Corky,
I agree with Chuck. The plans call for the correct rudder horn size. We
have about 500hrs on our Piet and it is a blast to slip. There is
plenty of rudder to get it to come down at a 30 degree angle. And more
rudder is available for landing than my skill level will allow me to
use. The old adage about sticking to the plans makes sense here.

Mike,
Sorry I missed your request for pictures, I missed a few messages that day.
Here are the pictures DJ took, and the link below shows pictures I took on a
COLD (-3*F) Indiana morning (when you are from TX, that is WAY too cold).

I'm working (OK I still need to start) on a page that will have all of my
"trip stories" and pictures, maybe I can get that done tonight. It was a
great trip, and I met some of the nicest people you could ever meet.
I spent nearly 4hrs in my new plane yesterday, and I'm going back this
afternoon to give some rides to friends. I'm having a great time if you
can't tell!

Corky and Nathan,
Nathan commented that the plans set up felt like an abnormal amount of
movement. I'm curious - What did he mean by this ? During the landing and
take off, it is completely normal to be dancing on the rudder. For the rudder,
it seems he meant it needed more deflection of the control surface with the
same amount of movement of the rudder bar. This is what you will get, if you
move the holes on the horn from 5" outboard of the hinge, to 3 1/2 to 4"
outboard of the hinge. A change in distance of 1 to 1 1/2 on the rudder horn,
is a considerable amount. The trade off will be a very sensitive rudder in
cruise flight. You'll be constantly chasing the ball back and forth. I
believe you have rudder pedals, as opposed to the rudder bar. Do you already
have
the point on the rudder pedal located ? You can also alter this ratio with
that attach point. Before you drill the holes, I would suggest you somehow
clamp the cables in the anticipated position, and carefully try it out while
sitting in the cockpit. Just remember to place the rudder stops to keep the
rudder from touching the flippers (elevators).
My own experience with well over 200 hours in my Piet, is that I have
NEVER ran out of rudder authority. When entering a turn, I lead the turn with
a tiny bit of rudder, which helps cooridinate the turn. Adverse Yaw is a way
of life with vintage designs. Even in my cross country flights, it is
seldom that I have to make landings in severe crosswinds. There is almost always
a place to put 'er down with less than a 10 kt crosswind component. If need
be, I land a little bit diagonally on the runway, while keeping the upwind
wing low, and touching down on the upwind wheel. The rule of thumb for maximum
crosswind component is 25% of the stall speed. If it is more than a 10 kt
crosswind component, you don't have any business out there in those
conditions.
As for pitch control, the power setting is an effective pitch control due to
the penduleum effect. This becomes even more pronounced, with the longer
cabane struts.
In my opinion, I have found harmony with all the flight control
surfaces, and wouldn't change a thing. I did about 6 or 8 landings this evening,
with about 15 to 18 down the runway. By dragging the tail in before the mains
touch, is the only way I can get a decent full stall landing. I didn't have
to do that when I just had a tail SKID back there. With a tail wheel back
there, it raises the tail to a point where the wing is not done flying yet, in
the 3 point attitude, and a couple of bounces are in order. In windy
crosswind conditions, a wheel landing is preferred. I have also found a wheel
landing is preferred when I have a passenger on board, or when landing on a hard
surface runway.

I want to make up and airspeed indicator to mount out on the wing
strut. The body of the unit is no big deal, but I can't find a spring.
Do any of you have any suggestions. Here is a photo of what I want to
do.

It kind of looks like a farm implement spring.

Not sure if it is want you want, see what others say, but Piano wire that
you get in Hobby stores can be bent in many configurations and maintain its
springy-ness...

There is information available on the web for making your own springs. Do a Google
search
for "making springs" and you will come up with several tutorials. A quick glance
through one
showed winding music wire around a mandrel and then stress relieving it in a 500
deg oven for
an hour or so.

I agree with Doug. Make up your own using
1/16 or 3/32 wire. 3 wraps around a 1"
mandrel and make the ends however you like.

Craig,
A few months ago, I posted a detailed description, complete with all the
measurements, of the Johnson Airspeed indicator. I thought I saved it on my
computer, but I can't find it. I think if you would search the archives, you will
find it there.

The vane-type airspeed indicator in the picture is a DeHavilland type that
was used on Gypsy Moths and Tiger Moths.
Using one of these as a pattern, I made a copy for my Pietenpol years ago
and marked the scale with reference to the ASI in the cockpit. I had
difficulty matching the wire type and diameter and used drag/antidrag wire
from a J-3 Cub wing to make the spring. It is not as hard as piano wire, but
is sufficiently springy for the purpose. Since it was a bit stiffer
(slightly larger diameter) than the wire on the DH "instrument", I had to
make a larger vane to get enough travel over the scale. Marks (no numbers)
were initially placed on the scale and the position of the pointer was noted
during flight, using these marks for reference. Then the scale marking was
done, complete with numbers similar to those in the photo.
Today, it is mounted on the left front interplane strut of my Sperry
Messenger replica and has proved to be a reliable device, always in close
agreement with the ASI on the instrument panel.
Cheers,
Graham Hansen (Pietenpol CF-AUN in Alberta, Canada)
