Thanks for all the thoughts on this, and please keep them coming.
Our Piet had a huge trim tab, but for the opposite problem. The
former owner mainly flew solo and was a big, tall guy. He had
problems with nose up, not nose down. Obviously we could have left
the tab on and simply bent it the other way, but it was so huge and
ugly (and only on one elevator!) that we pulled it off. Even solo
we're getting nose down, so we still need a trim solution.

The recent interest in rib jigs, staples vs nails, etc.has prompted me to post
a picture of a rib jig I made while building an Airbike wing. I didnt use nails
or staples. Instead, I held everything in place with toggle clamps. What I like
about this method is that you can put the gussets on both sides at the same
time...Cuts glue-drying time in half. The price you pay is that the gussets
need to be cut very uniformly, which you can do by stacking the layers of ply
and using a metal template on the top of the stack. Carl Vought

Dear Brian,
I can at least speak for OSH. I took my oldest to Airventure in 2003 (he was 13
yrs old). We borrowed my buddy's pop-up camper and camped at Camp Schoeller.
No kidding: there were at least 20,000 other tents/pop-ups/5th wheels/drive-arounds/mobile
palaces at Camp Shoeller that week. At first, we felt alone-not
knowing anyone else out there. Like most campground camping experiences, as
the week progressed, we came to know the campers around us. After a big day
inhaling aircraft in the sun, we'd retreat to, what we came to call, home and
fire the grill for steaks and corn.
So camping at OSH is not a trout-filled dream. But it's a great place to hang
your hat and meet fellow aviation nuts like us.

Say Fred,
Have you looked at the new mountain bikes with front disc brake set-up They have
an internal spring that return the brake back to the open without any exposed
brake springs. The disc is bolted onto a spindle which could be taken off
and applied to our piets.....Just a thought but looks and seems very promising
and no need for a return spring on the toe pedal....
Any other thoughts.....

I am currently working on another project however I have an interest in building

and what tubing sizes did you use for the empennage? What other changes
have you made? Do you plan on creating a website show-casing your Piet and its

Jeff,
We had the same problem with NX18235 when it first flew. It required about 6
lbs. of aft stick pressure to maintain level flight.
One problem we found was the elevators were rigged slightly uneven. When
this was corrected the required aft stick pressure was reduced to about 2
lbs. The remaining trimming was taken care of by adjusting the stabilizer
turnbuckles.

Subject: | Re: Pitch trimming |
First, a few observations:
The Pietenpol Airfoil has a LOT of negative pitching moment, requiring
more down force on the tail than other types of airfoils, which is another one
of the things that cause this type airframe to be very draggy. Trim drag is
the amount of Down force applied to the tail, to maintain level flight at a
particular power setting. Another thing that aggravates the negative pitching
moment, is the actual weight of the flippers, which adds to the nose down
characteristic.
The pitch axis is dynamic on Pietenpols, similar to any other aircraft,
in that trim drag changes with changes in C of G. If you carried all of your
fuel in the wing (as designed), the C of G changes very little, hence, no need
for adjustable pitch trim.
Choices:
Adjusting the leading edge of the stabilizer down, to attain a nose up
attitude would be a ground adjustable trim method. If you use a cowling fuel tank,
an in flight adjustable trim tab, or some type of spring / bunji applied to
either the bell crank, or the stick, may be used. In my mind, I don't like
anything extra - if it ain't there, it can't break...kiss method.
I had similar characteristics as you (and many others), in that I had to
hold back stick, to maintain level flight when the C of G was at the forward
positions - full cowl tank. The thing I did was to experiment with a Fixed
trim tab on the inboard trailing edge of each flipper. This negates the weight
of the flippers, and has no moving parts. I used balsa wood trailing edge of
R. C. airplanes, available at hobby stores. Each one is about 5" long, and 1
1/2" wide, and blended right into the trailing edge of the flipper. I
experimented with the angle of the trim tab, and after many test flights, found
an
angle that would be hands off, with the C of G in the mid to forward range. To
make dynamic pitch trim changes, I simply adjust the power setting. I have
pictures of my trim tabs here : http://nx770cg.com/Fuselage.html

Rick,
The only problem I see with this is that the Elevator flippers are not
connected (no torque tube)
Thus you trim only one flipper and not the other.
Unless of course you place servos in both.
Same for aluminum trim tabs
Further the elevator cables are 3/32 with a strength of 1000+ Lbs.
With a 1 : 5 ratio on your stick you will need to put 200 Lbs of force on
the stick to break something.
The only way you will such high stress on the tail surfaces is during
aerobatics (better bring a parachute)

Rob,
I have not seen the Wynne video on engine disassembly so I can't comment.
But taking one apart is the easy part.
Putting it back together is the hard part.
If you are unfamiliar with engine rebuilding, get William Wynne's tapes.
I only have the introduction tape but that seemed very informative.
For rebuilding the Corvair you must get, WW Manual, Richard Finch's book on
Corvair and the GM Shop manual

You will get a rolling effect.
The cable and bellcrank system will transfer some trim to the other flipper
but not as efficient as a rigid torque tube.

Hi,
I have the disassembly video. Like the stage 1 assembly video it is good. He
talks you through deciding what to keep and what to discard and gives you a heads-up
on things that are problematic and what areas people tend to break when
they do it incorrectly. What I value most in all of his materials is that he
presents it in a way that reduces the process of disassembly and making the conversion
to a straight-forward process that any careful somewhat mechanically
inclined individual should be able to reproduce. For the $20 I spent for the
video I think it was worth it.
I'm not a mechanic but I am a careful, mechanically inclined individual.
That's my opinion.

Fred when choosing brakes bear in mind that with large diameter wheels
it takes a lot of brake to stop it (airplanes quit using large wheels
about the same time they started using brakes). Look at the size of the
front disc on a Harley-Davidson. Most go-kart brakes have pretty small
discs (because they have small wheels).
I have regular 6" Cleveland hydraulic disc brakes on my Pietenpol, with
21" wheels. The brakes will stop it (gently), and will hold it for a
run-up but cannot hold it at full throttle. My advice would be to use
the largest diameter discs you can find.

Jenny-style landing gear and will use disc brakes -- just wondering if
mechanical or juice...
Got all the tail feathers finished over the weekend -- less hinges (will
install those tonight). Came out nice and light...then I'll get the
fuselage down from the ceiling joists and start putting landing gear
together...

I hope you guys will forgive me if this has shown up on the list, but I
don't think it ever made it. I think it wound up in the spam heap.
Attached is a photo of A rib jig I made while buiding an Airbike wing.
It is mounted on a piece of particle board shelving and uses toggle
clamps instead of nails or staples. The advantage is that you can glue
gussets on both sides at one time. A little waxpaper helps keep the rib
from sticking to the jig.......Carl Vought

I have thought about using Mtn Bike disk brakes. The largest I have seen
are 203mm or about 8", but another factor is that the pads probably
don't have as much surface area Clevland pads or even small go-kart pads
- so the friction coefficient between the pad and brake will be less
I'll do a bit more research and try to figure it out.
Is there anyone that has used MTB disk brakes on a Piet? Hydraulic or
Mechanical? What size wheels? What size disk? Shimano, Avid,.....?
Kirk
>>> Jack.Phillips(at)cardinal.com 04/26/06 9:18 AM >>>
Fred when choosing brakes bear in mind that with large diameter wheels
it takes a lot of brake to stop it (airplanes quit using large wheels
about the same time they started using brakes). Look at the size of the
front disc on a Harley-Davidson. Most go-kart brakes have pretty small
discs (because they have small wheels).
I have regular 6" Cleveland hydraulic disc brakes on my Pietenpol, with
21" wheels. The brakes will stop it (gently), and will hold it for a
run-up but cannot hold it at full throttle. My advice would be to use
the largest diameter discs you can find.

Hi Fred,
I have 19" spoked wheels on mine. I use a 5" mechanical drum brake from Kart World
out of Cleveland, OH. The brakes are very simple and low profile. They
are cable actuated and are attached to hand levers under the instument panel.
The hand levers are just aftermarket motorcycle handles from a local motorcycle
shop. They are placed close enough together that I can hold both of them at
once for the run-up. They are just enough to barely hold the run-up. Sometimes,
by the time I finish the run-up I've crept a foot or so. I can deal with
that. The only other time I use them is for taxiing. They seem to be okay
for that. A liitle planning ahead is a good idea too.

The wheel covers are just regular doped fabric. I made an aluminum disk/ring at
the hub on both the inside and the outside. Glued the fabric to it then positioned
it over the hub. Then just glued the fabric around the inside edge of
the rim where the tire mounts. Made sure I had a few inches of glued area around
there. Then just finished it like any other doped fabric. Tire mounting
is not fun! Lots of soap, little wood wedges, cussing, and sore fingers. I
am not looking forward to replacing those things some day. I'll have to make
sure the kids aren't around when I do!

Rick,
If you are using this method, you need a trim tab on Both flippers. I would
caution against using metal tabs, because holes for the screws in the wood
will not only weaken the wood slightly, it is also a point for moisture

One of the guys in my Hillhoppers R. C. Flying Club (years ago) used separate

using the new type computer radio. The intent was to get a higher roll rate.
It
made no noticable difference. Conclusion was that the flippers do not have a

with his bride and sip julips like all elder southern gentlemen are suppose
to do. He has enjoyed the hobby for the last 6 yrs and especially the action
on this net. Building and flying your own airplane is more than a normal
college education. It would be hard to find an activity that required the personal
mechanical and technical skills and all other allied functions required to
complete an airplane. I would venture to guess that only about 5% who begin
ever complete and fly. Hope I'm wrong. I'll continue to monitor this series of
rare epistles but will try to refrain from clicking on the "write" icon. Just
remember one important thing:

Mine look exactly like Walts! If I remember correctly the hole dia. was about
5/8". I am Tool and Die Maker by trade so there are a lot of things on the plane
that were made or modified on the lathe. When I made those though I was laid
off and didn't have access to a lathe so I put the on my drill press at home
clamped them down really tight said a little prayer and open them up with the
right size hole saw. Finshed 'em off with some filing.

