Don't know how far you will travel, but I am located in northeast Texas, about
25 miles north of Tyler. If you would like to see my Piet before it gets covered,
head on down. I am just beginning covering of the tail feathers, so come
check it out any time. In my experience, there's nothing like seeing a Piet's
construction before covering.

My airplane has a Scott tailwheel with leaf springs. I believe the one I have
is the Model 2000, 6" solid rubber, steerable. I really like the setup and it
tracks and steers perfectly. You can get an idea of what it looks like here:

I can take closer pictures of the setup if you're interested.

If you find Larry Williams, you'll have an excellent resource on the Pietenpol.
You'll also have located the one known as "The Top Curmudgeon"... he pulls no

If you have found Jim Markle, you will have found one of the very best people on

Funny Ken, I got hold of an instructor this weekend that has a Decathlon at
Meadow Lake and does tailwheel/aerobatic instruction. Hopefully an hour or
two of takeoffs and landing in the back seat of that and I will be ready
(or as ready as I am going to get).

Michael; are you talking about the cooling scoops/eyebrows? You can take a look
at this page to see what I've done, or am in progress of doing, on Scout:
http://www.flysquirrel.net/piets/engine/eyebrows.html
They attach to the engine in two places: at the top or inside, there is a mounting
flange that secures to two of the engine case bolts. At the outside, they
attach to two of the rocker cover screws. Total of four mounting points per
eyebrow. Let me know if you need any other info, but the pictures are informative
and as you can see, they are virtually identical to the scoops that are flying
on hundreds, if not thousands, of Cubs and their cousins. You can get an
idea of the problem areas on these parts by looking at pictures of old scoops,
like the ones here:
http://www.piperads.com/ads/j3-cub-cooling-scoops/
Anyplace you see stop-drilled cracks or doublers, that's a problem area. The scoops
get buffeted by propwash, leading to metal fatigue at the fastener connections.
If you figure 2300 RPM for 1000 engine hours, two propeller blades will
create an impulse 276 million times over that timespan. What's the fatigue
life of aluminum? Ten to the 7th cycles? ;o)

FOR SALE BY BUILDER with Ford B motor & mount, spare block, spruce fuselage,
& tail feathers. Contact for more info. Contact Carmen A. Natalie, Owner - located
Ravena, NY USA Telephone: 518-653-6066
Here are a few photos from when I first began the project. Parts have all sat
around for a long while. I'll get a few pics of the motor and other parts.
I have the model B engine and mount as well as tail feathers and rear lift struts.
Chad Willie made me an entire fitting set.
I believe I still have most of the instruments, but I can look to see what I still
have if you have an interest.
http://www.flickr.com/photos/canaweb/sets/72157635369569158/
Sitka was used throughout - obtained from a lumberyard in Stormville that used
to cater to the EAA crowd. A wood had proper # or rings /inch, etc..
Glue was aerolite..
one fuselage side was left off but I have it, ready to glue on. I'm sure by now
there are better glues available. Ply was marine, if memory serves..
First batch of photos is when I first started the project, last ones are current
state. Gear is split type and was once on a Pietenpol owned by Ernest Gann.
I found all instruments, and also believe I have some turnbuckles & shackles.
Empty block was used for spacing, but the B with all internals would need to
be rebuilt.

Wow, that looks like a nice project for someone east of the Mississippi to take

it of interest to me, if I were looking to build a classic styled Piet. Lots
of metal fittings there, too.

Ear muffs?
Never heard them called that before. Never thought of the engine as having ears.
I suppose eyebrows doesn't really make sense either, since the engine has the same
number of eyes as it does ears. But cooling eyebrows is usually the terminology
used (assuming you're referring to the scoops that are used to direct cooling
air over the cylinders, as per the J3 Cub and similar aircraft with exposed
cylinders). Referring to them as "ear muffs" will likely elicit a few raised
eyebrows (pun intended).
Just sayin'.

| Subject: | Re: Scott or Maule tail Wheel |
I thought you all (y'all) might be interested in what I found when I went to
make a repair on my tailpost. I had a tailwheel with a leaf spring that
stuck out the back about 14 inches. I managed to do a ground loop while
taxiing and the long tailwheel had enough leverage that it broke the
tailpost when the tailwheel hit the edge of the taxiway. It didn't help
that my tailpost had some rot in it.
When I removed the fabric to make a 10 in. scarf joint in the longerons,
much to my surprise there already were two scarf joints in the longerons!
(see photo). The old ones were made horizontal with Resourcinal and looked
good, so I made mine vertical (with West System).
I bought this Piet as a project and uncovered the wing and tailfeathers, but
didn't uncover the fuselage - should have. From some wear evidenced on some
fuselage parts, I suspected it might have flown sometime in its life. Now
I'm even more convinced of that, as it appears this is not the first
tailpost failure for this ship.
For those with this type of tailwheel, better keep it going straight (not a
bad idea, huh?)

