Subject: | Landing Gear differences |
Hello to all on this forum. I am a new guy, still in the research stage but I am
looking with great interest in the Pietenpol. Part of it is the great look of
the open cockpit as well as the smiles on the faces I see in the Youtube videos.
But another big reason is the sense of camaraderie that I read in these posts.
I see people that genuinely enjoy seeing new people get excited about the
community. Very nice.
Here is my question. I am looking at the different landing gear setups, and I can't
choose between the wood gear with the long axle, and the Cub-style metal
gear (I know it pre-dates the Cub, but I just couldn't figure out a better way
to describe it). The paint scheme and design I want to use lends itself to either,
but I wonder about drag penalty. Yes, I know, if I am concerned about drag
on this airplane, I am probably looking in the wrong decade of design. But
I am talking about relative drag between the two styles-
1. Has anyone gone from one style to the other and can give me some idea of the
speed difference. A lot? Some? Not much difference at all?
2. Was one any easier than the other to build? I am not a welder, but have down
a fair amount of woodworking. I am more comfortable in wood, but could figure
out someone to help me with the welding and building of the metal gear.
I plan (in my mind, at least) to do a Corvair engine with as much HP as I can reasonably
muster (~100 HP). I figure if it worked for Mr. Pietenpol, it is good
enough for me. I am not really hear to discuss the merits of the engine, just
the questions about landing gear, so I will save the fight over FWF for another
day.
Thanks in advance for the information.

Terry, I would say the "Cub" style gear is less drag if you used 6 inch air
craft style wheels.- If you used open spoke wheels I think the drag would
increase.- I can't confirm any of this, the frontal area of the landing
gears are probably close.-I would say as far as speed is concerned it all
comes down to how the airplane is rigged, c/g, prop weight etc.- Just go
with which ever you like better.- As far as welding, there is a fair amo
unt of welding on any "all wood" design, not just in the landing gear, just
a requirement in joining steel togeather.- It is not that hard to learn,
find a EAA how to seminar and practice, it gets to be addicting and it is
fun when it "clicks and you get the feel of the torch.- Its is your choic
e so choose wisely.

Hello Terry
You are making a great choice with the Piet, as far as the gear type I think
the choice for many is more emotion driven. I think most go for the Jenny
style gear because it looks like a Jenny gear. There is no answer to the
question of which is better (like the corvair vs. continental debate). It
comes down to the look you want and as you mentioned whether you like wood
work or metal work more. The cub style gear is a significant amount of metal
work although there is also a fair amount with the Jenny gear.
I did the cub gear with 8x6 tires. If I was going to build another Piet
(which many have done) I would do a 'best of both worlds' design staying
with the cub gear but modified to use the big 21" spoke wheels as is used
with the Jenny style with covers as per Dom Emch:

Welcome to the list - I believe you have the list personality pegged

the various engine choices because we NEVER do that here. As to your
question about the landing gear I will leave that to more knowledgeable