Subject: | Re: Trim tab was pitch trim saved Sean Tucker's life |
I use two ground-adjustable aluminum tabs on the elevators of my
Pietenpol. They are fastened to the underside of the trailing edge with
a couple of screws and zinc chromate putty (as used in aircraft floats)
is used to seal the screw holes against moisture entry.
These tabs are adjusted to trim for level cruising flight when the
forward fuselage fuel tank is 1/2 to 2/3 full. With a full tank, the
plane is nose-heavy and I trim by increasing power. As the fuel burns
off (and the a/c becomes lighter), I reduce power as required to trim
for level flight.
This works quite well, but I really would like to have a controllable
elevator trim tab as a backup in case of elevator control failure. Years
ago, I planned to incorporate one but never got around to doing so. I
have flown a Piet with such a system and it worked very well. The trim
tab was on one elevator only, and was added after the aircraft had been
flown for several years.

Chris,
My tailwheel design is fairly simple but a picture would help much better than
trying to explain. I'm headed to the airport in the morning so I'll get some
pictures and post them. It may not be the best idea out there but seems to be
working.

Glenn,
Are you talking about a hydraulic shop press? Something like this?
(attached photo)...
Not too sure how handy it would be for this project.
Unless you have access to a metal shop with shear, brake press, punch
press, notcher, etc (like some of us are fortunate enough to have), I
think the most useful metal working tools for building a Piet would be:
1. a metal cutting bandsaw
2. a drill press
3. a 4" angle grinder - with sanding discs and cut-off wheels
(attached photo)
4. a good big vise with some metal bending dies (see this link)
http://www.leevalley.com/wood/page.aspx?c=3D2&p=3D32011&cat=3D1,43456,434=
07
5. and the bench mount belt/disc sander mentioned by others
Most of the bending on the Piet is narrow strips (or very light gauge
stuff), so the vise-mounted dies should be adequate. So, unless you have
other, non-Piet uses for a shop press, I would spend my money in other
areas.

If you can find a metal working shop near your house that can shear up some
strips of .060 and .090" thick 4130
sheet for you ( shear WITH the grain lettering for safe/good bends) of
various plans-required widths, you'll save so much hassle
from having to band saw them up, not to mention saving the price on what
Aircraft Spruce or others charge for 4130 strip material.
If you look at the plans you really only need about 3 or 4 various wide
strips of 4130 sheet material to build the entire airplane.
It is WORTH looking around for a shop near you who has a shear capable of
cutting .060 and .090 sheet !

Glenn,
If you don't already have them, get Tony Bingelis' books (I thought I'd
say that before Mike Cuy did). I think the second one "Sportplane
Construction Techniques" is the one that shows step-by-step how to make
aircraft fittings.
All you need are a good vise, a good hammer (I used a 2-1/2 lb sledge)
and an "anvil" made from a piece of 1/4" steel with a variety of bend
radii ground onto its edges. It is helpful to have a metal cutting
bandsaw (I bought one from Grizzly for about $200 that worked great) and
I used the sanding disc on the side of my belt sander quite a bit, but
it is possible to do everything with handtools - hacksaw and a file.
Fittings seem to be a pain at first but by the time I finished building
the plane, the metal work and welding was my favorite part.

Another book that is useful is the EAA's Aircraft Welding book. There
is a one-page article in it written by (who else?) Tony Bingelis in
which he explains how to make the flared ends on tubing that are used in
a number of places on the Pietenpol, such as the spreader bar on solid
axle landing gear, and the pushrod that goes between the joysticks on
the torque tube. I used this technique on my jury struts as well as the
pushrods I used to connect my front rudder pedals to the rudder bar (so
I didn't have to use return springs), and the pushrod connecting the
front and rear throttles.

I hear that! I basically work on the project on weekends. To justify a solid
day of the weekend on the Piet, I feel an obligation to be a husband the other
day. (1 day a week!!!) Son is now in college so no hockey/lacrosse to cause
further time away from project. I have learned to tuck Piet time into free hour
blocks that are not consumed by other things. Early mornings (no power tools)
and late evenings are good quality Piet time. You will see shop lights on
well into the morning hours if I'm on a roll. Time mgmt is a bigger part of
this than I previously thought.

Fuel related problems are the most common reason that airplane engines
stop running. There are a LOT of factors to consider when designing a fuel
system. Some of which are:
1) The outlet should be the lowest point in the tank, in order that ALL
water will find it's way out when the plane is in the static laden position
(sitting tail on the ground).
2) There should be a removable finger screen in the outlet, to catch all th=
e
garbage that seems to find it's way into the tank.
3) The mounting system must be able to sustain at least 3 times the weight
of the total fuel capacity.
4) Quantity indicator must be reliable, and be able to monitor it in flight=
- Not Electric..too unreliable. A fuel cap with a cork & wire indicator is
simple and easy to make, and should also include a 90=BA Ram tube (1/4" tubi=
ng)
facing into the prop wash - to maintain a little bit of pressure in the fuel=
tank.
5) Fuel shut off valve on Certified planes must be behind the firewall, but=
I put mine on the front of the firewall before I realized that fact. My
reasoning is that there is No portion of my fuel system inside the cockpit a=
rea -
no leaks can find their way into the cockpit.
6) 3/8" fuel lines to maintain enough quantity flow.
7) Gascolator Must be in the lowest point in the fuel system (even lower
than the carb), to collect water. However, it Must be above the lower edge=20=
of
the firewall, in case you wipe out the landing gear, it will Not rupture the=
fuel lines.
For my cowling tank, the bottom is sloped forward, so when the plane is
in the static laden position (tail on the ground) any drops of water will dr=
ain
out of the tank, into the gascolator. No fuel lines or fittings are in the
front cockpit. I installed a fitting on the top, at about 10 O'Clock positi=
on
(viewed from the cockpit), to fill it from the wing. My quantity indicator=20=
is
a cork & wire, similar to a J3.
I made my fiberglass cowl tank with the flanges on the sides of the tank=
,
to rest on the top of the longerons. I put a lot of time and thought into
the mold for the tank. I made the inlet on the top left side, (at about 10
O'clock pilot's view), and made a fiberglass blister stand outboard of the
cowling, to prevent possibility of leaks entering the cowling. The outlet i=
s also
outside of the cowling shelf, and points forward. There is an EL fitting, t=
hen
the 3/8" ball valve that is cable operated. The bottom of the tank slopes
forward, while in the tail down attitude (as it sits in the hanger), so any=20=
water
in the tank makes it's way all the way out of the tank, and into the
gascolator (a very important design criteria). I used the aluminum 'weldabl=
e
fittings' that AS&S sells, glassed in, at the inlet and outlet. On the outl=
et side, I
modified a finger screen, so it threads into the 'weldable fitting', by
taping the o.d. threads, and then the 90=BA EL threads into the 'weldable f=
itting'
on top of the finger screen. As a result, I was able to squeeze a lot of fu=
el
in the cowling tank. It holds 10.7 gals. I didn't know how much fuel it
would hold, till I did a leak test, by setting it up at the gas pump, at the=
angle
the tank sits in the plane, and put one gallon in at a time, then dipping a
stick into the fuel, to mark off each additional gallon. That's how I made=20=
my
'Fuel Quantity Indicator'. I topped it all the way off, then put the full

I have seen the "inside triangle block technique" at Broadhead (see

and some people in the archives have mentioned that they had problems after
a number of years with rectangular 1/2" wide 1/16" ply strips attached top

Jim,
I did mine exactly the way you did it. (only used different tools) with
good results
Rick,
Seems to me the triangle blocks amount to lots of weight. If I decided
on the blocks, I would only make them about 3/8 to1/2" long on the right
angle sides at most.
Still best to build to the plans,,,I think.

Well, I don't know about "best" way but here's a nice simple way:
Cut grooves in the TE of the rib (I used a biscuit jointer) and leave
a tongue in the "front" part of the TE that will go into that grooves.
You could even use a biscuit jointer on both and insert a biscuit.
I left a tongue on the "front" of the TE material and used a laminate
trimmer bit to remove the extra after I epoxied the TE material into the
groove at the back end of the ribs...
Not sure how clear this is but if the attached picture leaves you with
more questions or wanting more clarity, send me a note offline.

I used 1/16" Plywood Plates, 1/2" wide X about 2" long, the way it shows in
the plans, then feathered each end down so it didn't leave a bump. With the
fabric on, you have to look pretty close to see the plywood strips. After
pre-fitting everything, I used rubber bunji chords to hold the trailing edge in
place while the adhesive cured at the butt end of the ribs, and the plywood
strips. I used T88 epoxy throughout the airframe. No problems anywhere with the
adhesive, after almost 280 hrs flight time.

I was wondering what would be wrong ,if anything ,about putting the

would be outside the aircraft and probably not look as good but geeze it
would make life a lot simpler and you could inspect it a lot easier as
well.Now all my connections for the elevator are inside and behind the
seat and chances of a lock wire breaking and me seeing it are reduced
considerably.As far as drag is concerned,I hardly think it would make
that much difference.

