| Subject: | 25 vs 40 Hours Flight Test Time |
First, HAPPY NEW YEAR to all!
Doing some hanger flying this morning at the local EAA hanger, the subject
of flying off the initial hours on an ELSA came up. There seemed to be no
clear consensus of what determined a "Certified" engine/prop combination. I
have Googled all over the place this evening, and am now even more confused
than I was!
I have visited lots of locations, as well as the FAA pages. The best I can
come up with is that it is up to the judgment of the DAR, who signs off on
your project as airworthy. I did find some information that says the DAR
may be willing to listen to arguments about 25 hours of test flight time,
provided you can prove your engine/prop combination has been FAA approved on
other aircraft, in the same combination.
I also noticed that there are both approved and unapproved RoTax 912's out
there. One of the guys this morning said he was flying the unapproved one
so had to fly off 40 hours before he could take up a passenger, but no one
seemed to know what the difference was in the engines. The only difference
he came up with was a several thousand dollar higher price tag on the
approved one!
I am building with the Jabiru 2200A, the latest version with hydraulic
lifters, and using a Sensenich W62HJ-36 prop.
How do I go about finding out if this combination has FAA approval? I
believe that combination does exist in some of the recently approved LSA
that are coming on the market. Does that constitute approval?

| Subject: | Ron's question on floats |
Hi Ron, yes the floats are now made in Kitchener/Waterloo area. For the
U.S. residents we plan to have stock at Flight Crafters in Florida and
Quality Sport Planes in California later this year. By doing this we
ensure fairness to all North American residents. Were not excluding
anyone, we will also ship overseas and we are in discussion with a
dealer in Europe to also stock our floats at a later date.
As for the DVD, we had great fun helping HomebuiltHELP in it's
production. At the end of the video we show you the reason why we did
it. The video was shot during a weekend and there are things I would
like to have emphasized more and some less. Moreover, it is only a guide
as there are many ways to produce parts for your plane. We just
emphasized what the average person is capable of with small shop tools
and a little time. Is it worthwhile? I believe so, for a person just
starting that have never tried working with aluminium before it saves
about two years of learning. For those who have been doing it for a long
time, you may find a few tidbits and a lot of laughs. Yes even some head
shaking :-)
We filmed it in a realistic crowded environment and not a spotless
hanger, using home shop tools and some tools we made ourselves (which at
the very beginning you see me repairing my brake which David broke the
first day of filming! But I got even! When you see him using the bandsaw
remember he is trying to make it look smooth and easy to cut a piece of
aluminium, he didn't know that the evening before I installed the
dullest blade I had, their was almost no teeth left on that sucker!) Yes
we had fun, David and I work rather well together, best of all is the
fun we have.

On this note... When I first started building I saw the picture of a 601
on floats and loved the idea. I think I asked about it at the time and the
responses I got suggested it was not the best of ideas. I know it is not
overly common to put a low wing plane on floats, but I just can't shake the
idea. (I don't even have a seaplane rating, but it is high on the flying
wish list.)
With this thread, I'm just hoping for some people to throw out
ideas/experiences that might be relevant to such an idea.
So...thoughts, ideas, experiences?

| Subject: | Re: Fuel line supplied with the kit? |
For what it's worth: I used Goodyear fuel injection hose (very expensive it turns out), but what I liked about it is it has a high tech core which is supposed to be resistant to auto fuels with the solvents and alcohols. I assume (and hope) it's okay for 100LL also as I will probably have it in the fuel system from time to time on longer cross country flights. The hose seems more rugged and less likely to kink, probably because it's rated for the higher pressures of injected applications. I think the stuff I am using is this: http://www.goodyearbeltsandhose.com/cars/inject.html
By the way I have an Andair mini gascolator, and although the primary (larger)
o-ring is supposedly nitrile (which I thought was really tolerant stuff), it has
shown to be swelling oversize, and I already replaced it. Guessing thanks to
the premium gas here in CT/MA/RI all being 10% ethanol blend.

hi list
i was looking at a few builder sites this morning and
since i am putting on my canopy, i looked at
bill.hoverton.com, and he suggested putting a round
hole over the manual latch to release the canopy.
this seems like a great idea and i plan to use a
rubber grommet to make it look like it was not an
accident. very good idea as you never have a
screwdrive when you need it

I fly a Kitfox III-A ...Its a bit of an odd ball either one of the first
model III or the last model II. Like yourself I have always been
thrilled
at even the sight of the 601 on amphib floats.
The down sides to the configuration as I see it are. If you are going
to
remote places with large rocks forming the shore line beaching the plane
could be a problem. Docking at wharves that have hand rails etc could
be
the same problem. pumping out the floats if the plane is still in the
water
could really be an aquatic (swimming) event as would be loading float
lockers. Carrying anything on the struts would be a non event.
All those items are, to me, primarily convenience features or
inconvenience
features. I think you will find those who are actually flying their
601s on
floats must really like them.... there are enough of them out there.
If I can ever come up with the cash I'll order mine the same day.....
After
all I still have the "Fox" to get in and out of the rough spots.

