Thanks Dan,
The 601 in question is a plans project. The builder's approach was to
fabricate the sheet metal parts for the entire project before riveting
any of the sub-assemblies. The fab work is mostly done so it's really
like buying a kit at this point. Based on what I've read I think I'd be
in good shape for the amateur-built classification.
Thanks again for you response!

There actually is a use for the split master in our 601/Jabiru
application Jeff. The side that is intended to send power to the field
of the alternator can be used instead to activate a continuous duty
relay between the permanent magnet alternator's regulated output and the
positive terminal of the battery. Serves the same purpose without any
big drawbacks.

sense with the single phase alternator.

Hello group ,this is somewhat Zenith related at least to the Cont.0-200
powered people.When flying my 0200 Sonerai in this Texas heat my oil
temps climb to the red line of 220 degrees and seems to stay there . Now
my Tripacer with the 0320 Lyc. is red lined at 245 degrees .Sometimes I
fly the Tripacer at 230 degrees 15 short of the red line .Both engines
being built similar using the same type and weight of oil should I be
concerned with the 0-200 say heating to slightly above the red line temp
,remember I am using the engine in an experimental . Wade Jones

| Subject: | 601XL Rear Spar Reinforcement Idea |
Gang:
There has been some concern about the unexpected in-flight failures of
various 601XL's. As an experienced (Ph.D. + 25 years) aerospace
engineer,
I am tempted to brush these off as "cause unknowable" due [1]to the
large
number of unknown variables in construction, maintenance and operation
of the
accident aircraft, and [2] the lack of available data about the
accidents
themselves. That is my "official" opinion.
A few people have asked me about this, however, so I took a good look at
the
1/2 built wings in my garage. Knowing that the wings have passed static
proof
tests, I looked mainly for what you might call "less than optimal"
design
features, including places in the design where a reasonable error in
construction might lead to a more serious condition.
The only thing I found was that the clearance hole for the aileron
pushrod is
rather large and is located rather close to the rear spar lower flange.
It would
be easy during construction to make this hole closer to, or even touch
the flange.
Since the top and bottom of the spar carry the large part of the wing
bending
load, this *could* weaken the spar.
NOTE: This is an analytical discussion, not support by experimental
evidence.
In engineering one often lacks complete data, and in those cases you
look for
ways to mitigate risk. If the cost of mitigating the risk is large,
you may decide to do more extensive analysis or experimental testing.
If the cost of mitigating the risk is small, however, you might just
decide
to go ahead and do the fix regardless. That is what I chose to do.
So I cut a piece of .025 standard angle to a length will cover the three
A5 rivet holes in the bottom flange on both sides of the aileron pushrod
hole.
I bent the piece to match the angle of the spar flange, then trimmed it
to fit
flush with the flange and also to clear the exit hole. Finally, I match
drilled
it to the spar, deburred and primed.
Complete details and pictures of this "fix" are available on line at:
http://members.cox.net/n601ge/drawings/rearspar.html
This small doubler strap reinforces the flange in that section of the
spar, and
thereby helps transfer wing bending loads across the hole. It has many
good
characteristics:
* It takes about an hour to make and install.
* Installed, it is invisible.
* It does not interfere with aileron operation.
* It weighs approximately nothing.
* It costs approximately nothing.
* It can be easily retrofit to completed wings.
and no bad ones that I know of, and therefore fits the requirements
for risk mitigation, IMHO. So I'm putting them on my plane. If you
think
differently, please do not put them on your plane. If you think my
analysis
is flawed, please correspond with me off-group.
All standard disclaimers apply, etc. FWIW,

| Subject: | 601XL Rear Spar Reinforcement Idea |
Andy,
Your reinforcing looks reasonable. Just don't forget that, on the inboard part
of this reinforced area, the flap hinge will go between the bottom skin and the
bottom flange of the rear spar. And that hinge won't be riveted until much
later.
On my particular airplane, the drawings called for a 38mm hole, 20mm from the bottom
of the bottom flange. That leaves less than 1mm between the hole and the
flange. The hole was later changed to a 32mm dia., leaving about a 4mm clearance;
which I suspect is what you have. I might measure the clearance between
the flange and the control rod end to see if I can partially cover the hole
with the reinforcing angle.
Instead of trimming the vertical leg fo the doubler angle, I think I would only
notch it (at the hole) and put some A4 rivets into the web of the spar to help
resist buckling of the doubler angle.
Just my 2 cents worth.
Jay

This just my opinion.....
I don't like to see oil temps below 210 and prefer mine to be about 230-
235 on climb out and drop to 220 or so during cruise. The formulation of
premium oil now a days work better at elevated temps. I try not to even
take off till I see 150 oil temps. There are several RV guys around her
e who love to brag that their oil temps run under 180,,, Geez the stuff
is not even thinned out properly yet at temps that low. Your mileage m
ay vary....

I hesitate to ask but does anyone know the status of Scott Laughlin's 601XL
project? The last update on his website was on May 27th and said he was
ready for FAA inspection. Since then, nothing. It is such a beautiful plane
it is hard to believe the inspector found much to complain about.

Glad to hear it. Do you have any way to measure the angle of the plane
defined by the disks at the back of the mounting pins relative to the plane
defined by the plates that bolt to the firewall? That (and the angle of your
firewall to the upper longerons) are the critical numbers.

Hi, Craig
I exchanged a couple of notes with Scott a few weeks ago (early July).
He said he was busy with non-aviation related issues, but would post a note
after his first flight.
I guess it didn't happen yet, for one reason or another.
