--> Zenith-List message posted by: Grant Corriveau <grantc@ca.inter.net>
I changed out my fuel filters yesterday. I was surprised when I cut the old
ones open to find that they had a paper core. (I think this is not allowed
in Canadian regs?? something to do with paper swelling/disolving in the
presence of water?)...
This surprised me because the exact same units I used the first year, had a
plastic screen/core when I cut them open. I guess that's one of the hazards
of using automotive parts - we have no specs nor do we have any warning if
the manufacturer changes the specs...
Can anyone clarify for me this 'rumour' I'm recalling about paper-core gas
filters?
Also, does anyone have a good inline fuel filter that they KNOW the specs
for that uses a 1/8" npt screw-in fitting on the outlet end?
Thanks

I think the greater problem on fuel distribution is the Stratus intake...
before the carbs. Any carbs on that intake will give uneven flow between
front and back cylinders. If that were better engineered, I would be happpy

Grant, I don't have a failed filter story, but in Bengalis' books, he states
several times not to use paper filters but as I recall, his problem is with
water that has collected in the filter freezing and blocking fuel flow.
I bought one from speedway motors because they had the best price. It's a
canister in-line type with a stainless 10 micron screen that can be opened
and cleaned, or replace the screen element if necessary. It is made by
Powerflow, #910-11772 and uses 3/8" NPT fittings but they have models with
other threaded fitting ends. Here's a page with good descriptions
http://www.professional-products.com/fuelfilters.htm
And this very long link is to the product page on Speedwaymotors.com
http://www.speedwaymotors.com/xq/asp/strBase_List.%2791011773%27/hilt.910%2D

Images.yes/sq./cont.1/intPgNo.1/redirect./qx/product.htm
I know everyone has their preferences, but these 10 micron stainless filters
are the best, IMHO.

--> Zenith-List message posted by: DeanMFord@aol.com
Two questions:
regarding 601XL
The on line builders resource indicates that there have been changes made to
drawing 6-W-1. I was assuming that I could find the updated drawing on line,
but was not able to locate it. If someone would assure me that the drawings
are there I will continue looking. Surely I am not expected to purchase new
drawings every time they are changes!
Second,
When running electrical circuits such as for the wing tip lights or lights on
the rudder, is it okay just to run a single conductor to supply the 12 V and
use the airframe as the ground path or is that a bad practice?

Dear List,
I'm a kit 701 builder considering a certified, recently rebuilt Continental
85 with a McCauley metal prop, both of which I already own. The economics
greatly favor it over a new Rotax or Jabiru and propeller, my original
intention.
Any experience with this? For example, could I use the same engine mount as
for a Cessna 140, its current attachment? Would the cowl have to be
modified? What about leaving off the starter? (I'm familiar with hand
propping a Taylorcraft).

Dean,
Complete revision sets have, in the past, run about $50 but changes that
affect
the planes integrity usually come as a notice in the newsletter or by
special letter.
I think putting too much faith in a good ground between surfaces that are
movable is not a good idea. It'll work, but for the extremities like rudder
and wing tip lights, strobes, etc, you'd spend better money and effort by
adding a ground wire that gets each one to the primary ground on the
fuselage.
The fuselage will provide a good return for most items if done correctly.
Good luck,
Larry McFarland - 601HDS

Dean,
Yes the corrections are there, but not corrected drawings
(except 4 pages for canopy). Corrections ("updates") are
text pdf files, and it's up to you to decipher them and
correct your drawings (or $buy new ones).

Generally, yes. Except, for the rudder, I'm planning to
run a ground wire to the fuse, since the current would
otherwise have to go thru the hinge pins.
For general elec info, "aeroelectric.com" is excellent
source (sample drawings, "how-to's", etc). It's also
another forum on Matronics, 'tho it can get pretty
esoteric.

John,
7V4-4 is flush with the rear channel and tucked up against the rib. The top
of the rib is
flush with the rear channel. There is a drawing of this on the next page
7V5. Place a piece
of .016 on top of the channel to make sure you dont drill it too high.
shows it almost level with top of rib but i cannot find anything on the
plans.

In the Installation Manual for the Rotax 912UL, in Paragraph 14) FUEL SYSTEM
is a note, "ATTENTION: Dry type filter elements (paper filter) are not
permitted as they could absorb water and thus reduce flowrate."

Hi Listers--There was some discussion of Lift Reserve Indicators or
Angle of Attack gauges a few months back and it looked interesting to me
since I fly out of a rough turf strip with obstructions on each end. I
bought one of Scott Laughlin's probes when he overproduced a couple and
picked up a Dwyer water pressure gauge on Ebay soonafter.
I finally got a chance to install it today and take a couple of laps
around the field. Man what an education! I made my best landing ever
after flying around the field one time and noted the exact reading of my
stall. I was able to lower my landing speed 5 mph and drop my rollout
by a couple of hundred feet. On take off I read adequate lift readout,
rotated, increased to a good margin and got out much shorter than
usual. I climbed steeper and could see that I had comfortable Lift
Reserve. I think it can be used to fly Vx and Vy with a little
experience. I really reccomend it as a safety investment. If I took it
off tomorrow my flying would be different from now on since I have a
better idea of that the wing is doing at different speeds and angles of
attack.
If Scott will post my install pix, I will send them to his website
sometime soon. Estimated weght is less than 2# and total cost was well
under $75. If you are planning your panel save some prominent space for
one.
If you fly with one you will want one.

Dear Thread Friends, I went through the EAA folks on Friday looking for
insurance for "my never been flown yet" obsession and the least quote I got was
for
$ 2005. per year. Two others were even higher ! Seems about twice too high
to me. Maybe I'm not saying the correct things to the broker. Who has a policy
out there that is more reasonable than $ 167 per month ? Hope to hear
something soon, Best regards, Bill

Since you mention "EAA folks" , I assume you mean Falcon (underwritten by
AIG). AIG is about as fickle as they get. They apparently have 2 major
offices and one will write policies on Corvair powered aircraft and the
other won't. The one that will, is very happy to gouge your eyeballs out.
I just went through the insurance shopping process last month. I was only
able to find 3 underwriters that would insure Corvair powered aircraft; !/2
of AIG, Avemco, and US Specialty. There may be more. I just didn't find
them. Avemco was willing to insure my HD as long as it was not in flight.
AIG left a bad taste in my mouth when they canceled my policy for
installing the Corvair (I had coverage with the wrong half of AIG.) I ended
up with US Specialty, purchased through Skysmith (www.skysmith.com). Scott
Smith (aka Skysmith) is aware of the dilemma I had to go through to get
coverage.
My policy this year cost me $1441. There's a lot that goes into the
calculation, so it's difficult to compare other pilots policies.