Use a horseshoe-shaped piece of 1/4" plywood glued to the spar face and
position the end of the 1/2" x 1/2" brace in the 1/2" x 1/2" opening of
the "horseshoe".
This setup captures the brace and the relatively-large glued surface
against the spar face provides lots of shear strength. It has worked
fine on my Pietenpol for nearly 36 years.
A simple butt joint will not work, against the spar face or against the
inside of the tip bow, where extra glued area will be needed to hold the
brace in position against fabric tension.

Rick H.,
I didn't use the "horseshoe" plates on the 3/4"x 3/4" compression struts
on my Pietenpol, but they could be employed there to help hold the
struts in position. I used the triangular (sort of) gussets as shown in
the plans and they seem to be satisfactory for this purpose.
If you wish, I can send you (off list) a photo showing my Pietenpol
under construction with a view of the compression struts, etc. It is a
black and white photo and was taken, in 1969, by a friend who was the
co-builder of a Pietenpol in 1931 (when he was only 16 and the other guy
was just 17!).

Subject: | Tailskid Tailwheel |
From: | "Don Emch" <EmchAir(at)aol.com> |
Hi Guys...
This is my tailwheel that Chris was asking about. I thought I'd post a picture.
It is basically just a wheel added to the plans skid. The wheel is a 4" unit
from Wick's. The fork is welded up and has a vertical steel tube bushing into
which an AN8 bolt is pressed (1/2" bolt). This is the vertical shaft of the
fork. A welded up 'T' tops it off which is connected to the rudder cables.
An AN3 bolt goes through the AN8 bolt in the fork and in the 'T' to lock everything
together. The shaft of the fork fits into a bushed tube that is weled
to the A-frame. Plates are welded top and bottom of that. The spring is from
a fork tube from the front of a wrecked motorcycle. $2.00 from the local junkyard.
It started out about 2' long and had to be cut down. The cables connect
to the rudder cables under the seat with #10 electrical wire connectors.
The tubes tend to want to twist when turning left or right so I plan to help that
by welding a cross piece near where the tubes meet the fuselage. It probably
isn't the best idea out there, but seems to be working for now and is fairly
light in weight.

Actually if I had built this plane from scratch I would have put the

I have two turnbuckles on the rudder horn, and four turnbuckles at the
Flipper horns. Like you said, easy to get to, adjust, and inspect. Eventually,
I'm
going to change out the rudder cables, and instead of turnbuckles, I'm going
to use two straps made from .060" 4130, which will be about 7/16" X 1
1/2"...similar to motorcycle master links. I have a local shop that will shear
4130
for me. I can make a dozen of these things for the price of a single
turnbuckle, and vary the length between the holes of each pair by a few thousandths
of
an inch, then find the ones that take the slack out of the cables. List the
length on the part, and keep the rest for future adjustment requirements. I'll
use #10 AN bolts, with locking castle nuts. I'll place them at the rudder
bar, instead of back at the horn, to save a little weight on the tail. I
haven't used this method yet, but I don't see any reason why they couldn't replace
all the turnbuckles in the control system, because None of the control surface
cables on the Pietenpol should be tight...just take the slack out, and that's
it. Before doing this, It would be interesting to compare the tensile
strength of these straps, with that of a turnbuckle.

Hi Guys...
This is my tailwheel that Chris was asking about. I thought I'd post a
picture. It is basically just a wheel added to the plans skid. The wheel is a
4"
unit from Wick's. The fork is welded up and has a vertical steel tube bushing
into which an AN8 bolt is pressed (1/2" bolt). This is the vertical shaft of
the fork. A welded up 'T' tops it off which is connected to the rudder
cables. An AN3 bolt goes through the AN8 bolt in the fork and in the 'T' to lock
everything together. The shaft of the fork fits into a bushed tube that is
weled to the A-frame. Plates are welded top and bottom of that. The spring is
from a fork tube from the front of a wrecked motorcycle. $2.00 from the local
junkyard. It started out about 2' long and had to be cut down. The cables
connect to the rudder cables under the seat with #10 electrical wire connectors.
The tubes tend to want to twist when turning left or right so I plan to help
that by welding a cross piece near where the tubes me!
et the fuselage. It probably isn't the best idea out there, but seems to be
working for now and is fairly light in weight.
Don Emch
I also added a tailwheel to the plans type tailskid, after about 35 hours of
operation. When making changes, Nothing is free, everything is a tradeoff.
In this area, the tradeoff is the deck angle (static laden) of the three point
attitude. With the skid, the tail was lower, and I was able to do full stall
landings much easier than now. With the wheel back there, the tail is higher,
and at 3 point touchdown attitude she hasn't yet reached the 'Critical Angle
of Attack', and the wing is not yet done flying, and a bounce sometimes
occurs. This is the reason I located the tail wheel Behind the skid plate, as
opposed to under it - to get the tail as low as possible. On the grass, 3 out
of 4
landings are greasers when I touch tail first, but Every time I have tried
full stall on the hard surface, she bounces, even when I touch tail first. For
this reason, I have to wheel it on the hard surface, and put up with the long
roll out. I much prefer full stall landings. Those few seconds during
touchdown are the juiciest part of the flight for me !!

My deck angle is already a little high, I think around 15 or 16 degrees, but not
sure I'd have to measure again. The plans split axle gear is taller than the
wood straight axle gear. The wood gear usually is used with the spoke wheels.
I decided to used the spoke wheels on the split axle gear. So... this makes
it kinda tall. I've seen Piets go from one extreme to the other in the deck
angle. I seem to get close to full stall 3-points. Just another area where
little changes lead to unique airplanes!

That's just what Don E., and others, did with the wire wheels. I have the
8.00 - 6 tires, making it a lower deck angle of about 11 degrees. I don't
really see it as a problem, just more of a challenge to get a full stall landing

and on the plus side, I can step right in, without damaging the family

Hi Guys...
I figured out something really cool the other morning while flying. Others I'm
sure have figured this out too. I don't have any kind of pitch trim. I have
a nose tank that holds about 14.5 gallons. While somewhere around 8 gallons
it is pretty much in trim in pitch with my weight. If I let go of the stick and
leaned back it slowly pitches up. If I leaned forward it slowly pitches down.
I know it only makes sense but I don't think I've ever flown anything that
is so easily affected by weight movement!

Or make the same thing out of wood as a part of the trailing edge

Don-- I'd have to concur with Jack Phillips in that pavement landings are
somewhat more challenging in the
fact that you get faster response directionally. Nothing dramatic, but it
makes you concentrate more on being
in good alignment on touchdown. To me, using the right tire pressure for
pavement can make a difference in wether
I rebound into the air or if she 'sticks' but then again that factor is
based on how hard you hit as well:)
I had no real concerns as the straight axle gear leaves no room for wheel
castor and camber errors as does the kind of
gear you built. If your gear is true, and more importantly each wheel
tracking true to the other, you should find pavement
pretty much a non event.

I'd like to add one item to Mike's post. I try to avoid the seams in the
runway if possible. I've landed on a couple where the joint in concrete has
caught on the tailwheel. Also I have found carrying 1100 rpm all the way
down makes a bounce less likely or a sudden flop onto the runway in the full
stall landing.

Clif,
The first thing you would have to do is figure out the amount of urine stored
inside the bladder. Then applying some mathematical calculations, you can determine
the weight of the uric acid versus untainted liquid water to arrive at
a weight per ounce. Then subtract that number from 6.6033 to determine the correct
amount of ballast within the bladder. In the sagittal plane you need to calculate
the arm for weight and balance to find a starting point of adjusted movement
of weight relative to center of gravity in the aircraft and the human
body. Then and only then can you get the true accurate number of forward weight
deflection within the cabin of a pilot who has to pee......

Hi Ken
Perhaps you hit on something. Yachts are using active trim tanks usually
side to side to reduce heel. Perhaps you could install a small soda bottle
fore and aft with a a manual trim pump in the cockpit. Putting the tank as
far aft as possible would give you a good amount of moment. You could even
have a third port in the cockpit so you could have a little drink while
flying along. It could be a problem in the winter with freeze up but I'm
sure some suitable ducting could be worked out.
Could call it the wet trim system. Thinking more about it the weight
penalty is not good perhaps Helium ballons stuffed in each end with a
transfer.............................

Don,
I used to mess with the trim on a Cessna. Trim it perfectly, then lean
forard and put your hands over the inst. panel. Down you go. same with
leaning back in the seat with hands over head. Up you go.
Here's something that I've tried, and not too many had heard of it.....Trim
out a plane at a certain alt. Say 1000 ft. Now don't touch the trim, but
pull up and climb to 2000 ft. Let go of the stick/wheel, and it will
slightly nose down and slowly lose altitude. The rate of decent will slowly
diminish, and it will settle back exactly at 1000 ft. So the trim will be
different on any day for any density altitude.
Neat trick.
Also flew my old Fisher 404 from a nearby airport back to my home airport
(about 15 mi) hands off, just sticking my fingertips out each side of the
windshield, as needed, to turn and correct heading. Try it,, it's fun

Don,
Yeah, it seems that when you land on grass, it's both the grass and you
that interact for the landing. But on pavement, it's all yours.
Just go to the airport on some evening where there are no spectators.
Spectators ruin the concintration
I've found that when landing the Pietenpol, to give a little power (about
1000 rpm) at or before the time of the flare, so you don't get the drop.
I had to get over the fear of the end of the runway comming up. Thought
about it all the time, and that ruled the landing. but when I was aware of
it,,,every time I landed, I'd see what runway was left. There was always
plenty. So then I was forcing myself to not worry about the runway left, and
about the quality of the landing. Now at the flare, time slows down, and
with some power on, I feel, feel, feel, for the grass. they are alot better
this year.
I like the comment that the only difference between a grass landing and
pavement landing,,,,,is that on pavement, you have to spit out your gum
first.
Talked to the owner of a parachute jump school about this. I'm 58 so he
seemed to be a kid. But he owns a Cessna Caravan, Super Otter, and a
Cessna 182.
His advice was that you need 100 hours in a plane to be comfortable in it.

