The following step should be performed with the radio
on so the servo arm remains centered.
8. Once you've confi rmed that everything operates correctly,
tape the aileron centered to the wing, then glue the servo into
position—it's not necessary to "glop" on lots of glue—just a
medium fi lm is all that is required. No clamping is required
either—simply press the servo down to the wing. Once set
into position turn off the radio. Check the servo a couple of
times over the next ten or fi fteen minutes to make sure it
hasn't moved. After that, let the glue dry overnight before
testing the ailerons.
9. After the glue has dried, turn your radio on and adjust
the pushrod in the screw-lock connector so the aileron will
be centered. Lock the pushrod down with the screw and a
small drop of threadlocker on the threads.
10. Tape the hatch cover to the wing with clear tape.
Build the left wing the same way.

1. Cut the covering from the notches in the leading edge
of both wing roots for the leading edge carbon fi ber peg.
2. Scuff the joiner rod and one of the two carbon pegs
with medium-grit sandpaper so glue will adhere. Test-fi t the
wing halves together with the rod and peg—the halves should
align with each other and fi t together tightly with no gaps.
Make any adjustments necessary for a good fi t.
3. Cut a couple of paper towels into small squares for
wiping up excess epoxy in the next step.
4. Apply 30-minute epoxy to all joining surfaces including
all around the joiner rod and down inside the tubes in the wing
and join the halves together. Install the peg into the leading
edge. Then, use the small paper towel squares dampened
with denatured alcohol to clean up excess epoxy. Use masking
tape to tightly hold the halves together until the epoxy hardens.
