My plan is to use weather stripping with the adheisive back for all gap seals.

I have found that the elevator and rudder response in the Pietnpol is super
b and requires no gap sealing unless you're thinking
you might get a slight reduction in drag but to me it isn't worth it. The
re is so much drag back there to begin (tail brace wires, tailwheel
and tail spring assemblies) with that getting a little less drag out of the
gaps will create more headaches than it is worth when they start
to peel and look ratty over the years.
Gap seals back there also make it more difficult to do satisfactory preflig
ht inspections of the tail hinges, pivoting hardware, and cotters/securing
nuts.
If you want drag reduction, build and RV-something.

| Subject: | gap seals on the tailfeathers |
I agree completely, Mike. For a few years I had gap seals (Duct Tape) on my
elevators. Saw no real impreovement in anything except I could raise the
tail a little earlier on takeoff. When the duct tape started peeling off, I
just removed it and have not put it back.
The ailerons are a different story. I built mine with piano hinges across
the full span of the ailerons, so mine are automatically gap-sealed. The
first time a I flew a Pietenpol with the barn-door type hinges and no gap
seals I thought something was wrong with it on takeoff. The ailerons were
less than half as effective as mine. Gap seals are VERY important on the
ailerons.

I'm not sure if the smoke oil (glorified mineral oil) I've sprayed has caus

work great as a laxative if you're constipated. No extra charge.

Gardiner;
I think many of the other smokers are burning baby oil, and I agree that the smoke
from it tends to be a little whiter and thinner. I did some research on the
Canopus oil that Mikee (and aerobatic performers) like to use. It's also used
as a form release agent for concrete forms, obviously is not harmful to the
environment since it washes off the form boards onto the ground, and is a food-grade
mineral oil. Shell has a comparable product.
Some people have mentioned using spent or dirty automatic transmission fluid (ATF),
and it will indeed make nice smoke, but it's not as innocuous as the mineral
oil because you're burning a hydrocarbon, but not burning it completely.
I wouldn't do it.
The Stearman chat site has a discussion about this subject and one guy said he
found a reasonable alternative... soybean cooking oil from Costco. $20 for 5
gallons. Food grade, good smoke, didn't make a mess on the airplane, but he said
that smelling it made him want to go eat at McDonald's. Worth pursuing.

Pietenfolk;
In preparation for the annual on my airplane, I updated the W&B sheet to reflect
the change to the tail weight with the slightly lighter Matco. In doing so,
I ran some what-ifs to examine both normal configurations and extreme loadings.
What I found with my airplane, and I'd like to see if anyone else with their
W&B on an Excel sheet wants to play with this, is that the passenger weight
does not shift the CG at all. I tried passenger weights from zero to 2000 lbs
(yes, one ton)- and the CG does not budge. I tried negative passenger weights
and the CG moves, but those aren't reasonable or rational numbers. The point
is, and it's been mentioned before, if a passenger can physically get into
the front cockpit and the gross weight isn't exceeded, the CG will not be affected.
If it was within range with pilot and fuel and everything else, it will
remain within range with any passenger you can stuff in the front cockpit as
long as gross isn't exceeded.
I would welcome anyone else's experiences with this phenomenon to see if it's a
general condition for most Air Campers or if it's specific to mine.

used as a form release agent for concrete forms, obviously is not harmful to
the environment since it washes off the form boards onto the ground, and is a
food-grade mineral oil. Shell has a comparable product.