Brandon,
With the described HDS, no pants, unknown pitch setting etc, the 125
knots might be difficult
to reach, but the objective of getting 130 mph plus is not magic, even
with the humble Subaru.
You need a good set of pants, gearbox fairings, step tube fairings, a
full core spinner, a 17 inch pitch
in a 70 inch prop, a clean aircraft and 100 hp to get there. There's no
magic, just persistent effort
at cleaning up the HDS. The latest finding was that the elevator trim
at the highest speed needs to be
readjusted to allow the lift to move further back and that last
adjustment reduces drag a little bit more.
I believe the HDS might be capable of even more with adjustment of the
prop, trim etc.
In any case, the XLs thin wing will do better with the same effort, etc.
Read my journal section 11, December 27 and the latest GPS airspeed
check and you see that it's
possible if things are in proper adjustment.
Respectfully,

Wade-
Since the bend radii for nearly every material thickness is the
same, the logical inference is that the .125 radius was adopted for
simplicity of fabrication rather than purely structural reasons. Let's
face it, a "One size fits all" bend radius precludes individual stress
calculations. By the FAA recommendations, .125 is way overkill for .016
stock, but nearing the limits for thicker stuff.
Just for kicks, find the thickest material on the plans bent with a
.125 radius and apply the FAA calculations. If I were to draw a simple
to build design, I'd calculate to 2T of the thickest material for a
safety margin and have all the rest of the thicknesses overkill.
That's my RATIONALIZATION, not an expert opinion. I remember that
some of the "What do you do" respondents were aeronautical engineers,
while I deal with plastics. I'd value their thoughts over mine.

Hi Wade,
I am afraid you are dealing a little bit with an apples and oranges
problem.
My take on the standards specification is a minimum radius for the
material. I would interpret this as an absolute minimum. The
designer's specification should take precedence over this standard.
Chris's 1/8" radius should be considered the higher priority. We can
assume he based his structural calculations on this radius rather than
the minimum specified in the FAA circular.
The other side of this coin is the designer certainly included a
considerable margin in all his limits for the design. That means a
small variation from the ideal measurement should not make the design
unsafe. These planes are meant to be built by first time builders, so
the tolerances are generally very loose and the strength margins can be
presumed to be high. I don't recall reading about any tolerance in the
.125 inch bend radius in the builder's instructions, but I am sure this
is not a critical measurement. Still, I would strive to meet this bend
radius in all of my parts.
The bright side of this is once you set up your bending brake or other
equipment to bend parts you will build in the bend radius in the
tooling. Then you can mostly forget about it.
Best regards,
Paul

John,
That's an excellent idea. I've had the canopy come unlatched on 3
occasions. Recently I marked the
lock-line in white across the slot and painted the latch lever white
that aligns with it for a visual check and
that works, but being able to put a finger in and nudge the lever to be
sure sounds even better.
I'm still looking for a fail safe redundant latch-lock, so if anyone has
a good one, post it as it would
certainly be welcome.

Hi Brandon,
I wonder why you feel 125 knots is fast for an HDS. The only other
data points I have from other owners with the Jabiru mounted on an
HDS report over 150 mph cruise.
I am still waiting for some good data on the cruise speeds achieved
with the Jabiru on an XL. Since ZAC reports faster speeds for the XL
than the HDS I am hoping for numbers in the 160 mph range. This is
based on the HDS numbers I have heard and the assumption of a
"Cruise" prop setting.
Perhaps you know something I don't . . .

Doug, I understand. We do have plans to make a kit available at some
point in time. Possibly in 3 years once we have everything set-up for
CNC and press dies, perfect the building sequence and videotape the
whole procedure, design the photo assembly manuals.
However, for now only completely assembled floats and amphibs are
available.

Hello Michael : I have a 601XL and have looked into putting it on floats
. It is true that if you tie up to a dock there could be some clearance
issues . However , a 601XL on amphibs (4 wheel ) negates the problem of
having to buy gas at expensive Seaplane bases . Indeed I keep my 601 at
an airport where I buy my gas . It is my intent to fish and if necessary
beach the plane . Naturally you avoid a rocky shoreline whether or not
it is a low wing or high wing .
I have discussed the issue of low wings verses high wings with
knowledgeable persons who have experience with both . They pointed out
the pros and cons of both and in conclusion it comes down to personal
choice .
I live in Northern Ontario and floats would be nice to have .
It is a tough choice , if you already have a low wing , thats why I will
be talking to Mark and Dave about floats for a 601XL .
One more point , the only people who were negative on low wing floats
had no experience with same , go figure
Best wishes in your choice

Subject: Zenith-List: Floats + 601XL
On this note... When I first started building I saw the picture of a
601 on floats and loved the idea. I think I asked about it at the time
and the responses I got suggested it was not the best of ideas. I know
it is not overly common to put a low wing plane on floats, but I just
can't shake the idea. (I don't even have a seaplane rating, but it is
high on the flying wish list.)
With this thread, I'm just hoping for some people to throw out
ideas/experiences that might be relevant to such an idea.
So...thoughts, ideas, experiences?
Thanks, Michael in NH

Glad to hear about this development. How about the 601XL? Can I
get plans?