Rick, I didn't quite do that but came close. I glued two more
longeron-size lengths of spruce on the inside, plus a gusset on the
bottom.

For those with this type of tailwheel, better keep it going straight

I agree with Rick, Larry. When I had a forced landing in my Piet, the
ensuing groundloop cracked the right lower longeron. I ended up going away
from the leaf spring tailwheel to the BHP A-Arm desgn, and glued a wedge of
spruce in between the lower longerons with plywood doublers top and bottom,
as shown in the pictures below:
Here I've glued the spruce wedge (with lightening holes) in place between
the lower longerons. Note that when I removed the plywood doubler along the
tailpost, none of the glue joints failed, but the wood tore. This was glued
with resorcinol.
Here is the finished repair, before covering.
The damage done by the twisting of the leaf spring in a groundloop convinced
me to go to the A-Arm design. I think that design would tear away before it
would cause such damage to the fuselage.

well I made another fun flight in my GN-1 this afternoon about 45 minutes before
dark. followed by the smoothest landing I have even made in it. (could be partly
due to a very weak bungee on the right side. by the time I turned at the
hangar and shut down the leg was splayed out pretty bad. I had thought I would
go to coil springs on them but as the time to fly just has not been that much
and I feel pretty comfortable with the Cub gear as it is. I just need to find
the lowest price but timely delivery source and get some in and change them.having
never done it I am not at all sure what I need.I seem to remember 1080?
as a strength rating but that may have been on my old Tri-pacer I used to have.any
good recommendations? I looked up Chief aircraft and have ordered from them
in the past but figured this would be a good place to ask first. thanks. Raymond

| Subject: | Re: Scott or Maule tail Wheel |
I am leaning more towards a the Scott 3200 Tail Wheel (Tube and Tire) as I have
a spare in the hangar from my Maule. I've only recently got back into flying
my Piet and I've noticed that the itty bitty Piet tail wheel really odd angle
with 600 size tires. I am thinking that adding the Scott 3200 tail wheel will
(1) give me better steering control in grass as well as on pavement, and (2)
will reduce this the angle of the fuse when on the ground. Looks like a few
folks have gone with the Scott 2000 tail wheel (solid rubber). It looks to be
a couple inches larger.
Has anyone gone to the larger tail wheel? Those of you in the know, do you know
of an adverse reason for using the larger tail wheel.
Thanks

What a brilliantly simple approach to adding an elevator trim tab. Do you other
DIY pictures of how you ran the cable and the elevator trim tab control mechanism?

| Subject: | Re: Scott or Maule tail Wheel |
Jim;
A couple of observations on the solid 6" Scott vs. the pneumatic 8" tailwheel.
First, weight. Most Piets tend to be tail-heavy, and according to the Aircraft
Spruce shipping weights, there is more than a 2 lb difference between the 2000
and the 3200. That's a lot. Second, aircraft angle in the 3-point attitude.
The Piet's FC10 airfoil can still be producing lift with 5.00 or 6.00 mains
and a big tailwheel. The original configuration is with a tailskid, which
put the tail down lower. The people who are flying with spoked wheels and a tailskid
probably have the plane nearer to a full-stall in the 3-point attitude
than airplanes like mine, and that gives you the slowest landing speed and the
shortest landing roll. Lastly, you should try taxiing a Piet with the 6" solid
Scott on grass or pavement. It will turn on a dime. Matter of fact, I have
thought of changing the spring tension on the tailwheel on mine to reduce the
sensitivity just a bit, although I do like to have the ability to make it go
precisely where I want it to go. Now I'll wait to hear from those who may be
using the larger tailwheel to see if I've missed an even better deal than I
have with the solid 6".

Wow. Peter's setup is absolutely gorgeous! Nice work, and professional. Mine,
by contrast, is stone-age crude. I have a bungee cord that applies biasing
force to the bellcrank on the walking beam. I made it adjustable, but have never
adjusted it because it never needed adjusting. Except it's been in place
for five years now and the bungee has all but lost its tension, so it's time to
replace the bungee. Here are some pix:
http://www.flysquirrel.net/piets/trim.html
Since Scout has a 16 gallon nose tank, I'll never be able to trim it just right
with the stone-age setup that I have. After I gas up, I need to hold a touch
of back stick for awhile. As the fuel burns off, it starts to go neutral. With
low fuel, I'm holding just a touch of forward stick. With Peter's setup,
I could just nudge the trim wheel and I could keep the altimeter needle perfectly
on my cruise altitude, but with my Fred Flintstone setup, I have to keep looking
at the altimeter and reminding myself to hold back pressure on the stick.
No... wait... was that forward pressure? I don't remember... let me look
at the fuel indicator (which is a bent wire sticking up out of the fuel filler
cap out on the nose!)
