Jon, mine came with the kit, but I had to buy a position sensor device to
actuate the motor to the flap. Frankly, you really don't need a gauge for the
flap. You just peek out the side and you can see it quicker than you can find it
on the instrument panel. I think we only included the gauge because it was
required to complete the wiring sequence. FWIW, Best regards, Bill

I doubt you would call this clever but a lever can either increase or
decrease the distance moved depending on where you placed the pivot.
On the other hand Ray Allen sells sensors with varying amounts of travel -
.5"(13 mm), .7"(18 mm) and 1.2"(30 mm). But as I recall from my flap motor
even the longest doesn't move far enough.

Hi all listers,
Is there anyone out there that has connected a Ray Allen Flap indicator to a
Zodiac XL ?
I assumed it would be linear, i.e. the distance travelled by the position
detector, and the flap push rod, but alas this is not so, so I need to gear
it in some clever way.
The distance (Linear) travelled by the flap push riod is more than the
position sensor.
Anyone done this, please let me know how, it would be greatly appreciated.
Thnx

Hi List
I have a 601HD 912 with the belly radiator. Since the weather is getting
cold here I was wondering how do you all go about blocking off the air flow
to the radiator to increase your cht temps. I'm used to seeing 190-200 in
the heat of the summer, but now at 45 degrees I'm only getting 173 degrees.
I would like to get the temps back up to at least 190. I have a mesh screen
covering the bottom of the radiator and have slid a piece of cardboard
between the screen and the bottom of the rad. I have about 2/3 of the
radiator covered and I'm still only able to get 173 degrees. Anyone out
there have any simple tricks to increase your cht temps in the winter with
this set up.
Thanks
John

What I have done in the past is to connect the sensor arm to the flap
control arm closer to the centerline of the flap control tube.
In-other-words, if the flap actuator moves, say 4" linear for full travel,
that is at the top of the flap control arm. At the centerline of the flap
control tube it moves 0" linear for full travel. Half way up the flap
control arm is 2" linear, 1/4 of the way up the arm is 1" linear, etc.
Somewhere along that arm the linear distance moved is the same distance as
the sensor travel.
Draw a horizontal line on a piece of paper, then draw another line thru it
at the same angle as full flaps. Now measure along those lines until the
distance between them equals the sensor travel. The distance from where
those lines intersect to the point where you measured to is the distance up
from the flap control tube centerline where you need to attach the sensor.
The sensor requires no measurable force to move it so, I have used a stiff
wire, length as necessary, with bends on each end to pass thru a small hole
drilled in the flap control arm and the hole in the sensor arm. A small
threaded rod with a clevis on each end works very nice too.

--> Zenith-List message posted by: JAPhillipsGA@aol.com
Dear Thread Builder & Flying Friends, the manual on the 3300 says to change
the oil at 25 hours and to use the Shell 100 (50 wt.) or use the Shell 80 (40
wt.) for cold weather. The question is what is cold weather? When I purchased
the engine from Pete he was located in Wisconsin. Does it mean cold weather
in Wisconsin, Australia, or in Middle Georgia? Is there a general margin of
temperature range to determine whether the thinner oil is called for? You all
know there are only two barbed wire fences between Wisconsin and the North Pole
so "cold weather" can really mean something very different depending on where
your at. Hope to hear for someone, Best regards, Bill of Georgia

Hello John Im in Toronto Canada with an 80 hp 912 and we normally around
here use furnace tape and in my situation I have the belly rad and at times
-20-30 I hav eto tape it right off totally ..Useally I have the oil cooler
shut right off first and it rises the temps to around 200 on cruise ....U
know the silver metal tape used around the joints on furnace ductwork...HOPE

I'm not sure about airplanes, but for cars the notion of cold weather
usually talks about the freezing point of water - 32 degrees F or 0 degrees C.
It is probably better to use the thinner oil for mixed temperatures
and keep an eye on it to see if you want to change it early. The
problem with the really thick stuff is it takes quite a while to get
it flowing when it is really cold.

John, I'm up in the Toronto area and temps here are floating around
7C or 45F for those on the old system.
My oil today was at 210F, CHTs were no more than 230F. Any colder and
I'll have to block off the oil rad a bit (I never thought I would say
this since I had high temps for a while during the heat wave in the
summer!). Duct tape or aluminum tape works fine to block it off.
My plane seems to be running better than ever now that I have a
proper exhaust from ZAC. The heavier air density recently has helped
a lot too. I could not be happier!!

my Pelican came with a fiberglass cover that screws in place and completely
covers the rad. you could probably make a manually sliding vent that would
open/cover some holes or slots to make it adjustable. wouldn't take many
flights to figure out how much open or closed to make it at what temps.

Do it the factory way. Wrap duct tape to cover part of the core. Suggest
covering !/4 of the core for a start. That's how Chris was doing it in 1992
when I visited the factory in Canada.

| Subject: | Spring Landing gear for HD/HDS |
--> Zenith-List message posted by: PHFD400@aol.com
Has anyone modified their 601HD/HDS with spring gear? I've seen photos of
an HD that had spring gear. I think his name is Frank Darby and not sure
where he is at. Does anyone have his new email address?
Since our landing incident where the main landing tube weld broke, we used a
crane to lift the airplane and put back on the ramp. Had left wheel welded
back on tube so we could roll and load the plane onto a flat bed truck and
haul home. I will have to replace all gear do to the skidding sideways off the
runway and causing the wheel forks to bend.
So after seeing the photos of the spring gear on the 601HD, I would like to
talk to him, and maybe think about going that route myself. Also have to
replace the the complete tail section which was damaged when wheel flew back and
hit tail. Anyone know of a completed tail section that may be for sale?

*/Jim,
You'd find him on the archives of the matronics page, address was then
fdarby@charter.net
I will send pictures your address because I saved them back to study some time
ago
and what he did is interesting, if not just a little over done. Could reduce the
structural
weight by about half if you were serious about doing this.

Johnathan
I agree with the comments that a position indicator probably is not
needed, however,
I had always planned to have one so I did install a position sensor. I
attached it to
the flap arm with a radio control model clevis and threaded arm. The
position was
determined quantitatively by hooking up the sensor with the LED indicator
and
and finding a position along the arm where zero flaps indicated zero on the
indicator and full flaps
indicated full on the indicator. Once determined, I fabricated a small
bracket to
mount the sensor on.

No one has mentioned using a Tiny Tach for an hour meter. I have had one on my
ultralight for over five years and it works great. It gives your rpm when running
and hours when the engine is shut down, all for about $50.
