Apply epoxy to the slot in the aileron. Use a pin to help
push the epoxy in.
Apply epoxy to the control horn and insert it into the slot.
Wipe away excess epoxy using a paper towel and
denatured alcohol.
Check the alignment along the hinge line as you did when
you test fit the control horn. Reposition as needed.
Allow the epoxy to partially cure. Peel away the masking
tape after the epoxy is securely holding the control horn
in place and still soft enough to easily remove the tape.
Set the wing aside and let the epoxy fully cure.
Connect the servo to a receiver and power supply. Turn
on your transmitter. Set trim and sub trim to zero. Install
a servo arm on the servo about perpendicular to the
servo’s side. Use the transmitter’s sub trim to make it
exactly perpendicular to the side of the servo.
Attach a servo extension and a safety clip to the servo.
Attach the servo wire to the installation string and gently
pull the wire through the wing as you insert the servo
into the wing.