Subject: | Gear differences |
Welcome to the LIST Terry and you're among good company with Ryan Mueller on the
list who is
also a Marine and very active in the Pietenpol community.
Personally I don't thing drag reduction on a Pietenpol is something a builder should
worry about
because the design, no matter how many little details you change still has drag
written all over it.
Shad Bell's words were golden---a lightly built Pietenpol (leave out the heated
seats, radio stacks (if possible)
instruments in both cockpits (what passenger really needs to see any instruments
anyway really ?), the heavy
upholstery and carpeting, the starter/generator/battery (unless needed for your
airspace requirements of course)
and rig the airplane straight and true according to the excellent guidelines in
EAA's Tony Bingelis set of builders
books. (set of four will cost you around $95 but they are worth every cent when
you have questions of any sort
during the building process.)
I say choose the landing gear that LOOKS best to you and built it. To me the
wood gear and wire wheels look
fantastic and there are no toe-in, toe-out or camber issues to worry about so my
airplane tracks straight and true
because of that. When you build the steel-tube landing gear you have to make
sure that your wheels are tracking
true and straight so your axels have to come out just so when going all that gear
welding. There are shims too
I believe you can use if you're using axel stubs to get your tracking true but
just something to think about.
For a wooden airplane there is way more metalworking and welding than I ever imagined.
I had to learn how to weld
and fabricate my own fitting which was very time consuming but little by little
you get better and better in making
parts and getting them to fit right.
You don't need a 100 horsepower engine on a Pietenpol. Many are flying today
(if the airframes are built LIGHT as they
should be) on Model A Fords and 65 hp Continentals with good two-person performance.
Ken Perkin's Pietenpol is Ford
powered and gives rides all weekend long at Brodhead and many to adult sized passengers.
I have a 65 hp Continental and have carried passengers close to 200 pounds but
you can't do that on an 85 F day.....keep
those heavier passengers for more dense air when the temperatures are in the high
60's and low 70's.
Lots depends on how much YOU weigh too as far as how heavy a passenger you can
carry. I weigh 195 lbs. and normally
my weight limit for a passenger (with about 10 gallons of avgas aboard--I hold
17 gals) is around 170 lbs. Normally
I require my passengers to be attractive females as well but that isn't always
mandatory--it's just a personal guidline
that I sometimes follow:)
Welcome to the list and stick with it ! Don't GIVE UP EVER ! The second best
thing you'll do in your life is to build
your own airplane....the best thing will be to COMPLETE it and FLY IT yourself
!

I do like the "Jenny-style" landing gear, so I expect that that is what I will
do. I have a paint/design scheme similar to a Jenny or to a a DeHavilland DH-4
in 1920's USMC colors. I think it would look good, but that is just me. The Marine
Corps flew a lot of Close Air Support missions in those biplanes down in
Nicaragua in the 1920's and really developed their tactics that would later serve
them well in WWII. I just would like to do something a little different along
those lines to reflect my Marine Corps heritage as well as honor those Marine
Aviators of the 1920's. So the Jenny-style works for me.
Thanks for the input.

Hi Terry - I'll 2nd Mike's welcome. I like your choice of engines. The debate
on this list is lots of fun regarding the pros and cons of powerplant choices.
Jack Phillips (engineer, pilot & Piet builder extraordinaire) LOVES the Corvair.
I can guarantee that he'll give you his unvarnished "support" on that engine
choice.
I'd suggest that you get the books Mike mentioned and go ahead and order the plans.
You can get started on wing ribs cheap & easy & continue your research on
the innumerable options you have building this airplane.
Mike - As a highly attractive, slightly-over-170-pound male, I'm surprised I have
not been offered a ride, yet.

Subject: | wire wheels and Jenny gear |
You can just about guarantee that when you take a plane with wire wheels an
d a Jenny type gear to any
fly-in or air show that you'll have more onlookers than and F-22 Raptor.
There will be rows of RV's, and other cool homebuilts but the wire wheels a
nd the Jenny gear are just
SO unique and beauuuutiful. Nothing against the Cub type metal gear on
a Piet--those are wonderful too
just that I prefer the look of the Jenny/wire wheel landing gear.
Here's a nice wire wheel Piet below that was built by Jack Phillips from Ra
leigh, NC.

