To my friends on all the Matronics lists that have helped me in many ways
over the years.
Some of you I have met in person, so many that I have never met but have
been with me
through this project since 2002.
I just want to say thank you for the encouragement, help, sound advice, in
formation, photos, drawings, parts, ideas, techniques, web sites, lessons
learned, stories, debates, Scotchbrite advice,humor and especially the fr
iendships.
Many of you don't even know how much you've helped, but your contribution
and presence on the lists
have been a tremendous help.
Yesterday, I had my inspection completed and received my airworthiness cer
tificate. I'm surrounded by
many experienced pilots at Spadaro Airport in Long Island, NY to help me
through the next phase of this
adventure/dream/crazy idea. Thanks Matt Dralle for making it all happen he
re.
I especially want to thank these people from the lists.

| Subject: | Re: 601XL fiberglass wingroot fairings |
I'm fabricating top and bottom fairings for my 601 XL. The airplane isn't finished
yet, but from an aerodynamic point, it is evident that the fairings should
help quite a bit. It doesn't take a huge amount of specialized skill, but does
take more time than I expected. I fastened 1" thick foam sheets (the foam that
the QB kit was packed in) to the airframe with double sided tape. That type
foam isn't the best for forms because it isn't very dense, but it was available
and I had no other use for it. Additional sheets were stuck to existing sheets
with double sided tape or small dabs of epoxy adhesive. The foam was shaped
with Stanley Sureform files, sandpaper, hot wire foam cutter, electric chainsaw,
etc. Irregularities, and gaps, were filled with modeling clay. Then, I coated
the foam with epoxy for stiffness. After that was cured, I covered it with
duct tape and made sure the duct tape was extended a few inches outside of the
fairing area so no epoxy would get on the skin. Epoxy doesn't stick to duct
tape, but some mold release on the tape helps with de-molding. Mold release can
be paste wax, or even spray on cooking oil, or Pledge furniture wax.
Cut the glass or carbon fiber cloth to shape leaving plenty of excess on the edges.
I put a coat of resin on the form using a small roller or brush. Lay the
cloth over the form and work the cloth into the epoxy on the surface. Use more
epoxy if you have to for wet through, but not too much. If you use a brush, cut
off about 1/3rd of the length of the bristles so they are stiffer. Push the
cloth into the epoxy with short vertical jabs called "stippling". There shouldn't
be so much resin that it puddles, and the weave should show. I used three
three layers of 6 oz/sq yd carbon fiber twill cloth. Glass cloth is less expensive,
but heavier and not as stiff. It's likely you can't make the layup in one
piece as it gets quite unwieldy. Overlap the separate pieces by about 1 1/2".
Leave the layup on the mold until the epoxy has fully cured. This might be
a couple of days. De-mold by starting on an edge by working a putty knife under
and edge and getting it lifted. At first it will appear to come off with difficulty,
but after some has broken loose, it's likely the part will fall off.
Making a part from a male mold as I've described will leave a somewhat uneven
and rough surface. Depending how you want to finish the fairing will determine
how it's made smooth. If painting, use a lightweight filler made from epoxy and
microballoons (glass beads). You could use lightweight polyester body filler
too. Then sand and paint. I made mine from carbon fiber cloth and intend to
leave it natural. I painted on another coat of epoxy to fill the weave and sanded
most of that off. Another coat of epoxy and more sanding using finer grit.
I'll finish with urethane automotive paint clear coats for UV protection with
sanding between coats.
Polyester resin could be used instead of epoxy. Epoxy doesn't shrink like polyester does, and epoxy is a much better adhesive than polyester. I used epoxy that is good to over well over 200 deg F since the top fairings will be out in the sun. I used epoxy system 2000 from Fiberglast. http://www.fibreglast.com/ They have hardeners in 20 min, 60 min, and 120 min setting time. Epoxy resins are available from other sources that will work too.

Congratulations Brian! And thanks for the mention! It is a special day
when one builder reports his first flight and another getting his
AirWorthiness Certificate!
