Step 20
Attach.the.control.horn.using.three.#.x.3/4".
screws.and.the.control.horn.backplate.
Note
:.Cut.the.excess.screw.extending.from.
the.control.horn.backplate.using.side.cutters.
Step 21
Slide.a.clevis.retainer.onto.a.nylon.clevis..Thread.a.clevis.
onto.a.6".(153mm).pushrod.wire.a.minimum.of.10.turns.
Step 22
Center.the.aileron.servo.electronically.using.the.
radio.system..Attach.the.pushrod.with.clevis.to.
the.control.horn..Physically.place.the.aileron.
control.surface.in.neutral..Mark.the.pushrod.
where.it.crosses.the.holes.in.the.servo.arm.
Step 23
Bend.the.wire.90.degrees.at.the.mark.made.in.the.
previous.step..Cut.the.wire.3/8".(9.5mm).above.the.bend.
Step 24
Use.a.5/64".(mm).drill.to.enlarge.the.outer.hole.
in.the.servo.arm..Slide.the.wire.through.the.hole..
Secure.the.wire.using.a.nylon.wire.keeper.
Step 25
