i totally agree with not adding more weight than necessary .... i've been throwing
all the wood pieces in the air.... the ones that don't come down i put on
the plane and the ones that do come down i cut up till they fly too..
43.13 says poplar is actually stronger in compression and in shear than spruce.....
seems that would be a good thing on the gear
thanks for all the replies...

Subject: | Chuck Gantzer's faring.... |
Don't know if this has been mentioned already but.....
Here are pics of Chuck Gantzer's faring on his landing gear. I thought he used
balsa but it looks like he used (at least on the landing gear) a hot wire and
foam that he cut to shape. Should have known, all of us previous RC builders
use something we learned from those fun experiences!
I once built a hollow core, carbon fiber wing for a high performance RC glider....hmmm,
maybe a hollow core Riblett for an Air Camper? NAHHH!!!
Anyway, just as a follow up...there's a bit of info on these pages:

It's always the weekend before Oshkosh, which would put it around July 22,
23, 24 in 2011. Keep an eye on the Calendar of Events at the 431 website and

Subject: | Re: Aircraft drag |
About a year and a half ago, one of the competition hang glider pilots did some
streamlining on his wing, by adding some fairings in areas where the tubing connected
to the wing, and in other places also. His first test of it was at a
competition where they were flying primarily ridge lift. One of the other pilots
flying an identical wing, except for the added aerodynamics said the guy
with the aerodynamics was able to stay several hundred feet above the rest of
the group, while flying noticeably faster than the rest of the group. He was probably
flying in the 80 to 90 kph (50 to 55 mph) speed range, and was probably
only 5 mph faster than the others. His work paid off, as 1st prize was $2K
or $3K on that meet. The difference in the aerodynamics on a Piet, might translate
to an extra 20 or 30 miles on a tank of fuel, which isn't a biggie, unless
you end up at a fly in, where there is no fuel available, or run into more
headwind than was forecast, or something of the like. After spending a little
more than 10 years as a truck driver, I found I liked having as much range as
possible, if I could handle the extra fuel weight, so I could buy fuel at better
prices, or more convenient or cleaner locations. I like the longer range
capabilities on a car, so I can stop every 100 to 150 miles to stretch, and 300
miles for fuel. Fuel not in the fuel tank, is like runway behind you - not
much use.

Sorry=2C Guys=2C I have been lurking but not participating or responding la
tely. My Dad had a stroke a couple of weeks ago and I have been spending a
lot of time tyraveling back and forth to Georgia. He is OK=2C and things
are calming down.
The recent photos are=2C like he said=2C from last January=2C so alot has
changed since then. I think Jack Phillips posted some photos of the comple
ted Piet this October after he came up and helped me finish off a lot of de
tails and start covering. It has now turned too cold to do anything in my
hangar. Before it did=2C I go the wing covered and about 2/3 of the ribs s
titched. (BTW=2C I did not glue to the undercamber=2C when shrunk=2C it onl
y has about 1/2" in the middle of the rib off of the bottom capstrip. The
stitches pulled it down nicely)
I plan to bring the tail surfaces and ailerons home and cover them over the
winter. Next spring I'll have to cover the fuselage and do all of the pai
nting. I also still have to build all of the cowling=2C which are cardboar
d patterns now. I really hope and plan to make Brodhead.
Hope everyone has a GREAT Christmas!!

A lot of the drag on the piet comes from the cables. A round 1/8in cable has more
drag than a 1.25 x 3in streamlined strut. I think drag reduction on a piet
is futile as long as you have all those cables.

All,
I found this video fascinating, too, as I've been thinking about whether and how
much to try to streamline various parts of the airplane. But Gary is probably
right. It probably doesn't pay to get carried away with drag reduction. From
one of my sources on aerodynamics, the formula for parasitic drag is as follows:
drag force = V2 coefficient of drag area
Since, for a given airframe (coefficient of drag and area) and air density (the
term), the only variable that varies is velocity (V). And that one varies alot
in its impact. Reducing the velocity from 210 to 70 (i.e. a reduction to
1/3 the prior speed), will reduce the drag by a ratio of 9 to 1.
So the key is to not try to fly your Pietenpol at 210 mph. Flying at 70 means
that you can reduce your efforts at drag reduction to a ninth of what you'd otherwise
have to spend time and money attempting.
Cheers, Ken

Charles,
You can build it any way you like...........but if you use those "V" struts, you
will be forbidden from calling it a Pietenpol. Also, keep in mind, if you show
up at Brodhead, you will be
banished to the far side of the airport, where the spam cans park.

I wonder if anyone has ever considered using a V-type construction on the
wing struts and doing away with the X-bracing of the wires. I am purchasing
a set of Taylorcraft wing struts from a friend of mine who had to replace
his because of some AD. He has punched the old struts and found that they
are fine. I don't see why with the proper attachment to the fuselage that V
struts wouldn't work on a Piet. Anyone who knows different, let me know.

Sorry to hear about your Dad's stroke, Gene, but glad to hear he'll be OK.
Have a Merry Christmas!

Sorry, Guys, I have been lurking but not participating or responding lately.
My Dad had a stroke a couple of weeks ago and I have been spending a lot of
time tyraveling back and forth to Georgia. He is OK, and things are calming
down.
The recent photos are, like he said, from last January, so alot has changed
since then. I think Jack Phillips posted some photos of the completed Piet
this October after he came up and helped me finish off a lot of details and
start covering. It has now turned too cold to do anything in my hangar.
Before it did, I go the wing covered and about 2/3 of the ribs stitched.
(BTW, I did not glue to the undercamber, when shrunk, it only has about 1/2"
in the middle of the rib off of the bottom capstrip. The stitches pulled it
down nicely)
I plan to bring the tail surfaces and ailerons home and cover them over the
winter. Next spring I'll have to cover the fuselage and do all of the
painting. I also still have to build all of the cowling, which are
cardboard patterns now. I really hope and plan to make Brodhead.
Hope everyone has a GREAT Christmas!!

Really nice work Gene. Please report your status on the covering. Love those
instruments. Are you on track for Brodhead?
