Hi Rick,
Did you lean the pilot's seat back on yours? I would do that if I had to do
over again. I did move the seat straight to the rear by 1/2" in., but that
doesn't help the aching legs and feet on those long trips. My longest leg
was 2 1/2 hours from Mt. Vernon IL back to Loensloe last summer. That was t
he end of that "Longest Day", 15 hours in a Pietenpol before the sun set.

It really is working out well Mike. As I said, I plagiarized what you
had already done. Putting the rear extension into the shelf area as yo
u did is a better way to go as it gives more support to the tank. That
area behind the front IP is wasted space anyways. I was just trying t
o simplify the tank construction. Until I actually did the fuel flow t
esting, I was afraid I would have to use ram air to pressurize the tan
k, but fortunately it wasn't necessary. I have taken off now with a fu
ll 18 gal tank and all works well, however that gives me 3 hrs flight
time with a 1/2 hour reserve. So far my longest flight has been 2-1/2
hours. As much as I like flying the Piet, I was ready to land and take
a break at 2-1/2 hours. When I used to hear people say 2 hours was
long enough in a Pietenpol I was wondering what is the problem? I f
ly over 3 hour legs in my TriPacer all the time with no problem. With
a Pietenpol is it lack of padding in an uncomfortable seat? The noise?
The wind buffet? For me its just like driving a motorcycle for a long
distance. Its the fact that you can never relax like you can in a car
, or a more modern enclosed cockpit aircraft. You have to fly it all t
he time. Not that I am complaining, its just a different kind of flyin
g. In all respects it is more enjoyable than flying the TriPacer, but
17 or 18 gallons of fuel is certainly enough.

Glad to hear your nose tank is working out Rick. Love my 17 gal
lon nose tank. No header tank, no muss, no lines running from a
center section tank (my center section is all baggage)

Vincent,
Here is what I did. My tank is 18 gal. I am only using
gravity feed to the carb, no fuel pump was required. When
I ran the fuel flow test, with the plane at about a 16 degr
ee angle of attack, there was plenty of head pressure. I don
=99t recall the actual figures, but it was way better th
an the 150% of max power fuel consumption required by the FAR.
The useable fuel was also almost the full 18 gallons except f
or a few ounces. The last fuel flow test was actually done wit
h 48 ounces of fuel and the fuel flow was fine.
I have attached some photos and a dimensioned drawing of
the tank. My tank design followed pretty much what Mike
Cuy did, except I did not add in the rear extension. If I h
ad to do it again I would put in the rear extension that Mike
has as it gives more support to the tank rear. It makes it a l
ittle more difficult to construct the tank, but I think it
=99s worth it. If you are following my tank dimensions, I w
ould make it slightly narrower. My tank is a little tight when
trying to run the fuel shut off, throttle and carb heat cable
s.
The tank support is two stainless steel straps running
fore and aft. These straps attach to the forward ash piece
at the firewall and the shelf behind the front cockpit ins
trument panel. This shelf is reinforced with =C2=BE=9Dx 4=9D
Douglas fir. There is a secondary support that goes left
and right under the tank, also made of Douglas fir. Fina
lly there is a top strap that goes across the top bow of the t
ank.
The attached photos should give you a good idea of what I
did. Also check Mike Cuys photos on the West Cost Piet
website, as that's where I shamelessly plagiarized my ideas
.

For those of you who are newer to the list, here's a page of a few of
the miscellaneous sketches that I've drawn to help others along while
building their
Pietenpol. Scroll down after you get to the page.
The fuel tank sketch/installation is in there along with a bunch of
other sketches---of possible interest.

Hi Dan,
Yes I did lean my seat back. I think it was 10 deg, whatever "Uncle"
Tony recommended. I have no problem with seat comfort. I am using
temporary temperfoam pads until I decided what thickness and density I
want.
Dan you are truly an Iron Man. I can't imagine flying for 15 hours. I
have done 10 hours at a stretch in the TriPacer coming back from out
west, but I had my Wife along with me to fly a little if I needed a break.
On my Piet I still need to add a little left rudder to keep flying
co-ordinated. I did not offset my rudder to counter act P-factor. I may
wind up doing that eventually. I do not want to add any trim tabs.

Oscar,
You are very right! Planning the routing of the throttle, carb heat,
fuel shut off cables before hand is important if you are making a front
bay nose tank. When I designed mine I thought I was allowing enough
clearance for the tank, but forgot to allow for the flanges on all the
tank seams. That made for a little tighter fit that I had planned on.

fuel tank. Like others have mentioned, it can get VERY tight getting cables from
the rear cockpit to the engine compartment past the fuel tank, especially
since you can't take a straight line going through the firewall... you have to
dodge around the fuselage upright just before punching out of the firewall going
forward. The small wires are no problem, it's things like the tach cable
(mechanical tach, anyway).

I just went back and checked my logs. It was only 12 hours of flying....but 15
hours overall that day to get home from OSH. Long but truly satisfying.
