Hi Paul:
If you are talking about the 601XL, here's a photo of how mine fit:
http://www.cooknwithgas.com/5_30_04_Wingholes.JPG
The top of the sender did not touch the skin, but I put a plate there anyway
for future access if I have trouble with the sender. It's the float type
sender. I did grind the center bolt in the center to make sure it was as
low as possible.
You can see more photos of the installation on the "wings" page of my
website.
Hope this helps.

Hi Paul,
I put a UMA capacitive fuel sender on my header tank in the 601HDS and
mounted it on the side, close to the top of the tank. If you tell UMA what
your requirements are, they will give you a pickup tube to accomodate your
needs. Mine has a 4 inch portion that can be bent so as to position the
rest of the tube to point into the top of the fuel tank. It's a bit like an
upside down "J" bend that allows the sensor to read fuel level that is
higher than the sensor. I found UMA to be very helpful on the phone.
It took a bit of care to cut the hole in the side of the tank and make my
gasket to seal the hole, then fish the nuts thru the filler cap to seal the
sender but it now works fine and calibrated just fine. Write me off list if
I have confused you too much, but it's possible to do the side installation
and causes no clearance problems.

Actually, there is a reason for the apparent dearth of clecos------- Just as it
has been noted that coat hangers left undisturbed in a dark closet will mate
and multiply, and their progeny will mate and multiply, etc., clecos are known
to be intensely hostile to each other, no matter what their size (breed). What
happens is that, when left undisturbed in a dark shop overnight, they attack
each other, killing each other off at sometimes hideous rates. Being also intelligent
creatures, they hide the bodies of their erstwhile compatriots, generally
where they will never be found. That is why you never have as many clecos
as you had...........

The DAR inspected my aircraft today and issued the airworthy
certificate. I decided to go ahead with the test flight today since it
was a perfect day for it. She flew GREAT except for a very heavy left
wing. I think I know what I did wrong so I am going to check the wings
to see if I have the rear of the left wing lower than the right wing. I
think it is off by about 3 degrees. If this does not do the trick then
I guess I will have to add a trim tab to the right aileron.

That gives me an idea. With only a few small holes in any sort of clothing,
you could cleco it to a wall when wet, eliminating the need for a clothes
line and possibly an iron.
Or a special tie-rack that uses clecos to keep the ties in place. A small
hole in the bottom of a tie would not be noticed and it would never fall of
on it's own.

Hi Roger,
As has been pointed out already, I do have a CAM100. The builder resource
page contains a short summary of my experience with the engine so far. Now
that I've gotten most of the ancilliary systems 'debugged' - I'm hoping for
some trouble free flying.
http://www.zenithair.com/bldrlist/pm.cgi?login=Grant&action=display&
If you care for more detailed info or have any other questions, email me and
I'll send you a short 'essay' regarding my CAM100 experiences so far.
As I understand it, the company is currently for sale as Bob Masters and his
partner wish to retire. Overall this is an excellent product line (CAM100;
CAM125; the dual channel electronic ignition system; the PSRUs...) I hope
someone buys the company and continues offering this engine as an
alternative automotive conversion -- and of course I would sure appreciate
ongoing factory support! ;-)

Andrew,
My condolences to you and the families involved.
As fellow pilots and builders we cannot put into words the sorrow we feel
when we hear news like this. I can only imagine what you are going through
right now. I lost my flying partner in a crash four years ago and that was
the worst day of my life.
My advice is to take some time away from aviation. Then try to understand
what happened. If you did everything right try not to blame yourself. You
weren't at the controls. I'm not speculating here but most accidents are a
result of the pilot, not the plane. Discussing the incident with fellow
aviators is the best therapy there is and we are always here if you want to
talk about it.

If the rear of the left wing is lower it would make the right wing heavy not
the left.

