❏
1. Tape the bottom of the two wing panels together with a
single piece of tape. Make sure the leading and trailing edges
are lined up, and the wing panels are tightly butted together.
❏
2. Flip the wing over, and lightly coat the shaded area
shown with epoxy. Lightly coat the bottom (unpainted side)
of the plastic wing joiner as well.
❏
3. Prop both wing tips 1-1/2" [38mm] off your work table.
Press the wing joiner down onto the joint of the wing, being
careful to keep it centered. Place a small weight on the
joiner to hold everything tight. Allow the epoxy to harden
before proceeding.
❏
4. Use 6-minute epoxy to glue the foam wing joiner to the
bottom of the wing. Make sure that it is centered and that the
leading edge of the wing is lined up with the front of the joiner.
❏
5. Screw the 3 x 20mm wing mounting screw all the way
down into the plastic blind nut in the fuselage.
❏
6. Test fit the wing to the fuselage by slipping the tongue
at the trailing edge into the fuselage first. Then press the
bottom joiner into the fuselage cutout. It should fit somewhat
tightly. Making sure the wing is properly aligned, press down
on the center of the wing near the leading edge. This will
leave an impression of the wing mounting screw that we will
use as a guide for drilling.
