Subject: | Re: Plans Question |
I'm looking at page 8 of the 1932 F&G right now. The crossmember at both
the
front and rear landing gear/wing strut locations is 1" X 3/4" spruce.
Remember also that you're not just talking about the landing gear but
also the
wing struts. These crossmembers are a continuation of the strut system.
They
are compression loaded in negative G and tension loaded in positive G.
The
bottom plywood takes some of this load also.

"Perfection is achieved, not when there is nothing more to add, but when
there is nothing left to take away." Antoine de Saint-Exupery
get what figured out?? My first response to him was correct and still
stands. He asked about the dimensions of the ash piece when using the
wooden gear, and I correctly pointed out that per the plans, there is no
ash piece in the fuselage when building the wooden gear.

Subject: | Re: Lycoming 0290 for Piet ? |
This is from the 1988 Operator's Manual 60297-9
O-290-D = 260 lb
O-290-D2A, D2C = 264 lb
O-290-D2B = 265 lb
According to the F&G the "A" weighs 244 lb. Add
radiator, plumbing and water and you're likely looking
at 260 plus lb. So, you guys with A's, how much does
that stuff actually weigh?
I have both a "D" and a "D2". The difference is 6.5:1
compression ratio on the D and 7.5:1 on the D2.
D D2
TO hp 130 140
TO rpm 2800 2800
Rated hp 125 135
Rated rpm 2600 2600
With this kind of power you can balance the rpm/hp
to the performance you want, lower rpm, lower hp
thus lower fuel burn. The approximate rule of thumb
is 0.5 lb of fuel per hp per hour. 2000 rpm on a D2
gives 60 hp. 60 x 0.5 = 30lb/hr. 30lb= 5 gal/hr.
The D, at 2025 rpm, should burn 5 gal/hr. So running
a prop that will cruise at your desired speed at these
rpm will trade off to lesser takeoff and climb performance
than these engines are capable of. So the question is, is
this tradeoff acceptable to you in your circumstance?
Buy the damn engine!!! :-)
Clif
"Our doubts are traitors, and make us lose the good we oft
might win, by fearing to attempt."
....... William Shakespeare
I have found a local, 0 time since factory remanufacture Lycoming
0290 (125hp) cheap. It is complete. When I say cheap I am talking less
than a Covair project. This seems an excessive amount of horsepower for
a Piet. Best I can determine this model 0290 weighs 240lb dry. That is
not much different than a model =93A=94 from a weigh perspective. Does
anyone know of a successful Piet flying with a 0290? The owner is going
to list it Monday so I must act quickly.
All thoughts welcome.
Thanks,
Don

Subject: | Re: O-235 purchase |
Guys,
My C85 had a clean log book to day one. I put new Slick mags on, and
because I was not an A&P my inspector said the engine was not
"certified" and gave me 40 hours, but that's OK I'll go over 40 this
week. Also I'm on my own as far as the Repairman Certificate goes.

at which time the certified engine does not conform to the TCDS, and is
no longer a certified engine. My understanding is, the engine and/or
propeller has to conform to the TCDS to continue to be a certified
engine. The builder can get a repairman's Certificate after it is
completed, but he didn't have one when the engine was rebuilt.
Obviously, some FSDO people see this as OK. I suspect there are some who
don't see it as OK.

Good people,
I myself am enjoying my Piet, and really don't mind the 40 hour, Phase-1
fly-off period that is required for a non-certified prop and engine. It
was a long, but enjoyable journey (10 year building process) to get this
far.....I am loving every minute of it. 12 hours flown-off so far. I have
been able to work out a few bugs, such as my nose-heaviness, excessive ra
diator overflow on climb-out, oil leaks, brake adjustments, magneto slippa
ge etc. With every flight I am learning the machine and gaining the requir
ed confidence I will need in order to fly passengers safely. Yesterday I
went on a mini cross country, from Poplar Grove, Bigfoot in Walworth WI,
Dacy in Harvard IL, and back to Poplar Grove. Not very far but neverthele
ss a building block for me and my airplane. I am fortunate to have these
grass strips so conveniently located so close to home. I still haven't ha
d the cohones to try a hard- surface landing. Yesterday I also tried-out
my quick disconnect tail wheel-to-skid set up. Worked like a charm! I cha
nged it at the end of the runway with the engine idling.
At some point I will start loading up the front seat with sandbags.

