Setting.the.control.throws.for.your.ShowTime

does.require.some.attention.to.detail..To.correctly.set.

the.throws,.it.is.highly.suggested.to.use.the.following.

procedure.to.achieve.the.greatest.mechanical.advantage.

from.your.servos.

.

Step 1

Determine.the.maximum.amount.of.control.surface.throw.

from.the.throws.listed..Use.this.3D.throws.to.set.the.

maximum.amount.of.throw,.then.use.your.computer.radio.

for.the.lower.rate.listed.

.

Step 2

Set.the.Travel.Adjust.(ATV.on.Futaba.transmitter).to.about.

15%.under.the.max..(On.a.JR

®

.transmitter.that.is.135%.).

Make.sure.to.set.both.directions.during.this.process.

.

Step 3

Adjust.the.position.of.the.clevis.on.the.control.horn.and.

position.of.the.ball.link.on.the.servo.arm.to.achieve.the.

throw.decided.in.Step.1..It.is.highly.recommended.not.to.

change.the.position.on.the.servo.arm.unless.absolutely.

necessary..Use.Travel.Adjust.(ATV).to.finalize.the.throws..

That.is.why.we.left.a.little.margin.in.the.percentages.back.

in.Step.2.

.

Step 4

If.setting.a.dual.elevator.or.aileron,.match.the.linkage.

locations.used.back.in.Step.3..Increase.or.decrease.the.

Travel.Adjust.(ATV).a.few.points.as.necessary.to.fine-tune.

the.throws.to.match.up.left.and.right.sides.and.up.and.

down.throws.so.all.is.symmetrical.
This.is.all.necessary.to.tune.the.mechanical.advantage..

as.good.as.possible..When.setting.up.a.model.for.3D,..

the.mechanical.advantage.will.be.less.because.of.the..

large.throws,.and.thus.the.servo.will.work.harder.and..

wear.faster..Using.an.insufficient.servo.for.the.job,.or.

trying.to.get.too.much.throw,.will.cause.something.to..

fail,.probably.the.servo.

There.isn’t.an.exact.geometry.to.the.linkage,.as.it.depends.

on.how.much.throw.each.individual.modeler.requires..

The.linkage.geometry.should.always.be.maximized.so.the.

servo.isn’t.working.any.harder.than.it.has.to.
