INSTALLING THE AILERON SLOT FOAM CORES
..... This step is critical to having a nice looking main wing and
aileron union, so follow the directions carefully.
..... To start out with, the aileron slot foam cores that you hot-
wired way back when were purposely made longer than necessary. Your
first task is to size them for the correct length. To do this, you
must measure your fuselage width at the fuselage/aileron slot foam
core junction. Take measurements of the main wing, skip ahead to the
section on "Mounting The Main Wing To The Fuselage", and determine
that dimension, on either side of BL00. Mark the proper points on the
main wing. Wait to trim the inboard aileron slot foam cores until
after they have been, installed on the main wing.
..... Next, determine where to trim the outboard aileron slot foam
cores. Since each elevator was made 48" long, measure 48" plus 1 inch
(for aileron/ fuselage clearance) from your first mark outboard and
place another mark. This is where the outboard aileron slot foam core
will be trimmed, but, as before, wait until after installation to do
it.
..... Skip ahead to the CANARD chapter, "Installing The Elevator Slot
Foam Cores" section for a sketch showing the geometry of the
attachment. It is easier to check clearances top and bottom if the
main wing is jigged vertically on the jig table. This will also keep
the joint from running. A few scrap pieces of lumber and bondo should
be sufficient.
..... The important point to remember is that at the shear web attach
point along the span, the top and bottom of the aileron slot foam
cores should flow smoothly into the top and bottom surfaces of the
main wing.
..... Once the attachment has cured, trim the aileron slot foam cores
