Hello Craig,
I built and fly a CH640 (mine is the red/white one on the Zenair update page).
They used to have a rudder build class at AMD in Eastman, GA, but I don't know
if that is still available. Support for the 640 comes mainly from Zenair directly,
or AMD. If you have any questions, feel free to contact me directly at stephen.adams@hcahealthcare.com.

I have looked at the information on the Zenith website, but then when I started
looking for actual engines to purchase I started coming across a bunch of different
models of each of these. The Lycoming 0-235 engines generally have some
more model numbers after the 0-235 that seem to indicate different horsepowers
and stuff like that. And I don't know which of these would be suitable for
my needs.
Don
I assume you've looked at the specs on the Zenith website
On the certified side the Cont 0-200 and Lyc 235 are the most common.
There is a link to a number of other engine choices at

The skin radius was to small using the 1.75 stop blocks and I will try again tonight. This time I will make several test strips and work it through the whole process. Also I will start with 58mm blocks, just like it says on http://ch601.org/resources/Nose%20Skin/bending_a_nose_skin.htm More later.

They make several different versions starting at under $100. I got the

The 0-200 in my 150 gets carb ice if I even look at it wrong, but then again
Seattle tends to have moist air in the right temperature ranges most of the
year.
Once in a rented 172, somewhere south of Denali/McKinley I got some bad carb
ice, so bad that there was some sputtering when I applied heat. It had only
been five minutes since I had last checked for carb ice. Luckily it cleared
up and all was OK.
Nothing will convince you more that carb heat needs to be checked often even
in cruise than then impending reality of an engine failure somewhere in
Alaska during the winter.

forwarding this on and have no more information than what is below.

...the engine has just under 100 hrs on it. It was used only as a test cell
engine. In the cell it was used to see if we could get 80hp at 80,000 ft. We
did it with three turbos and electronic ignition and fuel injection. We saw
65hp at 90,000. After the test it was left in the cell for a good six months
and never touched again till we put it in storage in a transportainer. Now
it is in my hangar. It is as we took it out of the cell, without the exhaust
and intake system installed. If anyone wants it they can have the removed
systems. Along with the engine. It will come with a very expensive oil pump
and a bunch of other hardware.
The engine would make a very good short block.

If you have a carb you can get carb ice. You may have to be a member but here is
an excellent article on the subject with a great chart showing how ice even
if the ambient temp is over 100.
http://flighttraining.aopa.org/members/student_pilot/presolo/articles/58.cfm
[quote="arno7452(at)bellsouth.net"]Dear Listers,
I am installing 912 ULS on a CH 701. Due to its cost and perhaps debatable utility,
I have been advised to leave it off. I sure would like to hear some
comments from the list as to whether this is a good approach.
I am taking lessons in an Evektor Sportstar with 912S engine. So far, we have
never used the carb heat. I am flying in Goldsboro, NC. That is about 60
miles east of Raleigh. As I recall flying the Continental O-200, we used carb
heat anytime under 2K rpm.
The POH on the Sportstar only requires carb heat if you suspect icing. i.e.
engine starting to lose power and run rough.

Hi Bob,
I decided to call Lockwood and ask about the Carb Heat Kit. The lady was very nice. She said they did sell the kit. She directed me to the manufacturer's web site http://www.skydrive.co.uk/sd_sa_ch.asp . She said this was in the UK, so I'm not sure what state that is [Rolling Eyes] .
Lockwood sells two version, with and without a gauge, priced $295 and $325 respectively.
I had a Carburetor temperature gauge on my old Cessna and it was very
accurate. I included it in my instrument scan while flying.
So, if anyone is interested in buying a carb heat kit from Lockwood, then this
is the item. It is also on page 154 of their 2006-2007 Catalog.

Looks like there are at least three approaches to carb heat for the 912S.
Heated air, carb heat air box system.
Hot coolant flow, see in Lockwood catalogue.
Electric heat, again in Lockwood catalogue.
Any experience or comments please.