Subject: | Re: Looking for a piet |
When I bought my Piet a couple of months ago there was also another one for sale
in Collinsville, OK. I didn't get any pictures of it or any details. I
believe it was Corvair powered and it could be a GN1. I really don't remember
the details but it might be worth a phone call for details and pictures.

Hey Gardiner,
Congratulations! What an accomplishment - the first cross country and
to such a good destination for it! Sorry I missed you (and everyone
else) at P-state. We had a broken exhaust stack and ended up pulling,
welding, filing, and fitting. How was the fly-in? Did you get a
chance to stay long? The morning's weather didn't look so good at

I personally would mind the 40 hrs either. Takes you that long to learn th
e aircraft. How's the "A" running? You mentioned it was stopping at idle
and thought it was just because it was tight. I'm still leanig heavily to
wards an "A". I would prefer a Warner Scarab Jr or a lambert=2C but they a
re way out of my price range for now.

Jeff, the fly in was great- a lot better than last time. A lot of planes,
antique cars and motorcycles.. The food was handled a lot better too. I left
Lagrange at 11 am and had one shower going over but the rest of the day was
perfect.with some high speed flyovers by a P51anf a T28. Cheers, Gardiner

That's great Lorin.
My wife has been asking for a ride in the Piet. The Mooney comment made me laugh.
The majority of my hours are in a Mooney and it pretty much the only GA

It's kind of a culture shock going backwards, so to speak. :D

One more question about spar placement. I know the 27 3/4" measurement on the rib
drawing is the important dimension. If I am going with 3/4" spars than should
I center the 3/4" spars in the 1" spar area so the new measurement distance
between the 2 qty 3/4" spars will now be 28" correct?
Did any of you place a piece of 3/4 x 4 3/4 spar material right on the jig to build
the ribs around or should I not do that.
Thanks again for all the help in getting me started.

I disagree. I think 29" on-center is a better dimension. It matches the 29" between
the attach points on the fuse. And even though WW thinks it's a misguided
belief that one can shift the wing back and forth to correct for CoG issues,
a perfect parallelogram *will* allow for such shifting. I do agree with his assessment
that the attach points for the diagonal cabanes should be heavy duty,
permanent jobs, if not welded, but that's a different issue.

Subject: | Re: Plans Question |
So, the f&g manual shows no ash. But as Gene pointed out, the original poster was
asking about the ash piece with the wood gear. Where did the poster see this
ash piece? Gene said the plans do not show an ash piece, but people have "added"
it. My plans show both ash pieces, clearly. I am trying to figure out what
plans,(not book or manual) show the fuselage with no ash pieces. It sounds like
there are plans out there different then mine.

All right, I went to the Matronics site and read this thread in the order t
he posts were made. I now see the what Gene is talking about, as well as th
e others and concur. As drawn wood gear, no ash. Improved plans show the as
h, but mods will need to be made to the original wood gear fittings to work
.- My apologies for the confusion.

Doug,
My engine is running like a top, but I can still detect the sputtering on
final at very low idle. I still can't figure out why. Like yesterday, no
sign of induction condensation, but it still happened. Runs fine as soon
as I coast out and on the ground.

Good people,

In order to keep the original print in good shape, my wife suggested that I use
carbon paper and trace the original print to the MDF. At first I thought that
would be difficult, but carbon paper is cheap (especially if you have an Office
Depot or Staples nearby) and the MDF is smooth so I gave it a try. It only
took about 30 minutes and I had an exact reproduction on my jig. This really
helped a lot when it came to placing blocks and cams for aligning the pieces.
Just figured I'd share that since it worked out good for me... I chose to glue
and nail my ribs. If you prefer to clamp, just look around as there are several
other cool variations around here.

Subject: | Re: Looking for a piet |
Since Dan brought it up, I'll provide what details I can on Roger White's airplane.
I have been hesitant on offering this info, but I spoke to him Friday night
and he said he wouldn't mind me posting some information here.
Roger completed "Precious Pete" in 1996. While it's not an exact Pietenpol reproduction,
it apparently flies real good according to those who have flown it
and it looks neat. If I remember correctly, he has a long steel tube fuse, metal
empennage, a single point wing attach (rather than the pair of cabanes shown
in the plans), steel gear and a Continental A-65 with metal prop for power.

That may be negotiable, not sure what he would take.