To all Corvair flyers:
This afternoon I visited an open house at a local FBO and float storage
business at Lake Hood here in Anchorage. I went specifically to find an
A&P
that had been identified as an EAA technical advisor who works there.
After asking him if he would be available to help me with my project he
said
"sometimes," and asked what kind of project I was working on? When I
told
him about the Pietenpol project, and that it came with a turbo-charged
Corvair engine, he immediately said, "I am not a fan of automotive
engines
in aircraft, those Pientenpol builders seem to like them, but then again
they are flying over farms and fields, and up here we don't have any of
those, so if your engine quits..My advice to you is to get a 0-200 or an
85
horse engine for $15-16,000 and forget about the Corvair.
My question is how many of you using Corvair engines have encountered
mechanical or carb ice problems while flying with this type of engine,
and
been forced to land as a result of either?
Don't worry, I am not easily intimidated, and will forge on despite this
type of blatant opinion.

Got the same type of response from the ABDAR and various folks in my EAA chapter.
He didn't say he wouldn't do the maiden or assist in his capacity as Tech
Counselor but I also got a lot of "encouragement" to abandon the Corvair idea.
In fact I was encouraged to abandon the idea of building a Pietenpol which is
said is a "dangerous" plane. I think he is just looking out for me since the
Piet seems to require a little more skill than the average plane, and although
I'm building the plane, I am not a pilot. I'll be interested in seeing the
responses.

Here is another way of responding to your "Alaskan logic";
the difference between a Corvair engine a Continental or Lycoming is that those
"airplane" motors are wired together! Same cast metal, same iron, same steel
or aluminum, same bolts, except the "airplane" ones have holes in them!
Somewhere I heard, (it may have been some drunks around a campfire), "GM put more
man hours into engineering desgin of the Corvair motor for use in aircraft
engine than did Lycoming and Continental combined put into the design of their
engine"! Otherwise. there is no diffence, other than when those damn lawyers
get envolved.

Rob,
I fly a Corvair since late August of last year, I am still working away on
the 40 Hour test period, weather and work have been getting in the way.
A few hours in to the test phase I had a engine out and had to make a off
field landing, which was no problem as I had enough altitude to find a good
field.
No damage to the Airplane and a few experiences wiser.
The engine out was caused by a fuel starvation problem.
I used a 11 gallon wing tank and a 2 gallon header tank, the 2 gallon tank
was empty when I landed. ( could hear the fuel flowing back in when I was
on the ground)
The original system had a ventilation line on the 2 gallon header tank to
avoid air in this tank.
However in flight this vent would create a pressure on the header tank that
stop all fuel from the main tank.
The vent cap of the main tank is also in a low pressure area on the wing,
which contributed to the problem.
I made some fix with a check valve on the header tank vent line ( air
allowed out but not in) and re-arranged the vent line to avoid excess
pressure.
I flew another 4-5 hours this way but was never comfortable with it.
A 2 gallon header tank gives you about 25 minutes of airtime at which time
you get the urge to land.
I finally removed the 2 gallon header tank and replaced it with Piper J3
tank in the nose (12.5 Gallons) it shifted my CG forward which I
compensated with changing my exhaust system ( changed the cast iron
manifolds for a much lighter header system)
Been flying with that setup for more than 20 hours now and have had no
problems.
My Corvair is a '65 , 110HP Corvair conversion as per William Wynne manual.
It is a very smooth and powerful engine, I would rate its reliability as
very high, very close to a Continental.
If it had dual spark plugs it would be an equal.
Still fly with a non nitrated Crankshaft too, although I have a spare one
that is being nitrated.
If I had a O-200, C90/85 I would have used it,only because you do not have
to deal with a 40 Test phase (25 hours if you have a aircraft engine)
Of course there is money issue as well, total expense on my Corvair was
6,000- US with all moving parts to new specs, I did not cut any corners on
rebuilding the engine. (the crank in hindsight being the exception)
Furthermore I believe two more Pietenpols had to make a forced landing last
year, both Continental powered, go figure..
It is very rarely the engine that causes a problem it is most likely the
systems around it that fail.

Good reply.
Yes, I have read Wynne's website info and the story by an obvious
follower
of his, also a journalist.
My thinking is, if carb ice is a problem with this engine, then what has
been done to thwart it. Wynne makes reference to a joint carb heat
device
that as you throttle back applies carb heat. I talked with a guy who up
here
who ran the Corvair in VW buses, and he said they are "very" prone to
icing
up and also uses them in air boats and more than once has seen ice build
up
on them, and even wrapped the manifold with asbestos cloth to help the
problem.
What kind of baffling and other devices have been tried, and is there a
correlation to the size of the intake manifold and carb set-up that
contributes to this problem?
I sent Wynne this question, and have not heard back from him yet.

Subject: Re: Pietenpol-List: Corvair Flyers - long reply
In the summer of 2001, William Wynne, 'the Corvair Authority'
(http://www.flycorvair.com/) himself, had an engine failure in his own
Pietenpol. Note that according to the online aviation databases, William
holds an A&P but no pilot ratings. There were two in the aircraft and
the
other guy was officially the pilot. The plane went down and caught fire,
severely burning William. The investigation attributes the accident to
carbuteror ice. There's a write-up about the incident on his web site,
or
you can find the accident report on the NTSB web site.
In the last 20 years or so, the definition of 'experimental' has become
skewed to mean "a reliable airplane based on somebody else's kit or
plans".
Because of the proliferation of available kits, plans, engines, etc,
this
has become an expectation with homebuilders. At the end of the day, YOU
ARE
THE MANUFACTURER. Years back, I had a casual conversation at Sun 'n Fun
with
Bob Barrows, the guy who engineered and sells plans for the Bearhawk,
about
his take on liability. Bob's response was "Here's what I did, and
anybody
who wants to attempt to try what I did is welcome'. This approach
absolves
the experimental suppliers from liability, which in turn allows these
airplanes to be built at minimal expense. I'm not a lawyer, I've never
sued
anybody for anything, and I despise inappropriate (my definition /
opinion)
lawsuits. My concern regarding liability isn't about my ability to sue
somebody; it's about my expectation that anybody who engineers something
and
sells it should have enough pride in it to stand behind their work. On
the
flip side, that also means me, as the manufacturer of my homebuilt.
When I bought William's manual back in the mid-late 90's, he had me sign
a
liability waiver before he would give it to me (Does he still do this?).
In
this litigous society, I can't blame William for consulting with his
lawyer
first (In fact I think it was smart) before selling manuals, but it
didn't
instill a lot of confidence in me. I thought (and still do) it was
strange,
having never had to sign a waiver for anything when I bought airplane
stuff
before, but it certainly rams home the 'YOU are the manufacturer'
concept.
It also blatantly reinstates the classical definition of 'experimental'
with
respect to aircraft. Think about it.
I've seen scant few quality (my definition, sorry) Corvair installations
in
aircraft, but they also involved tons of work and skill; way beyond a
normal
engine rebuild and install. I suspect a good lot of the current crop of
Corvair folks are relying too heavily on William's work without
verifying
all the information for themselves, based on the volumes of 'William
says',
I hear at Sun 'n Fun every year and see on this forum, and some of the
shortcuts I've heard people are attempting. You are the manufacturer. Do
the
work. If you don't know how, get help until you know everything about
your
specific engine in your specific airplane. But please don't shortcut the
process because it's cheaper, either in money or in time.
Lots of folks would like to own an airplane for minimal or zero cost,
which
is really what this is about. If you could get a good A-65 for the price
of
a Corvair engine, would you really consider the Corvair? I have an
expectation that quality, reliable stuff is not going to be free, so I
expect to have to spend enough time, brainpower, and money to put a
reliable
airplane in the air. If somebody at the airport said "I just finished
this
plane and I only spent $400 for the whole thing", would you get in it
and go
for a ride with him? I'd be too busy looking for old gate hinges,
lawnmower
control cables, used dental floss and house paint. I'm not a
motorcyclist,
but a long time ago Bell had a one-liner ad for their helmets which
stuck
with me that said "If you've got a ten-dollar head, buy a ten-dollar
helmet". Not this boy.
Don't get me wrong; I do like Corvairs and I've owned many (3 right now)
since the late 70's. And I do my own work on them. You guys can wax
poetic
all you want about Corvair engines in aircraft, the Corvair 'Authority',
and
Corvair Colleges, and hopefully time will prove me wrong (sincerely).
But in
the interim and until the kinks are worked out, I choose to not be one
of
the lab rats in this 'experiment'.