I have had the Drill Doctor XP2 for about 2 years. I have not had any
problems with it at all.
It does have a replaceable grinding wheel, but can hardly see any wear on
the wheel and have done a lot of sharpening of #30 and #40 drills. It
really does a great job, nicely centered grind on the flutes every time. I
also do a side cut on the flutes, it does that as a second step in the
sharpening process. Makes the drills go thru aluminum just like it was not
even there. I do use a high speed small air motor to drive the drills.
It comes with a "training" DVD that takes you through the entire process and
even shows you how to service your tool.
They have them at Home Depot and sometimes they have a $20.00 rebate slip
right along with them. Got mine that way!
Highly recommended!

I was extremely sceptical about the Drill Doctor. A small grinder in a
plastic housing. Well someone at work bought one to sharpen bits instead
of replacing them. I took it home and put it to work one day just to see
what kind of foolish gimmick it was. I now have a huge quantity of
correctly sharpened bits. I hate to admit it because I still think it's
a little gimmicky, but it works. It's slightly harder to get the small
bits aligned properly, but I was trying the cheapest model. Maybe the
others are better at this small nit.

I know this has come up for some of the other ZAC planes, but when I
took the bottom fuselage skin for my 801 out of the box I discovered
that it is .016. I just assumed it would be .025. It seems like it
should be heavier given the kind of use the plane was designed for. Any
thoughts, anyone?

I'd take the .016 piece and lay it over a piece of .020 (not .025) and
use it for a template. .016 is noisy until you've got
lots of paint on it.

| Subject: | Decision on Carb Heat for Rotax 912 ULS!!!!!! |
Listers,
Many thanks for all the good comments regarding Carb Heat. I have
discussed the issue with Lockwood and Zenith in Mexico. Here is summary
of discussion with Zenith: The cowling for the CH701 maintains a
relatively warm environment. If the Rotax airbox is not installed, NO
carb heat is required. So, my CH701 will be using the new cowling and
there will be no airbox. So, I will not install carb heat.
These comments are based on discussion with Sebastian Heintz at Zenith
today 2/6/2007. Sebastian indicates there are hundreds of Rotax 912s
that do not have carb heat. They are doing nicely. He also estimates
about 3 hp is lost by not using the airbox to draw in cold air.
To the best of my knowledge, I received no comments from Zenith owners
flying behind the 912 without carb heat.
The carb heat upgrade can be retrofitted at a later date. It is a
collar that fits on the carb and circulates cooling fluid. Fairly
simple install I'm told.
Again, many thanks for your interest and comments.

I was planning on using .025 because that's what most of the rest is. I'm
not disputing your suggestion but, why .020 instead of .025? Do you have any
idea why the thinner material on the belly where it seems like it would need
the protection?
Thanks,

| Subject: | Bing carb on Jab3300 |
I found this on the Yahoo Jab Engine site any one had similar problems as the fuel
pump that was sent with my XL kit was the 40105
Chris..
frm the site.....
first engine start went well except that i had fuel leaks from the bing
carb. i have a facet 40105 electric fuel pump that really overpowered
the needle valve controlled by the floats. this is the pump i understand
is used by many jab owners. after a short engine run without the elec.
pump i shut the engine down as the manual pump was also causing fuel to
leak. leaks were coming out the vent for the fuel bowl.
i spoke to bing and was told that these needle assemblies come with
several spring stiffnesses. i had the weakest spring assembly. bing is
sending me the medium stiffness spring. bing said the stiffest spring is
too stiff and not offered any more. bing said a pulolator pressure
regulator is commonly installed in the fuel line. bing also said they
get a lot of calls for the same problem from a lot of 40105 owners.
maybe i should be looking at a facet pump of around 2-2.5 lbs. i believe
they are made and would be more desireable because these lower pressured
pumps have no check valves. thus no possible valve to stick.
does anyone have anything to add to this or offer any fuel pressure
info?
and also, jim of pacific jabiru was helpful and patient with my phone
calls as all of this was going on during the first start attempt.
