Hi, Grant,
I've seen all the replies you've had to this post and I can't for the
life of me understand why everyone makes such a simple thing so
difficult (if I'm missing something here, I apologise in advance). I
suggest that you do what I did when I decided to rebuild my 701 nose
gear - buy the bits you want from ZAC!!!. In upgrading mine to the
latest specs I simply ordered the bearings from ZAC and they arrived a
few days later (correct size, thickness and 2 inch hole already
machined). Didn't cost much and saved a hell of a lot of shagging about.
Cheers,
Phil M

Hi Dan,
It's mainly the bottom bearing -- but the top may be slightly as well. I
looked at the main gear more closely yesterday and they seem fine... maybe
also a function of my heavier engine and so more 'working' in the nose strut
during taxii?

Even with punched holes, aren't these holes just pilot holes? You still
have to drill them to the needed size. I really don't see a problem here.
It just saves a lot of measuring and makes for nice straight rivet lines.

Definatly on the discharge (outlet) side...See the discussion about not
sucking fuel thru restrictions...Get a spring loaded check (mine have 0.3
psi springs) absolute max should be 1 psi spring. The springs positively
prevent backflow but you lose the spring pressure in the forward direction.
I thought about the crowbar circuit but decided against it...not sure I can
remember why?..Probably cos I've never personally heard of an alternator
failing that way.

How about the "Crowbar" O.V . protection mentioned in the Aeroelectric

Also where would one place checkvalves to supplement the ones on the Facet
Pumps? Intake or the outlet side? At the pump?

Free advice from the flying lawyer (and worth what you paid, cuz this isn't exactly
my area....)
Larry has this basically right, although of course I will pick nits.
Under U.S. law, generally "copyright" is a noun, rather than a verb. The person
who draws or writes something original automatically has "the copyright," quite
literally the right to make copies (and, crucially, "derivative" works), unless
that person has made other arrangements (i.e., is creating a work for hire,
has assigned the copyright to someone else, etc.). This is true whether or
not you put a little (c) on it, in fact. You can also register a copyright
-- some people rather loosely refer to this as "copyrighting" -- but that really
doesn't matter much for our purposes.
So, we can probably safely assume that Zenith or Chris Heintz has the copyright
in the plans for the 701. Now if somebody sat down and copied those plans, or
used those plans to make his own plans -- i.e., if somebody created plans that
were a derivative work -- you would likely be looking at a copyright violation.
Sort of like if I wrote a book using the Superman character, I'd be making
a derivative work and violating DC Comic's copyright in the Superman story
(unless my book was a satire, or fell into some other exception). There might
well be trademark issues there also.
Meanwhile, I am fairly certain of the following: unless there is a patent at issue
(and I'm not yet aware of any here), you can reverse engineer someone else's
product and then sell your own product just like it. For example, absent
a patent, I can go out, take measurements of a Lexus, and build my own car just
like it. I can't use copies of the Lexus plans to do it (a copyright issue),
I can't put a Lexus logo on it (a trademark issue), and there may even be some
aspects of the Lexus that I can't replicate because they constitute "trade
dress" (sort of like the shape of a Coke bottle), but aside from that, I can build
a Lexus.
By the way, that "absent a patent" condition is a BIG one. In real life there
are probably about 6 zillion patents covering all sorts of stuff in a Lexus, so
you would be in DEEP patent doo-doo if you tried this stunt.
Anyway, my long-winded point is that the Savannah may well be perfectly legal even
if it is *exactly* like the 701. The ethical issues are another matter, and
I have definite views about that, but I think I have the law right.
How many times you can use legit 701 plans to build a 701 is also a separate issue.
It may be limited by your contract with ZAC (if any), so I won't venture
an opinion there.
Cheers
Doug G.

You are correct, the plans are copyrighted. Which means you can't copy the
plans without their permission. Has nothing to do with how many times or
what you can use them for. I bought the plans with the rights to use them
as I please except to copy or republish without ZAC's permission. I don't
remember any contract stipulating the number of times I could use the plans.
I have no idea how many parts are interchangeable. With the pegastol wings,
there are none that I know of. I looked at the Savanna real hard and there
are a lot of differences/improvements, so I really doubt too many parts are
interchangeable.

