Steve, I just noticed a set of Aeronca system heat muffs on e-bay. Not sure
if your interested or not. So far at $10. with no bidders. Will end today
at 1400 PDT.
You indicated you had found a good looking heat muff for straight pipes. Do
you have an address?
Thanks
Gene

Gene,
Here is the heat muff I was looking at. I have no idea what the
quality is like, or how effective this one is. It looks nice, but the
only mode of heat transfer is from the header to air, there don't
appear to be and fins or anything to help heat transfer.
http://www.robbinswings.com/Carb_Heat_Muff.htm
Also, claims are made that ceramic coatings on headers help insulate
the header to keep heat in the exhaust and keep exhaust velocities up.
I'm skeptical that a significant insulating effect could be had by
this thin coating, but it is something to think about. Tests after
the heat muff is installed on a header with a ceramic coating
verifying that the RPM drop is adequate would make me comfortable with
it.
Let me know what you think.

I just noticed these custom heat muffs, intended for cabin heat. They
seem like they would have a much better heat transfer rate with the
inlet at one end and exit at the other. I bet this guy could make one
with only an exit at one end, and the other end could be drilled with
1/2" holes to provide the inlet. Since the air will spend more time
traveling along the header, I'm sure you would get more heat than with
the other "split tube" design. Maybe the builder could provide some
insight on expected RPM drops using these with lower HP engines.

Thanks Steve,
I'm going to contact them and get some idea of which one I should use.
Talked to my A & P friend yesterday and he says that he may have an extra
set of straight pipes. He's out of town for a few days but will look when
he gets back. If not, I will have a set made up as soon as I can (in the
next week or two).
Thanks again
Gene

OK guys,another question from the dumb ass. Very soon I plan to mate the wings
to the fuselage so I can cut the struts to fit and give it a weight check. Is
it possible to check the CG,and how close will it be after taking it apart again
to cover and paint? Gardiner Mason--- by the way, I have closed up the rear
door, and I think it is much stronger than before I cut it. The front door I'm
beefing up too when in the closed position.
Thanks

Good day Gentleman & Ladies
My build partner and I, are about to assemble the fuselage on our Air
Camper.
Are there any, significant weight and build differences in using an all
plywood fuselage stained, instead of cloth, paint etc.?
Could someone with prior build experience, please elaborate on the pros or
cons.
Is there some data available on the finished weight of a plywood fuselage?
Thank you

Marc,
Ken here in Fargo, ND and I am building a "wide body" fuse of all plywood. I
have both sides of plywood and the turtle deck of the same. When completed I plan
on using a very light cloth and West Coast systems covering! Charge on!

Subject: | Fall flying in the piet |
Hello group. Today I flew for about an hour and a half, and really just took in
the experiance. It was nice and warm, farmers out cutting off the beans, some
cutting hay for the last time of the year, and the leaves starting to change
color before they die and fall off at the end of another flying season. The
smells of fall harvest can eaisly be detected from 800 ft in an open cockpit.
You can also taste the dust coming off the bean fields as they run the combines
undernieth you gathering the years crop. It's funny how fast the fields
go from muddy dark brown with tiny green leaves poking out of the ground in streight
rows, to dry light brown dusty and dead looking fields. I got to see most
of this years cycle from the back seat of the Pietenpol. The only sad thing
of it all is that in a month or so it's all over for the winter, and cabin
fever sets in. On the other hand....It will force me to get back to building
my airplane, so I can experiance the thrill of
flying MY creation some time in the near future. To all you with flying Piets
take advantage of every warm, nice flying day, they are in short supply for the
year. To all those building, keep at it it! is all worth it in the end.

Shad,
I completely agree with you in taking advantage of the nice days. The last week
or so has been some of the nicest flying weather in a long time. All this week
is supposed to be nice too. Yesterday afternoon the whole family and I went
to the airport to hang out. I went up for a nice afternoon flight. We went
home and were there for an hour or so and my wife looked at me and said "you
want to go back and fly more don't you?" Within a few minutes I was headed down
the road and meeting my brother-in-law to drag him along with me. What an
evening for flying! There is definitely something about open cockpit fall flying
that is fantastic!
Hey, no complaining about winter and cabin fever! I flew every month last winter
except for February and that was only because I had the plane down for a little
maintenance. Someday I'll wise up though. Seems like the guys that have
been flying longer eventually lose the ambition for winter flying! Until then
I'm looking for some homebuilt ski plans. Anybody have ideas?

I've just stripped a lot of our fuselage fabric to repair some
damage. One advantage of covering the fuselage plywood with fabric
held off by fairings is that the fabric keeps oil, etc. off the wood.
I don't know if this makes a difference overall, but some of the
unprotected wood seems to have soaked up oil over the years and
appears a little weakened by it even though it was heavily varnished.
I don't know how general of a problem this is with uncovered wood
fuselage.
HTH,
Jeff

I built mine that way and compared notes with several others at the
time. Mine was about 2-3 lbs heavier. I covered my fuse with a 2 oz.
layer of fiberglass cloth and used West System Epoxy, then applied Spar
varnish over that. As I recall bare fuselage, fully finished was about
65 lbs.
I would consider going with the wood thikness as on plans and where you
are adding wood to the rear, use 1/16" plywood. Keep th weight donw in
the rear.
