The easiest type of carbon to use is the Unidirectional Carbon Laminate
strips the same width as the wooden spars in the wing. Typically they
are only needed in the center part of the wing. Just glue them on the
top and bottom (outer surfaces) of the wooden spars. I recommend thick
flexible type
You might look into the premade material. from either of your sources. I
have some .007 material that is 1/4 wide and plan to bond this with WEST
systems to the spar caps. It is avail in many widths and several
thicknesses, even tapered I believe.

There's another carbon product you might consider - Jim Marske* sells
Graphlite, a very high modulus carbon (rod, rectangle). I had a scale
builder recommend it, and it's pretty great. I bought a roll of it
(like working with spring steel), and I've been using it for a couple
years now.

A word of warning Douglas.
Carbon fiber dust is a very bad substance to get into your lungs. When you
cut it with a dremel you should, at a minimum, be wearing a filter that
prevents the dust from entering your lungs. At best, you should be doing it
in an environment that doesn't leave the dust
Here's a good article Jim put out

Hi Wes,
I am in the process of building a Majestic. Mark Drela has
provided a series of suggested modifications for the Majestic, one of
which is to add carbon fiber to the spars. For this 110-in.-span
plane, he recommends tapered carbon fiber
Look in R/C Groups/Sailplanes/Thermal and find the
original Houston Hawk thread. In the first 100 replys
there is a good system shown for spars of the Houston
Hawk. It's a 126 RES ship and the winf has so far
proven winch proof. I used .060 top and .030 bottom
caps with no spruce. I wrapped only
Wes. . .it will be easiest to work with the rigid, pre-made laminated spars.
They come in several lengths, widths and thicknesses. If this is a 2M RES
the .014 thickness should be fine. If somewhat larger, a bit thicker would
be better. You do want these to be flush with the top and bottom of
