Larry,
You're right about shrinkage. The stuff needs to be
very dry to sand it and avoid seeing it. Mine's still solid
but an epoxy mix with fillers might be better, especially if
the dinks were deeper. Getting a filler that sands evenly
and more readily than aluminum is the reason I used the
lacquer, but an epoxy has more grip in any case.

The plans call for an aluminum fairing under the fuselage that covers the step
cross bar and two small aluminum fairings that cover the step legs. Welding steel
fairings to the step treads might reduce the drag a slight bit more. As for
the area around the landing gear, in the air, the horizontal part of the gear
spring should fit flush with the bottom of the fuselage and not need to be faired.
I suppose the attachment brackets could be faired in, it depends on how
much additional work you are willing to do to gain a small amount of drag reduction.

I saw a realy neat tailight somewhere on a web site
not to long ago.It was pressed or formed into the
trailing edge of the rudder.It was formed out of sheet
aluminum and I belive it was a shaped block of wood
that was used as the form. The wood had a bulge in it
that formed the bubble that the light sat in.If anyone
knows where it is posted please let me know.If not
thanks anyway.

I noticed on the recently completed XL that showed up at Zenith Open Hanger
Day (I don't remember the builders name) that it had a fairing over the
support going down to the step and on the support underneath connecting the
steps. I asked about it and he said it came with the kit. I haven't
checked to see if it was included in my kit. A fairing where the gear meets
the fuse may also help cut drag. I am considering not installing the step
and keeping a small plastic stepstool in the plane for my short legged
friends. (the question is how they will get to it to use it).

No. I do know from experience that the factory presets the flat pitch stop
to a nominal match to your engine HP. The first one was set for a 912S and I
couldn't even get 5500 rpm WOT above 2000 ft. This was bought thru a dealer.
When I had severe vibration when the bearing in the hub went bad I just
checked the slop in pitch, 2 degrees,in one blade with the prop on the
plane. I have a simple jig that uses a keyring laser pointer epoxied on to
give very accurate and repeatable measurements but it is not calibrated to
an actual standard. I built it to set my GSC 3 blade prop. See Zenair News
#112. Since there are a lot of curved surfaces involved, I'd have to have
the factory calibrate it for me. This would be a total waste of time as each
plane and pilot will have a specific optimal setting to be found by trial
and error. Make the plank close to paralell with the back of the prop. Shine
the laser on the wall for relative measurements.

Firget it it ain't gonna work in the real world.....fit the step!
The (HDS at least) is such a draggy airplane I bet you coulnd't measure
difference in drag with vs without.

--> Zenith-List message posted by: xl <xl@prosody.org>
Hello again all,
I've posted a set of photos at: http://www.cleanh2o.com/633z/
There are large (~700k) and small photos (~70k for faster downloading) of:
- N633Z at the EAA tent at the Arlington Airshow!
- the stock muffler
(I did suspend the tailpipes on the second one, it still failed in 10 hours)
- the busted stock muffler
- the straight pipes that I made it home on (after my CO detector saved me)
- the homemade 'swedish' mufflers that I installed last week
(they weigh about 3 pounds a piece and are nice and quiet,
the intercom works better without as much background roar,
and the plane still seems to fly as fast)
- photos of the skin polishing - in progress
- and as a bonus some building location (yes, I'm in one of them)
and a moving photo
Enjoy!
Joe E
N633Z @ BFI

P.S. I planned to make a go of flying to the Zenith Open Hanger Day
but I too was grounded by the weather. Maybe next year!

--> Zenith-List message posted by: "Norm Turner" <normsflighttraining@bigpond.com>
Hi to all on the list, Today is the day I have been waiting for a long time / 14
weeks!! for it to be built and shipped to me in Darwin from Airmaster in New
Zealand . With lots of luck I will receive my new Airmaster constant speed prop
with full feather ability, all electric controlled. AP332 with the AC200 smart
pitch controller. I only know of one other CH601 HDS with this set up in
Australia . When I get it installed and tested I will post the results. This may
take some time as I will be doing most of the testing during my trip south
on 26th September and will be out of town and away from computers!!. I will then
have a Bolly Optima 3 ground adjustable prop for sale. Cheers Norm Turner
601 HDS 350 hrs 912ul

I am sure this has been brought up before, but...
As I am planning to start my (4th) Zodiac XL, I am considering building
it from plans rather that kit form. I don't know much about metal
working other than small amounts that I have learned over the years from
reading, but I do believe I can pull it off.
With that said, I know there are a lot of people out there building
Zodiac's from plans. Is there any method in place to loan or rent each
other form blocks, etc. to make the parts? Seems we could all save a lot
of time and money if those of us that are, or are planning to, building
from scratch implemented the divide and conquer method, whereas we work
as a team to create the forms (or even create the parts for each other)
and then share with others.
Just a pipe dream, or should we be content re-inventing the wheel we
know already exists in somebody's scrap pile :-)