Hi Terry,
Welcome to the list. There's a wealth of knowledge and experience here.
Use it to your advantage!
Are you planning on building the long or short fuselage? Wood or steel?
If wood, what species - sitka spruce, doug fir, poplar? How are you
going to cover it - Stewart System, Stits process, or something else?
What glue are you thinking about using - T-88 or West Systems epoxy?
Are you going to clamp your gussets to your ribs or use brad nails like
Bernard? Will you be building a single or 3 piece wing? Will you
construct your fuel tank out of galvanized sheet metal or aluminium?
Are you going to build your struts out of wood, steel or aluminium? Do
you have a supplier for your turnbuckles? Are you going to cut all your
wood yourself or order it from a supplier like Aircraft Spruce or Wicks?
Are you going to use modern instruments or sift through eBay and the
fly-mart at Oshkosh for antique ones? What prop are you planning on
using - wood, metal, composite? What diameter and pitch? Are you going
to use a tail wheel or a skid? Et cetera, ad infinitum, ad nauseum.
What I'm really driving at is this - don't get hung up on the final
product and what it will look like. Eat your elephant one bite at a
time. Buy the plans. Buy the Bingelis books. Buy some T-88 and some
capstrip and build a few ribs to see if you're into it. When you start
covering your plane (a many month process in and of itself), then start
thinking about the color scheme. Don't get down on yourself if you put
the project on the shelf for a while, but know this, if you touch it
everyday and work on it EVERY DAY you will end up with an incredibly
awesome time machine that travels at about 75mph no matter what gear you
decide on.
Good luck! We're rooting for you!
Cheers,
Dan

Dan,
Thanks for the response. Actually, thanks to ALL who have responded. You are right-
just do it.
I was a flight instructor in Navy Flight School in Pensacola many years ago, and
we would get a student who would want to drop because they were overwhelmed
by the idea that they could be flying jets off a carrier in as little as a year.
They were just overwhelmed by what was ahead of them. I would tell my students,
"Fly one flight at a time." Just put one foot in front of the other and eventually
you get there. The same applies in building this or any other plane.
One foot in front of the other.
By the way, I just mentioned the paint scheme/design because I find that by planning,
I create a picture in my mind of the end. My picture may change but it
gives me a starting vision. Besides, who wants to fly an ugly airplane, and I
have seen a few of those!
My plans are on order and I am getting ready to send off for materials to start
making some ribs. I will let you know when I get started.
--------
Semper Fi,
Terry

Subject: | Re: wire wheels and Jenny gear |
I have to agree on the wire wheel Piets...they look much nicer (and I
have a steel cub type gear). A friend of mine bought a wire wheel
Piet last year, I ferried it for him, man it was nice. My plane gets
attention at fly-ins and just about anywhere I land, but in a wire
wheel Piet I'm guessing people treat you about the same as the would
if you landed in an Apollo capsule. I get all kinds of funny
questions from non-pilots when I go to airport open houses, etc.
"Can it still fly"?
"How far can it fly?"
"What is it made from"? (while poking the fabric with a finger)
"How high can it go"?
Lots of fun. Some people can't believe I've flown it from TX to
Wisconsin and back. Seems normal to me.

It's looming large in my mind, Dan, as I wait for the installation kit for the

so everything will still fit, and then reinstall the reworked heads.
PLUS, Shelley made me buy her a house. We're closing in 2 weeks so that honey-do
list will be long. Not much spare time in the next 4 months! However, I have

Subject: | Landing Gear differences |
Jarhead,
Thanks for your service!
Not to be contrary, but I found the building of the Jenny style gear to be a
snap. All wood parts were cut to fit in less than half a day, on a table
saw, which is the only part that troubles most. Like you, I am strong in
woodology, and week in welding. Besides that, I have little to offer to
advise you on which way to go.
Happy building,
Gary Boothe

Subject: | Re: Landing Gear differences |
Gene,
Thanks for your thoughts. It does go back to my original question. What if any
speed difference is there between the two. In other words, how draggy are the
Jenny style? What kind of mods did you have to make. Beef up the attach points
of the fuselage?
Any idea how much (approximately) the Jenny style weighs over the Cub style?
Thanks again to all who have answered. My intention is to come to Brodhead this
summer. One good way to get motivated, I would think!

