recent RC Car Action recommended G-10 fiberglass material for making new
shock towers.  i called several places for this and i was quoted over
$80 for a 3x4' sheet.  

has anyone used something else for less?

Hey, try and find an old chassis that you can hack up. If you don't have
an old chassis (THIS is why you keep old, bent chassis', but I'M a
pack-rat), head down to the hobby shop, alot of times, they will have a
box of old junk nobody needs anymore, stuff they couldn't sale. Maybe
something like a chassis for a Bolink Invader...'member  those? Anyway,
try old RC parts, because as you've found, buying carbon fiber, and G-10
by the sheet is expensive, because not many people sell little pieces
like we need. Another idea, is to find a company who uses G-10 in
manufacturing in your area, and ask about scraps. Try a boat yard, LOTS
of fiber glass hulls! Try talking to the people in the boat
shop....well, I'm rambling...hope this helps.

I actually have some carbon plates curing in my oven
right now because I broke the front tower on my rc10
today.  I get the prepreg free from iss contractors
and such because MIL specs require an expiration date
on prepreg.  Once expired they can't use it.  The
expiration is just a formality really, if you keep
it cold it lasts almost indefinately.  Stiffer, stronger,
lighter, and cheaper than anything you can buy.  I've
also made rc10 chassis with stiffening ribs from S glass
that weighed less than 1/2 what the commercial graphite
chassis I have weighs.  If you know someone in the
defense or space industry they can probably hook you
up with some free scraps.  SImply peel the backing from
the prepreg and make a plate however large and thick
you need and put it between two stiff metal plates and
toss it in your oven overnight at 350F or so.  Typically
you can expect 0.01 inch of  thickness for each layer
of material.

Actually, I wrote that article, and I've found that G-10 scraps are
pretty easy to find.  Look under 'Industrial Plastics' in the Yellow
pages, or on the Web, and you should be able to find places that custom
cut G-10 and other materials (like nylon or delrin) for customers.  They
keep the scraps (perfect size for us RC folks) and sell them for a buck
or so.

Try Read Plastics in Rockville, MD.  I don't know if they do mail order,
but they're pretty big, and I've been buying stuff from them for over ten
years.

Good Luck!
