Is there any conventionall wisdom (aka "been there, done that") about
wing struts used by certified aircraft which are suitable for the Piet?
Some model of a Piper? Cessna? T-craft? etc.
If so, I'd appreciate the details . . . ALL the details.

Dick,
I picked up old , rear J3 Cub struts at a local airport. Most old hangers
have them in the rafters. Visually , they look to scale. And you lop off
about a foot from each end anyway, so you can inspect the interior. Mine
still were damp with preserving oil.

Ah, yes...the good ol' days, when I didn't have brakes (last spring), and
things were much simpler. Now I have quite a few more things to check on
pre-flight, items that might fail (if it ain't there, it can't fail), and I have
to carry this extra 6 or 7 pounds around on each flight. I use the brakes for
maybe 30 or 40 seconds on each flight - mag drop / run - up, and a little
stab here and there to taxi...that's it. I never use them to slow down.
Therefore at first thought, it seems they are just not worth having, especially
after
having oporated my plane without brakes for about 30 hours. It handled very
well with the tail skid, and no brakes...as long as it was on the grass. Taxi
on the hard surface, and it was like a fish out of water...limited or no
response to rudder input, and a small breeze on the tail would have its way.
One of the squawks I had to take care of, was a leaking master cylinder,
so I had to remove all the stuff under the front seat, and while I was in
there, I cleaned, sanded, cleaned, sanded, cleaned and re-varnished the front pit.
On the plus side, the oporation of the heel pedals, and break control is
very good, and fairly comfortable.
In conclusion, if you're going to do any cross country flying, where hard
surface oporation is inevitable, brakes and a tailwheel is are required
equipment, but they sure are a pain.

p.s. I have some really good digital pictures of my set up. If anyone wants
to see them, just e-mail me direct, and I'll e-mail you the pictures.

Group,
I just sent six pictures to Matronics Photo Share, but I've never done it
before, so we'll see if I did it right. I got quite a few requests, so I did it
this way. The pictures of the final assembly, as it is in the plane, is still
in my camara, and my camara is still in my plane...I knew I forgot something
when I left the airport Thursday !! I'll get some detailed dimensions the
next time I'm out there, and try the photo share again.

<< OUTSTANDING!! I'm printing this out and keeping it with my contruction
log & notes. Who is Mike Shuck? >>
Mike is based at Benton Airport, and we do some hanger talk at least once a
week. He just completed his RV6A, and has been flying it a lot. He'll be at
Oshkosh this year. Every time he sends me the stuff on airfoils, via e-mail,
for some reason my computer doesn't accept the graphic stuff, and the info is
very limited. Probably the settings I have, but I don't know how to alter
them. I downloaded what Ken sent, but it took 19 minutes...it worked, but no
graphics. I finally got to read his article. I just hope he doesn't start a
trend to change the Pietenpol Airfoil. Mike is a great 'Airplane type guy', with
a real sense of humor, very interested in aerodynamics (he also did an in
depth analysis of the Tailwind airfoil), and has been there when I needed a hand.
He has a web site on Yahoo, but you have to sign up with Yahoo to access it.
The web address is: http://groups.yahoo.com/group/airfoil/files/
For his day job, he is a Doctor.

Subject: | Spar/Strut fitting |
--> Pietenpol-List message posted by: "Kirk Huizenga" <Kirk.Huizenga@moundsviewschools.org>
During the rebuild of my Piet I have found a few of the holes in the fitting (that
wraps around the spar, mid wing, and connects to the wing strut) are slightly
elongated or mishaped. I am planning on replacing the fitting, adding a phenolic
bushing in the spar and getting new hardware -- my question is whether
the fittings must have the top piece welded that connects the two straps together
into one piece. It would be much easier to just have two seperate pieces,
one on each side of the spar and not connect them.
Thanks for any input
Kirk

Kirk,
You wanted some input so here goes.
I beveled the edges of the 1 inch top piece and the two side pieces (straps)
by tilting the table 45 degrees on a 1 inch belt sander. I cut 1 inch square
tubing from ACE hardware into four 7 inch pieces and drilled the 1/4 inch
holes for the bottom three holes and bolted the two pieces to the square
tube. I put a 1/4" bolt and nut in the hole next to the top and tightened it
just enough to hold the 1" top piece in place. It took a MIG welder less
than10 minutes to weld the four. This is really a easy procedure and I
would bet some other Piet builder even has a better procedure. Think about
how much more resistance to elongated holes exists when this fitting is one
piece as designed.

Need some advice on what kind of exhaust to use? I have a 110hp corvair and
was going to use the same as Bernie Pietenpol did on his first one that come
out straight out on the sides or the one I seen at Brodhead Last original that
he ran out the bottom? Any help, I know it is a personal preference. But just
wanted to know if the would be a performance approvement. Thanks Dave
