37) Tape the wing panels together at the root with the
bottom edges aligned as shown in Photo 34. The tape
should be on the bottom edge.
38) Set the wing panels on a flat table with the tips each
blocked up ¾”. Open the joint at R1 and epoxy them to
one another, then set them back down on the blocks.
TAKE CARE TO ENSURE THE WINGS GO
TOGETHER IN PROPER ALIGNMENT!
39) Once the epoxy has cured, remove the tape from the
bottom of the wing. Sand the root joint of the two
wings so the edge is smooth. Measure a piece of the
fiberglass tape so it is a little longer than the bottom of
the wing. Center it on the bottom of the wing, and use
thin CA to glue it down. See Photo 35.
The CA will wick into both the wood and cloth. After
you have attached it, spray with accelerator –
sometimes large amounts of CA don’t cure well.
Avoid the fumes – this could get pretty warm and put
out a lot of noxious gas.
40) Trim the excess glass tape from the LE and TE. Lightly
sand the glassed area to blend the edges into the balsa
smoothly.
41) Glass the top wing joint as you did the bottom.
42) Cut a hole in the area between the root rib R1 and R2.
This hole will be used to thread the servo lead through
later.
43) Now it is time to cut out and finish the ailerons. Trim the
ailerons so they fit within the cut-outs in the wings.
44) Mark the aileron 1” from the root as shown in Photo 37.
Cut out an area ¼” x 1/16” to accept the control horn. The
horns extend out the bottom of the wing, and the control
horn is angled a bit so you will need to cut the notch at an
angle so it fits properly as shown in Photo 38.