Subject: | Re: Landing Gear differences |
Terry - I'm not sure if anyone's changed their gear back and forth to check on
speed differences. It will truly not matter. It's a slow, draggy airplane no
matter what gear you use, as you mentioned in your original post. As someone
already said, you're going to cruise around 75-80 mph. (Someone will no doubt
pop up with "I cruise at 110." Uh huh.)
A lot of your questions are addressed in the archives. Folks don't mind answering,
but you can sure learn a lot using the search feature. I'm thinking the
weight difference is buried in there somewhere. You also learn a lot of other
stuff as you dig through.
I've read the veteran list members message to many new folks: get your plans, start
on something small (ribs - as you are), come to Brodhead (look forward to
seeing you there!), search the archives, read the Bingelis books, etc. It'll
all come.

You can be the first "Top Gun" Pietenpoler at Brodhead (and the first Piet
with an arresting hook). And you are correct, just one thing at a time,
- just get the plans
- just order some capstrip and plywood (and T-88)
- just build a rib jig
- just build a rib
- just build arresting hook
- etc

Hello Terry and welcome. About the landing gear...I can only comment on the
wood, straight axle type as that is what I have been working on the last f
ew months.- As someone else mentioned, I had my wood legs made pretty qui
ck as well. I did a lot of planning, drawing and thinking prior to making t
he cuts, but, for me, it was not nearly as bad as I thought it would be.-
It takes time, but it was really not bad at all to handle. Go slow and rea
lly pay attention to the details and it will come out fine.
-
My thoughts on drag...yes the Pietenpol is a drag queen. (Aerodynamically s
peaking...) But to me, that is a great reason to be very aware of it and tr
y to minimize it as best you can...same with weight.- I think you have th
e right idea about having some idea of how the finished product will look i
n your mind. That will help you decide along the way how to build/make ever
ything else look and it will keep you motivated. Having an overall image of
my finished plane has helped keep me interested and focused.
-
I really hope you stay with some type of military/Marine type look!- I am
doing that very thing...mine is Navy inspired.
-
Good luck- sir.

If I had to make a call on this one, I'd guess that the Jenny style gear would
have slightly LESS drag than the split Cub-style gear.
One of the least aerodynamic shapes is a round cross-section. The cub-style gear
is built entirely of round tube. The Jenny style gear has wood members that
are streamlined, so the main legs of the Jenny gear would induce less drag than
the main legs of the split gear. Now, the Jenny gear does have one big round
tube that runs from one wheel to the other (the axle), and cross brace cables,
while the split gear has the diagonal shock absorber bracing, so neither one
is very good in that area.
Probably if you were to add streamline fairings to the cub style gear, you'd get
the least drag.
In any case, neither one has any great advantage over the other, when it comes
to drag. It's really more a matter of personal preference than anything.

Rick,
I actually flew Hueys in the Fleet (I am a rotorhead), and flew T-34C's in the
Training Command. No tailhook for me, although I did live and fly off the ship
for 14 months.
I am "just" getting my plans next week.
Thanks for the motivational comments from everyone.

Subject: | Landing Gear differences |
I have to agree with you Chris. I always planned on doing the Jenny style straight
axle gear, but I was deading the construction. I followed your construstion
log and technique that you posted on you web site (westcoastpiet.com/) and it
was a snap. I didn't run into any problems. I was very happy how easy it was
to fabricate. I am like you, strong on wood construction but weak on welding.
Fortunately I have a friend who helped me alot with the welding.
I have finished up almost all of the airframe construction and will be moving the
airframe out to the hangar for final assembly and covering in a few weeks.
I am currently into the final assembly of my Corvair engine. My block and crank
are ready and my OT-10 cam will arrive from Clarks tomorrow.
I do plan on going to the next Corvair College to pick up some tips before I finish
my engine assembly. Fortunately the next college is close to home.