Subject: | Re: 40 hour fly-off |
Dan, I flew 38 hours before I got my nerve up to do a hard surface landing. It
did fine but I do like grass better. I haven't figured the rate of climb test.
All I know is that it takes off in about 350 ft and I can be at 500 ft. by the
end of a 5000 ft runway. After that my roc drops down and my math is not good
enough to go from there. Cheers, gardiner

Dan,
No I haven't. Mostly because my airspeed indicator is not working right. As soon
as I get that working at a reliable level, I can do some rate-of-climb tests.

Dan,

Then for a guy like me (who is 6'0 and 270 lb. mass of water, bones, and fa
t)-should-I then make my fuse longer to compensate for the heaviness of
my weight? It is reasonable for one to figure out the CG by adding the eng

-number to see if you have enough wing movement aft for compensation? Has
anyone figured out what modifications are needed to compensate for a heavi

Subject: | Re: CG for heavy pilots |
Hi Ken,
I think William's point is that you should not design your wing or it's
attach points with the ability to shift them fore or aft whenever you decide
you need to. I would think that a significant factor behind this belief is
the fact that he was burned in an Piet accident where the wing shifted
forward, fuel lines were ruptured, and bad things happened.
You can move the wing fore and aft, while you are building, to correct for a
known CG issue....but your ultimate construction of the diagonal strut
attachment, once you determine where the wing should be ought to be be
permanent (welded), or so beefy that it is just as strong.

Subject: | Re: Looking for a piet |
I think the engine is an 85 and has had a recent top overhaul. The wing
span is longer than standard but I don't know by how much. The fuel tank is
just behind the firewall and I believe about 18 gal. I have never flown
in it but the observed performance seems to be very good. Hope this helps a
little.

Since Dan brought it up, I'll provide what details I can on Roger White's
airplane. I have been hesitant on offering this info, but I spoke to him
Friday night and he said he wouldn't mind me posting some information here.
Roger completed "Precious Pete" in 1996. While it's not an exact
Pietenpol reproduction, it apparently flies real good according to those who have
flown it and it looks neat. If I remember correctly, he has a long steel
tube fuse, metal empennage, a single point wing attach (rather than the pair
of cabanes shown in the plans), steel gear and a Continental A-65 with
metal prop for power. I don't know much more on the specifics other than I
think he was asking $15,000. That may be negotiable, not sure what he would
take.
For those that don't know Roger White... he is a master homebuilder (EAA
#41) with several aircraft to his credit and a super nice guy. He has built
several types, such as the Wittman Tailwind, Cassut Racer and a Glassair
to name a few... he is currently working on a Corvair powered Bolkow Junior.
Jim Ballew is a good friend of Roger's that lives on the same field... he
also frequents the boards here. Perhaps he can offer more details or
clarification.

Good people,
I myself am enjoying my Piet, and really don't mind the 40 hour, Phase-1
fly-off period that is required for a non-certified prop and engine. It
was a long, but enjoyable journey (10 year building process) to get this
far.....I am loving every minute of it. 12 hours flown-off so far. I have
been able to work out a few bugs, such as my nose-heaviness, excessive ra
diator overflow on climb-out, oil leaks, brake adjustments, magneto slippa
ge etc. With every flight I am learning the machine and gaining the requir
ed confidence I will need in order to fly passengers safely. Yesterday I
went on a mini cross country, from Poplar Grove, Bigfoot in Walworth WI,
Dacy in Harvard IL, and back to Poplar Grove. Not very far but neverthele
ss a building block for me and my airplane. I am fortunate to have these
grass strips so conveniently located so close to home. I still haven't ha
d the cohones to try a hard- surface landing. Yesterday I also tried-out
my quick disconnect tail wheel-to-skid set up. Worked like a charm! I cha
nged it at the end of the runway with the engine idling.
At some point I will start loading up the front seat with sandbags.

In order to keep the original print in good shape, my wife suggested that
I use
arbon paper and trace the original print to the MDF. At first I thought
that
ould be difficult, but carbon paper is cheap (especially if you have an Of

took
bout 30 minutes and I had an exact reproduction on my jig. This really he
lped
lot when it came to placing blocks and cams for aligning the pieces.
Just figured I'd share that since it worked out good for me... I chose to

Yep. Sounds about right. If you want, split the difference and move each one apart
1/8" to get the 29" on-center measurement. N8031 is 29" OC and it flies just
fine.

