•. To.complete.installation.and.wiring.hook-up.of.the.brushless.ESC,.connect.the.remaining.JST.male.connector.of.
the.battery.power.lead.Y-harness.to.the.female.JST.connector.of.the.3-in-1.control.unit ..Be.sure.to.then.secure.
the.battery.power.leads.of.the.brushless.ESC.and.3-in-1.so.that.they.cannot.come.into.contact.with.the.gears.or.
any.other.moving.parts,.and.so.that.you.can.readily.access.the.remaining.JST.female.connector.for.connecting.
the.battery.pack .
Now.that.you.have.completed.installation.of.the.optional.brushless.power.system,.it.will.be.necessary.to.check.
that.the.ESC.is.set.properly.to.ensure.maximum.performance,.and.that.the.motor.is.operating.in.the.correct.
direction ..Before.proceeding.with.these.checks,.however,.unplug.the.tail.motor.wires.from.the.3-in-1.control.unit.
making.note.of.their.direction.and.polarity.for.proper.re-installation.after.the.checks.are.complete ..Also,.remove.
the.main.rotor.blades.and.mounting.bolts/nuts.from.the.main.blade.grips.to.help.ensure.safety ..Then,.follow.these.
steps.(if.using.the.E-flite
®
.20-Amp.ESC):
•. Turn.the.transmitter.on.first.and.advance.the.throttle.stick.to.full.power ..Then,.after.placing.your.hand.on.the.
rotor.head.and.securing.the.helicopter.so.that.it.will.not.be.able.to.move.and.that.you.can.quickly.disconnect.
the.battery.if.power.to.the.motor.is.applied,.plug.the.battery.into.the.battery.lead.Y-harness.connected.to.the.
3-in-1.control.unit.and.brushless.ESC ..You.should.then.hear.the.beep.to.signal.power.up.of.the.brushless.ESC,.
followed.by.an.additional.beep.to.indicate.that.the.ESC.has.entered.the.programming.mode .
Note: Exercise extreme caution and care when programming the brushless ESC with the motor pinion
gear meshed properly to the main gear. Although the ESC is equipped with safe power-on software
and should not apply power to the motor, you must still be very careful. If, at any time, power to the
motor is applied and the rotor head begins to spin, unplug the battery immediately to prevent any
damage to the model and electronics, or even personal injury.
•. Follow.the.instructions.included.with.the.ESC.to.set.the.programming.for.the.brake.and.voltage.cutoff.to.the.
following:
Voltage Cutoff.–.Auto.Li-Po.ON
Note:.With.the.voltage.cutoff.programming.set.to.Auto.Li-Po.ON,.a.soft.cutoff.of.motor.power.(usually.noticeable.
as.a.quick.“pulsing”.of.motor.power.under.load).will.occur.when.the.voltage.of.the.3-cell.Li-Po.battery.pack.
reaches.9V.under.load ..This.is.generally.preferred.in.most.cases,.however,.you.can.disable.the.Auto.Li-Po.soft.
cutoff.entirely.by.setting.the.voltage.cutoff.programming.to.Auto.Ni-Cd/Ni-MH.ON ..In.this.mode,.soft.cutoff.of.
motor.power.will.not.occur.until.approximately.5 .0V.under.load,.even.when.using.a.3-cell.Li-Po.battery.pack.for.
power ..However,.this.means.you.must.exercise.extreme.care.to.prevent.over-discharging.the.Li-Po.battery.pack.
during.flight .
Brake.–.OFF
Note: It is extremely important that the motor brake programming of the ESC is disabled in order to
prevent damage to the main gear and other components.
Once.you.have.confirmed.that.the.ESC’s.programming.for.the.voltage.cutoff.and.braking.is.correct,..
disconnect.the.battery.from.the.power.leads ..You.will.now.need.to.also.confirm.that.the.motor.is.operating..
in.the.correct.direction .
•. Turn.the.transmitter.on.first.and.lower.the.throttle.stick.and.trim.completely ..Then,.plug.the.battery.into.
the.battery.lead.Y-harness.connected.to.the.3-in-1.control.unit.and.brushless.ESC ..You.should.then.almost.
immediately.hear.beeps.from.the.brushless.ESC.to.indicate.that.it.is.armed.and.ready.for.use .
Note: The brushless ESC will almost always arm before the -in-1 control unit. This is extremely
important to remember because the main motor will then run if the throttle stick is advanced, even if
the -in-1 has yet to arm. Be certain to exercise extreme caution when waiting for the -in-1 control
unit to arm, especially if the brushless ESC has already been armed.