Rob,
Not my text, I just cut and pasted this from a website:
------As the aircraft carburetor vaporizes fuel, it cools the intake air by
evaporation. The carburetor venturi also cools the air by adiabatically
expanding the intake air, known as the Joule-Thomson Effect. If the air
temperature drops below the dew point, moisture in the air condenses into
water droplets. Thus, water can be present in the carburetor even when
flying in clear skies.
Ice forms near the aircraft carburetor butterfly when water droplets
strike parts of the carburetor (typically the butterfly and venturi) that
are freezing. Freezing is determined by: the outside air temperature, the
temperature drop, and heat absorption from the engine. With the throttle
partly closed, such as in a low power descent, you may have a 10" Hg or
more pressure drop across the throttle butterfly.
The more gasoline the carburetor evaporates, the colder the carburetor. As
your engine idles at the end of the runway, little fuel is evaporating and
the carburetor's temperature may be above freezing. Adding takeoff power
increases the rate of fuel evaporation. Now the carburetor may be cold
enough to form carburetor ice. Your carburetor can get pretty cold. The
heat loss from evaporation of gasoline at the stoichiometric ratio creates
a theoretical temperature drop of 40 degrees F. The adiabatic expansion of
gas across the carburetor's venturi also lowers the temperature. Thus, you
could drop the carburetor temperature to freezing and form carburetor ice
at an ambient temperature of 72 degrees or higher. Stoichiometric is the
leanest possible mixture. At richer mixtures the ambient temperature at
which carburetor ice forms is even higher - Lycoming publishes a
temperature range of twenty to 90 degrees F. for carburetor ice.
Adding alcohol to gasoline dramatically increases the ambient temperature
where ice forms. Evaporating methyl alcohol creates a temperature drop of
300 degrees F. As a result, carburetor ice occurs over a wide range of
temperatures.
Your Continental aircraft engine forms carburetor ice at a higher outside
air temperature than your Lycoming engine since the carburetor on a
Continental engine absorbs less engine heat. Continental mounts the
carburetor to the intake pipes away from engine heat. Lycoming mounts the
carburetor to the oil pan where it absorbs heat from the engine oil. One
side effect of forming carburetor ice at a higher air temperature is that
the warm air holds more moisture than cold air; therefore, you have a
potential for greater carburetor icing with Continental engines than with
Lycoming engines ------
The Corvair WW setup is very similar to a Continental engine and carb heat
must be applied!
During test running of my Corvair on a test stand I could measure (and see
and feel ) the cooling effect right behind the carburetor.
It gets cold ! ...very cold at part throttle, the high humidity will cause
the outside of the intake manifold to get wet (water droplets) image what
happens on the inside.
I copied the setup that Mark Langford uses on his Corvair see
>>http://home.hiwaay.net/~langford/corvair/airbox/
Not his air box but only his heat pick up around the exhaust manifold.
My exhaust manifold is however not stainless steel (stainless steel is poor
conductor of heat) I used plain carbon steel and painted it black (maximum
heat rejection).
This works very well, the recommended 90 F temperature rise is easily
achieved.
The hot air is robbing a lot of HP, In flight I can feel the extra few
RPM/HP kick-in when I remove Carb heat.
Carb heat is not a problem in summer months in the Houston Texas area, as
temperatures are 90 - 100 degree but rest of the year the temperatures are
varying between 60 to 80 F and humidity is high year round.
I fly with carb heat on constantly, only during take off and taxing on the
ground I use cold filtered air.
Right before take off, during the run up I apply carb heat for about 1
minute with engine at 2500 RPM.

Hello,
I'm trying to reach Pietenpol folks to let them know about a wings & wheels fly-in event on June 11th at Lansing airport in Lansing, Illinois. I am with the (Ford) Model A Restorer's Club and we are working in conjunction with EAA Chapter 260 out of Lansing. We are, in part, celebrating the 80th anniversary of the historic Ford hangar at the airport, which was built by Henry Ford for his Tri-Motors. There is a good chance that we will have a Ford Tri-Motor at the event. There will also be other antique, modern, and experimental aircraft, as well as a large number of Ford Model A's (and some T's). There will be a pancake breakfast and lunch as well. It would be great to have at least one Pietenpol because of the obvious connection. Please visit www.jolietmarc.org (go to "Upcoming Events") for the full details, or feel free to contact me. Also, feel free to tell anyone else who may be interested (general public welcome).

The original system had a ventilation line on the 2 gallon header tank
to
avoid air in this tank.
However in flight this vent would create a pressure on the header tank
that
stop all fuel from the main tank.
The vent cap of the main tank is also in a low pressure area on the
wing,
which contributed to the problem.
I made some fix with a check valve on the header tank vent line ( air
allowed out but not in) and re-arranged the vent line to avoid excess
pressure.
I flew another 4-5 hours this way but was never comfortable with it.
A 2 gallon header tank gives you about 25 minutes of airtime at which
time
you get the urge to land.
I finally removed the 2 gallon header tank and replaced it with Piper J3
tank in the nose (12.5 Gallons) it shifted my CG forward which I
compensated with changing my exhaust system ( changed the cast iron
manifolds for a much lighter header system)
Been flying with that setup for more than 20 hours now and have had no
problems.
My Corvair is a '65 , 110HP Corvair conversion as per William Wynne
manual.
It is a very smooth and powerful engine, I would rate its reliability as
very high, very close to a Continental.
If it had dual spark plugs it would be an equal.
Still fly with a non nitrated Crankshaft too, although I have a spare
one
that is being nitrated.
If I had a O-200, C90/85 I would have used it,only because you do not
have
to deal with a 40 Test phase (25 hours if you have a aircraft engine)
Of course there is money issue as well, total expense on my Corvair was
6,000- US with all moving parts to new specs, I did not cut any corners
on
rebuilding the engine. (the crank in hindsight being the exception)
Furthermore I believe two more Pietenpols had to make a forced landing
last
year, both Continental powered, go figure..
It is very rarely the engine that causes a problem it is most likely the
systems around it that fail.

Hey all,
I was spending some time last night drafting out my fuse sides and ran into an
area that needs some clarification. The dimensions for the pilots seat back (22"
long) and the seat front (6" high) end up making a seat that just doesn't
"look" right. The rear seat support ends up very close to the bottom of the fuse
and the angle between the seat bottom and seat back is about 84 Deg. Does
this sound about right? or what have others done in this area? It would be easy
to raise the rear support an inch and add a wedge to the seat back to give
the seat a more "normal" look... Looks like it is time to build a mock-up and
sit it in front of the TV for a while to see what is comfortable.

Subject: RE: Pietenpol-List: Corvair Flyers - long reply
Rob,
Not my text, I just cut and pasted this from a website:
------As the aircraft carburetor vaporizes fuel, it cools the intake air by
evaporation. The carburetor venturi also cools the air by adiabatically
expanding the intake air, known as the Joule-Thomson Effect. If the air
temperature drops below the dew point, moisture in the air condenses into
water droplets. Thus, water can be present in the carburetor even when
flying in clear skies.
Ice forms near the aircraft carburetor butterfly when water droplets
strike parts of the carburetor (typically the butterfly and venturi) that
are freezing. Freezing is determined by: the outside air temperature, the
temperature drop, and heat absorption from the engine. With the throttle
partly closed, such as in a low power descent, you may have a 10" Hg or
more pressure drop across the throttle butterfly.
The more gasoline the carburetor evaporates, the colder the carburetor. As
your engine idles at the end of the runway, little fuel is evaporating and
the carburetor's temperature may be above freezing. Adding takeoff power
increases the rate of fuel evaporation. Now the carburetor may be cold
enough to form carburetor ice. Your carburetor can get pretty cold. The
heat loss from evaporation of gasoline at the stoichiometric ratio creates
a theoretical temperature drop of 40 degrees F. The adiabatic expansion of
gas across the carburetor's venturi also lowers the temperature. Thus, you
could drop the carburetor temperature to freezing and form carburetor ice
at an ambient temperature of 72 degrees or higher. Stoichiometric is the
leanest possible mixture. At richer mixtures the ambient temperature at
which carburetor ice forms is even higher - Lycoming publishes a
temperature range of twenty to 90 degrees F. for carburetor ice.
Adding alcohol to gasoline dramatically increases the ambient temperature
where ice forms. Evaporating methyl alcohol creates a temperature drop of
300 degrees F. As a result, carburetor ice occurs over a wide range of
temperatures.
Your Continental aircraft engine forms carburetor ice at a higher outside
air temperature than your Lycoming engine since the carburetor on a
Continental engine absorbs less engine heat. Continental mounts the
carburetor to the intake pipes away from engine heat. Lycoming mounts the
carburetor to the oil pan where it absorbs heat from the engine oil. One
side effect of forming carburetor ice at a higher air temperature is that
the warm air holds more moisture than cold air; therefore, you have a
potential for greater carburetor icing with Continental engines than with
Lycoming engines ------
The Corvair WW setup is very similar to a Continental engine and carb heat
must be applied!
During test running of my Corvair on a test stand I could measure (and see
and feel ) the cooling effect right behind the carburetor.
It gets cold ! ...very cold at part throttle, the high humidity will cause
the outside of the intake manifold to get wet (water droplets) image what
happens on the inside.
I copied the setup that Mark Langford uses on his Corvair see
>>http://home.hiwaay.net/~langford/corvair/airbox/
Not his air box but only his heat pick up around the exhaust manifold.
My exhaust manifold is however not stainless steel (stainless steel is poor
conductor of heat) I used plain carbon steel and painted it black (maximum
heat rejection).
This works very well, the recommended 90 F temperature rise is easily
achieved.
The hot air is robbing a lot of HP, In flight I can feel the extra few
RPM/HP kick-in when I remove Carb heat.
Carb heat is not a problem in summer months in the Houston Texas area, as
temperatures are 90 - 100 degree but rest of the year the temperatures are
varying between 60 to 80 F and humidity is high year round.
I fly with carb heat on constantly, only during take off and taxing on the
ground I use cold filtered air.
Right before take off, during the run up I apply carb heat for about 1
minute with engine at 2500 RPM.

