Subject: | Wood Gear and "Deck Angle" |
--> Pietenpol-List message posted by: "Catdesigns" <catdesigns@comcast.net>
Seeing as we are talking about the wood landing gear, in the past it has
been said to use 12 to 13 degrees as the "deck angle", that is the slope of
the upper longerons when the plane is on all three wheels. Is this the
correct angle?
Mike Cuy, Jack Phillips, anyone with wood gear and a tail wheel, did you
make the gear taller so you could get the "deck angle" of 12 degrees when
you added a tailwheel. Based on a sketch I made tonight, I don't see how
you could have done it (added the height of a wheel) without making the main
gear taller to compensate. I get slightly less then 7 1/2 inches between
the bottom of the fuselage and ground (where the wheel would be). I'm
trying to use the plans A frame and coil spring design. Perhaps this is a
good reason to use the leaf spring design like Mike did. I guess this
question could be for anyone who added a tailwheel as it's more of a skid
vs. tailwheel problem.
So, do I need to add height to the gear when I add the tailwheel?

Just "renewed" today on a Cub. I remember when I first flew the Cub
(about 10 years ago) how strange it felt, and how hard to get the flare
right, and how hard to see. Now with 4 years in the Pietenpol, flying
the Cub is so much easier than the Piet.

Hiya Walt,
Congrats on the Cub. Ya just cant beat a nice flying Cub.
I walked out of the house this morning to 74F. at 11:30am it's still
only 78F. I just dont know how to act! Thats about 10-12 degs below what
it usually is by this time of day.
I suffered a heat stroke a year ago today up in Savannah, GA and spent 3
days in the hospital. It's true what they say, that after a heat stroke
your tolorance to heat is greatly diminished....or I'm getting older.
Probably a little of both.
I've been in Florida almost all of my 53 years but the last couple of
years the summer WX and humidity has really been working on me.
I'm ready for some cooler WX.
Have fun in the cub!
Dave....Down in Florida

Chris,
I have a fairly high deck angle of about 15 degrees. I have steel gear with spoke
wheels that are about 26" tall (19" rims). I really like the high angle.
The runway is totally blind in the flare but when I land 3-point it is all done
flying for sure. I've learned the trick to getting no-bounce landings is to
definately have the tail at the ground when the mains are even though it seems
to be a very high angle. I do know that Frank Pavliga lengthened his wood
gear somewhat to get a more 'correct angle'. This is because the "Flying and
Glider Manual" wood gear was designed for the shorter fuselage. When you go to
the longer fuselage the gear would need to be lengthened somewhat to maintain
the same 3-point attitude. Frank and I have nearly the same deck angle. Others
have less though, and seem to really like it too.

NX899DE has long fuselage (1966 model)
Wing is slanted 4" aft of plans.
A-65 engine mount is 1" longer than plans (just a little extra without losing 'the
look')
Axle is 1" forward of steel gear plans.
I have 14.5 gallons in the nose so depending how much fuel I have really changes
tail weight. Doesn't seem to be a problem though.
All of these were just compromises I came up with in talking to people who had
been there before. I'm really happy with these measurements although I think
they could differ some and I'd still like it. Just remember that one change leads
to many more so try to keep the changes small and few.

Aha! The "Dieselis" engine... comparable in weight and output to the old
Ford Model "A" and available in Europe. (http://membres.lycos.fr/dieselis/
). Keep us informed as to which powerplant you decide to adapt to the
Pietenpol. Will you call it an "AriaCampeggiatore" or "Campeggiatore
Dell'aria"? The front cockpit has plenty of room for a basket with bread,
wine, and cheese for a day in the field ;o)

Anybody have one of these? How does it sound? Too many bad pilots around
here, and I need a way to give them a piece of my mind.

Spoked wheel lacing advice:
The purpose of chamfering spoke holes is to provide proper seating and support
for the curved elbow of the spoke end. It would be a mistake to insert the spoke
into the chamfered side of the flange. That would result in a sharp-cornered
stress riser where you don't want it --- right at the elbow curve. Seating
the head in the chamfer is good cosmetics, but bad engineering. Good wheelwrights
know this and won't do it wrong unless you insist. Ask Buchannans to mail
you one spoke of the type you intend to use. Then machine your hubs accordingly.
Don't chamfer the flanges on both sides, as that weakens the spoke/flange
junction.
For all you guys who did it wrong --- not to panic. Of all the things that can
go wrong with an undercarriage, spoke failure at the elbow should be about priority
"Z" on your worry list.
I've been eying the temporary rim and tire from a retired Ford Escort, the engine
donor for my Ford/Scout inverted powerplant project. Cut the center out, leaving
a bare rim. Machine a one piece aluminum hub and lace it to the Escort
rim. Seal the nipples with some super goo, mount the tubeless temporary tire,
and add air. Presto --- a beautiful, poorboy set of lightweight, classic airwheels.
Sound too good to be true? Hmmmm.....
Happy landings,

Dan--- you can request various size (they use gauge sizes as I recall)
diameter spokes from Buchannan's and you have the
choice between steel, chromed steel, stainless, etc. I drilled my
holes for the spokes and then used a countersink bit to
accept the head of the spoke which has a taper and that helped seat the
spokes nicely in the hub.

Well, my first supervised solo was in a J-3 off of grass, at Tim's Airpark
north of Austin, TX in 1971 or thereabouts. It rented for $8/hr., wet,
solo. Since I had been told there would be no forward visibility after the
flare, I never thought about it and have always taken my cues from the side
peripherals. It feels very natural to me. It also felt very natural to
land the Cub in zero wind but in a crosswind, it was a bit squirrely. The
one thing that felt funny was having the stick so high up in my chest, but
maybe that was just me. The Cub taught me to slip, how to dance the pedal
dance, and how to land an airplane without power, which has been a very
valuable tool all of my aviation life. My instructors for my first 20 or so
hours never let me use power after we chopped it abeam the numbers on
downwind (except to clear the engine) and anytime my instructor was aboard
and we'd be turning base, I'd hear him ask me, "high or low? Fast or slow?"
which caused me to check my airspeed and position relative to the numbers so
I could adjust before it was too late.
I have yet to translate that experience to the Piet world but hope to do
that before Labor Day. Taxi testing of 41CC next weekend, if the Lord wills
it.
PS- I just viewed the first segment of "Building NX770CG", and it's good
stuff. An excellent addition to any Pietenpoler's collection. Hope to fly
with Experimental Seven Zero Charlie Golf one of these fine days, and to
call "SMOKE ON!" to good old Chuck.
