WING CONSTRUCTION
The first thing to do is to sand all parts that will be glued; I used 80 grit sandpaper to remove the paint from the Fuselage
and then cleaned it with cleaning alcohol (denatured alcohol). The wing spar will need to be lightly sanded and so will the
wing; you may elect to remove some of the covering where the wing glues on to the fuselage. This is left to the discretion
of the builder. My Fuselage did not have a slot for the Aileron servo wire to go through, I used the wing to measure out
where the servo would exit and cut a slot. NOTE: When I received the F-20, the wings had already been glued to the
fuselage, I will use some pictures from the HET F-16 as reference.
PICTURE ON LEFT: The example above is from the HET F-16, but the procedure is the same. Sand the Spar lightly and
I used 30 minute epoxy, I used a small stick that can push epoxy inside the wing and provide glue all over the cavity in the
wing.
PICTURE ON RIGHT: Do not try to force the wing spar too far into the wing; you should feel it stop once it reaches
about 50% into the wing, clean off excess glue from where the spar meets the wing. Notice that there is no access for the

nt already; this is the perfect time to cut one out.
PICTURE ON LEFT: The whole cut out after the wing was joined, it is best to cut it on the fuselage and the wing before
you glue the wing on the body.
PICTURE ON RIGHT: Test fit the wing with the Spar in place and make sure there are no GAPS before you glue the
wing to the fuselage. Trim the spar if needed. NOTE: Carbon Fiber Spar is very brittle, sand or cut the spar with dremmel
and cut off wheel, DO NOT use pliers, scissors or anything that will compress (crunch) the spar. Once you are satisfied
with the fit of the wing, glue the wings to the airplane with 30 min epoxy or glue of your choice.
