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 approximately perpendicular to
the servo side. Use the transmitter’s sub trim to make it
perpendicular.
Gently snap off the servo wire installation string. Do not
pull it out of the wing. Attach the servo wire to the
installation string and gently pull the wire through the
wing as you insert the servo into the wing.
Connect a servo extension wire to the servo lead if
needed. Use a safety clip to secure the connection.
Insert the servo into the pocket with the drive spline
towards the front of the wing. Pre-drill for the servo
mounting screws using a 1/16” drill.
Remove the servo
and apply a drop of thin CA glue into each mounting
screw hole. This will harden the wood around the screws
and provide a more secure installation. Allow the CA glue
to dry before reinstalling the servo.
Assemble the connecting rod to a servo arm ball link and
to the control horn ball link. Notice that one end of the
connecting rod is a left hand thread and the other end is
a right hand thread. Screw the connection rod into each
ball link equally. (A small drop of oil may make help the
threads cut into the ball link.)
