Mike, I wouldn't be surprised if your float created a nose heavy
situation. That sometime happens on float. In anyway, a weight and
balance should be done.
Just my opinion

The first flight of N727EP, a 701 on amphib floats & a Rotax 912S,
occurred 2 days ago at Linden-Prices airport ( 10 miles south of Flint,
MI ). The plane performed & handled great, however I did run out of
"UP" elevator trim. After an hour flight, I returned for an uneventful
landing.
I adjusted the elevator trim tab twice to the point where it is almost
90 degrees to the elevator at full travel and I still run out of "UP"
trim during slower speeds. I am wondering whether an adjustment to the
horizontal stab might help?
Thanks again to everyone that has answered my question & offered
building advice during the last 2 1/2 years.
Happy building, Mike Elrod

If I remember, there are two plastic tubing we can
use. Nylaflow, which is the more common, less
transparent, lower burst pressure, and Nylo Seal that
is a more rigid, transparent and higher burst pressure
(and a more expensive). I guess you have the Nylaflow
tubing.
I'm using NiloSeal and I do not have this problem ....
yet. I noticed however, that the red brake lube tends
to turn yellow after a while. I flushed and replaced
the lube a month ago.. I'll see if it stays red (btw,
the lube that was flushed was more pink than yellow...
it just appeared yellow in the tubing).

I said I was gonna go back to lurking for a year or two after my long
post on how people kill themselves in booths of bad design but somehow
this thing on breathing air keeps popping up.
If you read the MSDS sheet on epoxies and polyurethanes you will
discover that MOST have an ingredient called isocynate ,polyiso,
polyisocynate or something close.
THIS IS NOT SOMETHING YOU WANT TO SCREW WITH.
Several facts on the stuff:
1. Different people get "sensitized" to it at different levels of
exposure, both time and density. Some are very high, some are very low.
2. Serious breathing problems arise when you cross the line. Where's the
line? See #1.
3. Once you are sensitized there is no going back, you are for life.
Kinda like AIDS.
4. Once sensitized, symptoms reoccur upon exposure to as little as 6% (I
THINK I
remember that number correctly, it was VERY low in any case) to what
got you sensitized in the first place.
Remember what I said in an earlier post about nasty stuff that has poor
or no warning signs that it's coming thru the mask? THIS IS THE
STUFF!! It AIN'T like lacquer thinner !!
3M had a cartridge mask that was approved for the above class of
materials, the approval was contingent on you changing the cartridges
EVERYDAY. I used to GIVE the mask away so I'd get the cartridge
business. Don't know if they still sell it or not, imagine the corporate
lawyers went into rigor on that one.
I got sensitized to this stuff when I worked for DeVilbiss Co. a long
time ago (maybe 1970), was down in the hold of a shrimp boat in
Brownsville TX demonstrating spraying urethane foam (it had isocynate).
Was a newbie in the business and thought I was cool wearing my new
orange DeV mask while everyone else wore proper stuff. It took about a
month to come thru the aftermath. Admittedly the concentration was high,
refer to #1.
I had buddies in the industry that had problems in low concentration
wearing full blown fresh air equipment.
35 yrs later I can be in the front office of a body shop where someone
is spraying Imron on a fender on sawhorses outside the booth and I'll
come down with coughing and difficulty breathing. I'm not dreaming this
up folks.
If you have a problem with this stuff I'm gonna tell your wives I told
you so and they will beat the crap out of you while you are coughing and
wheezing on the couch.

John,
I think you are the real expert on the subject. Everything you said is
totally true from my experience. The guys in the house/commercial
painting industry call it lacquer poisoning. I have known people that
have nearly died from exposure to regular cabinet lacquer. After that
they cannot even be near the fumes. I have employees that seem to think
their respirator is a necklace. I used to think it was no big deal when
I was younger. The protection is available. If you don't use it, you can
die. I was really lucky. If I had the same exposure to Isocyanides that
I did to clear lacquer I would be dead. I think I'll go lurk some more
now.

