You have a great looking little Piet as well.
Thanks for making the plans available to list members (I've downloaded a
copy for myself as well).
My little Piet has a geared speed 400 and Ni-Cads in it as well. Flights are
much shorter than 25 min but still great fun.
I do stick to tradition, low and slow most of the time, good stuff !
I think your is lighter than mine as well, mine was originally designed for
an .049, I modified it to suit electrics.
Anyway, keep on flyin!!

Hello Dick
Any trick to putting dihedral in a one-piece wing?

My speeds are about the same as Mike and Chuck.
Also I have a one piece wing with 1 1/2" dihedral at tips. It flys very
stable.

Walt,
I'm seeing speeds very similar to Mike C., with my A65 and homebuilt 72
X 42 prop. The next time I have to pull the prop, I'll probably rework it a
little bit to get more RPM, for a better take-off and climb. I'm still very
intrigued with the Scimitar Prop, and hope to build one some day, using Eric
Clutton's guide. Full power level flight, my adjusted tach reading is 2200
RPM. The A65 is rated at 2300 RPM. I have errors in my tach reading, as
well as my ASI, and have adjusted these errors to conclude the speeds. I've
done a few flight tests with the GPS, but neglected to put the results in my
log...oh well...guess I'll have to go do the tests again. Hey, theres a
good reason to go fly !!
As far as your increased speed with the dihedral, I'm betting you had
some washout rigged into your original configuration, and don't have washout
in the re-rigged dihedral wing. The penalty for washout, is drag. The
hershy bar planform of the Pietenpol wing does Not need washout, because it
naturally stalls inboard first. That said, I think I saw somewhere that BHP
did put a tiny little bit of washout in the wing, probably just to err on
the side of washout.

Gents,
I'm reviewing the GN-1 plans today. Some of the fittings are to be built fom .065
4130N. I've got a bunch of .063N here in the shop. I know that conventional
wisdom calls for up-sizing, but the next thickness from Aircraft Spruce is
.071. Anybody out there used .063 in their fittings?
Thanks,
Alan

Dick,
Thanks for the feedback. I started a discussion last year, but there were pro's
and con's for both dihedral and flat. boy, now I see first hand that dihedral
was invented for a reason.
Went up yesterday morning even though the winds were gusting. Even though I got
bounced around, it was still controllable.
flew south like a rocket, then turned North and kind of stopped. Guess the winds
were around 20mph up there.
It was fun.

I believe the plans call for .065 for the elevator horns. The new plans have been
revised to indicate .090 I think. .065 is ridiculously thin for elevator
horns, so if you plan on using the .063 for that I would not reccomend it.

| Subject: | New TACO T-shirt? |
I'm thinking about throwing away some more money on a new tee-shirt. You can
see the design, featuring some fabulous artwork by DJ Vegh by pasting the
below link in your browser.
This spec shirt would be printed on Haynes Beefy T 100% cotton material (a
tad better than the BYOP shirt) and the art appears on the front side. I might
have something printed on the back side, but this is just speculation at this
juncture.
The more shirts that are ordered, the "cheaper" the price. I got a quote for
20 shirts, mostly for guys like me that have be "supersized" in sizes X-Large
XX-Large.
If 20 people commit to buy one, the price looks to be about $21.00 each for
the shirt, and shipping to Knot-2-Shabby and then on to the final destination.
Adding art to the back of the shirt would add to the cost, and I'm not certain
if this would be an option since $21.00 is kinda pricey for a T-shirt.
http://customink.com/cink/r.jsp?E=sterling%40pgrb.com&F=tacoshirt
I'm open to other vendors who can do this for less mullah, if anyone can
provide a recommendation.
For those of you who haven't seen a hi-res picture of DJ's art, wow, it'll
knock your socks off. His design is simply stunning and it looks really nice on
a black T-shirt as seen in the link above.
Thanks,
Sterling

No real trick. I built a table, 30 ft long. As I recall it was only about 18"+/-
wide. I made sue it was level and ran a string line to verify a straight
edge and found center and raised the tips 1 1/2'. I scarfed the joint about 18"
and put 24"x1/8" ply plates over both sides of the splice.
After building the first spar I built the second on top of the first, to make sure
they came out the same.

Calm seas may not make a good sailor, but he usually isn't rebuilding
his boat either. Common sense and a gradual stretching of ones limits
in controlled conditions is the smart way to get the most out of ones
airplane, without coming to grief. There is another old saying.
Sometimes its better to be lucky than good.