--> Zenith-List message posted by: ZSMITH3rd@aol.com
The fuel tank, vapor lock, selector valve horse has been badly mauled.
Beaten to death is more correct. However, is there anyone on the list who
has built and flown a 701 with only
the firewall-mounted "header tank" as in the earlier plans BEFORE the wing
tanks became either standard or an option?
Reason for the question is that the bottom of the tank, and therefore the
gascolator, is below the bottom of the engine. This arrangement would then
depend on the Rotax engine-mounted fuel pump being able to suck fuel uphill.
This
is the method ZAC shows on plans up to about 2001. Comments solicited.

Like I said I have two batteries seperated by a diode so if the alternator
goes away I have a few hours left.
Alts usually fail by going dead rather than going O.V....At least that's
been my experience...I'm more mechanical than electrical though.

One alternator and one voltage regulator? and no engine pump or gravity feed
system! Trees! Even airliners have have total electrical failures, but
engines keep running because they suck fuel from the tanks. A total
electrical failure is not beyond the realm of possibilities.

Yes but its not that simple Dave....My electrical system is completely
redundant apart from an O.V. situation.The crowbar circuit would presumably
fix this if you so desire..My main batt/alt could short to ground catch fire
and melt the plane but the other pump will still keep the engine running for
over an hour from the second battery, which of course also runs the second
ignition system...

Think total electrical system failure. And think that if one pump can fail,

Vapor forming between the final pump and the carb would just move up the
Carb bowl and percolate out. No Problem there. A hot line between the tank
and the pump is the source of potiential vapor lock.

It is easier to use a push broom handle. Just lay the handle across the sheet
and turn the broom end like a crank. When all the plastic has been rolled up
on the handle, take a pocket knife and slice it off. I don't think the plastic
wrap will protect against corrosion. I have seen terrible corrosion on
aluminum with the plastic left on too long.

| Subject: | Is the Savannah a copy of the 701??? |
--> Zenith-List message posted by: "Thomas F Marson" <tmarson@pressenter.com>
This has been beaten about a lot the last few days.
As ZAC shows on their website several different European manufactures are
building airplanes to the general outline of the 701..
The pictures leave no doubt of that. ( An aside --- there have been many
"knock offs" of he Kitfox general outline too in the USA and most come from
Idaho, Oregon Washington area) In fact the Kitfox was a knock off of the
Avid. In each case the planes are different considerably but they do look a
lot alike. Like several kids from the same family resemble each other they
are different.
Back to 701 / Savannah. The two airplanes have a general outline similarity
and in many ways it appears share a lot of the same dimensions. The changes
(improvements) made in the Savannah are really quite significant.
1. VISUAL IMPROVEMENTS.
After considering the 701 design for many years as a potiential but
reluctant customer, the 701 to many has many unattractive visual features,
the lowered cabin/raised wings being one, and the whole tail assembly the
other. I am not a lurker, but a doer. I have built 3 airplanes since I first
considered the 701. I am still attracted to it and repulsed at the same
time. The Savannah has corrected many of the design elements that have alway
held me back.
2. PRACTICAL BUILERS IMPROVEMENTS.
After building 3 planes, one being an RV 6, with its 14,000 rivets, holes,
deburring, bucking etc, and at age 74 I dont have the will to build another
such kit. The Savannah comes along and from what it appears has done the
"heavy lifting" for me on the endless detail.
3. PERFORMANCE IN THE AIR
The takeoff/landing performance is the real strong point of the 701. Its in
air cross country speed is on the low side if XC is important, to me, it is.
Sometimes I just want to be in the air flying low and slow and sometimes I
want to go somewhere. The Savannah appears to claim the same low takeoff
speeds but with higher tops speeds. Are these claims factual? Only someone
who as flown both and recorded factual data can say.
4. SAFETY OF THE DESIGN.
Only someone who has used a critical experienced eye will be able to
evaluate that. That person must be completely familiar with the 701 and the
Savannah. Not just on an overall level but on a fitting by fitting shape and
thickness but strength of materials view.
Tom in Wisconsin.

