Speaking of shock cord, I am up in Poplar Grove this weekend replacing mine
. I need to add somes sort of "dams" onto the top of the axle, in order to
keep the bungees from working their way too close to the wood legs and gett
ing pinched. I was down to 50% worn through on one side, only after about
10 hours of operation! Yikes!

While on the subject of bungee chord, I have a mate who is ordering a pile
of it
o im going to buy mine now. Im building the straight axle and am wondering

Hi Scott,

I fabricated the elevator and rudder control horns over the past couple of
days
to the plans. Fun work and a good test of my newly acquired gas welding sk
ills.
I have a question for those of you who built them to the plans. After zinc
chromating them it occurred to me that there will be a large area of unprot

metal inside the horn since the forward end that attaches to the wooden spa
r of
the control surface is open ("butterflied" if you will to attach to the spa
r).
What can be done to protect this bare metal? I thought of spraying linsee
d oil
or fluid film into the opening and sloshing it around. I'm not keen on see
ing
corrosion on these horns which are so visible on the completed aircraft (no
t to
mention they are a requirement for controlled flight!).

Subject: | Suspension Travel - FlyBaby style gear |
A friend is looking at a Piet with a FlyBaby style gear, which has no
suspension travel. My first inclination is that I don't like this, but
I can't really say why...just because it is different I suppose. It
seems to be working fine for the FlyBaby guys, so maybe it is OK. This
plane has 800 tires that will provide some cushion when the tire
pressure is right.
What are everyone's thoughts on having no suspension travel other than
tires? Are there any reasons this is bad?
Thanks!

Maybe I'm slow, but it took me a couple hours to catch on to that knot, but
as it turns out rib stitching was very enjoyable and therapeutic. Only pro

Depends on how smoothly you can land and how smooth the landing surface is.
Jack Phillips says he had a cub and covered the bungees with tape and never
noticed that the tape had moved, indicating that the bungees had never
moved. I'm going to put a "no suspension travel" wooden gear on my Piet
similar to the one for sale (green and white) recently shown on the list. C

A couple of useless comments that I probably should just keep to myself, but for
some reason, I don't seem to be able to:
1. @ Steve: 800 tires should provide quite a cushion. Most aircraft only have
2 or 3, so the extra 797 tires should help spread the load - as you said, provided
the tire pressure is right.
" This plane has 800 tires that will provide some cushion when the tire pressure
is right."
2. @ Jeff: You have some big friends. Funny that they would all have Flybabys.
" I have 3 friends with Flybabys wieghing between 650 and 750..."

Yes, John, really. It was quiet funny.
Of course, given his chronic intake of cigarette smoke for the past 40 years, at
the rate of approximately one pack per day, the 3 second surprise from applying
heat to that control horn is the least of his worries. He's in spectacular
shape, BTW. In better condition than the vast majority of participants on this
list. Works hard, plays hard and has a ball. He's in his late 50s or early
60s at this point.
Point is: weld before you paint. A simple point, easy mistake, and easy to avoid.
You know what us safety pro's say: safety sucks, press your luck.

OK Wayne,I was right.
But, I was not smart enough to argue my point of view. So I got me a Big Gun. Dr
Dave Rogers is on the Beechcraft Bonanza list and has a good track record of
teaching us Luddites about aerodynamics. He knows a little about this since he
teaches aerodynamics at a small school in Annapolis, Maryland, that school has
as something to do with ships. Some of their graduates fly off of very short
(though paved) moving airstrips.
Dave is able to take some highfalutin science talk and dumb it down enough so that
even a Marine can understand or better an Army Grunt, (BTW a blade antenna,
mounted properly is much more aerodynamic than a rod antenna. He has me convinced
that about the only thing aerodynamically worse than a round pole is maybe
a square block)
Below is the original message I sent to him:
Dr. Dave, in a discussion with a fellow pilot. I made the following statement:
"In layman's terms, the reason a plane gets more "Twitchy" with an aft CG is the
shortened distance between the CG (moved aft) and the elevator. Move the CG
forward and the plane becomes more stable. When the CG is too far forward, the
plane becomes so stable that the required response may be too slow or not possible.
IE too far forward a CG and you can't get a good flare when required."
The other pilot said: "I thought the reason for the increased sensitivity was due
to the Center of Gravity becoming closer to the wing's Center of Pressure."
Which is correct?
Or is it like Bernoullis sucking or Coandas blowing. Luckily the end effect is
the same.
I think I got my idea from the Gleim Pilot handbook recently studied for an FAA
test.
Blue Skies,

