List,
Has anyone devised an easy way to sand the paint around the drilled out rivets.
Also will it be better to paint just around the rivets and try to blend the paint
or sand the whole part and paint again??
If primer is used around the sanded area it will take more coats of paint to cover
and hide the color.
Any ideas?
Bobby

Mike, I picked up my upgrade kit yesterday from Zenith. I asked Roger the same
question and his reply was that the fuselage stiffeners are NOT part of the upgrade.
He had "some time to spare" and it only took him four hours. You will
have to purchase additional stiffeners to do the fuselage mod.

Mike, when I asked Zenith on the forum page if the fuselage "L" stiffners were
a part of the modification, I was told they were not. Thus, I would be very
surprised if the material to do this is present in the parts package.
Zenith is saying that this is something you might want to do, not something
that must be done as a part of the modification.
The discussion on the forum to which I refer can be found here:

Most of the time, aluminum isn't sand blasted, because it removes the
protective layer of aluminum at the surface of the material. The best bet is
probably paint remover. When that's done, a wooden craft stick can be used to
scrape the paint from around the rivet.
It's a tedious process, but it's better for the metal.
Whether you repaint the whole thing, or just touch it up seems to me to be a
personal call. It's probably going to look better it if it's totally stripped
and repainted. But that's a lot of work. I doubt Zenith went that far on their
demo aircraft.

Hello guys!
Back in classes today for the first time this year...
With no Zenith upgrade kit in hand and no date offered for delivery, I canceled
it.
I am currently working on a nearly invisible (from 50') externally braced reinforcement...
the vast number of hours required to install an internal kit that
has not been proven to be or even claimed by CH to be a cure for the structural
failures is a key reason... so too, I started this project as an educational
experience and I don't see much educational value in tearing down my aircraft
and reinstalling parts that are just that much thicker when I can (hopefully)
design an easy to install externally braced alternative...
So too, my center spar and forward fuselage is so heavily modified with aluminum/foam/aluminum
reinforcement, to remove those modifications in order to install
Zenith's would add a hundred hours to the process, possibly damage the outer
skins beyond repair, and may prove no stronger.
My Phase 1 flight envelope will be limited to a small portion of the class Delta
airspace over my airport, but I can live with that.
For those with open cockpit experience, what do you think of flying an XL based
aircraft with the canopy removed (full face motorcycle helmet and parachute,
of course)? It would save me the 10-15 seconds it would take to eject the canopy
before jumping in case my calculations on the external bracing were wrong.
For those of you who have ridden a motorcycle at 120 MPH, how much different is
it than 55MPH?

Subject: | Do the 601 problems extend to the UL |
I am in the final process of negotiating a purchase of a 601 UL. From what I have
read so far, the model with the structural problems seems to be the XL model
(except for the UK crash, which was attributed to pilot error). Am I right about
this?

Hi Sabrina,
I know you are not doing it on purpose, but you are going to make me worry
about you. I know you don't want to take your plane apart and install the
changes, but I hope you reconsider this and decide to do it anyway. While
the real usefulness of the changes is subject to question, I feel it is a
really good idea to use it. The accidents don't have much in common except
all the planes broke in the same place. That is the area that is getting
beefed up.
Maybe you would consider writing to Chris and asking him about your changes
vs. the ones he blessed. It could be he knows more than he is saying . . .
If you want to fly your Zodiac open cockpit, I suggest you install a
windshield. I have not ridden a motorcycle at 120, but I have done it over
90 and I can tell you the wind is noticeable.
I also hope we all pay attention to the experience of the modified Zodiac
XLs. If the accidents go away then I will be convinced the changes did some
good.
Paul
XL awaiting upgrade kit (promised some time in February).

I would be great if Zenith or AMD put out extensive videos of their test flights
like RV and published Dynon G meter logs on their upgraded aircraft... Are they
testing to +6/-4? +4/-2?
I fear more harm than good will come from opening her up. I am told that the only
common maintenance thread in every crash is that the wings were removed at
least once after being fully torqued in place. My aircraft has had the wings
torqued in place just once, and I plan on keeping it that way for now.

Don't forget the scratch build alternative to save some bucks on the L-angles.
For the price of 2'x4' sheet of .025 6061-T6 from ACS ($17), a 2x4 stud
from your local lumber yard ($2), and 5 4"-C-clamps from Harbor Freight
($25), plus your trusty Olfa cutter, you can produce 64 ft of L-angle in a
matter of a few hours using Craig Payne's technique as published in Zenair
News #169. If you've got a 4' brake, it's even easier. Craig's clever idea
works like a charm. I've even modified Craig's dies a little to try to make
Z-angle. If it works out, I'll write something up.

How about a front windshield and open canopy, a la WWII Navy fighters?
You get the best of both worlds. You might also want to close off the

The last I remember, FAA approved media for blasting aluminum were things like
ground corn cobs and nut shells. I don't remember if glass beads were on the
list or not.
A spot blast mask such as you suggest would be a good idea.

Sabrina,
120mph on a motorcycle puts a great deal of pressure on you. Try to deflect the
wind away from your head and shoulders. A partial windscreen with bracing should
suffice and still allow a quick exit if necessary.
Perhaps you can find someone who has a fractured canopy and you can cut what you
need from it.
