I'll have to take an "engage brain before opening mouth" on this one; I was
thinking in terms of auto radiators...
Re: the Installation manual, my copy is dated 09/01/1998, an on Page 11-3 it
shows water flowing from the Water Pump to the TOP of the Radiator, while on
Page 11-4 it shows water flowing from the Water Pump to the BOTTOM of the
Radiator.
So, in this instance, it apparently makes no difference.
Mea culpa...

Bill
Rather than waiting for someone else to explain these hydraulics and physics
principles that apply to this situation, how about you go ahead and
enlighten
us. I went and got my manual out of the box of the brand new 912S that I
just
had shipped to me 3 weeks ago and the diagram actually shows the hose going
from
the water pump to the top of the radiator (as I had it installed on my
912UL). I
have also seen the hoses ran the other way with no adverse affects. I was in
error on one assumption however, instead of the coolant going from the water
pump to the radiator, it actually goes the other direction and is pumped
directly into the heads on the engine. BTW, my local A&P deals primarily
with
certificated engines such as Continental & Lycoming, so if you have
knowledge
concerning Rotax engines and their cooling systems that is not included in
the
manuals, I am sure that I am not the only one that would be interested in
hearing it.

All Rotax engines will chug along with a complete loss of coolant from the
system. You will most likely have some cylinder head warpage, but the
engine wont seize. Not the same with oil!
-----Original Message-----
I will add one little caveat to my previous post, I can see that if for some
reason you
have been losing coolant, pulling the coolant from the bottom of the
radiator might allow
you to go a little further before the engine seizes up.

As I am about to fly the demo 601XL and will probably order the kit soon
thereafter, what is the consensus of the list on how many extra rivets (and
what sizes) I should order with the kit? I figure the need for more rivets
is inevitable (I've built an ultralight trainer so I believe that extra will
be needed) and I would rather pay for them up front and not have to wait for
them later plus pay extra shipping. What do the completed builders think on
this question?

--> Zenith-List message posted by: Tebenkof@aol.com
Dear experts and others with opinions,
I am putting in the old Grand Rapids EIS4000 with my 912S. I did not order
the fuel flow/totalizer feature, but am planning to do so before finishing
the installation. The company wants $375 to add the fuel monitor system, which
seems to be nothing more than the additon of a FloScan 201B fuel flow
monitor. Said monitor is available several places on the web for around $125.
I have not asked the Grand Rapids folks yet, as it is weekend. Am I
missing something?

Hi Ed,
I don't think you should worry about rivets supplied with ZAC
kits. I have been building from sub-kits and always have rivets left
over. In one case, I ran out of A5 rivets with one hole left to
fill, so I requested information on getting some more. They just
sent me 50 with no charge and no paper work.
I have not been so lucky with solid rivets in the kits. The little
ones used to mount nut plates are so small they want to jump off the
bench and hide in some small cranny in my shop. In this case they
counted them very carefully and didn't give me any extras at all. I
decided to order a bunch of extra nut plates and rivets along with
the matching screws from Aircraft Spruce and Specialty. This not only
allows me to stop worrying about losing the little tiny rivets, but
gives me spares to make extra inspection ports for stuff not included
in the kit (like my Lift Reserve Indicator).
Fortunately the standard AN or MS parts are easy to order and not
very expensive.
Good luck,
Paul

--> Zenith-List message posted by: "kevinbonds" <kevinbonds@comcast.net>
I need a recommendation on a good dimpling and riveting tool. I like the
idea of this particular tool
http://www.aircraftspruce.com/catalog/topages/handrivdimptool.php but, don't
know much about it. It is described as a "hand" tool but doesn't describe
how to use. Does anyone on this list have it? Does anyone know if it is a
good tool for dimpling skins? How does it work? I need to install those
nutplates and 3/32 flush rivets for the Fuse access door. Also would it work
for the solid rivets for the spars? I have yet to make those. How about
other suggestions? I have given some though to flush riveting certain
sections of my plane like wings and fuse. Also with the above tool, do I
need a rivet gun or can I use a hammer to set the rivets?

Hi Kevin,
Have a look at the DRDT-2
I bought this dimpling tool to do the skins on my XL kit, it works
beautifully and there is no guessing about how hard the hammer blow
needs to be, you just pull the handle to compress the sheet metal
between the dies. It has an adjustable stop so you can't over do the
dimpling by exerting too much pressure and this guarantees that you get
nice uniform dimples.
