing trying
to swing back while you hold it can cause the plane to roll forward. This
makes you lose control while you're trying to do things slowly. 3. Make sure
the
flapperon connect tubes (that you disconnected under the turtledeck) don't
get caught up in the flapperon horns when you start the fold. 4. Train your
helper at the wing tip to do absolutely nothing until you say so. I have
problems with the helper trying to swing the wing back too fast, sometimes they
want to lift up on the wing. All they have to do is stand there and keep the
wing from folding back while you make sure everything clears.

Also be careful not to kink the fuel lines or vent line near the pivot points.
As mentioned before on the list, you can't have much fuel in the tanks or it will
come out of the fillers when the wings are back and the tailwheel is on the
ground.

That's a good idea, Steve.
You see, when I bought my plane, I knew nothing about planes but I could see
that she was built by someone who knew his business and I didn't dare to
experiement anything. But now that I get warmer and even call myself a
half-builder ... :-) I might just do that and experiement with a lead ballast.
... and no, SteveZ, I won't toss it in the air! :-)

Rick,
I have the RiteAngle III AOA system installed on my Series 6. You have
to calibrate the system to your particular aircraft as configured.
There are five panel mounted LED's that display aircraft attitude up to
the time of stall (three green, one yellow and one red). It is up to
you to establish the airspeed for the various LED's. I chose to
calibrated mine so that the first Green LED comes on at an IAS of 60
mph. The other four LED's are calibrated for lesser airspeeds as you
approach stall. My Red LED comes on just prior to stall. I use this to
set up my landing approach speeds around the pattern all the way to
touch down . A good landing occurs when the Red LED comes on just
before stall when my wheels are a couple inches from the runway. Oh
yes, there is also a audio female voice in your head sets when the
Yellow LED (Warning, Warning, Warning) and the Red LED (Stall, Stall,
Stall) illuminates.
You have the ability to make the various LED's come on at any desired
airspeed, but they have to be a decreasing sequence of numbers. The
actual numbers I chose for my system are now at the airport, so they are
not now handy. If you want them please specify and I will get them for
you. later

Of course, Steve! I am more of a coward than a dare-devil, you know! :-)
Seriously, I have - of course - tested different CG in my flight simulator,
which I take with a big grain of salt! I am a coward but not a fool! :-)
And the flight simulator, with the CG at the foremost point of the tolerance
gives a plane that cannot make a three-point landing but that is much less
prone to ground loop. On take-off, the tail will come up very early but the
plane won't take off without me pulling the stick. In the air, it has less
tendency to stall from one wing or the other and "mush down" straight on
unpowered stall.
Is this what I can expect from the real plane? One element I don't have to
model a proper plane is the pitching moment. All airfoil definitions are with
lift, drag and pitch moment coeficients. I have worked out drag and lift for my
undercambered model 3 wing but I have no data about the pitch moment and I
don't know how different it is from e.g. a more conventional NACA profile.
Cheers,
Michel

Is anybody fimaliar with a product called "Kitlog Pro" ?
As The chapter president of EAA chapter 612 in Kansas City I received a free
down load of this product to give away as a door prise at our next meeting
and was just wondering exactly what it was and if it was a quality product.

By the name it sounds like a utility for keeping a builder's log. I did mine
manually via computer...but something to arrange all the test and photos
would have been nice too.

Kirk,
I have been using it for a few years, and I really like it. Easy to use as
a construction log, keeps track of what I've spent, has the forms built in
for registration and everything. I'd recommend it to anyone building!

John,
A bit confused. A normal state of mind for me lately. But I thought airspeed
had noting to do with the stall AOA. I mean I know the plane has to be
flying to stall, but I was told the stall always occurs at the same AOA
regardless of speed. On the other hand I have also read a heavier plane will
stall at a higher IAS than a light plane. Help me out here.
Rick

I was wondering if I might fabricate some vented caps with looong vertical
tubes; long enough that the ends would be higher than the tank and
therefore the fuel wouldn't run out. Do you think the caps would leak
anyway? Or would the resulting tank pressure force fuel out elsewhere? I
hate the thought of de-fueling every flight, as I intend to keep the
aircraft in a trailer with the wings folded.