I can see a lot of reasons not to use carb heat all the time. When you heat
the air going in, you reduce the density of the air and thus the horsepower.
At that point you need a higher power setting to produce the same amount of
HP burning more fuel in the process.
Worse than that you will lose more than just a few RPM's if left on at
takeoff. That power just might be what gets you over the tree tops.
Most installations when you pull the carb heat, you also by pass the air
filter. Lots of people think that carb heat helps the engine warm up faster
so they taxi out with carb heat on with no idea that the dirt the landing
gear is kicking up is being sucked into the engine without any filtration at
all. There is can work like sandpaper on expensive engine parts.
Everyone should have a solid idea of what carb ice looks like. Some
airplanes and engines are more prone to it. Someone asked about reasons for
engine failures on a few posts ago.
The last order I heard for the most common reasons for engine failure are
1. No gas on the airplane. 2. Contaminated gas on the airplane (water
trash ect) 3 Gas on the airplane, but the fuel selector on an empty tank.
4. Carb Icing.
There is a lot there we can do something about isnt it.

Manny,
All airplanes are and flying is dangerous, everything that goes up must
come down, controlled or uncontrolled.
The uncontrolled is the dangerous part.
Although according to NTSB most accidents are caused by the pilot. (they
always seem to be unable to keep clearance from terrain)
If properly build, the Pietenpol Air Camper is no more dangerous than a
Champ or Cub
It is just another Taildragger and not that difficult to fly.

Noise? What Noise? I had the engine shut off.
But I have many times thermalled with eagles with the engine on. I am using
an intake silencer, dual muffler, and a three bladed AERO prop with flared
tips to cut down noise.
Thermalling with two people I set the throttle to a flat cruise, hit a
thermal and turn to stay in it. Once I have 5,000 feet and I am flying away
from a ridge or over the face of a peak, I shut down and glide back to PABV.
What is a Pietenpol like as far as gliding is concerned, throttled back, not
engine out?

Hi Guy's,
First time poster here. My name is Dave and I'm near jacksonville,
Florida. I've been considering a Piet for quite sometime now mainly
because I'm the "nostalgic" type and I want to *build* vs. "assemble" my
own airplane...oh yeah...it's a two seater so I have the family's
*blessing*.
I intend to make some minor changes... nothing radical. I'm a pretty big
boy. I'm just looking for a tad more room in the rear seat mainly...but
I wont go into that at this time.
I did however, Find the"Interesting trim" thread...well, interesting. I
would like to throw an idea on the table for everyone's consideration
and if you wish, comment. What would you think of dual trim tabs, one on
each elevator half ? I'm refering to a very simple single "bowden cable"
type arangement with seperate levers in the cockpit to control each trim
tab. I'm wondering if in addition to longitudinal trim, a controlled
"rolling moment" may be induced by the seperate trim tabs that might
pickup a heavy wing or perhaps a out of rig rudder? Could the tab
positions be noted and adjustments to the rigging (All axis's) be made
to have a hands off airplane in cruise? Once the aircraft is rigged to
its own "groove" would the tabs be just that much more efficient? Could
the airplane be trimmed to fly hands off in all flight modes and
airspeeds.
I like a airplane that flies hands off once you have it setup. The
airplanes seem to like it too :-) The less I *bother* them...the better
they fly.
Anyway...what do you think? Is this too far out in left field?
Comments welcome

Others have probably made the changes you are thinking about. Get into
the archive section of the list and type in some key words like (Cockpit
door) (widen fuselage) (fuselage step) or whatever. It can give you a
lot of answers before you know what all the questions are.
I suspect that a bit of the discussion on trim recently was bouncing
ideas, rather lightly, on trim. You might want trim if you are running
a nose tank. However, I use a 13 gal wing tank with 4 gal reserve in
the nose. I have absolutly no need for a trim tab. The Piet flys almost
hands off at normal cruise. To climb, go to 2100 with the A-65. to
cruise level hold 2000-2050. To decend reduce to 1900.
It is a beautiful flying machine. Pure simplicity.

Went up for a nice 1 hour flight this morning with a friend of mine.
Just doing some sightseeing. Went south about 5 miles to check out a
fire. Had just turned and started to head north. Since, with a
passenger in the front, there is no forward visibility,,,,, when
something on the right startled me. Thought it was a plane in that
first milisecond.
It was a goose! Startled the crap out of me. He was flying the same
heading and altitude as me, but just 30 feet to my right. That would
have been something to have run up his tail.
Since that wouldn't be a forceful strike, more like a Deli slicer,
would it have taken out my wooden Sensenich prop?? Hmmmm

I went to a local ships chandler and bought some stainless steel bow
shackles. They were much cheaper and of better strength. Check out this UK
site for examples,

I drilled out the threaded part, closed up the gap a bit and used standard

I once heard a Grumman Goose pilot describe its glide characteristics
as: "If you lose both engines in the Goose, throw a brick out of the
cockpit window to see where you will land. After landing, run quickly
from the airplane to avoid being hit by the brick."
You and Galileo are right, if there is no air. In the presence of
aerodynamic drag, a tumbling brick will fall considerably slower than a
bowling ball. Now if you can manage to stabilize the brick to fall
narrow end first, it might actually go faster than the bowling ball.
Neither will fall as fast as a Pietenpol seems to with power off.

Subject: | Re: Pietenpol glide ratio |
From: | Hans Vander Voort <hans.vander.voort(at)alfalaval.com> |
All Goose, brick and bowling balls aside.
When I had my engine out I was at 2000 Ft AGL.
I landed easily on a field 2000 ft away while making a 180 in to the wind.
If no turns where made and wind was 0, I would expect a distance of 4000
ft.
Not knowing the optimal glide speed, I kept 50 MPH.
My guess would be a engine out glide ratio of around 1: 2 or 1:3.
More importantly the Piet is slow, even with the nose pointed down it will
take some time to get there.
With the throttle at Idle the glide ratio depends on what idle RPM your
running and the pitch of your prop.
A low pitch Prop and a engine at low idle (600) creates more drag than with
the Prop at standstill.

Subject: | Re: Pietenpol glide ratio |
From: | "Phillips, Jack" <Jack.Phillips(at)cardinal.com> |
I would agree with Hans. In my own forced landing, my engine was still
running and putting out about 1300 RPM, which extended the glide, but
was not enough to keep it in the air. I was at 1200' AGL, and was
coming down at 400 fpm. There was little wind and I made it about 2-1/2
miles before setting it down on a road. I also used 50 mph as "Best
Glide Speed". My guess is that with the engine out, the descent rate
would be somwhere around 1,000 fpm, which when combined with a forward
speed of 4400 fpm (50 mph), would give a glide ratio of 4.4:1. Not very
impressive, and on the order of the glide ratio of the Space Shuttle.
To get an idea of what that kind of glide ratio feels like, consider
this: In order to simulate the space shuttle glide, NASA uses a
Gulfstream IV with the thrust reversers ON to give a similar glide path.

All Goose, brick and bowling balls aside.
When I had my engine out I was at 2000 Ft AGL.
I landed easily on a field 2000 ft away while making a 180 in to the
wind.
If no turns where made and wind was 0, I would expect a distance of
4000
ft.
Not knowing the optimal glide speed, I kept 50 MPH.
My guess would be a engine out glide ratio of around 1: 2 or 1:3.
More importantly the Piet is slow, even with the nose pointed down it
will
take some time to get there.
With the throttle at Idle the glide ratio depends on what idle RPM your
running and the pitch of your prop.
A low pitch Prop and a engine at low idle (600) creates more drag than
with
the Prop at standstill.

I once heard a Grumman Goose pilot describe its glide characteristics
as:
"If you lose both engines in the Goose, throw a brick out of the cockpit
window to see where you will land. After landing, run quickly from the
airplane to avoid being hit by the brick."
You and Galileo are right, if there is no air. In the presence of
aerodynamic drag, a tumbling brick will fall considerably slower than a
bowling ball. Now if you can manage to stabilize the brick to fall
narrow
end first, it might actually go faster than the bowling ball. Neither
will
fall as fast as a Pietenpol seems to with power off.

After having fallen silent 541 days ago, the mighty A65-8 engine on the nose
of NX41CC has once again roared to life! Pictures (none of the engine
running though) at http://www.flysquirrel.net/piets/engine/engine.html .
After reinstalling the overhauled tailwheel unit and the new harness for the
left mag, I rechecked prop tracking and prop bolt torque and went over
everything one more time. I had added yellow tips to the prop for increased
visibility of the prop while running, and I put the fire extinguisher at the
ready, tied the tail and chocked the mains, temporarily installed the fuel
tank and put in four gallons of gas.
I pulled it through a dozen or so blades with the mags off, then turned on
the fuel and mags and gave it a go. The engine putt-putted after a few pulls
and then it flooded so I killed the mags and pulled the prop through
backwards, cut off the fuel, and tried it again... this time it ran but a
bit rough and obviously rich. The very best news is that the oil pressure
only took a few seconds to come up. I was worried about it being able to
prime and pump after sitting so long, but the pressure came right up to
30-35 psi and did well. I wasn't able to test the carb heat because after a
mag check, I quickly found out why the engine was running rich and rough...
the right mag (old "lunch box") was completely dead. I have miswired the
P-lead wire from the right mag to the ignition switch, so I need to correct
that. I ran the engine for about five minutes and the amazing thing is that
it started so easily and ran so well on only one mag. Should be a piece of
cake with both mags working, even without an impulse coupling to help
starting.
For now, I'm immensely proud and happy to hear the engine start and run, and
I got to work the throttle and get my hair all blasted by propwash. It was
a thrill.
I'm down to short rows now before she'll be ready to put the wings back on

Glad to hear we are all falling at roughly the same rate!!!!!
For a while I thought I had discovered some new quirk of the Pietenpols'
flight characteristics. I had experienced this "glide ratio" and during
the "maneuver" had decided to name the new aerobatic maneuver---"THE
FALLING STONE'
But, never the less, every ascent is exciting and every return to
earth, fills me with an Adrenelin Rush!
Just remember----Altitude and Airspeed.

