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.
5. Attach the aileron control horn to the aileron with
two #2 x 1/2" [13mm] sheet metal screws. Remove the
screws and put a drop of thin CA in each hole to harden the
wood. After the CA has hardened, reinstall the control horn
with the screws.
6. Center the aileron servo arm and mark where the
pushrod crosses the arm. Make a 90° bend at the mark, cut
the pushrod and attach it to the servo arm with a Faslink.
7. Return to step 1, Install the Aileron Servos and
install the other aileron servo.
