The LS1 plans addendum leaves something to be desired and is lacking in some
detail. You need to read both sets of plans for the method to make the
canard. If you have figured out how to cut the cores using the LS1
templates, the section BL00-BL15 is just a matter of cutting the billets to
fit together in the cente. It makes more sense when all of the cores are set
up on the spars which are joined and held in the bench jigs. (Do it dry
first !). When ready to micro the cores onto the spars I found it is
important to get the slurry right, not too stiff. Otherwise the cores will
not bed deep into the spar and spar diameter is close to core thickness for
part of the length. You don't want to find the spar exposed when it is time
to sand down the airfoil.

Please allow me to appologize. I must not be communicating my
question very well and I'm sorry.

I understand that the Q-200 uses the LS1 airfoil and a carbon spar
for the canard to fix the bug/rain problem with the GU airfoil and to
add extra support for the heavier 0-200 engine. So, here I am with the
LS1 templates in hand and ready to cut my foam cores. I pour through
all the documents that I've collected on the Q2/200 trying to find any
specific instructions for cutting out the "LS1" cores and I find none.
I've looked through the Q2 Manual, the LS1 Addendum, and Q200 Plans
section II (and I did a fruitless search in this yahoo group). The
closest thing I could find was in the beginning of the "LS1" Addendum
where they say the canard cores from BL0 to BL15 are cut into two
pieces instead of one. So I'm *assuming* I should cut the LS1
BL15-BL100 cores the same way as the GU cores would be cut. (I'm NOT
cutting GU airfoils).

Again, I appologize. Assumptions make me uneasy, especially
considering the magnitude of the project. All I wanted to do was
double check that I wasn't missing anything before I cut into my
expensive foam. I didn't mean for it to turn into a big ordeal.

You can't just use the Q2 airfoil templates!! ), different

different fuel system plumbing, and different aileron control system

There is not just one article or web page, there are entire websites