--> Zenith-List message posted by: Brandon Tucker <btucke73@yahoo.com>
Gents,
I recieved a quote from Grove landing gear and am
looking into a group purchase. The quote for a 601
HD/HDS gear is $1771.63 for gear, gun drilled brake
lines ($100), axles, 5" wheels and brakes($549),
spacers, nuts, bolts, and the kitchen sink. For a
purchase of 3 or more, they will take off 15%. That
brings us down to $1505. I am not in a hurry to buy
at this point, so what I am looking for now is who
MIGHT be interested in a group purchase of this gear
sometime in the next 6 months or so. I may already
have 2. Please respond to btucke73@yahoo.com so
that I can conduct the business end of it off list. I
live 45 minutes from the Grove factory, so I might be
able to save on shipping as well. If any of the 701
or XL guys want in, I can look into that too, but you
XL builders will have to modify your lower longeron
gear attachment brackets to fit the smaller gear. The
size of the Grove gear is 7/8" by 4 1/2". The size of
the 6061 XL gear is 3/4" by 7 3/4." According to the
XL plans, the gear weighs 43 lbs, and the Grove gear
weighs 27.8 lbs. (15.2 lb difference!)
I will e-mail ZAC for a price on the XL gear,
just for comparison purposes. I also have an e-mail
out to CAW to find out the exact weight and price of
their composite gear, for those interested in that
information. I will keep the list informed of my
progress.
Respectfully,
Brandon Tucker

--> Zenith-List message posted by: "royt.or@netzero.com" <royt.or@netzero.com>
Leo,
www.evanscooling.com has products to help remove water from cooling systems.
If you are not already registered to receive updates from Rotax, you may want to subscribe at http://www.rotax-owner.com/reg.htm There was a clarification sent regarding Evans NPG+ coolant:
When determining the type of engine coolant to be used (standard glycol / water
mixture or Evans waterless coolant), all owners and operators of Rotax 912 /
914 series aircraft engines should carefully review the appropriate sections of
the revised Installation manuals.
The latest revisions of the Installation manuals set out new LOWER maximum allowable
CHT temperature limits for engines using conventional water / glycol coolant.
When considering the use of conventional water / glycol coolant, owners
and operators, as well as aircraft designers and manufacturers must insure that
the new LOWER maximum CHT limits will not be exceeded.
In installations where engine cylinder head temperatures may exceed the new lower
limits set out for conventional coolants, Evans waterless coolant must be used.
Once again use of conventional water / glycol coolant is only recommended if engine
cylinder head temperatures will never exceed the new lower values set out
in the latest revisions of the engine installation manuals. In all other cases
Evans waterless coolant MUST be used.
I have not determined if my custom instatllation with a Rotax radiator in the cowl
should be changed to the Evans coolant.

Incorrect, if the rear of the right wing is lower then the right wing will
be lighter and the left wing will be heavy.
Think of it as what happens if you lower your right aileron, the right wing
will go up... same thing if the entire wing is lower in the rear.
Anyways, I have corrected the right wing mounting error and now the aircraft
can be flown hands free in perfect level flight! WOOHOO!

| Subject: | Flying Qualities of William Wynne's 601XL/Corvair |
--> Zenith-List message posted by: "Phil Maxson" <pmaxpmax@hotmail.com>
I was fortunate enough to be able to visit William Wynne, Grace and the gang
at Williams hangar on Sunday. Once more, I am impressed with these people.
They go out of their way to help the average builder, like me, to get
planes in the air. In addition, they are nice people to sit around and chew
the fat with I wouldnt cross the room to hear most people's opinion, but
in this case I drove across the state of Florida to spend a few hours with
them. And it was time well spent.
The highlight of the day was when Gus took me for a flight in the
XL/Corvair. What a plane! I am pleased with the match between the engine
and the airframe. Gus allowed the tail wheel to stay on the ground and let
the plane fly off when it was ready. The result was that the plane flew off
in the three point attitude and climbed at better than 700 fpm, at gross
weight. The plane is light on the controls and is very responsive. The
rudder is very effective. Stalls are a non-event, as the plane gives a good
amount of buffet before the stall, and mushes along rather than having a
distinct break.
The Corvair engine sounds like a REAL airplane engine. I really like the
direct drive, air cooled nature of it. They are currently running the
engine at a maximum of about 3200 rpm. Im not going to talk about
airspeeds since I would like William to post something a little more
scientific than my one observation, but the engine seems to deliver
horsepower that is in line with the other 100 hp engines people are using.
It was certainly enough engine for this plane.
The rest of the afternoon, I spent asking questions and poking my nose into
their projects. Something Im sure not many other people would let me do so
readily. I saw the dyno set-up, the engine he has for sale on the web site,
the Wagabond, the Cigarette Boat, and many other creations, but the best
part is just sitting and asking questions. William was very open to
answering even the most stupid of questions I had, and in fact, spend a
couple hours doing so!
William and crew: thanks for a great day and thanks for making a 100HP
engine affordable for most people. That is the sprit of EAA, and you guys
live it out every day.

