Just shoot me. I have to figure out how to make "plain text" the
default on this goofy web interface, if it's possible. See below...
I should add to this that given that you are putting holes in it,
plywood core does make perfect sense, and I would laminate it all
together and then cut the hole
Let me try that again...this time as "plain text" so it won't post a
blank.

Hay Mark,
I'm getting ready to order my carbon fiber,I know you used cf on your wings and
it seems your happy with them.I guess the question I have is,How many layers
did you lay up, and what weight did you use? I think I'll just order it from
Wicks @ 33.12 per yard unless you can think of a bet

Carbon fiber is known for it's stiffness, but what you want in a gear leg is
just the opposite. I don't know of anybody that's using a carbon fiber gear

From what I have been able to glean from various articles and

I am working up my horizontal and vertical stabilizers and was planning to

Does anyone that is going to the Gathering have a 12 x 12 inch ³scrap²

It is not that carbon fiber is lighter, it is that it is 5 times stronger than
the same single lay up of regular E-glass, so it would take 5 layers of E-glass
to equal one layer of carbon fiber. There is where you get either light