Mark:
Do you have a date set for the 601xl amphib floats yet?
or just the 701 for now?
thanks,

Doug, I understand. We do have plans to make a kit available at some
point in time. Possibly in 3 years once we have everything set-up for
CNC and press dies, perfect the building sequence and videotape the
whole procedure, design the photo assembly manuals.
However, for now only completely assembled floats and amphibs are
available.

Mark, now that float production has moved back to
North America, will they be available in any other
form than completely assembled? Specifically, will
either plans or kits be offered?
I'm the stubborn sort that likes to do as much on my
own as possible. It seems like cheating for me to buy
a fully assembled set of floats.

OK, so I'm a few days behind on reading my digests....promise..I'll
catch up!
I'm a morning radio show host, been on the air for 31 years, 19 of them
at KOZY/KMFY Radio in Grand Rapids, Minnesota. I'm also chief
engineer, maintaining 2 air and 2 production studios, as well as 5000
watt directional AM transmitter and 100,000 watt FM transmitter. If
you feel like killing some time, visit the station website :

and follow the links for the Morning Mess and even the Curb Feelers (we
actually have an oldies band made up of station staff!)If you're REALLY
curious, we have podcasts available from nearly all the morning shows,
usually delayed by a day or two.
In my spare time I divy it up between airplane stuff, photography,
record collecting, computers (Mac only spoken here) and I'm a bit of an
ebay-aholic..mostly selling stuff to support my hobbies. Oh..that, and

Larry,
I agree that 130 mph is not magic, and feel that
with some cleanup work, I will get mine there as well.
However, 125 kts seems quite unrealistic for the HDS.
Quick math... 150 mph...
If there is anyone on this list getting 150 mph
in an HDS at 75% cruise, GPS calibrated, please chime
in...

Great question. This thread has been facinating.
I'm a retired (recently) US Army Colonel. I've gone to work (2 kids in college)
as a gov't contractor as a reaserch scientist for a non-profit technology company.
I did one year in the Infantry, and 25 as an Intelligence Officer. Last
assignment was as the G2, Third Army / ARCENT. Got my private in high school
many years ago. Own a 1954 PA-22 Tri-Pacer and am building a 601XL. The kit
is in storage while we build a house (and a shop) in SE Arizona.

Here we are one day later and I deciede to finish the left wing first. Reason:
Less handling of the part during manufacturing. Or lazy, you choose. [Laughing]

I graduated a physics (electro-optics) major some 18 years ago. Didn't find a job
that paid enough to play with lasers and make holograms all day long, so ended
up an electrical engineer (power systems), working for a small consulting
company. Right now I am working around JPL's big dishes that talk to the little
skateboards on Mars and to the space probes!
My expensive hobbies: I am an amateur photographer, private pilot, archer, hiker
and mountain biker. And am working on lifting my second Jeep Cherokee for desert
racing.
After taking the RV builder's class I came to the conclusion that Zenith is a lot
easier and quieter to build in a metropolitan area!!

Larry,
Have to fly the 600 down your way after it is flying and the fly off is
complete - later this spring. What airport is closest to your new house?

| Subject: | Water pump housing Rotax 912S with new "Ring Mount" for CH701 |
Need feedback and help on a slight problem. Recently picked-up from
Zenith factory the newly released FWF package and a Rotax 912S. When
following the instructions on mounting the new Ring Mount to the 912S I
determined the water pump housing hose nipples for the left side of the
engine (from the back) are positioned such that: 1) the mount cannot be
reinstalled due to one of the hose nipples hitting one of the structural
ring mount brackets, and 2) the other left side hose nipple does not
provide for adequate clearance/routing of the connecting hose.
The Heavy Maint manual indicates these hose nipples are held in place
with Loctite 648 and the part needs to be heated to 180F in order to
remove the hose nipples. I am at a loss on the best way to complete
this task. Do I take a small butane torch and heat the area directly
around the hose nipple? Do I place the water pump housing in the oven
and heat to the desired temp? Do I take the housing and put it in
boiling water?
My fear about the torch is somehow warping the housing by the uneven
heating.
Anyone have a suggestion, or have they faced a similar problem? Will
also send a request to Zenith Tech Support to see what they suggest.
Thanks in advance,

I used a heat gun. I think a hair dryer might work if it gets hot enough. It
is going to take more than 180F though. I heated the whole fitting up evenly
and when I felt the adhesive become pliable, I gently moved it into the
needed position using a wooden dowel inside the fitting. let it cool. No
problems.

This thing will not fly until it aaaaaaaaaalllll is done. I have been three
months from finishing for three years. I was thinking I was three weeks from
taxi tests last week. A very experienced new friend of mine told me I was still
three months away. That was after I had a breakthrough weekend thanks to
his help. I hate to admit it but; I think he is right.
Make a plan that works for you. Modify it as is needed. Try to do something
on the project every day. Remember that someday you will fly this thing. It
sure is looking better today; but only because I did something yesterday! I
did not get as much done today as I had planned; but I got a lot done. I have
plans for tomorrow as well. I have passed the point that quiting is not an option.
I WILL FLY THIS THING SOMEDAY.

Just where were those cracks - can you see them without disassembly??