HEHEHE you are correct. sorry, I did not read his reply to my post
correctly. He said left wing and I was talking about the right wing so yes,
we were both saying the same thing. To many long days with no sleep I guess

What am I missing? Aren't they saying the same thing?

Thanks for all the great advise!
I don't like the extra cost of the capacitance senders but figure less
trouble in the long run, much easier setting up and no moving parts.
Scott, did you have to work at making sure your tanks were low against the
bottom of the nose skin or simply centered top to bottom on the spar?
Zed, thanks for the 20mm.....exactly the dimension I needed. Now I can make
up a +/- 25mm puck blank and "play" with the skins without first chopping up
my tanks. I may still go with the side mount and bendable probes (like
yours, Ron) so I can access the calibration buttons through the finger
screen access covers.....
For plumbing four leading edge tanks in an XL, has anyone tried tying the
two mains together on one valve position, the two aux on another, so a pair
would feed together - both mains or both aux - with only one tank in each
pair gauged? Seems there's less risk of losing track of which tank you're
switched to - only two positions to choose, main or aux, cuts cost of
senders and gauges in half...and you would still rely primarily on visually
monitoring pre-takeoff tank levels and fuel burn for actual planning and
switching. Added benefit of inherent fuel balancing across the wings. I
see some gotchas but would like to hear if anyone has tried it or thinks it
could work. It would always be easy to split them back out at the selector
valve if feed problems arose, but lack of senders in the 'other' tanks would
then be an issue.
Any thoughts?

Since I'm pretty sure you have the same cowl as mine, thought I would tell you
what I used. The primary studs were the AJ4-25 (since you are not dealing with
a
whole lot of thickness) and the S4-200 spring for the cowl to aircraft attach
points.For the lower to upper cowl (due to it bieing a little thicker) you may
want to use the AJ4-30 stud and S4-225 spring. With out going out and checking
receipts I do remember that I did use a combination of both (though leaning
towards the shorter where possible, just need to take a few measurements). I
also ordered sufficient numbers of the GP4B "half grommets" to protect the paint
from the studs and SR4SS snap rings to hold the studs in place. One thing I have
found, the hole in the part the stud is in needs to be real close to the stud
diameter, and the hole through the part where the spring is located should have
a little slop (maybe quite a bit of slop) so that the studs will come out when
you want to take the cowl off. Otherwise they hang up and you have the move it
around a bit to get them apart. The rivets needed to hold the springs in place
will be 3/32" diameter. If you need I can look up the part number on them. Send
me a couple of pictures when you have it done. I'd like to see how it comes out.
In fact I will be laying up another lower cowl sometime in the next couple of
months to replace the one that got broke on mine. Guess you sometimes don't get
finish building. Later

Jeff,
Your first note said lower rear of left wing and heavy left wing. FWIW.

I thought that might work too, only to find out later by those who know
more about this stuff than me, that the problem would be one wing's tank
could empty before the other one, which would cause air to be sucked into
the system. Most (including ZAC) advised that each tank be independent.

| Subject: | Aileron trim tab |
--> Zenith-List message posted by: "Jeff Paden" <jeffpaden@madbbs.com>
This is why I love this list so much. I have a few thoughts about aileron
trim tabs so I'd like to ask everyone on the list to let me know your
opinion please.
First, I now have my aircraft so that it flies level. However that is with
me flying alone. What happens later when I put a 200 lb passenger in the
co-pilot seat? I have a feeling that when I do that the aircraft will want
to roll to the right a bit.
So, my question is this, shouldn't the aircraft have been designed with an
aileron trim system?
And now that I have already closed up my wings and painted the aircraft does
anyone have any good ideas
for an in-flight or ground adjustable trim tab for the ailerons?
I have read in the archives about the fixed trim tab and I had one of those
on my CH300. I was not impressed and since it could not be adjusted I found
that when I had passengers I had to hold the stick to the left a bit.
Any and all comments will be appreciated.
Thank you

N640JP first flight
Jeff,
Congrats! Know you are glad this is completed! I really doubt if you are
off 3 degrees on that wing, I think that would make a very very heavy wing. I
thought you built it that way so you wouldn't have to hold so much Rt Rudder
with all that power during climbout :-) Now you have to quit smiling!!
Glad to hear you are in the air~
Let me know if you have any questions on the RiteAngle set-up.

Jeff,
A 601 (mine has a trim tab) is lighter than a 640..but would a 640 really need
aileron trim as much if at all since it is 'bigger'??
