The.CAP.232G.has.two.options.for.mounting.the.rudder.
servo..For.lighter.engines,.a.pull-pull.system.is.used..For.
heavier.engines.a.tail-mounted.servo.is.used.
The.rudder.requires.a.minimum.of.100.ounce.inch.of.
servo.torque..In.the.prototype.CAP.232G.we.used.a.
JRPS8411.servo.with.excellent.results..Using.servos.with.
less.torque.could.result.in.blow.back.
.
Step 1
Thread.the.8-32.x.4".control.horn.screw.into.the.hole.in.
the.rudder.and.epoxy.in.place..Thread.the.8-32.flange.nuts.
onto.the.screw.from.both.sides.of.the.rudder..Position.the.
screw.so.it.is.centered.in.the.rudder..Use.threadlock.on.
the.nuts.to.prevent.them.from.loosening.during.flight.
.
Step 2
Cut.the.cable.into.two.equal.pieces..Prepare.one.end..
of.the.pull-pull.cable.using.the.cable,.threaded.cable..
end.and.crimp..The.cable.passes.through.the.crimp,.
through.the.threaded.end,.then.back.through.the.crimp..
Pull.the.excess.cable.tight.and.use.a.crimping.tool.to.
complete.the.job.
.
.
Step 3
Screw.the.molded.swivel.link.onto.the.8-32.screw..
until.the.distance.from.the.rudder.surface.to.the.top.of..
the.link.is.11/16".(17mm)..Thread.the.cable.end.halfway.
into.the.ball.link..Pass.the.cable.into.the.fuselage.through.
the.opening.