This is a reasonable layman's description.
Technically, there is a point as the CG moves aft at which the stability becomes
neutral. That point is called the neutral point (stick fixed, stick free, with/without
power as the case my be). If the CG is aft of the neutral point, then the aircraft
is unstable.
When the CG is too far forward a number of things may occur examples are: (a) there
is not
enough elevator power to flare the aircraft for a full stall landing; (b) the
stick force is too large; (c) the stick force gradient is too large.
There is a small discussion of the forward CG question on the Technical Flying
website.
>
>The other pilot said: "I thought the reason for the increased sensitivity was

This is wrong. Technically this is associated with the balance of the aircraft
and
not the stability.
Simply put, an aircraft must be both balanced and stable (modern tactical fighters
are an exception to the stability requirement). In a conventional configuration,
i.e., with a horizontal tail, it is balance that requires the horizontal tail with
typically a down force on the tail. It is the stability requirement that limits
the aft movement of the CG. Control requirements determine the forward CG limit.

BEFORE I COULD GLOAT HE ANSWERED ANOTHER BONANZA OWNERS COMMENT, BELOW IS HIS EDITED
COMMENT:
A reasonable simplified explanation. Improved:
1. Stability (tendency for the aircraft to return to the trimmed speed when displaced
a small amount from the initial trimmed speed.)
2. Sensitivity to controls (the tendency for the pitch to change a lot, vs a little,
with a given movement of the yoke).
Other Pilot comment: 3. Moving the CG forward tends to make the aircraft more
stable. If the CG
is moved too far forward control issues result, e.g. stick force becomes
too large.
DAVE'S Answer: Moving the CG toward the elevator makes the aircraft less stable
and makes it more sensitive to elevator inputs.
for the same elevator force a shortened lever are would result in LESS moment
to pitch the aircraft.

So I was right, but I sure did not understand why until he told me why.
Blue Skies,
Steve D
His WEBSITE (listed Below) has Beech Bonanza centered articles under Technical
Flying, but there is a lot of generic aviation information. I do not do math in
public and it makes my ears bleed if I don't understand it, I prefer to just
believe.

Wow. That is quite a few hours of Pietenpol flying time for two years - definitely
above average - but when you take into consideration the fact that you only
had access to the plane for about half of the two years, that's really something.
And did you read that, Gary? Kevin says he will be building ribs tonight... that's
ribs, with an 's'... as in plural, as in more than one. What a show-off.

@Jim - Dunno how much we'll fly before Brodhead. Depends on the peace dividend.
If there's enough peace we'll fly our butts numb and try for Brodhead again
in '12. If there's not enough peace we'll see you guys in '13. :)
@Bill - Helps we're in Texas. We get to fly year-round, though it does get "cold"
(sweater weather for you) for a few weeks.
Ya know, Gary's thinking about a Flitzer project himself. With two wings I figure
it'll be 70-80 years before he can catch me on that one.

Cute, aren't they? I went through the Fly-Baby and the Corby Starlet before I
found the Flitzer. It really caught me emotionally. I've learned that if I'm
going to spend 16 years on something I'd better love it pretty intensely.
I'll say this: the quicker you finish your Piet the quicker you can start on your
Flitzer. I personally got distracted by a couple of other projects during
the Piet and all they did was add time to, and take resources away from, the real
goal: the Pietenpol.

I believe that the second answer is correct for 2 reasons.
1. Let's say that the distance from the cg to the elevator is 100 inches. The
recommended cg range is 12 to 20 inches. That's a maximum difference of 8% in
the "lever arm" from max forward to max aft. Not likely to make a distinguishable
difference.
2. If the cg moves aft of the center of lift, the aircraft becomes unstable, not
unlike throwing an arrow backwards. Build a paper airplane and put paper clips
on the tail and see how well it flies if you want a very simple demo. In
order to achieve extremes in maneuverability, military fighters F-16 and after
deliberately do just that. They then must use computer control to keep the
pointy end first since human reflexes are incapable of reacting fast and accurately
enough. If I recall correctly, the F-16 has two primary and one battery
backup flight control computers and if they all fail, a nylon approach is recommended
and probably mandatory.
There's also a synapse that fires that says the center of lift on a wing is not
static and that it changes with angle of attack as airspeed and g loading change..
That means that the designer must insure that the most forward center of
lift must remain aft of the most aft cg.

Subject: | Retractable sliding step |
Members:
Here are some photos I made of my step which I created last year. The key here
is light wall tubing slid inside another tube. The buttons are called step buttons
found in aluminum canes or crutches. They will allow for my step to slide
out and lock into the correct 6" length. Then push the button in and they slide
back into the sleeve. I placed this set-up as as far back as I could under
my seat. Used small pieces of ash bolted through my 1/4" thick floor!
So now... flame away as I added MORE weight to the rear of the fuse! I will have
the nicest easy to get into..outside control horned..looking Pietenpol "brick"
in the country! However, I am keeping it to plans!
