Re: LS1 Foam Layout. . .
Yes, you are correct that the shape of the wing is altered doing this, but the core templates are shaped to compensate.toggle quoted messageShow quoted text

This is a response to Rick Hole's OFFLIST message (Show below). Rick
if you send an e-mail to Q-LIST_at_yahoogroups_dot_com it will be posted
to the Q-list automagically. ;-)
The problem is that the LS1 plans aren't very precise. They seem to be
an addendum to an addendum, with various references to the Q2 plans.
The Q2 plans say that you line the T.E. of the templates to the Squared
off foam block, but it also says that you can leave the trim lines
dangling off the end of the foam if you want. So that leaves some
wiggle room fore and aft.
Then it doesn't really say how to align the templates vertically from
end to end. Except an obscure reference to "Water Lines" in the
Education Chapter (3). There are no offsets or exceptions listed on the
templates, and no vertical dimensions given. Just a rough sketch of the
GU canard templates tacked to the ends of the foam, with no precise
If the templates cut the foam perpendicular to the wing, and then the
wing is swept back, and anhedral is added, doesn't this change the shape
of the airfoil to the relative wind (Along BL0).
I know that the templates seem to have worked fine for many of you, and
they resulted in several beautifully flying airplanes. I'm just
wondering how people actually cut out their canards, and get my head
wrapped around it. I'd like to write an article that makes the process
a little more precise than shown in the "instructions."
I appreciate your input.