Jarhead,
Thanks for your service!
Not to be contrary, but I found the building of the Jenny style gear to be a snap.
All wood parts were cut to fit in less than half a day, on a table saw, which
is the only part that troubles most. Like you, I am strong in woodology, and
week in welding. Besides that, I have little to offer to advise you on which
way to go
Happy building,

To add to other's comments, the Jenny gear looks great, but it is a bitch to make.
Don't just start it based on written explanations or photos, go to someone
who has built one and work through it until you understand it completely. The
jenny gear DOES make a difference in the fuselage, so decide BEFORE you start
building the fuselage. It is also heavy and draggy. That is not to say that
it is too heavy, lots of Piets are flying with it. I understand that people
who use the Cub gear are forced to pull their wing aft to make up for the weight
difference. It is also very rugged and simple. It makes brakes more difficult
to add, but not impossible.
I don't think the Cub gear is much harder to make. It is lighter and more streamlined.
There are more wheel choices, and brakes are easy to add. The Cub gear
looks fine on a Piet, especially with wire wheels.
Just a few observations, I hope they help. I built my Jenny gear and am happy
to give any help I can. I had to make modificaitons to my fuselage because I
built it before looking too closely at the gear.

either, but I wonder about drag penalty. Yes, I know, if I am concerned about
drag on this airplane, I am probably looking in the wrong decade of design. But
I am talking about relative drag between the two styles-

I was a flight instructor in Navy Flight School in Pensacola many years ago,

Terry - I'm not sure if anyone's changed their gear back and forth to check
on speed differences. It will truly not matter. It's a slow, draggy
airplane no matter what gear you use, as you mentioned in your original
post. As someone already said, you're going to cruise around 75-80 mph.
(Someone will no doubt pop up with "I cruise at 110." Uh huh.)
A lot of your questions are addressed in the archives. Folks don't mind
answering, but you can sure learn a lot using the search feature. I'm
thinking the weight difference is buried in there somewhere. You also learn
a lot of other stuff as you dig through.
I've read the veteran list members message to many new folks: get your
plans, start on something small (ribs - as you are), come to Brodhead (look
forward to seeing you there!), search the archives, read the Bingelis books,
etc. It'll all come.

Oh, us aircraft engine pushers will wear him down one logical point at a

- with the 5th bearing and all of Wm. Wynne's mods - as it does to buy a
O-235, etc.

Huh? I built my 'core' for $3,000 (just a hair over). I'll add another
$1,000 for the 5th bearing. Can you get a new 0-235 for $4,000+? One
advantage to the Corvair is that a builder is capable of scrounging for
parts, and doing almost everything himself, that he is comfortable with.
Now, I'm no motorhead, and I'm certainly not a good scrounger, but I know of
those who are both and building for even less. I don't know how this rumor
got started that the engine is so expensive...maybe because WW has said he
will build and engine for $6,000 (probably more now). Yes, the mods can add
to that, but no one is required to use those mods. Stock oil coolers are
just fine for a Piet, and WW supplies shop drawings for those who want to
machine their own stuff.
Heck, you want to be a purist and do as BHP did? Your probably around
$1,200, but you won't get 100 hp.

You won't get a "new" corvair for $4,000. Maybe a rebuilt one, but

Nothing super duper or flashy, but I am planning to do all of the things that

He estimates around $5k of work, which includes some of the items I had planned
to purchase on my own (pistons, cam, etc.)... then I'll still need several
hundred worth of WW components to complete the task. But, I expect to have
a very robust engine that will offer me years of service at minimal expense when
maintenance is required. I mean, once all the heavy work is done, I'll be
visiting Napa and Summit for my service parts, right? Maybe I'll end up being
wrong, but from what I've read I expect that I'm on the right track with this
experimental power plant.
I've already got another suitable case and heads, and I've got leads on several
cores. I plan on riding the Corvair movement right into my next project, whatever
it may be.

Oh, I forgot to add... I don't give a rip what I spend on my engine. I'm doing
this for the fun and I chose the Corvair for a variety of reasons, not all of
which were based on cost. If I end up spending the same, or even a little more
as another engine, oh well, I'll still be flying.

1. Ash struts
2. 19" Aluminum rims
3. 3.50 X 19 motorcyle tires
4. 8 gauge stainless steel spokes
5. Axle
6. Spreader bars
7. All metal fittings
8. Bungee cords
9. All bracing cables assemblies
10. Brass grease cups
11. NO brakes
