pREpARATION
1. Lay three or four paper towels over each other and cut
the stack into small squares. The small paper towel squares,
dampened with denatured alcohol, will come in handy for
epoxy cleanup and other general cleanup during assembly.
2. Remove the masking tape holding all the control
surfaces to their main parts. If necessary, clean off any
residual tape glue with a couple of your paper towel squares
dampened with naptha (lighter fluid).
3. Using a sealing iron, remove any wrinkles in the
covering before assembly.
ASSEMBLE THE wING
1. Using 220-grit sandpaper, remove any excess glue
from the sides, top and bottom of the aluminum and plywood
wing joiner. Clean the wing joiner with denatured alcohol and
a paper towel.
2. Check the fit of the wing joiner in the wing panels.
Remove any excess material from the joiner to allow the
panels to fit together. Gather everything required for gluing
the wing joiner and wing together including, 30-minute
epoxy, mixing sticks, epoxy brush, 12" [304mm] long dowel
or wire, denatured alcohol and paper towels. Mix up 1/2
oz. [14.8cc] of 30-minute epoxy. Working quickly, pour a
generous amount into the joiner pocket of one wing half.
Use your wire or dowel to thoroughly distribute the epoxy,
coating all surfaces inside the joiner pocket. Coat the root
rib and one half of the wing joiner that goes into the wing.
Insert the joiner in the wing. Coat the joiner pocket in the
other wing half and the other end of the wing joiner. Join the
wing halves together. Then, stand the wing on end with one
of the wing tips resting on the floor. Use a piece of R/C foam
or something similar to cushion and stabilize the wing so it
won’t slide around. Hold the two wing halves together with
masking tape. Wipe off any excess epoxy with a paper towel
dampened with denatured alcohol.
