Thanks for the cool pics Walt! For some reason, every time I see this picture
it makes me want to get out and fly! It's of Andrew King giving a ride in my
Piet last year at Brodhead. Problem is, it looks like nobody is flying!

Hi Walt
I noticed on the large pic, a very large gap between the horiz stabs and
elevators. If you haven't already done it, try sealing that gap with a
piece of duct tape. You might be surprised at how much it changes
flying and ability to get tail up on takeoff.
I realize there might be clear sealer already or you may have already
tried this.
It's just a thought.

Subject: | Newbie with questions |
Please let me introduce myself. My name is Jim Birke. I am a member of the Ira
G. Ross Aerospace Museum in Niagara Falls NY. We are about the preservation of
the history of aviation in western NY. Such names as Bell, Curtiss, Fleet, Consolidated,
Etc. We are also in possession of a partially completed air camper
which was to us donated by the wife of the gentleman who started the project
but passed away a few years ago. The museum has asked a couple of us to see if
we could complete it. We have no plans to make it airworthy however, we are taking
great pains to carefully build it to the original plans and make a show
piece of it. I have been given the position of the go-to guy and, if you don't
mind, I'll be regaling you folks with questions from time to time.
The 1st question is in two parts: A and B
The flying struts have been completed and the attachment points have been installed
on the fuselage the attachment brackets on the wing spars are not installed.
The ribs are glued to the spars and we have temporary drag and anti-drag "wires"
made of twine installed to keep the wing from racking if we have to move
it. BTW it's a three piece wing. The center section is finished and we are working
on the LH wing.
Part A. It looks like, in order to install the flying strut brackets on the wings
and establish a dihedral of approximately 1 deg. at the same time, we have
to mount the wing on the plane, get the dihedral set up, and let the flying struts
determine the placement of the brackets on the wing. I know there are dimensions
on the plans but, since there are no adjustments anywhere, I am not comfortable
relying on them. Am I correct with this train of thought?
Part B. In order to mount the wing, we have to mount the center section. In all
the photos I've seen of finished Piets, There are two diagonal braces that appear
to be running from the top of the forward center section struts forward to
a point just above the firewall. These appear to be absolutely necessary to
keep the center section in place fore and aft. The upper engine mount plates on
our plane have what appears to be an addition to them to attach the lower end
of the diagonal braces. (See attached photo.) This is not called out on the
original plans nor are the diagonal braces. I need to find out how the diagonal
braces are constructed and the dimensions of them and the method of attaching
them to the upper end of the center section struts.
I will be grateful for any and all help You can provide.
Thanks, Jim B.

Jim:
Part A:
If the struts are the correct length, your method may work. The way it
is done is the wings, with the fitting installed in the correct
position, are installed on the airplane, and the struts are built to the
length needed. It is not easy to imagine how he built the struts first.
The one degree dihedral is not in the plans (neither is the 3-piece
wing), it is added by most folks for flying stability. If you are
building for display, you could make the wing flat so that it looks more
like the original one-piece wing.
Part B:
The diagonal strut you refer to is an after-market modification. The
original plans have an X of wires between the cabane struts to hold the
center section stable fore and aft. Most people leave off those wires
in favor of the diagonal strut to make front cockpit access easier. If
your airplane is built for them, the top engine mount fittings will have
ears sticking up for that strut to attach to. If not, it would be more
original and easier anyway to install the cables.
I am in Buffalo frequently with my job, and would love to see your
project the next time I am there.

Dick,
I haven't had a problem with that control. Maybe I'd see a difference
if I did do the gap seal. But it's not like the pitch
control/response is sluggish.
But thanks for the tip

Thanks Gene. He apparently built the flying struts to the dimensions on the plans.
We have a Pietenpol drawing showing the construction of the wing center section
and the treatment of the butt ends of the outer wings. It has a later date
on it which I can't recall at the moment. I noticed the right side cross wires
on the plans, but I'd say the diagonal braces would be much more effective.
You have my email address. I will be more than happy to show you the Piet when
you're in town. Give me a days notice. You'll also get to see the resurrection
of a 1917 Curtiss JN-4 that we're working on.

Hi again Walt
It's worth a try. When I did mine, I gained 2 mph, tail was much easier
and faster to get up on T.O. roll, and control response much better on
approach at slow speed.