I have a semi-idiotproof system on my 601HDS. I have the 16 gal main tank
and 2 7.5 gal wing tanks. I have a check valve on the outlet of the main
tank, 2 Facet pumps on the wing tanks feeding a tee to a transfer valve to
another tee below the main tank check valve. In flight, all I do is flip the
DPDT center OFF switch to aux tanks and the pumps alternatly feed directly
to the engine. The other side of the DPDT turns on anothe Facet pump in
paralell with the engine pump.( I can't put the wing and boost pumps ON at
the same time which might flood the carbs.) A timer circuit switches the
wing tank pumps about every 8 minutes. It also operates a red/green LED to
show which tank is feeding. The LED blinks if the tank is empty and then
switches back to the other tank. I start the engine, switch on the aux
tanks, open the valve and go fly until I notice the blinking LED. Then
switch off and close the valve.There some GOTCHYA's as it is only semi-idiot
proof (they keep making better idiots) but you wont hear the sound of
SILENCE until there's no fuel left. You MUST keep the transfer valve closed
when the wing tanks are not being used. I may put in an electric valve. .
I am writing an article for KITPLANES laying out both the electronic and
mechanical details.

Yes, you may reverse engineer under some conditions. Software, for example,
has specific rules about those conditions.
Two more airplane examples, Aviat admits that they were unable to obtain the
type certificate for the super Cub, so they designed a plane, the Husky,
with the same functionality. No interchangeable parts, new design, similar
look, flying prototype, did not copy the blueprints for the cub or take
measurements.
Throp builders tell me that the first Van RV series were very similar to the
T-18, but again, no interchangeable parts, did not copy blueprints, new
design even if similar, built a prototype.
I am unaware of anyone who has accused Aviat or Van of copying their
designs.
I am certain that there are no patentable aspects of the CH701.
I will venture the opinion that one set of plans allows one authorized
airplane and no more. Interestingly, if you are an authorized builder and
your plane is destroyed, you may build a new plane without an second
authorization. That is, the rights to one plan do not expire if the
physical airplane is destroyed.

Someone may have some experience with this .
Are the finger strainers in the tank adequate for
filtering the fuel good enough to protect the facet
pump. Facet instructions say there should be some
sort of filter before the pump.
I am hoping I can get away with this because
I want any extra filters after my gascolator.

Just one idea we learned from the old pilots here, We always fill the
tank(s) of our planes and UL's using a funnel with a "Chamois" (dont
know the name in english, probably the same) is a piece of deer leather
cloth, this keeps all water dirt and debris from entering the tank. A
plastic foldable funnel (with a Chamois of course) travels with the
plane in XCounties.

The normal fingerstrainer is to keep bugs and leaves etc from plugging up
the bottom opening of the fuel tank. I am almost certain that it would not
qualify for " a filter" for the Facet pump.
For the record I have dual parallel Facet pumps on my plane and have no
other filter. I have had no pump failures in 8 years and 350 hours. Tom In

Yes but a filter plug on the discharge of a pump will show up as a gradual
decrease in fuel pressure. The engine will keep running even at zero
pressure at the carb.
If you put the filter before the pump it will show up as a sudden flow
stoppage (and therfore engine stoppage) without appreciable warning. In
other words the negative pressure on the downstream side of the filter will
degrade (as the filter blocks) until the suction exceeds the vapour pressure
of the fuel...Then you get instant vapour lock.
Just put the screen (in the tank) before the pump, nothing else.