That's one way to do it. The other way is to build the ribs to the plans
with a 1" wide piece in the spar position then add 1/8" ply spacers on
either side of the 3/4" spar when you install the ribs on the spars.

Or get a piece of plexiglass from Home Depot to lay over the rib drawing
(and that you nail your rib jig blocks to).

I wonder if it is from the windmilling of the prop?- Think of the rumblin
g and popping that come with down shifting a car to a lower gear at idle wh
ile slowing down.- Just another w.a.g.- Does it do it at idle with the
nose up (while flying)-. At a low idle, and nose down-the wind is-dri
ving the prop-faster than your static idle speed-,-possibly just raw
fuel that comes on through the exsaust,- with the throttle closed the air
is restricted, the engine being spun up a little faster as a result of the
relitive wind turning the prop, possibly sucks a little more fuel through
the carb venturi, and causes a temporary rich condition.

Just a few thoughts, not sure if they are valid or not.-

I personally would mind the 40 hrs either.- Takes you that long to learn
the aircraft.-- How's the "A" running?- You mentioned it was stopping
at idle and thought it was just because it was tight.- I'm still leanig
heavily towards an "A".- I would prefer a Warner Scarab Jr or a lambert,
but they are way out of my price range for now.

Good people,

I myself am enjoying my Piet, and really don't mind the 40 hour, Phase-1 fl
y-off period that is required for a non-certified prop and engine. It was a
long, but enjoyable journey (10 year building process) to get this far....
.I am loving every minute of it. 12 hours flown-off so far. I have been abl
e to work out a few bugs, such as my nose-heaviness, excessive radiator ove
rflow on climb-out, oil leaks, brake adjustments, magneto slippage etc. Wit
h every flight I am learning the machine and gaining the required confidenc
e I will need in order to fly passengers safely. Yesterday I went on a mini
cross country, from Poplar Grove, Bigfoot in Walworth WI, Dacy in Harvard
IL, and back to Poplar Grove. Not very far but nevertheless a building bloc
k for me and my airplane. I am fortunate to have these grass strips so conv
eniently located so close to home. I still haven't had the cohones to try a
hard- surface landing. Yesterday I also tried-out my quick
disconnect tail wheel-to-skid set up. Worked like a charm! I changed it at
the end of the runway with the engine idling.

I'm on vacation this week, so I'm going on memory here - the long fuse adds m

Subject: | Re: CG for heavy pilots |
Knowing that almost all Pietenpols are tail heavy (sometimes even after
moving the wing back several inches) and after reading an interview with
Bernard where he suggested moving the firewall forward 6 inches (when using
a non-Model -A engine) I decided to do the same. I figured why build an
engine mount with say 12" of extra length to get within CG when you can add
6" to the front of the fuselage and 6" to the mount and have the extra leg
room and fuel tank room? Yes I know it adds weight but an extended mount and
cowling adds weight too.
To answer your question the two primary means you have to compensate for
your weight is moving the wing back and moving the engine forward (assuming
you don't want to redesign the the whole thing). After completing my
airframe I borrowed some aircraft scales, assembled the airframe, added a
100 lbs of scrap iron behind the firewall at the fuel tank position, and got
the weights on both mains and the tailwheel with me sitting in it (setup
with top longerons horizontal ). From that data you can back calculate where
the engine needs to be to be within CG (15 to 20 inches aft of the leading
edge).
Preliminary W&B indicates that I shouldn't have to move my wing back
(Corvair engine, long fuselage plans, and I weight 200). But I have not yet
flown so all this is currently just idle speculation.

Subject: | Re: CG for heavy pilots |
The 1933 fuselage is 163" and the long fuse is 172 3/8". The long fuse moves
the firewall forward 2", the rear seat back 2", and all the rest is behind
the rear seat. If you are concerned about aft CG you are better off with the
short fuselage (even if you are going to use a Corvair or O-200).

Subject: | Re: CG for heavy pilots |
I have to double check the fuse length when I get home today, but the Piet I
'm rebuilding with a corvair, has the wing back 6", my grandpa built it like
that and he weighed in at 275 when he was flying it, said it made it just a
bit nose heavy, and the wing sits back far enough the rain misses the cock
pit :)

Must be nice to be able to climb in and set up shop behind the engine when
