4. Thread a nylon clevis approximately 14 full turns
onto the threaded end of a 2-56 x 4" [102mm] pushrod.
Slide a silicone clevis retainer over the clevis. Remove the
backing plate from one of the large control horns and
connect the clevis to the control horn. Position the control
horn on the aileron so that the adjustment holes are aligned
with the aileron hinge line and the pushrod is parallel with
centerline of the servo. Mark the control horn mounting hole
locations on the aileron.

two #2 x 1/2" [13mm] sheet metal screws. Remove the

wood. After the CA has hardened, reinstall the control horn
with the screws.