Tracy, I won't comment on your mental status only to say that the mask filter
you are using is probably not enough for safe painting two part epoxy. When I
painted my plane I built a fresh air respirator system for less than $ 50.
that worked well and the photos are posted somewhere in the archives. Do as you
wish, but I recommend you get something better than char coal to save your
lungs. Best regards, Bill of Georgia

Hello Mike,
Congratulation on your first flight. Not much can top this feeling.
"however I did run out of "UP" elevator trim".
Regarding the elevator trim. When you did the Weight and Balance, is the weight
balance forward in the moment area?
If so, where is the battery located?
If it is not in the tail, I would start by moving it there and keep the trim tab
level with the elevator,
and not do anything with the horiz.stab. Better to distribute the weight you have
first.
Just my 2 cents(kronur)

Hi Bill,
I am not familiar with the type of breathing equipment you talk
about. However, it seems to me that the air source is crucial for
such a system. If your paint poisons happen to flow in the direction
of your "Fresh" air source, then the lack of carbon filters might
mean you are still getting exposure to the toxic substances.
I still think the best advice anyone can get when dealing with toxic
chemicals is to read the manufacturer's MSDS and follow the advice given there.
Best regards,
Paul

| Subject: | Re: Epoxy Primer and Personal Safety |
Hi: I am a fairly new lurker here and I see this same conversation
coming up periodically on several aircraft lists so I thought I would
add my 2 cents worth.I began painting in the mid to late 70s for a
comercial trucking fleet where my uncle was the head paint and body man.
It was just anout that time when they began converting from using
acrylic enamel to polyurethane in our shop, and it was just becoming
popular. Imron had been out for a while but we were starting to use
Durethane which is a Ditzler product. We started with our cartridge
masks and the paint manufacturers were RECOMENDING an air fed mask which
consisted of basically a standard mask with a hose connected to it which
led to a standard cartridge filter that the shop air was run thru to
give you a positive pressure mask. My uncle used one of these for a few
years bedore he retired. I continued with a standard mask for probably
15 or so years. by then I had my own shop, still painting comercial
trucks, and still painting mainly Durethane and by then the paint reps
were saying that I needed to be using an airfed respirator. I finally
bought there top of the line system (oilless compressor, hoses, and
mouth/nose mask) and began using it. Great system, but before I had it
paid for they were telling me that I needed to be using a full hood as
the isocynates would absorb thru the soft tissue (your eyes). Before I
even purchased a hood they were telling me that that wasn't good enough,
and that I needed to be using a full suit. It was about that time that
the realization hit me that no matter what I did, if I continued to
paint I was going to die from the effects.I feel that I was fortunate
and at least til now I am not completely brain dead and am continuing
with life but on the other hand each individual has to perform there own
risk analysis decisions and decide what is acceptable for them.just be
informed. Isocyinates are nasty, there is no disputing that.If you spray
them your body will tell you that you have been around them, no matter
how well you protect yourself. There are several new waterbased paints
out which are an option. I haven't used them much and have not been
impressed with the results.As an aside, I remember watching my uncle on
a regular basis take a rag soaked with lacquer thinner and use it to
wipe the paint out of his eyebrows after painting. Although now rather
frail, he is still out and about and in his 90s. I still paint my own
projects, Still paint with durethane, and it lasts and lasts for a very
long time. Off my soapbox now. Dan Hill

Mike,
The trailing edge on the elevator of my 701 was bent up as per the
plans. This caused a nose down in cruise. After bending the trailing
edge to be even with the top elevator skin and adding a larger trim
surface, I can trim OK. ZAC had to bend the trailing edge of their 701
elevator down also.

I adjusted the elevator trim tab twice to the point where it is almost

| Subject: | Re: 701 First Flight |
Mike,
I also bent my trailing edge of the elevator. Roger from the ZAC factory
told me about it, he said that it was originally bent up because the 701 was
originally designed for the Rotax 583 engine and that would help keep the nose
down. I found that before bending it, my trim tab had to be 1/2 way down from
neutral to fly level. Now it stays in the middle and flys level. I still use
just about full trim when landing and it seems to work out OK. I used a 2x4
with a slot cut in it to straighten out the aft end of the elevator, it did not
hurt the paint at all. I would think that the factory would make the
trailing edge straight as I don't think too many people use the 583. Congratulations
on your first flight.

Mike,
The trailing edge on the elevator of my 701 was bent up as per the plans.
This caused a nose down in cruise. After bending the trailing edge to be even
with the top elevator skin and adding a larger trim surface, I can trim OK.
ZAC had to bend the trailing edge of their 701 elevator down also.

Subject: Zenith-List: 701 First Flight
The first flight of N727EP, a 701 on amphib floats & a Rotax 912S, occurred
2 days ago at Linden-Prices airport ( 10 miles south of Flint, MI ). The
plane performed & handled great, however I did run out of "UP" elevator trim.
After an hour flight, I returned for an uneventful landing.
I adjusted the elevator trim tab twice to the point where it is almost 90
degrees to the elevator at full travel and I still run out of "UP" trim during
slower speeds. I am wondering whether an adjustment to the horizontal stab
might help?
Thanks again to everyone that has answered my question & offered building
advice during the last 2 1/2 years.
