yep I've gone with an electric flap
got a flap actuator out of a old Jaguar fighter very light and powerful
150kg force
weights less than the crome molly flap arm it is replacing
now need to get some form of indication of setting
I liked the idea of the potentiometer mentioned on the list

I don't have a really good answer to this as I'm
fairly new to engine mechanics... but I remember GRT
telling me that if I can't use the sender attached to
the sparkplug, they would exchange them with another
one that can be attached to a head stud.
They ended up fitting very well on the spark plug and
I'm sure that GRT will exchange them at no cost for
you if you want to install them there.
There was a thread on Airsoob a while ago where
several people claimed there was no reason to use CHT
sensors. One made mention that CHT sensor could show
a problem with coolant (if you lose coolant, it would
take more time for coolant temp to go high than it
would for CHT to go high). I did not reflect much on
the validity of this... I just installed the sensors I
got.

I did'nt look at that at all. Being Canadian, I'm not
much affected by that Sport Pilot thing. In Canada,
we have a "Recreational Pilot" category which I think
ressembles what that Sport Pilot would be. A
Recreational Pilot can fly with a passenger, but
cannot have any annotation to his license. I think
most people in Canada pursue the private pilot license
anyway unless they go for an Ultralight license (some
Canadians could comment on that?).

As he has said he would for several years now, Chris Heintz announced at
the Zenair builder's dinner that he would be taking a smaller role in the
business side of Zenith. He indicated that, for instance, he would only
attend a day or so of next year's AirVenture just to talk to friends and
builders. He pointed out that "his boys" were well positioned to carry on
the business without him. He seemed to indicate that his designing days may
continue, however he didn't elaborate on that. There was a second speaker,
George, that discussed the heartening story of the 701 built by junior high
school students. They have just received a donation of an engine so the
students' project will fly. Chris indicated that there are somewhere around
2000
flying Zeniths around the world in about 50 different countries. At the
dinner I had a great opportunity to meet
other builders including Pat Stafford, Ed Kramer and his wife Jan, Mark
Townsend, David Barth, and Rick Herndon. My wife had a long discussion
with Matthew Heintz. The sound system at Robbins was very poor.
As others have noted, Zenith homebuilts were very hard to find on the
field. I found none. This was strange after so many were at Sun-n-Fun.
At the Zenith display, there was an XL fuselage demonstrating the
conventional gear (tail dragger) and dual stick options. There was also a
640
on display. No mention of a CH152, the Gemini, or the like.

--> Zenith-List message posted by: "H. Robert Schoenberger" <HRS4@prodigy.net>
List . . . I'm at the point of installing my first wing tank in the right wing
(701). When I try to screw the finger filter fitting into the lower corner of
the tank, I'm meeting a lot of resistance. I finally turned it in about 2/3rds
before the force became too great to the point where II was worried about
breaking a weld. I turned it out (it came out easily) and examined the threads
under a magnifier. There is no evidence of cross-stripping. I thought maybe
in the welding of this femail fitting into the corner of the tank, the fitting
deformed ever so slightly. Would it be okay to use some sort of lubrication
oil or will this screw up the sealant when the fitting is permanently set?
Did any of you have this problem?
This all happened when I tried to do a surgical glove air test for weld leaks.
The glove was installed over the filler inlet and sealed with a tight rubber
band. I thought this test would be a simple process, but the little red caps
in the outlet holes proved not to be tight. It was then I installed the above
fitting. I don't think I have any leaks except around the outlet holes and
I assume this will be fixed with some sort of sealant at final assembly.
Would it be all right to install teflon tape on the threads of the outlet fittings
just to seal them for testing and then remove the tape? Thanks for your help.

List . . . it was one of those frustrating days when everything I seemed to touch
turned to baloney. First the fuel tank testing procedure did not go well (the
fittings did not fit well and leaked (see this afternoon's email call for
help). Next I decided to mount the fuel sender in the fuel tank. It recommended
that the sender be tested in conjuction with the actual fuel gage which I
found in a small cardboard box. There were no instructions for wiring the gage
in the box, the sender float unit did not have any instructions other than
how to mount the sender in the tanks and a recommendation to test it with the
fuel gage, the 701 manual references a visual fuel line which I assume must have
been for the old header tank, and I don't find any wiring diagrams in the plans.
What am I missing and where do I find it?
I checked the Tony Bingulas (?sp) book I have and there wasn't much specific to
the above. I know nothing about electricity and wiring. Where can I find this
type of information? Is there a good reference book available? Thanks for
your help. Frustrated Hap Schoenberger 701 - working on right wing.

H.R.S.,
I originally welded the threaded fitting to a piece of angle to serve as
corner and draw heat in final welding, and avoid distortion, but like you,
I also had the difficulty of tightening finger strainers in my tanks and
again, in my header tank, the elbow fittings.
This is a 601hds, but the problem's the same. I had to run a NPT tap
through to be sure there weren't any loose parts in there and use AntiSeize
compound to secure the fittings to avoid galling the threads. Tightening
the threads to something just short of the low-side of the torques given in
the Standard Aircraft Handbook with AntiSeize should be adequate.

Hap,
The Bengilis book Firewall Forward has a good bit on hooking up specific
items, but the best electrical references that can be had for the
electrically deficient we share is a manual called The AeroElectric
Connection by Bob Nuckolls, obtained at a web site of the same name. A
growing archive of electrical info is also available at the Aeroelectric
Connection site within this Matronics List.

If that's the same gauge that came with the wing kit I bought, there's 3
posts on the back of the gauge. The (S) post gets wired to the fuel
level sender, the (+) post goes to 12 volts poitive, and the (-) post
goes to 12 volts negative (ground).

I saw 2 601 and at 2 or 3 701s. It was a good time and I was glad to
meet other builders (there were quite a few).
I talked with Chris about the Gemini - it is being put back together now
(I believe with new engines).

Check my site http://members.thegateway.net/cfd and look under wing tanks
and also fuel system. When I get back to the hanger I will make a copy of
my sender wiring diagram and send it to you directly.

Hey All
Today is the day that I considered my Zodiac to be finished. I had my final
EAA inspection last Friday and today I finished up what the Tech Advisor ask
me to.
I got the weight and balance done this weekend. It weighs in at 690 lbs.
Empty CG is at 246.8 mm using the leading edge of the wing for a datum line.
I can't get to the forward limit unless I have a full load of fuel and get
out. That ain't happening. To exceed the rearward CG, it would take over 80
lbs. in the rear, no gas, and my wife and I in the plane.
I took the plane out on the runway this evening. This is not the first time
I have done this, but it was the first time with everything in place. In the
past, I was very careful to not go very fast, but today I was a bit more
daring. I went through runup and everything, just like I was going to fly.
Then I throttled up to about 3000 and released the brakes. I didn't actually
time it, but seemed like it took maybe 3 seconds and I was looking at 30
mph. This thing accelerates real fast and I didn't even use full throttle. I
have this feeling that the takeoff run is going to be real short.
This week, I'll try to get all the paperwork in order and schedule the
Airworthiness Inspection. I'm excited!
