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 ________________________________ Message 2 _____________________________________ Time: 09:41:30 AM PST US From: "Craig Payne" Subject: RE: Zenith-List: Flap position indicator T_TM2_M_HEADER_IN_MSG autolearn=disabled version=3.0.3 --> Zenith-List message posted by: "Craig Payne" 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. -- Craig -----Original Message----- From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of Jonathan Starke Subject: Zenith-List: Flap position indicator --> Zenith-List message posted by: "Jonathan Starke" --> 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 Jonathan Starke ________________________________ Message 3 _____________________________________ Time: 10:11:38 AM PST US From: "john H" Subject: Zenith-List: winter flying and coolant temps --> Zenith-List message posted by: "john H" 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 ________________________________ Message 4 _____________________________________ Time: 10:28:01 AM PST US From: "Dan Ribb" Subject: Re: Zenith-List: Flap position indicator --> Zenith-List message posted by: "Dan Ribb" 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.

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.

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. do not archive Paul XL wings At 11:04 AM 10/28/2005, you wrote: >--> 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.

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!! Trev Page C-IDUS 601HD R912 On Oct 28, 2005, at 1:10 PM, john H wrote: > --> Zenith-List message posted by: "john H" > > Hi List > I have a 601HD 912 with the belly radiator.

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.

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?

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.