| Subject: | Plastic protection, fuel pumps and header tanks |
--> Zenith-List message posted by: "Christoph Weber" <Chrisoz@gmx.net>
Well, I sat down in front of the computer on April 1st and decided to write
something silly, didn't expect it to pop up on the digest of March 31. This
international dateline in the pacific stuffs things up, on the other hand here
in Australia the new year is still nice and fresh when it comes our way,
while it is sort of handed down around 3/4 of the planet by the time it hits the
USA ;-)
But I sure hate that plastic stuff, especially on the wing skins!
In regard to the neverending fuel pump discussion, my last 601HD with Subaru
had leading edge tanks, no header, a pump in each wing next to the tank,
seperate fuses for those pumps. As a backup a master pump, electric, hooked up
to the ignition circuit, with it's own fuse. If my electrics go I can switch
off the master, and just keep her flying on ignition and master pump, if
everything goes there is the BRS where the header tank would have been. Paranoid,
but safe. Heavy, too!
My current baby gets the normal header tank and one electric pump to back up
the 912 mechanical pump. It will not be vented through the cap, but via a
seperate fitting and a hose through the bottom of the plane, no smell. It is
KIS, lightweight, sightgauge beats the inaccurate electric tankgauges.
I repaired a friends Zodiac a few month ago, he had torn off his
undercarriage, and in the process stove the firewall in with the nose leg. When
we took
the header tank out the tank was cracked at the bottom, but only trickled
fuel. Lucky, lucky, lucky!
The nosewheel leg acts like a lever, and it pivots around the upper bearing,
pushing the lower bearing and firewall in. The upper bearing moves forward a
bit, but is fairly flexible, and the floor of the cockpit caves in, pushing
the skin and the heel support upwards. Beyond a certain point the tank is in
harms way as the leg bends the firewall inwards, and 6061 T6 tanks crack,
because of the tensile strength they don't deform softly. The nosewheel is like
mounting a can opener to your plane!
My 601's have all been taildraggers, lighter, faster, safer, and really easy
to handle.
My first 601 with 912 and GSC prop maxed out at 110 miles, no fairings,
cruising comfortably at 100 miles.
If you consider building, do consider the taildragger!
Cheers from downunder,
Chris

Actually I think you will find that the modified Playboy IS the RV-1 (saw Ted flying
it recently) the RV-2 was a glider project that never got finished. An
interesting side note, before the RV4 was introduced, I along with about 5 others
tried to convince Dick to bring the RV6 in first. His comment was one of the
FEW times he's ever missed the mark. " The side by side market is saturated
with the T18, Tailwind, Sidewinder, Mustang II and others The tandem configeration
is a bigger market, plus I like that configuration " He also said he
would never do a 4 place, as he says "we reserve the right to get smarter"
And the rest is history. Low&SLOW John

If you want overvoltage protection you can buy 800 watt transient
voltage suppressers from Digi-Key for $0.56 each.

| Subject: | Dynon Avionics EFIS-D10 |
--> Zenith-List message posted by: "Larry Martin" <earthloc@att.net>
I am about to purchase an EFIS-D10 from Dynon Avionics. They have a concern about
the pitot tube on a slated wing. I haven't built my Pegastol wings yet and
can't find any reference to the location of the pitot tube in the instructions.
I would think it would be in the same location as on the Zenith 701 wings.
I know it's on the left wing but I can't tell how far the tube extends past
the slat. I also have Zenith drawings but it only shows the tube on the wing
and doesn't reference it to the slats. I need to know if it extends past the
slats and how well it works.
Take a look, www.gyrostabs.com

Hi LIst,
I have a question for anyone who uses a Microair 760 radio. I just finished
wiring mine up in the panel and the volume isn't very loud unless the
signals are quite strong. With the volume all the way up there is little
background hiss or sizzle even with the squelch fully open. When there is a
weak signal I have to turn the volume all the way up to hear it comfortably,
but when a stronger signal comes on the channel it will blast me out of my
sox. The volume seems proportional to the signal strength to a greater
degree than any radio I have experienced and I've been a ham radio operator
for 45 years. The sensitivity is good and I can hear a lot of distant AWOS
signals that other radios don't receive. Transission is fine and I am told
the voice quality of transmitted signal is good.
Anybody else had this problem? It's an earlier radio that I have had for a
couple of years and maybe there is a mod?
Thanks in advance,
Ron DeWees