Subject: | Covered wire wheels |
From: | "Don Emch" <EmchAir(at)aol.com> |
Walt,
In 1985, at the ripe old age of 13, I saw the Pavliga Air Camper (Sky Gypsy) in
Sport Aviation. I remember telling my Dad I wanted to build one of those and
that it was going to have the same kind of wheels. It took quite a few years
before I actually started building but when I did and when I got to the wheels
I copied Frank's. The covering is really simple. Getting the tires on without
messing it up isn't. Just cut a big circle of fabric a few inches bigger
in diameter than the rim with a hole in the center. Make a big 'washer' out of
aluminum that will fit over the hub and cover up the spoke ends. I cut little
pie shaped cuts and folded and glued those around to the back side of the washer.
Position the fabric over the hub and start glueing the edges around the
inside of the rim. Once both sides are done then glue a tape all the way around
the rim to tie the two sides together. This probably doesn't really need
to be done but can't hurt. Finish like any other fabric surface. I put an inspection
ring on the inside of both wheels. I leave it uncovered and placed
it near the air valve. With your tires already on the rim, you could probably
just let the air out and clamp the tire flat to get to the inside edge of the
rim. Wouldn't have to deal with getting the tire on without damaging the finish.
Tire change time though you'll have to deal with it. Mask the edges and
use lots of soap and a little cussing.
Hope you try it. Keeps from having to clean the spokes and you'll probably pick
up 1 to 2 mph!

Now steady on chaps, all this talk about bowling balls and bricks applies in
my opinion only to the glide angle that an idling Pietenpol would achieve.
In my experience (Continental A65 / Sensenich 72-42) the sink rate is not
that bad, and certainly such that one can climb in reasonable lift from
thermals, ridge and wave. You can't really then go anywhere without opening
the throttle because of the poor glide angle, but you can certainly get that
"Something for nothing" feeling that inspires a lot of glider pilots, and
there is also a good chance of coming across soaring birds in most
locations, which is indeed a fine thing.

Mike Hayes is right that you can get some thermal action in a Piet and on
many, many occasions I have
had to throttle back and push the stick forward to stop the ridiculous rate
of climb when I hit thermals.........but
with power at idle, you have drag city written all over a Pietenpol and the
only thing that will glide worse is
a biplane Jenny or old fashioned ultralight with cable braces and tubing
everywhere.
When the engine quits in a Pietenpol your circle of choices to land is very
tight....and it drifts with the wind.

the inside edge of the rim. Wouldn't have to deal with getting the tire on without
damaging the finish. Tire change time though you'll have to deal with it.
Mask the edges and use lots of soap and a little cussing.
Hope you try it. Keeps from having to clean the spokes and you'll probably pick
up 1 to 2 mph!

Subject: | Covered wire wheels |
From: | "Egan, John" <jegan(at)kcc.com> |
I've been on the fence whether to use Airdrome brand hubs because I believe=
they use 1-1/4" axles where I thought the Piets called for 1-1/2". Was it
Jack Phillips who cautioned the group on axle size and strength=3F My
apologies if I'm incorrect with any of this. I think the Airdrome plane
axles also slide an 18" sleeve inside the axle at each end to strengthen it=
which may be great, and I have not yet calculated the difference in weight
or bending strength. I would like to use these wheels too, but have not
committed to anything yet due to the above information. I also wonder what=
the weight of the Airdrome planes are compared to an Aircamper.
Wheel Covers: I've visited the "Old Rhinebeck Airdrome" a number of times
and I see many of the WW1 replicas there take a light sheet of aluminum, cu=
t=
it appropriately so it kind of rolls into a shallow cone shape to fit over=
the outside of the wheels. The covers kind of fit loosely over the wheels
and can be easily removed. Something to consider... You guys who fabric
the wheels do a great job.
Looking for thoughts on this subject (axles).

Hiya gang,
Another Piet project is off and running. Ready to start building wing
ribs and I discovered a "ton" of 1/4" X 1/4" douglas fir capstrip
already ripped and ready to turn into ribs. I didnt know I still had
this until I was cleaning up the shop a few days ago...so, you know
where this is going...so, what do you think. Can anyone see any problems
with using 1/4" capstrip on the Piet wing? I should also say I'm using a

Welcome Dave,
What does the GN-1 use for capstrips? I've heard that 1/4 x 1/4 is used
on lots of other planes, and that the 1/2 x 1/4 specified on the Piet
are a little overengineered. Others will tell you to stick to the
plans. Where in Florida are you located?

Hiya Ben,
Thanks for the welcome. I'm NW of Jacksonville near a little two horse town
called Callahan.
You're right. Most all airplanes I've seen plans for used 1/4" X 1/4"
capstrip. Even with spruce 1/4" X 1/2" seems heavy duty and I intend to
build mine with fir. Spars will be laminated fir as well and may be 3/4"
thick with 1/8" ply plate doublers where needed to maintain proper diminsion
associated structure. Still havnt decided for sure yet.
I may extend the wings a couple of feet which will reduce wing loading a
little and help on a hot humid day down here.
Rib nose blocks will be 1/4" marine fir or Okume. Whatever I can find
locally. As I mentioned .020 aluminum L/E and trailing edge will be aluminum
as well.
I just have a good bit of this stuff on hand already and figured I would use
it. I'm not really a "purist" but safety is first and foremost and really
like this forum. Seems like a great bunch of people that really know there
"Piet's"
Thanks for any comments or info.
Dave

Dave,
My Piet is not flying yet, so consider my advise accordingly. I would not reduce
the size of the rib capstrip unless I had an aero engineer run the numbers first.
Yes the 1/2X1/4 is larger than most wood truss type ribs, but the Piet and
to some extent the GN1 wings are designed differently than other wood wings.
I think the Piet rib is used to carry more of the loads than some other planes.
Just my 2 cents.

Dave,
Welcome aboard; we can always use some additions to the Florida Piet 'herd'.
I am on Tavares,FL; about 35 miles NW of Orlando and I built my bird of Doug
Fir for all the structural stuff. Also used 3/4" laminated spars.
I concurr with the theory that Bernard built 'hell for stout'. I made my
longerons 15/16" vs 1" and if I were to do it over I believe I would go with
7/8". I don't think you are too far out to think about using 1/4" square cap
strips. After all thats what Pitts and a lot of other planes have used. I'd go
to 3/8" caps no problem. You could make sample test ribs, a 1/4" and a plans
1/2 " and do a static destructive load test just to get an idea of what the
feasibility would be.
I used to fly with the Navy Flying Club at NAS Jax and I used to take
students over to the grass strip at Callahan frequently.. At Thomasville a few
years
back there was an interesting Piet from Callahan; it had an aluminum covered
turtle deck.

Using 1/4 X 1/4 instead of 1/4 X 1/2 capstrips will save a little over 2
1/2 pounds if using spruce and a little over 3 pounds if using douglas
fir.
I know weight savings is important but, personally, I would look
elsewhere for weight savings.
Additionally, some info says to use 1/4 X 1/4 if your hp is 65 or less.
Other than the slipstream, I don't see a connection between hp and
capstrip size.

Before today I have never actually seen a completed Pietenpol. I emailed Walt
Evans to see if I could take a look at his plane since I was driving out to New
York City and he's in New Jersey. Being the nice guy that he is he extended
an offer to meet me at his hangar. It was drizzly and WINDY and he came out
and showed me around his plane. Can't say enough about what a nice job he's done.
I also can't say what seeing the finished product means to somebody who
just has a bundle of wood, T-88, a rib jig and a couple of ribs and an easle with
plans resting on it. Wow!
After talking for quite some time I thought we were wrapping up and he asked if
I was interested in a ride. The wind had died down and conditions had improved.
I didn't want to impose but at the same time I didn't want to pass up an
opportunity like this. So I took him up on the offer. Getting into the passenger
place helped me brush up on long lost jungle gym skills and then, there I
was, looking at his passenger panel. I couldn't believe it was happening. He
fired up the Continental, taxi'd out, and before I could say Holy $#*% we were
in the air and climbing!
Right then and there, it hit me. This is what it's all about. Definitely an experience
that I'll never forget and a catalyst for my project. I knew it would
be fun, I just didn't know how much. Like I told him, I can't remember how
many times I said "Wow!" during the drive home.
Thanks Walt!!!!!

You need to track down a man named Pat Green. He has a Piet that he
keeps in the Jacksonville area somewhere. He extended his wings for
added lift, as he put it to get over the pine trees at the end of many
Florida airports. Its powered by a Corvair with the BP conversion
complete with blower fan and has been flying since the 70's. I can send
you some pictures of his Piet directly if you are interested. I wish I

I use a corvair it is my risk. Perhaps we should let this subject rest?

Subject: | Re: Corvair Flyers / apology & clarification |
I agree!
The Internet has only been around for 14 years now. Postal letters have been
around for hundreds of years. Although many folks tout the so-called
advantages of email and websites, they simply don't have the track record
that serious communicators demand. In fact, I knew a guy who got the
Internet and joined an email list and within a month, he started to get
messages he didn't like. He sold his computer, and has been happily using
the US Postal Service ever since. You're free to do what you will, but I
don't want to be a guinea pig in some techno-geek's big worldwide social
experiment.
Seriously, this discussion has been annoying me a bit to watch, though it's
nothing new. I do appreciate Jim publicly clarifying that he wasn't trying
to malign William, which is more than usually happens. But some perspective
is in order here.
Obviously, nobody's forcing anyone to use an engine they aren't comfortable
with. I'm personally sold on the Corvair, as I've come to know William and
the Hangar gang well enough that I have faith that they are honest and
straightforward in their dealings and that they are right when they say that
I am capable, with their help, of building a satisfactory Corvair-based
aircraft engine for my personal requirements. I have heard them tell people
both what this motor both can, and cannot, do, and if anything I've seen
them consistently UNDER-sell the capabilities of the Corvair rather than
OVER-state it to try to sell products. In my experience, they've never, ever
encouraged folks to do anything blindly just "because they said so"... they
have always been willing and able to back up their recommendations with
sound reasoning. Most importantly, this is most often based on significant
amounts of actual flight experience, not theoretical calculations or single
tests as some other folks will use to "prove" their products. If they only
have one or two data points, or none, they will make sure you know that
fact. They also have consistently encouraged people to learn and understand
for themselves WHY they recommend to do something, or not.
In my opinion, anyone who says to do something "because William says so" is
missing the point somewhat, but they generally do so because they have found
that he has actually earned the right to be considered an authority on the
subject. This is because he really has tried most of the ideas that people
have asked about, and refined the good ones so that anyone could use them.
While I've heard folks criticize Corvairs before and even pull out some
examples to "prove" their unworthiness, they never seem to mention the
thousands of failures of Lycomings, Continentals, Pratt & Whitneys, etc.
installed by "qualified" folks for comparison. 98% of the "examples" are
things heard from friends of friends, etc. From the folks I've personally
talked to, emailed, and read about who have actually BUILT their own
Corvairs and can thus speak with some authority on the matter, it would seem
that nearly everyone who has followed William's advice has ended up quite
satisfied, if not extremely happy, with their Corvair installation. Most of
the occasional problems I've heard of have been caused by things that
William has specifically and publicly warned against doing, or happened
before he even started his research on the subject. In short, folks who
follow WW's advice tend to have a high chance of success with their Corvair
engines.
I don't "deify" William or anyone else, nor do I have any personal stake in
this discussion other than I consider the Hangar Gang to be friends, who
happen to be "the" experts on the engine I will build in the (hopefully
near) future. However, I can honestly say that the Corvair Hangar Gang, to a
person, set an excellent example of honesty, enthusiasm, helpfulness, and
fun that I wish was present in everyone in aviation. This seems to have
rubbed off on quite a few others (or perhaps it just attracts like-minded
souls) throughout the homebuilt community, who then share their enthusiasm.
I don't know why, but this seemingly attracts the occasional ire of a few
folks who'd rather complain about a subject they rarely seem to have any
first-hand knowledge of. I'm no engine expert myself, but if you ask me,
even if you don't choose to fly a Corvair yourself, you should have a
healthy dose of respect and appreciation for the many positive contributions
that the Corvair folks have made towards furthering recreational aviation.
We need a lot more folks like them in the aviation world.
BTW, most homebuilt companies now require a signed legal release before
selling plans or products. This is simply a factor of today's out of control
legal system, NOT a lack of faith in their own products. It isn't the plans
purchaser they are worried about, but their survivors's lawyers. It doesn't
matter whether the accident really had anything to do with the manufacturer
or not.

Hi Guys,
For those of you running A-65s I have a question for you. In these following conditions
what would you expect for initial rate of climb? Field elevation 1100',
80 degrees, full fuel, and solo. I am right around 900lbs in this condition
and am just wondering what you guys would expect for climb.

I haven't got a ROC instrument, so I just put the ASI on about 50 mph, and
live with whatever the rate of climb is. I am at 960 lbs, solo, with 20 gal
full fuel, field elevation is 1360' at Cook Field, turning close to 2000 rpm.
I
suspect it is somewhere around 200 FPM, and is never above 300 FPM. My ROC
has improved a little bit, since I reworked my prop, and now I can now get full

the leading edge of the wing, in my mind, I get better performance, and the

My plane is just under 900lbs loaded as you described, and with my

closer to 200fpm with a 150lb passenger...that is a little scary to me.

gleaned from previous emails and transponding with Tennessee props.About
658.00 Cnd for mine.She's a beauty.

The other critical piece of information for comparison is what type of
prop
you have on the airplane. Might not be the engine at all but you might
need
a different prop to get the most out of the airplane

Mine's a little heavier. Solo it weighs about 1,000 lbs. Climbs at 300
fpm (I have a VSI). With a 160 lb passenger added it climbs at about
250 fpm.

I'm right in there with Chuck. 18.9 gal and 200 lbs of me puts me at
990 lb. Field at 900 ft. Something arount 300 fpm.

Hi Guys,
For those of you running A-65s I have a question for
you. In these following conditions what would you expect for initial
rate of climb? Field elevation 1100', 80 degrees, full fuel, and solo.
I am right around 900lbs in this condition and am just wondering what
you guys would expect for climb.
Thanks,
Don Emch
I haven't got a ROC instrument, so I just put the ASI on about
50 mph,and live with whatever the rate of climb is. I am at 960 lbs,
solo, with 20 gal full fuel, field elevation is 1360' at Cook Field,
turning close to 2000 rpm. I suspect it is somewhere around 200 FPM,
and is never above 300 FPM. My ROC has improved a little bit, since I
reworked my prop, and now I can now get full rated rpm (2300 rpm), in
level flight, full throttle. If I wax the prop and the leading edge of
the wing, in my mind, I get better performance, and the bugs wipe off
easier !!

Does anyone have there build times broken down by section that they would
like to share? I'm curious about how long it takes for the fuselage, wing,
empennage, gear, covering, etc. Thanks

Boyce: I find build times are kind of irreverent. Building my center
section seemed to go on and on for ever, and ever. When I framed up a
wing it went so fast that I thought I could have both done in a month,
Then I got into the small details which slowed things WAY down. It took
about a month to build that one wing, and it was spread out over two
summers. My whole project was to be a 2 year thing, I'm into year 8!
Bottom line..don't sweat time, just get started and keep plugging away.
I'm glad I didn't try to build to a time schedule. I would be building
an imaginary Piet in a padded cell some whare. Leon S.

Thank you guys very much for all the rate of climb info that you shared. I timed
(no vsi) my climbouts the other night and got to wondering what others were
seeing. I am spinning a Hegy 72 X 44 prop. I seemed to be timing about 350
fpm. I notice a real difference between 45 degrees and 80 degrees. I've noticed
a difference in everything else I've flown but the Piet seems to be fairly
sensitive to temps. It was a little breezy the other night and the Piet seems
to be sensitve to that too. I'm sure it's just me not really used to flying
something so light. Just a ball of fun to fly though!!! :D

Pieters,
Does anyone have any experience with croming 65 cont cylinders. Mine
are .015 over and pretty much to the limits and I wonder if new ones are
aviable, if crome is the best way to go and which type is the best and what
are the cost.
Also is anyone flying around with the cg at 30 percent and how does it
fly. I could lose some weight but you know how that goes. Ken in rainy

Ken,
Re CG, as you burn off fuel the Cg will be moving back with you in the
plane. Even a traditional NACA wing does not allow over 32% aft cg.
The Piete wing as designed doesn't allow that far aft without mucho
problems with needed lift from the tail feathers, and loss of control.
highly recommend a) cut back on the big Mac's (my problem), b) add some
lead to the engine compartment if your gross weight is ok with added
lead. Aft CG dangerous place to be. I designed my Piete with an 0-235
extended forward and battery forward of empty cg and still need to be
sure not to fly with less than 5 gal of fuel so not to go beyond 32% of
chord. My Piete has Aeronca wings, more forgiving than original Piete

Chroming was a way to go for a while, but it seemed to have some
problems. I would check with Superior Aircraft as they have cylinders
for nearly every engine that was ever built. They would probably
overhaul yours of have an exchange set waiting to ship to you.
The worst engine problem I ever experienced was due to a broken rocker
box in a Cont 0 200 (Guys trust me they don't run well on 2 cylinders,
but it ran) and it was replaced with a Superior cylinder. That section
had been greatly beefed up and was much stronger than what came from the
factory.

When I built my A65, my cylinders were worn to the limits. I looked into
having them chromed and rebuilt. Cost was $550 per cylinder. Then I looked
at Superior's Millenium cylinders which were $800 per cylinder, but you got
new pistons, new rings, new valves, new valve springs, new valve seats, new
rocker shafts and new piston pins. With the rebuild you have the
questionable durability of the chrome, plus everything is still 60+ years
old. I bought the Millemium cylinders.
An added benefit was the increased accuracy of their casting process for the
pistons. I weighed all reciprocating components to get the engine mass
balanced as well as possible. All four of the new pistons were within 1
gram of each other. The original pistons varied by as much as 10 grams.
The engine runs extremely smoothly.
